英文摘要： To solve the problems of low capacity and high self-discharge of supercapacitor, this program poposes a design of a new composite cathode material of metallic oxide (MOX) with special microstructure and porous starch-based graphene-like with high specific surface area and conductivity used for supercapacitor. The composite cathode material with high density, high specific capacity and low self-discharge rate used for supercapacitor takes full advantages of porous graphene-like with excellent conductivity, capacitance, pores and framework. Research has focused on the scientific problems of preparation of MOX/starch-based porous graphene-like cathode material, reaction of composite capacitance and self-discharge progress of supercapacitor based on MOX/starch-based porous graphene-like, etc. New research techniques, such as SECM, are explored to investigate the cathode rections of double-layer and pseudo capacitances and essence of self-discharge reaction. This program will get advanced preparation method of MOX/starch-based porous graphene-like composite cathode material to provide theoretical basis for application of supercapacitor in the aspect of new energy storage.
