HiNa supplied sodium-ion batteries for JAC Motors in 2023. Early batteries had lower gravimetric energy density (145 Wh/kg) and volumetric energy density (330 Wh/liter) than LFP, but sodium-ion batteries have already improved since then. They have outstanding temperature range, yielding 88% retention at -20°C. For reference, the discharge capacity of NMC at 0°C, −10°C and −20°C is only 80%, 53%, and 23% of that at 25°C. The HiNa batteries had a cycle life of 4,500 cycles with 83% retention and a 2C charge rate, but even better sodium-ion batteries are on their way.

...

These developments point the way to much more. The cost of sodium battery materials is much lower than for any lithium battery. There are no resource bottleneck materials like cobalt or lithium to contend with. In addition, aluminum can be used for electrodes, whereas lithium requires copper for one of the electrodes. Carbon or graphite and separator materials will be similar, but in all other respects, sodium has much lower material costs. Compared to LFP, sodium does not require phosphorous, a substance that is almost exclusively sourced from one state in north Africa, nor lithium, a relatively abundant but more expensive substance than sodium. LFP cannot compete on material costs or temperature range, and both BYD and CATL expect to phase it out first in energy storage. ‌

    Nothing factually wrong with the article, but it has this sound of "this technology will solve all our problems" to it that I find highly problematic. Seven out of nine planetary boundaries are exceeded, climate change just being one of them. And all of them are exceeded because of our wasteful and growth-oriented way of life.

    No, it's not. Not seeing that it's capitalism is the reductive view. Instead of trying to type down a huge text while I'm tired, I'd like to introduce a 112 year-old text that still seems extremely relevant today:

    Moreover, capitalist production, by its very nature, cannot be restricted to such means of production as are produced by capitalist methods. Cheap elements of constant capital are essential to the individual capitalist who strives to increase his rate of profit. In addition, the very condition of continuous improvements in labour productivity as the most important method of increasing the rate of surplus value, is unrestricted utilisation of all substances and facilities afforded by nature and soil. To tolerate any restriction in this respect would be contrary to the very essence of capital, its whole mode of existence. After many centuries of development, the capitalist mode of production still constitutes only a fragment of total world production. Even in the small Continent of Europe, where it now chiefly prevails, it has not yet succeeded in dominating entire branches of production, such as peasant agriculture and the independent handicrafts; the same holds true, further, for large parts of North America and for a number of regions in the other continents. In general, capitalist production has hitherto been confined mainly to the countries in the temperate zone, whilst it made comparatively little progress in the East, for instance, and the South. Thus, if it were dependent exclusively, on elements of production obtainable within such narrow limits, its present level and indeed, its development in general would have been impossible. From the very beginning, the forms and laws of capitalist production aim to comprise the entire globe as a store of productive forces. Capital, impelled to appropriate productive forces for purposes of exploitation, ransacks the whole world, it procures its means of production from all corners of the earth, seizing them, if necessary by force, from all levels of civilisation and from all forms of society. The problem of the material elements of capitalist accumulation, far from being solved by the material form of the surplus value that has been produced, takes on quite a different aspect. It becomes necessary for capital progressively to dispose ever more fully of the whole globe, to acquire an unlimited choice of means of production, with regard to both quality and quantity, so as to find productive employment for the surplus value it has realised. From Rosa Luxemburg: The Accumulation of Capital, Chapter 26 - The Reproduction of Capital and Its Social Setting

    This passage is kind of an introduction to Rosa Luxemburg's definition of imperialism. Back then, capitalism was not yet developed in the whole world and she argued that simply because it's a question of survival for companies, these companies will push for the right to exploit the whole world. And now, 112 years later, I'm pretty sure we can agree that happened. And in the past few decades, when they can't expand spacially, now it's all about squeezing every last bit of profit from nature, the workers and the consumers.

    The particular ideology oligarchies are using to justify their rule is incidental.

