Abstract	To improve the electrochemical performance of the CoS2cathode, a CoS2/reduced graphene oxide/multiwall carbon nanotubes (CoS2/rGO/MWCNTs) composite was synthesized. The mixture showed a high initial discharge capacity of 1562.6 mA h g−1and a capacity of 884.9 mA h g−1after 100 cycles at the current density of 100 mA g−1which were higher than that of CoS2/rGO and CoS2/MWCNTs. The improved electrochemical performances were attributed to rGO and MWCNTs which ensured fast Li+and electronic transport in the composite. What's more, rGO sheets wrapping tightly outside CoS2/MWCNTs in CoS2/rGO/MWCNTs composite accommodated volume expansion of CoS2and prevented CoS2gathering. © 2017
