摘要

Reduced graphene oxide (RGO) decorated ternary Cu2SnS3 composite has been synthesized by one-step facile hydrothermal route. The formation of Cu2SnS3 nanoparticles and reduction of graphene oxide occur at the same time during the hydrothermal process. The Cu2SnS3 nanoparticles with a size of 5-10 nm are uniformly distributed on the RGO, which prevents effectively the agglomeration of Cu2SnS3 nanoparticles. The Cu2SnS3/RGO composite electrode exhibits an initial reversible capacity of 704 mAh g(-1) and 560 mAh g(-1) after 100 cycles. Such excellent electrochemical performance can be attributed to the presence of RGO, which improves the electronic conductivity and prevents the agglomeration of Cu2SnS3 nanoparticles. In addition, the Cu induced by the Cu2SnS3 reaction with lithium ions during the discharge process can increase the electronic conductivity. (C) 2015 Elsevier B.V. All rights reserved.
