Sb-SnO2/MMT/PPy ternary composites were prepared by means of a two-step method including the synthesis of well dispersed Sb-SnO2/MMT and the in-situ chemical oxidative polymerization of Pyrrole. Morphologies and microstructures of the resulting product were characterized by X- ray diffraction (XRD)、Transmission electron microscopy (TEM)、Differential thermal analysis (TG-DTA) and BET．Electrochemical properties of the ternary composites as electrode were investigated by cyclic voltammogram (CV), galvanostatic charge/discharge tests and electrochemical impedance techniques. The results show that the volume resistivity of ternary composites could reach to 2.7 Ω穋m when the covering ratio of polypyrrole was 20%. In addition, it exhibits a maximum specific capacitance of 83.1 F/g, which is greater than the specific capacitance of Sb-SnO2 / MMT binary cornposites．The positive synergy effect between the three components might enhance the capacitive performance．