    Here, we have a point of agreement. The USSR developed into something that was no better than capitalist states. In my opinion, that's because it's bureaucracy developed into something very similar to the burgeoisie in capitalism, resource hoarders led by self-interest.

    But I believe your answer built on another false dichotomy here. The alternative to capitalism I have in mind isn't a one-party state with central planning and communist aesthetics. I'm more of a proponent of decentralized power, dismantling the state and people governing their surroundings cooperatively.

    Personally when I say I want to ditch capitalism, the first thing I think of, among many, is simply about democratizing the workplace. Cooperatives have proven themselves to be superior than the current private model in a variety of metrics. If we reduce the defining characteristic of capitalism as needing capital to produce more capital, the current issue is that cooperative enterprises struggle to obtain the initial capital necessary to get started. Even though they have much greater success rates, banks have historically refused to give loans to these endeavers. There exists non profits to try and fill this void but its not enough.

    It makes a lot of sense, but I doubt we can have a rational debate about that. In short, people tend to be motivated by profit, so theoretically productivity goes up when the economic system rewards that.

    The root of the problem has little to do with the economic system, and it's like blaming bombs for war. The real problem is government structures that reward and encourage consolidation of power, both in the government itself and in the private sector. If you strip away capitalism, you just consolidate that power into the public sector, and for examples of that look at China and the USSR.

    I would think that people on Lemmy who likely left other social media due to centralization wouldn't be so enamored w/ more centralization in the government space. We need solutions that look like Lemmy in the public space to decentralize power so we don't run into this type of problem. I don't think there's a magical structure that fixes everything, and I don't even necessarily think that capitalism has to be the dominant economic system in play, I just think we need to come up with ideas on how to reduce the power of those at the top.

    Specific example of the US militaryWe should dramatically reduce the federal standing military, increase the National Guard to match, and put stricter limits on when the President can use the National Guard. IMO, the only way the President should access the National Guard is if one of the following happen:

    • governor explicitly yields control, or the state's legislature forces the governor to yield control
    • states vote with a super majority to declare war
    • legislative branch votes to declare war with a super majority

    That's it. The President would otherwise be left with a small standing military that's enough to deter or perhaps assist in peacekeeping, but nowhere near large enough to invade another country.

    I personally think we should embrace capitalism as it's decentralized by nature, unless forces centralize it, and then create rules that discourage/punish over-centralization. For example, I think small companies should have liability protections, and larger companies should lose it, such that lawsuits could target specific individuals in the organization instead of allowing the organization to be used as a shield. For example, if a company files bankruptcy and it's over a certain size (maybe $1B market cap? $100M?), then shareholders and top executives become responsible to cover whatever the debts are still unresolved after liquidation. If a crime is committed, it shouldn't simply result in a fine that's factored in as the cost of doing business, it should result in arrests. The problem isn't capitalism, it's corruption and protectionism.

    In short, people tend to be motivated by profit

    Only in a society that commodifies your existence and success based on the wealth you generate/hold

    Unless we're changing the definition of profit to status

  • source

  • hideshow 13 child comments
  • At a certain point, profit can turn to status, like with the super wealthy. Elon Musk seems to be pushing for $1T, not because the extra money matters, but because he wants the status of being the first to get there.

    But if you look at the quiet majority, many people will take more stressful roles because of the higher earning potential. So they're increasing their output specifically to get a better standard of living. Those types tend to be contractors, small business owners, and early stage startup employees.

    If you look at the alternative, such as China or the USSR, those who rise to the top aren't those with the highest productivity, but those most able to play the political game. If you look at a small engineering company, it's generally those with the most technical capability who rise through the ranks, but once you get to larger companies, higher roles generally get taken over by business types, i.e. those best able to play the business side of the political game. It's the same process, just with different mechanisms for gaining power.

    Any proper solution here needs to fix the problem of the wrong people getting to positions of power. The economic system isn't particularly relevant, other than setting the rules of the game. The best solution, IMO, is to make the rules of the game such that you get punished hard if you don't know what you're doing (i.e. you're a business type running an engineering firm firing top talent to cut quarterly costs), and you get rewarded if you do. If we actually put execs in jail for problems their businesses create, I think we'd quickly see companies like Boeing change their leadership to one that will prevent problems, such as someone w/ an engineering or safety background.

