I would love to have such batteries but I'm not sure we need them. Doesn't hot-swapping effectively achieve net charge rates faster than discharge? I can see why people might be less interested in hot-swapping for personal vehicles, but why isn't hot-swap on the table for buses and cab fleets? Is it because few people are willing to invest in R&D and infrastructure when sufficient batteries seem to be just around the corner?

Tesla tried to do the hot swap, and it presented a few problems. First, the infrastructure cost is massive. You have to keep an inventory of expensive parts (the battery) on hand. Tesla tried to fix this by having you set an appointment, but that eliminated the whole point of hot swapping: convenience. It's also harder to put a warranty on a battery if you're swapping them all the time. What if you get a dud swapped into your vehicle?
