I look at this at solving a big problem in multiple ways! It would eliminate you having to drop 20 grand plus to replace battery car batteries!

It may help the power storage issues with solar and wind! And it may keep millions of lithium batteries out of the landfills!

Seems like scalability may not be a big issue because it could mesh right in with the way we make the millions of batteries that are currently being made!

It also help save some rain forest destruction for Lithium mining!