    That's why I think government and the economy should be as separate as possible, and in fact in an adversarial relationship. Bureaucrats should be rewarded for catching crime in the private sector, and private companies should have real incentives to keep everything above board. That can't happen when politicians are literally funded by the companies they're supposed to be regulating.

    Come on. Even animals are motivated by profit: getting more out of something than you put into it. Profit doesn’t have to mean “shareholder dividends.”

    It’s so naive to claim that it’s only society’s setup and status pressures that make us care about getting better things for less effort. As if that hasn’t been the aim of every individual AND every society since the dawn of time.

    The easiest way used to be to just plunder people. Take their shit. Now it’s your shit. Easier and faster than making the shit. Woohoo.

    Then trade entered the chat, and it was the first time that people started to think there might actually be a better way: that both parties could walk away from an exchange better off, and that it might be in each of their interests to keep the other alive.

    Yeah I'm only an archaeologist.

    I'd like to explain what you're missing in detail, but truthfully it would take a course in it of itself. I'll try to be concise.

    Simply put all evidence that we have points to humans living relatively egalitarian and peacefully for the majority of our history. We additionally have early evidence of trade.

    Now there is, with all things, nuance. For the past 10,000 or so years evidence points to humans being very violent to one another and we have seen an increase in social stratification. However, in the modern era violence is on a downward trend relative to the total human population. Social stratification is obviously not.

    Skeletal evidence is our best, but we also have evidence in the form of more traditional artifacts.

    To be clear I'm not saying we can tell you every human in a hunter gatherer group carried the same social status or that people never killed each other. Obviously not, but what I can tell you is that every member of the group had access to the same nutrition and that evidence of violent skeletal trauma is significantly less prevalent than after the advent of agriculture. There is also significant evidence of trade prior to evidence of mass warfare.

    Yay thank you for saying something instead of empty judgments. I think most of what you had to say is actually beside the point at issue, and to show how I’ll unpack this segment, which has a lot to say about this topic and what I am and am not saying.

    every member of the group had access to the same nutrition and that evidence of violent skeletal trauma is significantly less prevalent than after the advent of agriculture.

    Let’s go piece by piece.

    every member of the group

    Raiding is an inter group behavior not an intra group behavior so if this was meant to say “look humans were egalitarian they didn’t raid” it doesn’t say this at all.

    evidence of violent skeletal trauma is significantly less prevalent than after the advent of agriculture

    I believe this very much supports my point that violent raiding was a way of life. You said: there’s more violence after agriculture. Well, agriculture was the first time that anyone had valuable assets collected in one place: at harvest time. Agriculture freed up specialists to create items of value. More to take.

    Of course hunter gatherers exhibit less raiding: first of all dramatically fewer people are supportable without agriculture so there were simply fewer groups available to raid. And hunter gatherers live largely hand to mouth so there is no stockpile to plunder.

    Naturally as soon as there is something to raid, you see the evidence of that.

    So what about anything you said do you think contradicts the claim that humans have commonly raided one another for spoils throughout history? Are you going to tell me that slavery wasn’t a thing next?

    I think I need you to come to a point instead of just flashing your credentials. You’ve offered a lot of facts from the record but these must be interpreted. It’s that interpretation that makes you an archaeologist, not the shovel.

    My claim is that raiding other humans and taking their things was common, because humans want something for nothing and will exploit each other to get it - long before capitalism and conspicuous consumption made it fashionable. I would also offer you the bear that eats the honeycomb, the snake that eats the eggs. A cow mows down grass because it gains more energy by doing so than it spends: ergo profit. Everything is about profit and most of it is savage taking.

    Someone above wanted to claim that profit orientation is a modern aberration driven by capitalism’s status driven pressure cooker and that’s just garbage.

