  ABSTRACT: Nickel oxide/copper oxide composites are prepared. Then the composites were transferred into autoclave and thermal sinter under different temperature and different time. As-prepared composites were analyzed by XRD, and it was concluded that with the increase of hydrothermal time, content of NiO and Ni0.75Cu0.25O increases, but particles become smaller; it would improve the electrochemical activity. By SEM images directed lower crystallinity of composites, deeper porosity and rougher surface would have better electrochemical activity. The electrochemical performance was investigated by cyclic voltametry, AC impedance and galvanostatic charge-discharge. All results show that under the condition of 150°C 30 h, the electrochemical performance is the best. The specific capacitance was 225.67 F·g-1 at the charge-discharge current of 1 A·g-1.
