Electrochemical synthesis and characterization of poly(o-toluidine) as high energy storage material
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.
