Something quietly extraordinary is happening inside research labs, factory pilot lines, and test vehicles right now. The ...

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.

Scientists at Nankai University in Tianjin, China, claimed to have built a solid-state battery that can power electric ...

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.

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

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 released independent testing of its new solid-state battery, which can charge to 80 percent in just five minutes.

When a company claims to have created what’s essentially the holy grail of batteries, there are bound to be some questions.

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 ...

Electric vehicles and grid storage systems depend heavily on lithium and other costly metals.
