Donut Lab's Solid-State Battery Turns Heads at CES 2026 With New Performance Data

At CES 2026, Donut Lab introduced a fully solid-state battery that has drawn both admiration and skepticism. While several companies have chased this technology, nobody else has brought a practical, production-ready solid-state battery to market yet.

The company’s latest performance tests have added fuel to the conversation. Details are still limited, but the results suggest Donut Lab may have moved past the laboratory stage. The announcement has left some observers impressed and others doubtful about the claims.

For now, the solid-state battery landscape remains a work in progress. Donut Lab’s showing at CES 2026 has at least made it a name to watch in the race toward next-generation energy storage.
