The electrochemically synthesized polypyrrole and lead-lead sulfate is examined as a potential electrodes for battery-type hybrid supercapacitors in acidic solution. The device exhibits battery-type behavior at low discharge rate, e.g. <0.5 A g−1, and supercapacitors-type behavior at a higher discharge rate. Discharge in the specific current range of ∼0.6–2.27 A g−1 based on the active masses, can deliver capacity of 90–72 Ah kg−1, energy of 58–40 Wh kg−1 and power of 40–1350 W kg−1, with the specific capacitance of the cell in the range of 300–250 F g−1. The experimentally obtained values are compared with theoretical.
