Polyaniline/Zn as secondary battery for electric vehicle base on energy return factor

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.
