With ICE, the engine is the industry. With EVs, the secret sauce is the battery. Not saying the other parts are easy. But the core of the value add has shifted upstream. And in that domain, China absolutely dominates.
> ... has about 70% of the world’s production capacity of cathodes (the part of the cell that receives electrons) and more than 80% of anodes (the part that releases electrons on discharge), and well over half of electrolyte and separator output. Those parts come together to make a lithium-ion battery, more than three quarters of which are made in China and mostly by just two firms — Contemporary Amperex Technology Co. Ltd. and BYD Co.
Tesla using CATL batteries in their entry level Model 3 is a huge breakthrough for Chinese battery manufacturers.
No points to drivetrain?
None that I've seen. Or at least, none that are proprietary to a single battery electric manufacturer to the extent of posing a moat such as engines or batteries. (This is partly a curse of electric motors' versatility compared with ICE engines, which don't scale to alternate applications as easily.)
