I think it's just battery tech that will put EVs over the edge. Solid state batteries looks promising and will change everything.

  Solid state batteries are like fusion: always a few years away. When you look at what's happening in the market solid state batteries are unlikely to be significant. The big promise of solid state was: higher energy density and lower probability of fires. Turns out that those are already good enough for cars and energy storage (i.e. 90% use case for battery cells). What is most important now is scale (being able to make terawatts of batteries) and low cost. That's why LFP batteries are quickly gaining market share: they are less energy dense than currently most popular nickel batteries, but significantly cheaper, less likely to catch fire, have more cycles (longer lifetime) no nickel bottleneck and they are good enough for base Tesla models (Model 3 and Y). If there's technology breakthrough to monitor, it would be sodium batteries. They replace lithium (currently in short supply) with sodium i.e. salt - one of the most abundant materials. They could be the cost and scale breakthrough 5-10 years from now. See: https://electrek.co/2022/07/14/sodium-ion-battery-breakthrough/ https://electrek.co/2022/07/14/sodium-ion-battery-breakthrou...

    It would be too bad if it never hits a breakthrough. Current batteries need those expensive metals and are not the safest, not to mention the battery life. SSBs seem like they improve these greatly.
