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 released its second independent solid-state battery test result Monday. The pouch cell was subjected to extreme temperatures as high as 212 degrees Fahrenheit. It appeared to perform well at ...

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 ...

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

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

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

Rocket Lab (NasdaqCM:RKLB) recently completed a successful hypersonic test mission for the U.S. Defense Innovation Unit using its HASTE launch vehicle. The company also launched advanced silicon solar ...

The mission sent Hypersonix’s DART AE scramjet aircraft on a suborbital hypersonic flight, reaching several times the speed ...

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

Even if you feel healthy, lab tests can reveal early warning signs. Dr. Sydney Le Guyader from Intermountain Health explains ...

For nearly two decades, two-dimensional (2D) semiconductors have been studied as a complement or possible successor to silicon transistors, promising smaller, faster and more energy-efficient ...
