The problem with batteries for EVs is very simple. They have to be relatively safe in a very, very, rough environment, as in down to -50F, up to +130F, and survive crashes at least as well as gasoline cars. And that’s not even getting into performance requirements.
Not easy to do, so most washout, but only after sucking some IPO type money first.
Most EVs are being used in relatively warm, dry Southern California. How will they do when there is widespread use in winter states with much snow, cold and heavily salted roads. would you drive your two year old EV home in a snow storm, park in a garage attached to you house, attach the recharger, tuck your kids in for the night and then go to sleep?

A friend in the automotive industry said they want Near NASA specs for a competitive mass-market price.

Another real problem with batteries is where do you get the electricity to charge the batteries. Won’t be solar. Won’t be wind. Won’t be nuclear. So, what’s left?
