▎ 摘　　要

A novel porous manganese sulfide/graphene composite was prepared by a simple in situ solvothermal approach. These mesoporous manganese sulfide sub-microspheres with an average diameter of 700 nm were anchored homogeneously onto graphene nanosheets. Such a special microstructure not only effectively alleviates the mechanical strain of the electrode upon lithiation/delithiation, but it also improves contact be-tween the electrode materials and the electrolyte. As a result, the composite exhibits a high Li-ion storage capacity and excellent cycling stability as an anode material for lithium-ion batteries. At a current of 50 mAhg(-1), the material delivers a reversible capacity up to 1231 mAhg(-1); at a current density of 0.2 Ag-1, the material still retains a reversible capacity of 735 mAhg(-1) after 300 cycles.
