In 2027-2028. Comment in the article: The big company who doesn't have a competitive product attempts to mess up the market by making bold announcements of fantastic products that are coming "soon". Everybody serious, except Tesla, has a solid-state battery program. Here's an overview of where various car makers are.[1] There are a few prototype cars running around on all solid state batteries now. The problem is developing a cheap production process. Most of the big players are saying first production vehicles in 2027, solid state technology takes over around 2030. There's an interim "semi solid state" technology that's already in some cars. It's one of those stopgap ideas destined to go away, like "mild hybrids".

We can get a picture of the cost problem from this.[1] Samsung is about to put tiny solid state batteries in their watches, rings, and earbuds, but they still cost too much for phones.

  That's a point. If solid state batteries are going to be a thing you'd expect to see them phones and laptops before cars.

    I don’t think that’s necessarily true. Cells in cars can be managed in ways cells in laptops and phones cannot, because of the built in redundancy. That might matter.

Tesla bought a solid-state battery company and also is running a research office dedicated to the subject, so I don't think you can say that Tesla has no solid-state battery program.

  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.

It's a Tesla fanboy/investor website. They used to have the $TSLA stock ticker right on the front page. Commentor opinions on any other car company are even more useless than the average internet opinion.
