HYDROTHERMAL CARBONIZATION OF CHITOSAN FOR HIGH-PERFORMANCE SUPERCAPACITOR ELECTRODE MATERIALS

摘要

Supercapacitors, which are high-performance energy- storage and delivery components that retain electrical charge through electrochemical pseudocapacitance or by an electrostatic double-layer, have many applications in power systems and energy devices. A number of materials such as activated porous carbon and transition metal oxides have been used to assemble high-performance supercapacitors.
