I think you are seeing this as racism when it is just some old good skepticism about a country that is famous for faking everything.

Maybe they really done what they say, or maybe it is just some proof of concept that need to be ported, if possible, to a viable product stage or maybe it is just a fake, we will see.

Its not even like "China" invented a new battery tech. It's some battery plant in China which is the place where most batteries are created that's innovated on a design.

There are battery plants in Atlanta, Georgia and Heide, Germany who are pursuing similar advancements. They just don't have the money or the manpower equal to their Chinese peers.
