Donut Lab Unveils First Practical Fully Solid‑State Battery at CES 2026
WHY IT MATTERS
The announcement makes Donut Lab the sole producer of a practical fully solid‑state battery, potentially reshaping competition in electric‑vehicle and energy‑storage markets.
What happened
At CES 2026, Donut Lab announced its solid‑state battery, a milestone that has drawn both admiration and criticism for its performance claims. The company’s presentation marked the first time a fully solid‑state battery has entered production, a status no other firm currently holds.
Industry observers noted that while competitors such as Quantumscape have pursued solid‑state designs, none have achieved a commercially viable product. The reveal has sparked debate over the battery’s claimed metrics and the feasibility of scaling the technology.
Donut Lab’s entry into production positions it as a potential leader in the next generation of electric‑vehicle and stationary storage solutions.
