摘要
Using hydrazine hydrate (N2H4·H2O) as precipitant, micro-flowers NiWO4 was prepared by co-precipitation and low-temperature heat treatment, and its capacitance was studied. The different amount of N2H4·H2O resulted in two different morphologies of the samples. The electrochemical performance of the sample was tested by CV, GCD, and EIS. The results show that the specific capacitance of the nickel tungstate electrode is 170 F g−1 when the current density is 1 A g−1 in 6 M KOH solution, and the specific capacitance and rate performance of the sample are greatly improved.
