Abstract
Graphene is expected to beone of the most promising materials for Li-ion batteries due to its excellent conductivity, ultra-high surface area and flexible sheet-like structure. It is important to control the microscopic structure of graphene to optimize the transmission behavior of electrons and Li ions for better electrochemical performance. Liu’s group developed a metal etching method for controllable synthesis of porous graphene to enhance diffusion of Li ions. Combining with vacuum filtration or hydrothermal self-assembly, porous graphene anode materials with different morphologies, high specific capacity and excellent rate capability and cyclic stability were obtained. In addition, by altering the reaction atmosphere, porous metal oxides with 2D sheet-like morphology were synthesized using graphene oxide as the sacrificial structure-directing template. Employing this reaction route, film-like ZnCo2O4/graphene composite electrode with excellent electrochemical performance was designed and successfully synthesized, and flexible battery based on this film electrode was fabricated.
