Under modern physics, Lithium is pretty much the best possible chemical to build batteries out of. Anything else that might be better won’t be a chemical battery, and it’s not like there’s any reason to suspect some new magic thing will be created like a pocket-size fusion reactor that will make chemical batteries totally obsolete any time soon. Decades more of lithium batteries being relevant are as close to guaranteed as can be.

Lithium is pretty much the best possible chemical to build batteries out of. Nickel iron batteries, while heavier and less energy dense have virtually infinite lifespan. As such it is a far better battery for home power walls than lithium.

> Lithium is pretty much the best possible chemical to build batteries out of. Depends on how you define "best". Likely the highest possible short-term energy density, yes, but that isn't the only thing we might want out of a battery. "Doesn't catch fire" is one of the areas where the highest-energy lithium battery chemistries are far from the best, for instance.

Sodium batteries? Of course it depends on their use a bit.
