We have demonstrated a facile approach for synthesis of polypyrrole coated yttria partially stabilized zirconia nanocomposites by in--situ synthesis method. The properties of nanocomposite were studied and compared with those of polypyrrole and 8% YSZ. The electrochemical properties were recognized by cyclic voltammetry, charge-discharge and electrochemical impedance spectroscopy. The SEM of YSZ/PPy nanocomposite showed globular and porous surface morphology. In the present work, we reveal the YSZ/PPy nanocomposite as novel electrode material for supercapacitor. The supercapacitive performance of YSZ/PPy electrode was studied in an aqueous 0.1 N H2SO4 electrolyte solution. The highest specific capacitance (Cs) for YSZ/PPy electrode observed to be 640 Fg-1. The specific energy (Es), specific power (Ps) and coulomb efficiency (η%) are observed to be 12.8 Whkg-1, 51 kWkg-1 and 98% respectively. This electrode shows the outstanding electrochemical stability for more than 1000 continuous charging--discharging cycles. These notable parameters of YSZ/PPy composite opens up a new avenue for the study to explore this composite as an efficient electrode material.
