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 ...

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

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

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 ...

Volkswagen's partner Gotion begins real-world vehicle testing of all-solid-state EV batteries designed to deliver 1,000 km range.

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

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

As part of its 'I Donut Believe' campaign, Finnish battery developer Donut Lab has published further independent test results for its disputed solid-state ...

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

Glyph's rugged, handsome Atom EX20 external 3.2x2 USB SSD proved very fast -- but only after I switched to a higher-quality cable.
