Interesting IF true. There have been heaps of "game changers" pop up and basically all have fizzled, I'll remain skeptical until it's actually shown to work as advertised. Still doesn't solve the really big problems with EVs though, in that the electricity infrastructure is not designed to handle the load of multiple vehicles charging simultaneously. If these batteries were shown to be safe, cheap and reliable, it could be possible to have a battery at home, that charges during low demand periods, which is then used to reduce the load when charging an EV and could be very good for solar/battery setups on a domestic scale. All sounds a bit unicorn farts to me though.
