Supercapacitors have many advantages applied in a variety of fields for their larger capacitance,high power density and long cycle life. In general, supercapacitors can be classified into two categories, namely, pseudo-capacitors and double-layer capacito Supercapacitors have many advantages applied in a variety of fields for their larger capacitance,high power density and long cycle life.
