Characteristics of aqueous polycarbazole batteries

Abstract

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(ClO4)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. © 1999 John Wiley & Sons, Inc.
