Yes, Musk said something like that a few weeks ago in September.[1] Musk says a lot of things. As of August 2025, Tesla's position was that the old technology plus expected improvement was good enough.[2] There was a rumor a few months ago that Tesla had bought Quantumscape. But that deal does not seem to have happened. Quantumscape is still publicly traded. Ticker symbol QS. Up 350% this year. Latest deal is a partnership with Murata for ceramic separators. They made enough sample batteries to power a motorcycle in Dubai. All the serious players can make high-cost samples now.
