Molybdenum disulfide is a promising candidate for the anode material in lithium-ion batteries due to its high theoretical specific capacity. However, volume change during cycling causes poor cycling stability and rate performance, and improving cycle life is a major research challenge. Herein, we present a strategy by fabricating phosphorus-doped graphene-wrapped molybdenum disulfide hollow spheres to improve the electrochemical performance of molybdenum disulfide in lithium storage. It is demonstrated that the obtained composite shows excellent electrochemical performance as anode material for lithium-ion batteries. The composite exhibits the high specific capacity of similar to 1097 mA h g(-1) at a current of 100 mA g(-1), as well as excellent cycling stability and high-rate capability. The unique hollow structure combined with phosphorus-doped graphene wrapping definitely contributes to this versatile electrochemical performance.
