While researching Chinese EVs I came across articles about abandoned EVs, the article claimed it was because they were made obsolete (they have roughly 100 mile range or less) so they were abandoned for the newer cheaper models with 3-5x that range, that problem is probably gong to be a bigger one to tackle than Chinese EV longevity, which supposedly aims for roughly 200,000km lifecycle which is 125k miles (average ice car has a lifespan of 130k miles). It also showed me how close to production those batteries you are talking about are, there's a bold claim that the battery could be good for 2 million kilometers, if it's even on the same order of magnitude of that, it would make so many EVs 'obsolete'.
