Carbon Cloth Modified with Metal-Organic Framework Derived CC@CoMoO4-Co(OH)2 Nanosheets Array as a Flexible Energy-Storage Material

Due to the urgent demand for portable electronics, enormous research efforts are devoted for the development of flexible, wearable and lightweight supercapacitors. Herein, we report a cost-effective chemical liquid process followed with a refluxing route to grow CC@CoMoO4-Co(OH)(2) nanosheets with Co-based MOF as precursor. The resulting CC@CoMoO4-Co(OH)(2)-4 electrode delivers a significantly enhanced specific capacitance of 2028 F g(-)1 at 1 A g(-1) and capacitance of 1581.8 F g(-1) at 20 A g(-1). Furthermore, the flexible all-solid-state asymmetric supercapacitor (CC@CoMoO4-Co(OH)(2)//AC) is assembled, displays a high energy density of 61 Wh kg(-1) at power density of 800 W kg(-1), with an excellent cycle stability. These exceptional electrochemical performances could be ascribed to the unique structure and multi-metal ion combination contributes to the ideal synergistic effects, which also signify that the potential application of CC@CoMoO4-Co(OH)(2) nansheets in high-performance supercapacitors.
