"Batteries are terrible for long term storage, namely they are toxic"
Only some are toxic. But can you name the poison or danger with saltwater batteries?

- smaudet 3y agoYes, there are excellent non-"battery" technologies. I'm explicitly talking about the high capacity chemical batteries everyone's crazy for these days.

"Chinese automaker Yiwei debuted the first sodium-ion battery-powered car in 2023. It uses JAC Group’s UE module technology, which is similar to CATL's cell-to-pack design.[82] The car has a 23.2 kWh battery pack with a CLTC range of 230 kilometres (140 mi)." And for grid storage, "slightly bigger size" really doesn't matter.
