Abstract:Combining with the current hotspot of using the special two-dimensional structure, excellent physical and chemical properties of graphene materials, the low energy density and poor cycle performance of lithium ion batteries were improved. Based on the recent research progress of graphene and its composite materials in lithium ion battery cathode, anode materials, the defects and deficiencies of the existing electrode material were pointed. The importance of the structure and function regulation of graphene composites as lithium ion batteries electrode was discussed, the current challenge and future perspectives in the applications of graphene materials were also reviewed.
