Chinese researchers unveil 451.5 Wh/kg solid-state battery with 3-minute charging capability

The research focused on polymer electrolytes based on PVDF, which has been widely studied for solid-state batteries due to its oxidation stability and ionic conductivity

Researchers at the Chinese Academy of Sciences have reported the development of a high-energy solid-state lithium-metal battery that has achieved an energy density of 451.5 watt-hours/kilogram while maintaining stable cycling under ultrafast-charging conditions at a 20C rate, which is equivalent to about 3-minute charge and discharge cycles.
