New Haven fire officials said heavy smoke was visible after an e-scooter battery caught fire in a Yale University robotics ...

Donut Lab solid-state battery retest by Finland’s VTT shows capacity rising to 110% at 80C, but weight data is still missing.

In the world of battery startups, the path from promising laboratory formula to a delivered product is fraught with pitfalls.

VTT's second independent test shows Donut Lab's solid-state cell delivered 110% capacity at 80°C and survived 100°C discharge, but key claims remain unproven.

Lithium-ion batteries with liquid electrolytes are more susceptible to extreme heat. If a liquid battery gets too hot, the liquid can vaporize and catch fire — a process called thermal runaway. And at ...

As part of its 'I Donut Believe' campaign, Finnish battery developer Donut Lab has published further independent test results for its disputed solid-state ...

Finnish startup Donut Lab is pushing back against industry skepticism by releasing new independent ...

The AMP Center focuses on mobility and power technologies, including charging infrastructure and power-delivery systems for ...

Donut Lab, a California-based startup developing solid-state battery technology, has drawn intense attention and sharp criticism over claims that its donut-shaped cells can outperform conventional ...

Independent testing shows Donut Lab’s solid-state battery survives extreme heat and retains performance at temperatures up to 100°C.

Independent high-temperature testing suggests the Donut Battery doesn’t just survive extreme heat, it improves efficiency — potentially rewriting the rulebook on EV battery safety and performance.

Donut Lab released the results of the second independent test showing that its solid-state battery can handle extreme heat without affecting its performance ...
