▎ 摘　　要

The graphene supported SnO2 nanoparticles (SnO2/graphene nanocomposites) were synthesized by a facile microwave-assisted polyol reduction method. The Na-storage performance of the as-prepared SnO2/graphene nanocomposites was evaluated as an anode material for sodium-ion batteries (SIBs), presenting a high initial reversible capacity of 220 mA h g(-1) at a current density of 0.1 A g(-1) and an acceptable rate capability. This work provides an effective approach on synthesizing the SnO(2/)graphene nanocomposites and a potential anode material for SIBs. (C)) 2015 Elsevier B.V. All rights reserved.
