> Hopefully in 2-4 years we get the following IMO, current LFP batteries are already "good enough" and "cheap enough" for 80% of car sales. Reportly in 2021 China, 5000-cycle LFP at ~$70/khw. Chop off 1000 cycles, add 20% price margins, and it is still good enough. If you could conjure up x10 manufacturing scale, you would still sell every single cell. It will be easier to improve charging infra, that to improve NMC or stablize sodium. /end of rant

totally agree, but lithium supply may still block the REALLY big volumes, so 160 wh/kg sodium ion being as good as LFP from a year or two back means that isn't an issue. At this point, it should be more mundane factory scaling problems. The world governments really need to get onboard with pushing worldwide manufacturing of these cells and modules. Tesla's Berlin delays were shameful. If you are running coal plants, you as a government can't say anything about environmental damage from a new BEV or battery plant with a straight face. I'm thankful that at least science and technology have given humanity a path forward that is clearly economically superior, because it is clear that humanity's collective political governance is incompetent. The fact you can take decades of global warming science, point out the end state and dangers, and the effective intelligence of worldwide leaders over that time is less than the intellectual and logical capacity of a third grader, even one that has missed their nap, is one of the most depressing things in the world. I'm loathe to credit the Chinese government with anything based on their current leadership's autocratic and genocidal leanings, but their policies subsidizing battery and solar cell production have been the only effective governmental level environmental policy in the global warming era.
