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

Finnish technology company Donut Lab has published the results of its third test measuring the properties of its solid-state battery. The test evaluated the ...

Donut Lab battery validation adds a 10-day room-temperature retention figure of 97.7%, while energy density and weight data remain absent.

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 ...

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