Abstract

Designing specific structured electrode materials is essential for efficient electrochemical energy storage. Graphene owns unique 2D structure and possesses excellent electrical conductivity, ultrahigh specific surface areas, as well as colloidal self-assembling behavior, which make it an ideal candidate for constructing hybrid electrode materials with remarkably enhanced electrochemical performances. This article reviews the recent research progress made on various 3D graphene-based electrode materials and their applications in electrochemical energy storage such as Li-ion and Li-S batteries. Based on the recent works made by our group, we highlight the principles of designing graphene-based materials, and discuss various advanced structures of graphene-based electrodes. Furthermore, future research directions for the development of novel and more efficient graphene-based electrode materials are proposed.
