The NiWO4 powder was prepared by combining the hydrothermal method with calcination. Several studies have demonstrated that NiWO4/graphene oxide composite can enhance electrochemical performance of material. However, no investigated use material as cathode in zinc-ion batteries. successful preparation is verified various characterization techniques. composite, which meant to be a material, fabricated into electrode sheets and incorporated CR2025 coin cells for assessment. experimental results indicate exhibits high charge–discharge specific capacity rates. At current density 0.1 A g−1, it has 490.2 mA h g−1. Even after 2000 cycles at 1 remains constant 75.2%. Through calculations, found charge storage mainly contributed pseudocapacitance.
