Lithium ion supercapacitor is a high energy density supercapacitor battery, combining the advantages of fast charging and discharging and long cycle life of supercapacitor, suitable for long time power supply applications.

It is a new type of energy storage device based on the "parallel connection" between the double layer capacitor and the lithium ion battery. The two poles are separated by a diaphragm, the electrolyte is filled in the internal space of the unit, and the aluminum case is sealed with a rubber plug.
