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

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 ...

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

Donut Lab revealed the first independent test showing that its solid-state battery is capable of 11C charging, although it still has to prove other claims ...

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 ...

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 ...

Additional tests of a Volvo C40 Recharge, performed by Bjørn Nyland, reveal that the available battery capacity might be higher than initially anticipated. During the near full discharge tests (from ...

The global capacity of utility-scale batteries increased more than 12-fold between 2020 and 2024 to 124 GW, while average battery costs fell 58% over the period, according to the Electricity 2026 ...

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 ...
