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

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

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 ...

Power outages have become increasingly common, and longer in duration, due to extreme weather and temperature events. Behind-the-meter (BTM) batteries are proving their worth, as they have become more ...

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

Independent high-temperature testing suggests the Donut Battery doesn’t just survive extreme heat, it improves efficiency — ...

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 ...

Batteries lose capacity over time. The process can be slowed down, but it’s inevitable, so after a few years, your EV won’t provide quite as much range as when it was new. The battery will lose about ...

It is an exciting time in the automotive industry with the development and evolution of new technologies for electric vehicles (EVs). Specifically, battery technology is the key driving force for ...
