演讲题目：The Progress in Applications of Graphene Materials in Li-ion Batteries
内容摘要
This presentation will introduce the progress of the application of graphene materials in Li-ion batteries achieved recently in our group. Based on excellent electrical conductivity and two dimensional nanostructure of graphene, a series of graphene modified electrode materials, including graphene/LiFePO4, graphene/TiO2 and graphene/Si, with outstanding electrochemical performances have been prepared by rational structural design. Highly conductive graphene nanosheets can also be used as a novel conductive additive to enormously reduce the internal resistance of the batteries and increase the compact density of the electrode, result in enhanced energy density, better rate capability and cyclic stability. Using graphene coated Al foil as the current collector can effectively reduce the contact resistance between active materials and the current collector, and also increase their adhesion force, giving rise to excellent high-rate performance and longer cycle life of the battery. Our research evidently shows that graphene can play important roles in high-performance Li-ion batteries.
