beta-NiMoO4 nanowire arrays grown on carbon cloth for 3D solid asymmetry supercapacitors

Based on beta-NiMoO4 nanowire (NW) arrays grown on carbon cloth as the electrode materials, a 3D solid asymmetrical supercapacitor has been fabricated. The produced beta-NiMoO4 NW arrays on carbon cloth compared to the power of NiMoO4 nanowires deposited directively on carbon cloth can increase the efficiency of nanomaterials participating in reactions. The cone-shaped NW arrays have a high specific surface area (99 m(2) g(-1)), which can provide more electroactive sites for Li+ and enhance conductivity through providing short transport and diffusion paths for both ions and electrons. And the cylindrical supercapacitor can allow more beta-NiMoO4 NW arrays to saturate with electrolyte to enhance the properties of the supercapacitor. Furthermore, the electrode has a highest energy density of 36.86 W h kg(-1), a maximum power density of 1100 W kg(-1), and a large capacitance of 414.7 F g(-1) at a current density of 0.25 A g(-1), all of which demonstrate excellent behavior. And the capacitance of the supercapacitor reached 65.96% of the initial capacitance over 6000 cycles. All of these results indicated that the beta-NiMoO4 NW arrays grown on carbon cloth could be a promising candidate for high performance supercapacitors.
