Nickel–hydrogen batteries are interesting (en.wikipedia.org)

Lithium-ion is what the capitalists want you to use.

Nickel-hydrogen is three times heavier per unit of energy stored. Oh no. Sounds terrible. But it's –

Cheap. $83 per kilowatt-hour (https://www.pnas.org/doi/10.1073/pnas.1809344115)
Lasts 20,000 cycles compared to 400-1200 for lithium-ion, so far fewer will have to be produced and disposed of.
Materials. This is the big one. Lithium is rare. It costs a lot of energy to mine, and mining produces a lot of wastewater and CIA coups. Nickel is abundant and cheaper, and causes less damage.

Nickely-hydrogen batteries are for applications where you want something good enough and care about the planet. Lithium-ion is when you need luxury and don't care about externalities.

These battery's are heavy by comparison and take up volume due to the pressure vessels for the gas, they also don't form dentrites in the same way and are very serviceable, its more logical based on its characteristics to use in low maintenance environments like space or like grid power storage or honestly at home back ups, you will be able gets these installed residential as a company is reviving the old nasa pats. The real reason space people loves these is they opporate in very wide temp ranges like space.

That company is enerVenue

Lithium current rarity in based on proven deposits, the united States does have massive Lithium deposits problem is our nepotism-baby elites cant write industrial policy to make the public purse take the brunt of the risk in mining Lithium in the states, its also very environmentally not great but are deposits are in the middle of the desert with no water near San deigo, Northern Arizona, Middle of utah. It's dried up salt lake beds where the salt lakes gather various heavy compounds that don't evaporate with the water, not all salt lake beds are heavy in Lithium salts. Lithium is infinitely recyclable but just like aluminum its very energy intensive to get new aluminum but not already purified coke cans or industrial waste.

Im just gonna link the libtared engineer video https://youtu.be/2zG-ZrC4BO0?si=NfnBPRMsuYzrX4pI
