Polyaniline (PANI) as active material of batteries possesses excellent electrochemical reversibility. Itis a promising candidate for a rechargeable battery with a high performance. However, currentcollectors become a manufacturing bottleneck of PANI battery. In this paper, the effects of five currentcollectors: stainless steel (SS), conductive plastics (CP), aluminum foil (AF), lead foil (LF) and carbonfiber (CF) on the stability and electrical properties in the electrolyte (1M ZnClO4/EC+DMC (volumeratio=1:1)) are studied by cyclic voltammetry, electrochemical impedance spectroscopy (EIS),galvanostatic polarization, monitoring of weight and scanning electron microscopy (SEM). Stainlesssteel (SS) and carbon fiber (CF) exhibit higher stability than the others which are corroded byimmersion. But the charge transfer resistance of stainless steel (SS) loaded polyaniline is much higher.Charge-discharge of Zn/polyaniline battery applying carbon fiber (CF) as a current collector showshigh stability, specific capacity and coulombic efficiency. So carbon fiber (CF) is considered to be oneof the best current collectors for PANI secondary batteries in nonaqueous medium. The study providesan academic foundation and application prospect for developing PANI secondary battery.
