The influence of current density on charge/discharge characteristics of polyaniline electrode

Abstract

Polyaniline (PANI) was electrochemically synthesized on graphite electrode galvanostaticaly from aqueous solution of 0.25 mol dm-3 aniline and 0.5 mol dm-3 p-toluenesulfonic acid. Charge capacity available for the exchange and the total theoretical weight of polyaniline polymerized on graphite electrode was determined. Characterization polianiline electrode was performed by cyclic voltametry in 0.5 mol dm-3 HCl. Based on the PANI electrodes behavior during the cyclization, was tested the possibility of practical application of polyaniline doped p-toluenesulfonic acid as the anode material of secondary electrochemical power sources.
