英文摘要: In view of the low energy density of supercapacitor, this project intends to control the restacking content of graphene sheets by uniting the solvation effects, the corrugation of graphene sheets and the hybridization of Ni(OH)2-Co(OH)2 double nanoparticles. The ternary hydrogel material with porous network structure will be designed using corrugated graphene sheets as main construction unit decorated with double hybrid nanoparticles. It is expected that the ternary structure material can make full use of good cycle and conductive performance of graphene, and high specific capacity of hybrid materials. The influence of assembly behavior of graphene hydrogel, microstructure and synergistic effect of hybrid particles on the electrochemical properties will be investigated. Studying the interaction between components of the hybrid system to explore reaction mechanisms, providing a new pathway for the development of electrode material of supercapacitor with high energy density.
