The specs it's put forward are extraordinary: 400 watt-hours of energy density (roughly double today's lithium-ion cells), a ...

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

Volkswagen’s partner, Gotion High Tech, has begun testing all-solid-state EV batteries with a CLTC range of 1,000 km (620 ...

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 ...

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

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

During testing, the solid-state cell sustained an 11C charging rate. The battery reached 80 percent charge in 4.5 minutes and ...

VTT testing says Donut Lab’s “solid-state” battery likely matches lithium-ion; energy density measured at 298 Wh/kg, claims ...

The big reveal at CES of a production-ready solid-state battery needs backup.

This week already brought us a camper loaded with solid-state battery power, and now we have a luxury EV putting its own solidified energy storage to work. BMW is road-testing solid-state batteries in ...

The BMW Group is bringing large-format, pure ASSB cells from Solid Power to its test vehicle, a BMW i7, which is being operated in the Munich area. The potential benefits of ASSB technology: higher ...

BMW is testing solid-state battery cells developed by Solid Power in the i7 sedan. Solid-state compositions promise lighter weight, greater energy density and thermal safety, and longer ranges for EVs ...
