Popis:	The characteristics of electrochemically prepared polycarbazole (PCARB) as the cathode active material for secondary batteries are studied in aqueous electrolytes. The cell of the type Zn/Zn(ClO 4 ) 2 /PCARB has a specific capacity of 30 Ah/kg and an energy density of 46 Wh/kg. The coulombic efficiency is about 80-90% and is dependent on the thickness of PCARB films. Cole-Cole plots for PCARB electrodes by impedance measurements have been obtained at different oxidation potentials as a function of doping.
