Title

EFFECT OF PANI/GRAPHITE COMPOSITE ON THE ZN-PANI RECHARGEABLE BATTERY PERFORMANCES

Pages

  5-16

Abstract

 Polyaniline (PANI) is one of the most promising candidates for industrial application of conducting polymers. Due to its reversible electrochemical response during anodic oxidation and cathodic reduction, it is used as secondary batteries active material. In recent years, we see permanent efforts to improve performance of PANI batteries. So, many researches have been carried out for the improvement of its performance. In this work, PANI and PANI/G COMPOSITE were chemically synthesized at 5°C. The characterizations were done by FTIR, Raman, BET, and SEM. Then PANI and PANI/G COMPOSITE used as positive active material for PANI-Zn aqueous RECHARGEABLE BATTERY. The prototype AA batteries were constructed and tested by constant current charge/discharge method between 1700 to 400 mV by 125 mAg-1 current density. It was found that PANI and graphite interaction was increased by COMPOSITE formation between PANI and graphite while its surface area reduced compare to PANI. Then the PANI-G blend and COMPOSITE were evaluated as battery cathode active material containing 5.0M ZnCl2 and 2.5M NH4Cl electrolyte at pH 4.0. The discharge curve of the PANI-Zn batteries containing COMPOSITE active material showed lower internal resistance than PANI active material and maximum discharge capacity density and energy density increased up to 86.7 mAhg-1 and 101.44 Whkg-1, respectively (approximately 30% of theoretical value) compairing to 73.8 mAhg-1 and 71.58 Whkg-1 blended active materials. In addition, the PANI-Zn RECHARGEABLE BATTERY with COMPOSITE active material capacity reduced only 39% after 100 charge/discharge cycles. The mid-point voltages for two type of active material were 1170 mV and 970 mV, respectively. The PANI-Zn cell containing COMPOSITE active material showed better electrical performances for use as a secondary system.