    My claim is that raiding other humans and taking their things was common

    This is shifting the goal posts. The statement I initially made was that humans for the majority of history were egalitarian and less violent. This is still true. This statement you provided is true to a specific portion of human history that does not make up the majority.

    If the argument is now that a society creating excess leads to violence and raiding we also have evidence of cultures that have not done that.

    There's also an issue with the argument that hunter gatherer societies had nothing of value to take. That idea relies heavily on our modern ideas on what is worth trying to take. For example sometimes people would travel, or possibly trade, with quarry sites hundreds of kilometers away. Having quality stone means being able to feed yourself and your group. Sounds quite valuable, but we don't see violence increase as you move away from these sites. The same can be said for virtually every limited resource in the distant past.

    See, above:

    In short, people tend to be motivated by profit

    Only in a society that commodifies your existence and success based on the wealth you generate/hold Unless we're changing the definition of profit to status

    This is what I’m rebutting. So you see, it’s not shifting the goalposts at all. It’s staying on the topic of this comment chain. You trying to claim that humans have been majority peaceable is in fact drifting from the topic. If we’ve been majority peaceable but with plenty of profit oriented violence, that’s all that’s relevant.

    The debate is whether profit appears with the advent of modern capitalism. I said people have been raiding each other for profit since the beginning of time. You failed to say anything that invalidates this.

  • like, i get your point but i think you're wrong.

    people are greedy because it worked well for them in the past. i.e., people have built empires and expanded them throughout history and because sometimes that worked out well for those people, they think back fondly of it and that's why you have people trying to become "great empires" today.

    it's not that complicated, people have a cultural memory that reaches far back for hundreds of years at least. it's however also noteworthy that empires are the historical exception, not the rule, like, if you look at medieval europe (which spanned a long time), you had very few "big" empires and mostly small local feudal lords. Because in those times empires simply didn't work out so well. So, people hold the balance between what works and what doesn't, and then that gets done.

    Well considering for the majority of humanity's existence we existed in largely egalitarian societies I think it's up to you to prove this is working.

    I'm not going to downplay modern medicine and our technological advancements. Capitalism had a role to play in that is just a shame kids in the 3rd world had to starve or die in mines for it to happen. I think we could've come up with a better system than that.

    the people can hold their politicians more easily accountable if the politicians live closer to the people.

    it's some kind of "pitchforks and torches" thing: In historical times it was usual that people simply walked up to the castle of the feudal lord and demanded improvements if their life was too shitty or if they were treated too unfairly. That was possible because the feudal lord mostly lived within walking distance of where the peasants lived, like, maybe in the next village or sth, but not farther than that in most cases. As a consequence, feudal lords had a very significant interest in being on good terms with their neighbours and keeping the people happy enough so they won't start a revolt over high taxes or sth.

    Today, that's not possible because all those politicians that decide the law (and therefore our fate) live far-away (thousands of miles!) in places that neither you or me can ever personally visit. Hence, there is no accountability. We need to shift power back to the local levels; only that way we can personally ensure our wellbeing.

    We need to shift power back to the local levels; only that way we can personally ensure our wellbeing.

    I agree with the conclusion, but not how you got there.

    My Senators and House rep live pretty close to me, like 15 minutes away driving, so I could go visit them if I wanted. They spend a lot of time in DC, but they come back several times throughout the year.

    The issue, IMO, isn't where they sleep, but that they can't easily be removed from office. Our districts are gerrymandered to the point that the main party usually wins with 20%+ margin. Why care about constituents if reelection is all but guaranteed? They could live next door to me and that wouldn't change their mind. If I assassinate a rep, I'll go to jail and the replacement will likely be worse. They're more accountable to their party and donors than their constituents.

    But yes, I very much do believe decisions should be made locally because party affiliation matters far less. My local legislature behaves very differently from the federal Congress, not because of where people live, but because they're much more easily replaced and they can't hide behind other reps from other states and argue that their decisions are careful chess moves to get what really matters passed.

