I can’t ever seem to find it, but does someone have that checklist of the “oh you’ve invented a great new battery, here are the issues?” This one will probably

  Expensive is main problem with these things and that's because cracking solid state for mass production has proven to be really tricky. Otherwise, these things are pretty near ideal. Higher cycle life and power density with pretty much the same materials as standard lipo cells.

    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
