Nano Reticular MoS 2 is prepared in the hydrothermal method. By means of hydrothermal method, the cathode material of composite electrode of MoS 2 /RuO 2 is prepared. For all kinds of prepared samples, physical characterization analysis, such as SEM and XRD, and electrochemistry tests, such as cyclic voltammetry, alternating-current impedance and galvanostatic charge-discharge, are conducted. The test results show that the addition of a small amount of molybdenum disulfide improves the specific capacity of composite electrode, lowers alternating equivalent impedance and improves conservation ratio of specific capacity. When the doping content of molybdenum disulfide is 25%, specific capacity of binary composite electrode can reach 413 F/g and equivalent alternating-current impedance is equal to 0.665Ω. By means of 800 charge-discharge cycles, specific capacity still remains around 87%.
