Enhanced cyclic performance is a great challenge tor the application of tin dioxide-based anode in lithium-ion batteries.In this study,a facile strategy using one-step heat treatment at low temperature(390 ℃)is developed to synthesize SnO2 nanoparticles anchored on chlorinated graphene as binder-free electrodes that exhibit a long cycling life up to 400 cycles with a discharge capacity of 1008 mAh g-1.
