Mesoporous NiMoO 4 nanorod electrode materials for flexible and asymmetric energy storage devices.

Recently, ternary metal oxides as cathode materials have been the focus of research into supercapacitors owing to their high power density and cost-efficient features. The development of excellent electrode materials is the key to improving supercapacitor total performance. Herein, we report several kinds of NiMoO 4 nanostructures grown on nickel foam using a simple hydrothermal strategy. The assembled hybrid devices show an energy density of 35.9 W h kg -1 at a power density of 2708 W kg -1 . After repeated charging and discharging cycling and bending tests, they show excellent durability performance and mechanical stability performance.
