Tin based materials including SnO2, SnS2, and Sn, have been considered as one of the most promising anode materials for high energy and power density rechargeable metal (Lithium or Sodium) ion batteries. The main drawback of this material system has been stemming from the large volume changes and accompanying decrease in capacity that occurs during electrochemical cycling. Studies have shown that graphene based composites with reasonable microstructure can efficiently improve the electrochemical properties of the electrode material, making full use of advantages of all the constituents to overcome the defects of single phase. Establishing a reasonable method to realize the effective combination between graphene and other material is the key point on graphene based composites research. The presentation will introduce nanocarbon-templated in situ conversion methods combining the liquid and high-temperature chemical approaches, during which in situ transformation of metal oxide to metal or metal sulfides on the surface of graphene or carbon nanotubes were realized. With this method, a series of graphene based composites including the graphene confined tin nanoparticles/nanosheets, graphene / tin@carbon nanocables composite and graphene / tin sulfide composite have been developed with excellent electrochemical performance for energy storage.
