Researchers at Empa and EPFL have reported a stretchable, silicone-based solid electrolyte aimed at addressing a persistent problem in next-generation lithium-metal batteries: the tendency of rigid ...
VTT testing says Donut Lab’s “solid-state” battery likely matches lithium-ion; energy density measured at 298 Wh/kg, claims ...
Donut Lab, a Finnish solid-state battery maker, claims its cells retained 97.7% of their charge after sitting idle for 10 days, a figure that, if independently confirmed, would represent a sharp ...
Solid-state sodium batteries use sodium, a more abundant and accessible resource compared to lithium. Sodium is primarily derived from sodium chloride, which is abundant in seawater and readily ...
