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.

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

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 ...

The Donut Lab solid-state battery was heated to the boiling point of water. Here’s what happened next.

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

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

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 ...

Since announcing earlier this year that it was on the cusp of a major battery breakthrough, Finnish startup Donut Lab has faced a lot of questions, and plenty of skepticism, about its production-ready ...

A research team from the Dalian Institute of Chemical Physics (DICP) under the Chinese Academy of Sciences has announced a significant breakthrough in lithium battery technology, featuring a ...

LFP cells usually last longer than their NMC/NCA counterparts, thanks to a lower nominal voltage. Common wisdom suggests LFP cells can be charged frequently to 100% without experiencing significant ...
