摘  要：近年来，随着经济和科技迅速发展，人们对储能器件的要求越来越高

Abstract: In recent years, with the rapid development of economy and science and technology, people have increasingly higher requirements for energy storage devices. Commonly used anode materials for energy storage devices cannot meet the requirements of energy density, cycle life, and power density, so it is urgent to look for excellent electrochemical anode materials. Graphene is widely used in the field of energy storage because of its unique two-dimensional microstructure, large specific surface area, and good electrical and thermal conductivity. The graphene-based porous material has a higher specific surface area than graphene, and has a three-dimensional network structure that interpenetrates, which can provide a multi-dimensional electron transmission path, and at the same time increase the contact area with the electrolyte, thereby achieving electron Fast transmission of ions. In this paper, a graphene-based porous material was prepared by chemical activation method and applied to supercapacitors. Preliminary results show that graphene-based porous materials have higher specific capacity, good rate performance and stable cycle performance.

Graphene is widely used in the field of energy storage because of its unique two-dimensional microstructure, large specific surface area and good conductivity and thermal conductivity. The graphene based porous material has a higher specific surface area than graphene, and has a three-dimensional network structure connected with each other, which can provide multi-dimensional electronic transmission channels, and increase the contact area with the electrolyte, so as to realize the rapid transmission of electrons and ions at a high rate. In this paper, graphene based porous materials were prepared by chemical activation method and applied to supercapacitors. The preliminary results show that graphene based porous materials have high specific capacity, good rate performance and stable cycle performance.
