We incorporated tin oxide nanostructures into the graphene nanosheet matrix and observed that the phase of tin oxide varies with the morphology. The highest discharge capacity and coulumbic efficiency were obtained for SnO phase of nanoplates morphology. Platelet morphology of tin oxide shows more reversible capacity than the nanoparticle (SnO2 phase) tin oxide. The first discharge capacity obtained for SnO@GNS is 1393 and 950 mAh/g for SnO2@GNS electrode at a current density of 23μA/cm2. A stable capacity of about 1022 and 715 mAh/g was achieved at a current rate of 23μA/cm2 after 40 cycles for SnO@GNS and SnO2@GNS anodes, respectively.