  • That's the thing, mine aren't easily replaced and it's not because they live in DC much of the year, but because my district is gerrymandered, and that seems to be true for most districts in the country. Only a fraction of races are actually competitive after the primary, and there's not going to be a primary to replace a sitting rep unless they piss off the party.

    If we simply made state politics more impactful than federal, parties would move their focus to rigging state elections.

    The issue, IMO, is there's too much incentive to rig politics. Government interferes so much in all aspects of life and is so powerful that it will absolutely attract money. If we shift more of that to the courts, now that money would need to focus on everyday people, which I think is an improvement.

    It’s worth reminding ourselves that this is exactly what we are at Lemmy to do. Where capitalism produced Reddit, communitarianism produced Lemmy. The best effort of both systems is now live and the two are competing head to head. We win when Lemmy is the superior option for enough people that we actually start bleeding Reddit out.

  • This argument is very different from the argument I'm talking about. Lemmy isn't a government, nor does it attempt to fill that role (as much as my instance's "Agora" community wants to think it does), so whether Lemmy is successful doesn't give any insight into whether a more decentralized form of government could be successful.

    communitarianism produced Lemmy

    That's a pretty generous description.

    A more accurate description, IMO, is that two people wanted a safe space for their extremist community (tankies), and they had a working version at the time that a lot of people were frustrated with Reddit. Those two are still running the project, and they moderate their instances very tightly. But many people outside that community came and decided to make something good out of it, which is why additional instances popped up run by people with different motivations from the original pair.

    So I don't think communitarianism produced Lemmy, at least not initially, but it did help turn Lemmy into what it is today.

    We win when Lemmy is the superior option for enough people that we actually start bleeding Reddit out.

    I don't think that's necessarily true. I think we have already won in that people choose to stay here over returning to Reddit or whatever social media platform they came from. That said, active users on Lemmy seems to be steadily dropping, which is a bummer, but I'm still able to have decent discussions here, so it's working for me.

    As bullish as I am on Sodium-ion batteries, only very recently did researchers figure out how to boost the charge capacity, making any attempted commercial models in use so far nice, but not the final form where normies are buying them from Home Depot.

    The Sehol car mentioned is a niche configuration of a common model, because the Li-ion model goes farther between charges. Other than the launch in 2023, and articles recycling the same info, find me 1 article that doesn't use words like "could" or "will" or "might" about sales of this model? Same thing for the BYD Seagull with Na-ion batteries. It's all greenwashing news where if you dig at it even slightly, you see how not real any of it is.

    You can buy sodium batteries from AliExpress. It's been available for a while. I was thinking about ordering a few but I ended up spending my hobby budget elsewhere. There's no economies of scale yet for sodium battery tech. You can get the battery but there is zero electronics available for it. Mainly you'd have to design your own charger and battery management modules. That's out of my pay grade. I've been waiting for Chinese engineers to mass produce such things.

    I can't resist cancelling the units even though it doesn't actually make sense because it's a capacity not a volume, as it were, but that's a 3.6kw factory!

    3.6 MW even. :)

    3.6 kW is what a 50cc internal combustion engine typically produces

    Here's my working. There are about 31.56 million seconds in a year, which I rounded to 30 million, and so

    30 GWh/year
    = 30x10^9 Wh / year
    ~ 30x10^9 Wh / 30x10^6 s
    = 10^3 Wh/s
    = 1 kWh / s
    = 3600 kWs / s
    = 3.6 kw

    I used the duckduckgo autocalculator just now, and 30/31.56*3.6 is about 3.4, so it's much closer to 3.4kW.

    (It's not power output, it's manufactured storage output. I think of it as like a factory that produces 3.4 litre capacity jugs per second, but they're not jugs, they're actually batteries. Big ones.)

    They could make a 120kWh battery (which would give a family car a range in the region of 450 miles) every two minutes.

    Yeah, I want to buy a car w/ reduced range at substantially lower prices, but I can't do that right now. Give me a sub-$20k option to get to work and back and then I'll get excited about the tech.

