Sn nanoparticles supported on nitrogen-doped graphene oxide (GO) were successfully synthesized using a liquid-phase reduction method, which circumvented the agglomeration of low-melting-point tin particles during the pyrolysis process. The results indicate that the tin particles anchored on the GO surface have a significant effect on stress balancing of the entire composite material in the process of charging and discharging; the reduction by ethylenediamine on the reduced GO (rGO) causes extensive wrinkling, which can relieve the pressure resulted from the volumetric expansion of tin nanoparticles during cycling. After 300 cycles, the resulting material achieves a repeatable capacity of 1739 mAh g−1 under an ampere density of 500 mA g−1.
