Thanks for the input! You’re absolutely right — aluminum-air batteries have limitations, like being non-rechargeable and producing aluminum hydroxide as a by-product, which can be a challenge for processing. That’s one of the reasons I love the innovation happening in the battery space, as there are always trade-offs with different technologies.

However, aluminum-air batteries still have great potential for emergency power and off-grid applications, where long-term rechargeability isn’t a primary concern. They’re lightweight, environmentally friendly, and great for scenarios where power is needed for a short period, like during power outages or in remote locations.> I did some googling and aluminum air seems to have the huge problem of being non rechargeable and leaving a hard to process by-product of aluminum hydroxide.

I’ve wanted to make/buy a Nickel Iron (Edison battery) for years. They are practically infinitely rechargeable. The only downside is size and weight. They don’t get any investments because it’s only good for home power and infinite lifespan is bad for business.
