That's a fair point, I can't see them as plentiful as oil, coal and natural gas though. The cost to mine lithium, etc. will not come down because these things are already mined by children in 3rd world countries. Unless you get robots to mine the stuff then I don't see how the price comes down.

There is a German company who was working on a sulfur battery using industrial waste - that sounds pretty cool. Of course now that Germany is de-industrializing that tech might not be here soon. Someone does need to develop a better battery, that's the biggest limiting factor.

There's a heck of a lot of amazing things going on with batteries.

In the lithium space you can get rid of/minimize the use of nickel and cobalt, the two most ethically difficult minerals to source by using LiFePO4 whenever possible.

Sodium is a potential replacement for lithium,providing they can improve the longevity to 1000-3000+ cycles.

A functional NaFePO4 battery uses materials that are abundant.
