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

Roughly three months ago, electric motorcycle startup Verge Motorcycles announced something huge, claiming its updated Verge ...

The individual cell charged in about five minutes in an independent test. But can it do that at the pack level over many charging sessions?

The startup's third test evaluates whether its solid-state battery is actually a supercapacitor. Here's what the results say.

Donut Lab, a venture-backed startup operating largely in stealth mode, has presented a solid-state battery prototype that the ...

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

Donut Lab battery validation adds a 10-day room-temperature retention figure of 97.7%, while energy density and weight data remain absent.

The race to revolutionize the science of electric vehicles (EVs) is heating up. Stream Los Angeles News for free, 24/7, wherever you are. Often touted as the "holy grail" of sustainable driving, solid ...

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.

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 ...

Its solid-state batteries are already showing promise with real-world tests delivering over 745 miles of range on a single charge. Now, Factorial Energy is going public as it aims to bring the ...
