| Abstract |
Molybdenum disulfide (MoS2) is regarded as a representative layered two-dimensional (2D) material in energy storage, and attracting considerable attention for energy storage devices. In this work, simple and scalable fabrication of ultrathin few-layer MoS2 nanosheets supported on graphene nanofoam (GNF) is developed by combing a straightforward solvothermal method to synthesize an ultrathin MoS2 and graphene nanofoam made from chemical vapor deposition (CVD). Transfer of MoS2/GNF onto flexible substrate allows a highly efficient fabrication of mSCs with unique flexibility, mechanical stability, and potential application in wearable electronics. The as prepared MoS2/GNF mSC exhibit an outstanding electrochemical performance in terms of high volumetric capacitance and capacitance retention after 10,000 cycles. The MoS2/GNF mSC exhibit simultaneously ultrahigh energy density and power density in a H3PO4 gel polymer electrolyte. |
