Abstract

To improve the conductivity of pure polyaniline (PANI), compact scale-like PANI secondary doped with lithium chloride (LPANI) was prepared after the in situ synthesis of PANI powder using the constant current method and 4,4’-diaminobiphenyl (DABP) as an additive in hydrochloric acid (HCl). The dense morphology of obtained LPANI was found to promot to the charge transfer in the PANI chains and intermolecularly. The oxidation peak currents of LPANI with DABP additive were nearly three times higher than those of the LPANI and much higher than those of in situ doped PANI with HCl without additive. The application of LPANI in composite film batteries was also examined. Both the LiCl-PANI/TiO2/C/DABP composite (LPTCD) cathode and Zn/ZnO/MgO/CMC-Na composite (ZZMCN) anode were prepared by evenly coating at controlled thicknesses of 0.20 mm and 0.04 mm, respectively. A coated Zn composite//coated LPANI composite battery was designed, with an open voltage of approximately 1.5 V in ZnCl2+LiCl electrolyte solution. The battery charge/discharge cycle performance was determined between 0.7 V and 1.7 V. The discharge capacity of the cathode reached 131.4 mAh·g-1 at a current density of 2 mA·cm-2. During 35 charge/discharge cycles, the average decrease in the discharge capacity of each cycle was 0.07%, indicating that the cycle performance and stability of the battery could contribute to applications that replace traditional lead-acid batteries.
