テスラだけじゃないコバルトフリーバッテリー。中国SVoltのバッテリーについて書かれてました。NMCがベースで、やはり単結晶ということらしい。
(以下、一部抜粋)
SVolt batteries use layered lithium nickel manganese oxide. It is like a film. Instead of rolling it, SVolt folds it back and forth. That makes it have a square format instead of a round one. That alone helps the battery have 5 percent more energy density, and another 10 percent increase in durability, according to the company.
