Graphene possesses distinct properties such as large specific surface area, excellent electrical conductivity high chemical stability, and so on. These superiorities make it possible to apply in next-generation batteries with high energy density and high power density. In addition, Li-ion batteries can be enhanced by adding graphene in the term of lengthening life-time, shortening charging times and reducing battery temperature, etc. Consequently, so-called ‘Super Batteries’ developed by graphene will possibly bring brand-new revolution to industry of battery and electric vehicle.  However, from the present laboratory research results, both capacity and cycle life of the graphene batteries are poor, far from the theoretical speculation. Therefore, is it possible to design and develop new-type graphene electrode materials with high energy density and high power density? Will the technological revolution of graphene battery realize? This talk presents several research strategies about graphene-based electrode materials, and introduces our exploration works for high performance graphene-based electrode materials.
