The internet is all about “China Bad” so calling it China Battery is a way to depreciate this obviously positive discovery.

Sodium ion batteries are already in cars in China, this iteration is even safer. You should read the article.

Na+ batteries are really cool tech, and with a few more iterations of R&D they can potentially replace Li+ batteries, removing the need for rare earth elements that are toxic to people and the environment, dangerous to extract, and more often than not extracted by child slave labor (such as in Xinjiang and Congo).

It doesn't matter how you feel about China, although framing Na+ as "China's battery" is problematic for other reasons.
