CoSnO3/G nanohybrid has been synthesized by thermal annealing of CoSn(OH)(6)/G, prepared by a facile in situ solvothermal route using CoSO4, K2SnO3 and GO as precursors and has been investigated as a promising high-performance anode material for Li-ion batteries. The CoSnO3 nanocrystals are uniformly dispersed and immobilized by graphene nanosheets reduced from GO. The CoSnO3/G composite exhibits superior cycling stability and rate capability compared to bare CoSnO3. The improvement in electrochemical performance can be attributed to the combined conducting, confining and dispersing effects of graphene for the CoSnO3 nanocrystals. (C) 2014 Elsevier Ltd.
