Leaves out: - time to recharge - materials industrial scaling (eliminates/reduces nickel and/or cobalt and/or lithium) - can be scaled up to a large battery

Leaves out: - time to recharge - materials industrial scaling (eliminates/reduces nickel and/or cobalt and/or lithium) - can be scaled up to a large battery (so many solid state batteries are these small demo cells, and an action car-worthy one that is 100x bigger never materializes - cooling requirements/support equipment reduce overall pack density (LFP and I think sodium ion do not require cooling systems, which substantially closes the battery density at pack level with nickel/cobalt chemistries
