1. Energy density; Since the density of solid is higher than that of liquid, if the same volume of solid electrolyte is used to replace the lithium battery electrolyte, the weight of the battery will increase, resulting in a decrease in the energy density (wh/kg) of the battery calculated by weight. The energy density of subsequent solid-state batteries will be significantly improved due to the us...
