Except for the mining of the raw materials and manufacturing of the batteries... Anyway, they may be on track to solve one of the issues of EVs.
...and the issue of where the electricity for charging them will come from.
Toyota has been doing extensive research on solid state batteries and will be using them in their ev/hybrid lineups. Don’t have the lithium fire hazard as well as other issues.
10 years ago I bought a boatload of A123 (LiFePO4) cells for ebike battery pack use. Still using them.
