The next best thing maybe sodium. Keep a close eye on what CATL are doing, and Faradion who were bought by Reliant, and possibly Natron. There’s absolutely no problem scaling sodium and CATL claim the same equipment developed for lithium can be used. In the same way NMC batteries are used for high-end EVs and LFP is being used for lower end EVs today, there could be a third rung using sodium in future. Sodium would also be a good candidate to replace lithium in stationary batteries where energy density not so important.
