One method to improve efficiently polyaniline's electrochemical properties is the comixing of polyaniline with disulfide disulfonic acid. When doped with disulfidedisulfonic acid, polyaniline's electrochemical activity is greatly improved. The bondage-S-S-of the dopant coparticipates oxidation-reduction reaction with polyaniline in the same area, thus polyaniline's capacity and charge-discharge cyclibility are improved.

Key words: Polyaniline, Disulfidedisulfonic acid, Electrochemical, Secondary battery
