Huge leap forward if the process is in the same ballpark expense wise. Being able to reduce a cars battery by 50% would reduce the prices by at least 5k, and likely have longer range because of the reduced weight.
Edit : still very experimental. Battery only retains that energy density for 300 charges. This is an improvement from an earlier 50 cycles, but not really viable either.
