2D MoS2 has a significant capacity decay due to the stack of layers during the charge/discharge process, which has seriously restricted its practical application in lithium-ion batteries. Herein, a simple preform-in situ process to fabricate vertically grown MoS2 nanosheets with 8-12 layers anchored on reduced graphene oxide (rGO) flexible supports is presented. As an anode in MoS2/rGO//Li half-cell, the MoS2/rGO electrode shows a high initial coulomb efficiency (84.1%) and excellent capacity retention (84.7% after 100 cycles) at a current density of 100 mA g(-1). Moreover, the MoS2/rGO electrode keeps capacity as high as 786 mAh g(-1) after 1000 cycles with minimum degradation of 54 mu Ah g(-1) cycle(-1) after being further tested at a high current density of 1000 mA g(-1). When evaluated in a MoS2/rGO//LiCoO2 full-cell, it delivers an initial charge capacity of 153 mAh g(-1) at a current density of 100 mA g(-1) and achieves an energy density of 208 Wh kg(-1) under the power density of 220 W kg(-1).
