Abstract

Poly(o-toluidine) (POT) is electrochemically synthesized on graphite electrode at constant current density of 1.5 mA cm-2 from aqueous electrolyte of 1.0 mol dm-3 H2SO4 and 0.25 mol dm-3 o-toluidine. Electrochemical characterization of POT electrode is performed using cyclic voltammetry, Mot Schottky analysis and galvanostatic measurements at different currents. POT electrode exhibited high energy storage features, with specific energy up to 17.5 Wh kg-1 and specific power up to 3300 W kg-1. Cyclic stability exceeding 90% is obtained over 2000 charge/discharge cycles at 13.1 A g-1 indicating the perspective application of POT electrode as energy storage material.
