The idea that the West will make our own batteries is a mirage. These things will always be made in the cheapest countries. All other factories will likely shut down.
The first of many. I think all car companies will abandon having dedicated platforms just for large BEVs. It is a tiny market after all. Even small car platforms will likely shift towards fuel agnosticism, so that BEVs can be made alongside hybrids and PHEVs. Pure BEVs will shrink to a very niche sooner or later.
