摘　　要：本文对目前石墨烯在电化学储能过程中理论计算的研究进行系统整理,从石墨烯材料电子结构特征出发,对其在超级电容器、锂离子电池和氧还原过程中石墨烯起的作用进行综述,详细讨论了石墨烯在以上不同电化学环境中与物质的相互作用机制,为新型石墨烯基电化学储能器件的研究提供理论基础和研究思路。Recent progress in the theoretical research on the band structures of perfect,defective and doped graphenes is reviewed. The relationship between the quantum capacitance of graphenes in supercapacitors and their band structures is analyzed.Electronic interactions and the diffusion behavior of Li ionsin different graphenestructures in lithium ion batteries are summarized.The role of different structures in the oxygen reduction reaction in the lithium-air battery is elaborated. This theoretical research lays a solid foundation for newideas for novel graphene-based energy storage devices.
