Abstract：

The hydrous Mn-Ni-Co mixcd oxidc (MNCO) clccrodes were clcctrochcrrically deposited by using cyclic voltanuuctry.The potcnial of the film dcposition was cycled bciwccn0.5and 1.5V at the scan ralc of 25mV/s. The compositional and nanostructural properties of MNCO clcetrodes were characlcrized by using scanning clcctron microscopy with cnergy dispeisive spccuoscopy.The capacitivc characteristies of MNCO clcctrode were investingated by cyclic voltanmerty(CV)and constant charge-discharge cycling in the 0.1M Na2SO4 solution. The speeific capacitance valucs of Mn oxide and MNCO electrodes were 139，142 and 168 F/g at 25mV/s，respcctivcly，the discharge time of MNCO electrodes wes smaller than other oxides，indicating the capability of clurgc was poor.The spccific capacitance value of MO elcctrode was degradcd wish 34% and both MNO and MNCO elcctrode were only degraded with 19% after 500-times CY cycles.
