It helps that China is a major producer of "rare earth" metals - that's the stuff you need for the accumulators. So they don't have a problem to get the accumulators in massive quantities.


Rare earths(lanthanum specifically) are only required for NiMH batteries. Li-ions are made up of common elements.

Electric motors on the other hand work much better with added rare earths, although it's still not a strict requirement.
