Furthermore, due to the over-capacity design of the anode, the phenomenon of lithium plating on a surface of the anode can also be prevented when a battery cell is at a high cut-off voltage, thereby greatly improving the safety performance of the battery. In addition, the over-capacity anode also ensures the cycle life of the lithium-ion supercapacitor under high-rate charging and discharging.
