Materials science has evolved over the past decades.However,most of research on electrode for energy storage has been focused on active material itself.It is clear that investigating isolated active materials is no longer sufficient to solve all kinds of technological challenges for the development of modern battery infrastructure.Considerable amounts of attentions should be paid on the entire electrode system where studying the interface between individual components within the system is of paramount importance.We present a system-level strategy of designing RGO/SnO2 composites based anode electrode aims at enhancing the energy-storage performance of RGO/SnO2-based materials,especially their cyclic performance.
