China develops lithium-metal battery delivering energy density of 447Wh/kg at -40°F
SMRTR summary
Chinese researchers from the Dalian Institute of Chemical Physics have developed a lithium-metal battery that delivers 447Wh/kg at -40°F, making it suitable for extreme cold environments. It achieves over 750Wh/kg at room temperature under low discharge rates and can surge to 10C output for short bursts. With a self-discharge rate below 1% annually, it targets drones, spacecraft, and rescue equipment.
