Review of Graphene in Cathode Materials for Lithium-Ion Batteries

Abstract

With the development and progress of science and technology, energy is becoming more and more important. One of the most efficient energy sources is lithium-ion batteries. Graphene is used to improve the rate performance and stability of lithium-ion batteries because of its high surface area ratio, stable chemical properties, and fine electrical and thermal conductivity. In this paper, several common cathode materials of lithium-ion batteries, the preparation methods of graphene, and the combination of graphene and polyanion are reviewed and the research direction of graphene application in cathode materials of lithium-ion batteries is prospected.
