Pengaruh Variasi Dopan Asam Terhadap Kinerja Baterai Sekunder Polianilina|Zn

Said Ali Akbar, Veinardi Suendo, Achmad Rochliadi

Abstract

Studi tentang baterai sekunder polianilina(PAni)|Zn telah banyak dikembangkan, tetapi sejauh ini masih belum ada penjelasan mengenai pengaruh asam terhadap kinerja baterai tersebut. PAni disitensis menggunakan metoda elektrodeposisi dengan tegangan 0,7 V selama 30 menit. PAni hasil sintesis dikarakterisasi menggunakan Voltammetri dan Spektroskopi Inframerah. Baterai PAni|Zn didesain dalam bentuk sandwich, kemudian pengukuran kinerja digunakan impedansi serta pengisian-pengosongan. Baterai dengan elektroda PAni-Cl dan PAni-Br mempunyai kinerja yang lebih baik dengan specific capacity saat ke-60 yaitu 55,4 dan 37,4 mAh g^-1. Pengukuran impedansi pada baterai dengan elektroda PAni-Cl, PAni-Br, dan PAni HClO₄, menunjukan resistance solution (R_s) secara berurutan yaitu 1,38; 2,56; dan 3,03 W dan resistance charge transfer (R_ct) 2,24; 2,97; dan 7,71 W. Oleh sebab itu, baterai PAni|Zn dengan dopan HCl menunjukkan kinerja terbaik dibanding dengan asam yang lain.
