I've been hearing about these for a few years now. Huge if they work out at a large scale.

    Maybe they will make a potassium battery, K?

    Maybe, but I want to see Uranium batteries go mainstream, how 'bout U?

    Sodium-Ion is already in production at CATL. Been for about half a year if I recall. It's slightly less dense than LFP but it's cheaper and promises to get cheaper yet.

    The advantage of Sodium -Ion is that it's cheap, abundant, safe, and can cycle. It's mainly used where large capacities are needed. So industrial, grid scale, stationary types of storage.

    It's significantly less dense.

    It's close enough to already be in use in some chinese cars. But definitely better for stationary use cases where density matters less.
