Self‐doped poly(indole‐5‐carboxylic acid) (P5CO 2 H) is electrodeposited from acetonitrile containing 0.1 M LiClO 4 as electrolyte and characterized by UV–vis, IR, cyclic voltammetry, and scanning electron microscopy techniques. The polymer is evaluated as a cathode active material together with a Zn anode in rechargeable cells containing 1 M ZnSO 4 at pH 5. The cell shows an open circuit voltage of 1.36 V and a specific capacity of 67 Ah kg −1 . The ac impedance study shows a predominant diffusion mechanism. © 2005 Wiley Periodicals, Inc.
