I feel like what we really need for EV cars is a SpaceX like move towards simpler materials and chemistry (steel for example instead of complex materials), even at the cost of lesser performance. At this point higher manufacturing scale / cheaper to produce / less toxic is possibly much more impactful than extreme densities for energy storage tech. These can also be used for more stationary usage (domestic, grid). Maybe also rethinking infrastructure to make shorter point-to-point travels sensible, so that we don't keep seeking higher and higher capacities?
