Why not just use LFP or iron based battery chemistry? Prismatic cells can be used. The car has to be designed to accommodate a physically large pack for good range.

Combustion engine efficiency improved and emissions dropped a lot over the years, even with no fundamental breakthroughs either. A lot of money was spent.

Tesla has already shifted the majority of their cars to use LFP AFAIK. It's good enough for 250+ miles of range.
Also can maintain 100% SOC without causing excessive cell degradation. Solid chemistry for lower range vehicles.
China has a complete monopoly on LFP battery manufacturing. No incentives to lower price. Once other manufacturers come online, we should see price improvements. Biden’s DPA announcement last week gets the ball rolling
