▎ 摘　　要

Self-assembled nano-honeycomb WS2 modified by graphene doping were prepared by improved one step hydrothermal method. In this hybrid structure, graphene plays a key role of transferring the morphology from the nanowire microporous spheres to graphene-supported nano-honeycomb plane structure, which has the larger the specific surface area and higher conductivity. This anode delivers the superb electrochemical performances of lithium/sodium ion batteries with high specific charge capacity (953.1/522.3 mAh.g(-1) at 0.1 A.g(-1)), long cycling life (more than 350/200 cycles at 1 A.g(-1)), and high charge/discharge rates (up to 10/5 A.g(-1)). This nano-honeycomb structure WS2 composite anode with facile hydrothermal process, as well as superb electrochemical performances, makes it attractive for the potential applications in lithium/sodium ion batteries.
