I guess this announcement from VW got fast-tracked now that China is about to announce a ban on gas-powered vehicles
China, in turn probably wants to go forward with that not for environmental reasons, but because they have a near monopoly on the world's supply of rare earths (which the electric vehicle's batteries require) |

Rare earth elements are cerium (Ce), dysprosium (Dy), erbium (Er), europium (Eu), gadolinium (Gd), holmium (Ho), lanthanum (La), lutetium (Lu), neodymium (Nd), praseodymium (Pr), promethium (Pm), samarium (Sm), scandium (Sc), terbium (Tb), thulium (Tm), ytterbium (Yb) and yttrium (Y) (https://en.wikipedia.org/wiki/Rare-earth_element)
Lithium batteries generally require elements such as: Lithium, graphite (carbon), Nickel, Cobalt, Manganese, Aluminium, Oxygen.
None of these are rare earth minerals, and production of most of these elements is not concentrated in China. See https://electrek.co/2016/11/01/breakdown-raw-materials-tesla...
The powerful permanent magnets used in some EVs do require rare earth elements (e.g. neodymium), but many EV motors don't require permanent magnets at all. E.g. Tesla uses an induction motor (no permanent magnet required); whereas the Nissan Leaf does use permanent magnets (assuming https://en.wikipedia.org/wiki/Electric_vehicle#Electric_moto... is correct).
