Polyaniline/Zn as secondary battery for electric vehicle base on energy return factor
Proceedings – Joint International Conference on Electric Vehicular Technology and Industrial, Mechanical, Electrical and Chemical Engineering, ICEVT 2015 and IMECE 2015

Study on polyaniline (PANI) as a cathode in the PANI/Zn secondary battery has been performed. PANI was synthesized using electrodeposition method on the surface of the Graphite Sheets (GS), at 0.7 V relative to the saturated Ag/AgCl. PANI film was characterized by FT-IR spectroscopy, UV-Vis absorption, and Raman spectroscopy. And then the potential of using the PANI film as an electrodes was studied in a rechargeable battery system. This battery system consisted of GS|PANI|ZnCl2(electrolytes)|Zn configuration. Battery performance tests were carried out through the charge/discharge processes for 60 cycles at a current of 10 mA. The measurement results found that the performance of the battery at the first cycle of 59.49 mAh g−1, while at 60th cycle were 55.42 mAh g−1, and the percent capacity loss until the last cycle was 6.77%. Meanwhile, Energy Return Factor (ERF) of PANI/Zn battery until last cycle was increase compare to the first cycle approximately 83.82%. Impedance measurements PANI/Zn battery showed the solution resistance (Rs) were 1.38 Q, while for charge transfer resistance (Rct) were 2.24 Q.
