Graphene‐Based Materials for Lithium/Sodium‐Ion Batteries

Various new anode materials, including metal, transition metal oxides, and transitional metal sulfides have developed to meet the increasing demands on safety, energy density, and environmental protection of lithium/sodium-ion batteries. However, their performances were limited by poor electrical conductivity or significant structural damage. To address this issue, graphene architectures have been widely used as a matrix to support active materials due to their high electrical conductivity, large surface area, high flexibility, and robust structural stability. Especially, templated fabrication of graphene composites shows porous structure, which is beneficial to electrolyte diffusion, volume accommodation, and reaction kinetics. In this review, the recent advances of templated fabrication active materials with graphene matrix for lithium/sodium-ion batteries are summarized. In addition, the related challenges are discussed and the outlook is also given.
