英文摘要	A novel self-supported electrode of nickel vanadate and nickel oxide nanohybrid on nickel foam with excellent pseudocapacitive properties was synthesized using a combination of a hydrothermal strategy and subsequent annealing treatment. The porous nanostructure not only provides a larger surface area for faradic reactions, but also allows the rapid transportation of electrolyte ions for improving rate capability. The electrode demonstrates outstanding capacitance, satisfying rate capability and good cycling stability, showing the coupling effects of nickel vanadate and nickel oxide. In this case, the electrode has an energy density of 46 W h kg(-1) at a power density of 101 W kg(-1), demonstrating the importance and great potential of nickel vanadate in the development of energy storage systems.
