I love the framing “…that has the US worried”, as if better battery technology isn’t a win for consumers everywhere, and the only people who are ‘worried’ are US battery manufacturers who haven’t kept up with technological advances, and the government who want to keep encouraging US companies to not use (objectively better) batteries from China.
It sounds like the ‘worry’ is “Our technology is years behind a political rival, and people are starting to notice”.
If this is actually a bad thing for me, as a consumer, and I’m mis-reading the situation, please feel free to educate me.