    Right, used cars are feasible, I'm talking about new cars. A sub-$20k new commuter should be possible w/ sodium ion batteries.

    Buying new cars is stupid. You wasted several thousand just by driving it out of the dealership. Let someone else do that and buy it a year later with low milage and ten grand off.

    And the Nissan leaf is an absolute joy to drive.

    I buy used cars exclusively. A used EV that retails under $20k new will be very affordable used.

    My point isn't that used cars don't exist under $20k, my point is that sodium ion batteries are supposed to be way cheaper than lithium ion batteries, and they're more than sufficient for a commuter. I want those available where I live.

    the problem is that North American consumers don't rationally buy vehicles. They buy $60,000 pickups to commute to office jobs, and they want 500 mile EVs because of "range anxiety" which is likely going to be in the next DVM.

    Sodium batteries have a lower energy density, but they work better in cold temps. They are also inherently safer and last longer, longer than a car will last so they can be reused in the home battery market. Sodium is far less energy intensive to mine.

    Of course, the big problem in NA is all this tech is from China, while we just spent billions on lithium cells. China is making 8K TVs and we're just tooling up to make 12" Black and white TVs.

  • And that's why the tariff situation pisses me off. I get that we don't want subsidized EVs from China to ruin the local EV market, but we should at least take the tech that works and implement it here. Maybe we can estimate the amount of subsidies the Chinese government gives its EV market and charge that on import, idk, I'm not an economist so I don't know what that would look like. I just know I want an inexpensive EV for commuting and I only need to go about 50-60 miles in a given day (call it 100 if I need to run some errands after work). If I can get that, during winter, for a low price, I'll buy.

    What car anywhere is sub $20k?

  • The Kia Soul is just over $20k, but not EV.

    The Nissan Leaf is about $30k w/ ~300 mile range (my local area's cheapest is $36k, but I guess that's because they don't carry base trims), and a replacement battery is something like $5-10k, depending on size. That's pretty close to that $20k target, and given that the Soul is around that $20k price, I could see a manufacturer getting a sodium-ion based EV with limited range (say, 100-150 miles) right around $20k.

    The Slate truck is targeting $25k or so, so if the battery prices are similar to the Leaf, that's your $20k vehicle right there.

    The sub is about technology, not industry. Also, look at the advances in battery technology in the last 30 years. There have only been 3 notable technology advances in the last 40 years from a consumer perspective, but there have been significant advances within each of those major technology changes, resulting in Wh/kg increasing by 6 to 10 times and $/Wh dropping about 99%.

    If you want to hear about things that could happen or are about to start happening in industry, this is the right community. If you want to know what you can buy tomorrow, try Amazon.

    Feels weird to gatekeep that - the des says 'news or articles' so an article about some ancient tech isn't for this community?

    I understand it as anything tech related, that explains/talks about technology, manufacturing tech included.

    The 'not industry' part as in macroeconomics & geopolitical stuff - I agree on that.

    The point is not about this particular article, but the general attitude of that comment, which boils down to "Why is there an article about a technological breakthrough that may never pan out in my community about technology?" I feel like these guys would have complained about Newton's quaint ideas for a new way to use mathematics. The fact this particular article is about technology that is demonstrably taking off while they complain about articles on battery tech not being implemented is pretty next level.

    All good. I just keep seeing this all the time about batteries, simply because most of the technological advances are slow, cumulative, aggregate, and largely invisible to consumers. Then people complain about how none of these advances ever make it to market while ignoring, for example, how many pounds old, barely capable cell phones were compared to the functionality of smartphones these days that can run for a full day on a battery a fraction of the size we had for those old behemoths, all apparently without any of those breakthroughs making it to market. I mean, look at the first cell phone in this article. I suspect some advancements occurred in batteries between then and now.

    Oh, I'm fully aware how battery tech advanced and/or awkwardly staggered in some areas.
    Phones are a great example, the rise of capacities through diffident technologies were fast & very close for people to experience first hand.

