> However EVs and green-tech are analagous to the XFEL path, they built from scratch and leapt over the competition that was happy to sit on it's existing profitable tech instead.

I'm not convinced Chinese EVs are technologically better. They've just command economied demand and reduced costs via mass production. The technology seems pretty inline with anything available in the West but demand isn't there to take advantage of scale. China is ahead in EVs by metric of quantity for sure but I don't think they're got next gen battery tech they are keeping secret.

Making batteries for $80/kWh IS the next gen tech. I’m pretty sure China invented lipo (EDIT: I meant lfp) (at least they’re the only ones making it) and they’re currently pushing ahead on sodium ion. They are also the ones who have pushed lithium ion to the point it is today. My first EV was a Nissan Leaf that cost 40 grand and could drive 80 miles. Now you can buy 300-mile cars for about that. That was all China’s doing and nearly every EV on the road today uses their batteries.

They have done to the battery market exactly what Taiwan did to the chip market. You can buy an EV made anywhere the same way you can buy a laptop made anywhere. But guess where the chips and batteries were made.

They didn't invent LiPo (and you probably don't want those in a car), nor did they invent LFP (LiFePO4) but they did license it when no one else wanted to and turned it into probably the best EV battery tech you can buy today. They didn't innovate a ton on the chemistry but they did on the packaging side, BYD and CATLs structural pack designs exploit the low thermal runaway characteristics in a way that wouldn't be safe for NMC etc to reach near parity on density but with better longevity and cost.

They will be the first to sodium ion and solid state though.

It's kind of ironic that BMW pushed CATL into the EV market [1].
