Although molybdenum disulfide (MoS2) has a higher theoretical capacity than graphite as an anode material for lithium-ion batteries, its intrinsically poor electrical and ionic conductivity decrease its rate properties and lithium-storage capacity. In this work, we prepared a MoS2/reduced porous graphene oxide (rPGO) composite by the solvothermal method to complement the conductivity and to improve the lithium-storage properties of MoS2. PGO was synthesized by a convenient, low-costing, and mass-producible nitric acid treatment method. Owing to its large surface area and porous structure, the MoS2/rPGO sample exhibited improved capacity and cyclic stability over other MoS2/reduced graphene oxide (rGO) and MoS2 nanoparticle samples. After 100 cycles, the MoS2/rPGO electrode showed an improved capacity of 932 mAhg(-1), whereas the capacity of the MoS2/rGO electrode was 395 mAhg(-1) at a current density of 200 mAg(-1).