    I just wish we would have started this push a century ago.

    Tesla, the company run by a nazi capitalist and which has a value so inflated it’s amazing it hasn’t imploded under its own weight, raises it’s prices and you’re blaming batteries? You do know that every saving a corporation makes goes towards profits and that they never lower their prices as long as people are buying(and even then, they refuse to most of the time)?

    There’s correlation not equalling causation and then there’s whatever the hell this is. Like one of the final bosses of that logical fallacy.

    It's not just Musk. All the legacy automakers switched fast to EVs because of the higher profit margins, and have been obfuscating the fact that at recent battery prices, EVs should cost less than ICE. To try and add value, they festoon the vehicles with pointless gadgetry and screens, which of course will all fail long before the battery. By Design.

    I'll take out of context quotes for $100, Alex.

    Those changes are over 40 years, only 13 years of which apply to your reference, and include only one component of a luxury vehicle. Also, the current base price for a Tesla Model S that it showed me was $150k. If we apply inflation to $140k since 2012 ($150k minus the $10k you said), we get a value of $197k. So, $47k cheaper in 2025 dollars.

    I suppose you blame battery prices for why McDonalds costs more, too?

    But Elon told us EVs cost more than ICE because of battery costs. There are hundreds less components in EV versus ICE, and there could be even less if they removed the pointless gadgetry. As for the McDonalds comment, which makes no sense, maybe loosen your ponytail elastic.

    The McDonalds point is in reference to inflation, which will certainly have an impact on the cost of vehicles. And I feel like you don't grasp the concept of a luxury vehicle. By definition, it has more than the basics. This could be why my EV cost less than $20k used and a Model S costs $151k new. No ponytail, but I don't expect having one would hinder my basic math, economics, or English comprehension skills.

    look at EV prices in china for a more accurate depiction of the battery progress that is being made

    apparently the government EV subsidy for outright purchases ended in 2022, but they're good enough at the manufacturing now that EVs are still exceptionally cheap. 70-80% of world lithium-ion production also takes place in China, so it makes sense.

    There's a lot of reasons that I don't like the Chinese government, but they have been doing a whole lot better than the rest of the world with investment into the future of technology from what I've seen. The number of top-rated CS and EE schools in China is doing a whole lot on its own.

    I think it will displace lead acid use case first where its lighter in the same form factor and more resilient in cold. Already seeing small engine batteries. You can buy a car battery today on amazon but i understand it doesn't play welll with alternator regulators, but that can change with retrofits or automakers adapting smarter regulators.

    Sodium ion is great, but

    While batteries have enabled passenger car developments, they have been somewhat stymied in large mobile power applications like shipping and electric trucks. That day is gone now. At these costs, electric shipping is achievable and the debate over alternative fuels will fall off quickly as applications are realized.

    heavy transport is not the right application. Very heavy, and LFP has similar advantages while only being medium heavy. heating vehicle batteries is a solved problem.

    https://micapower.en.made-in-china.com/product/YtVpSrTCuEkm/China-Grade-a-Catl-EV-Sodium-Ion-Battery-100ah-3-0V-Sodium-Na-Ion-Battery-Cell-for-EV-Smart-Storage-System-off-Grid-Power-Emergency-Backup-Power-Automotive-and-Marin.html

    Great that you can get a home power 48v 33.6kwh system for well under $3000. (afaik, it comes with connector plates for 112x100ahx3v for $2340. Don't know about shipping or a box)

    For 10% more, on that site, LFP is 33% lighter. Can affect shipping costs.

    Sodium ion has extra applications/advantages. Not requiring a heated space could place them under solar panels in the field.

    At $100/kwh or less, "retail", offgrid even oversized solar+ batteries is far cheaper than any utility service. At low charge/discharge rates (4+ hour charge from solar, and 16 hours of discharge (even with 0.25c peak discharge), 10000 cycles is achievable with both chemistries. $0.01/kwh/cycle.
