β-NiMoO₄nanowire arrays grown on carbon cloth for 3D solid asymmetry supercapacitors

Abstract

A β-NiMoO₄NW supercapacitor lights one LED for 260 s and delivers a large specific capacitance (414.7 F g⁻¹at 0.25 A g⁻¹), high energy density (36.86 W h kg⁻¹), a maximum power density of 1100 W kg⁻¹and 65.96% capacity retention after 6000 cycles.
