Porous carbon electrodes with battery-capacitive storage features for high performance Li-ion capacitors

High-defect mesopore-dominant porous carbon has been prepared via direct carbonization of sheep bone. The high defect density and unique porosity endow this carbon electrode with battery-capacitive storage features, which can be used both as high performance anode and cathode for LIC. The assembled LIC exhibits integrated high energy and power densities, as well as superior long cycling performance.201
