Researchers from Osaka Metropolitan University introduced new 300°C heat-tolerant, high-capacity lithium supercapacitor created with solid electrolytes borrowed from all-solid-state batteries. Capacitors are energy storage devices, consisting of two electrodes and an electrolyte, that are capable of rapid charging and discharging because of charge adsorption and desorption properties at the electrode-electrolyte interface. Because capacitors’ energy storage Read the original post Researchers Introduced 300°C High Temperature...
