What happened to sodium batteries or whatever, I thought that was the next step like 5 years ago.
They're in commercial use in China already. They have some disadvantages compared to lithium batteries as they don't hold as much charge, but they are a lot cheaper to make and don't require rare earth minerals.

Well I would have preferred it to be used as a stopgap for now leading to other discoveries like this proton battery. Cause it seems like lithium will be in use for another 10 years at this rate. The whole situation reminds me of graphene and how that is barely making any advancement either.
Graphene is being used in certain high sensitivity/quality sensor chips.
