VTT's second independent test shows Donut Lab's solid-state cell delivered 110% capacity at 80°C and survived 100°C discharge ...
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 battery validation adds a 10-day room-temperature retention figure of 97.7%, while energy density and weight data remain absent.
