Abstract

Penelitian tentang pengaruh variasi konsentrasi doping kobal dalam pembuatan elektrolit padat menggunakan metode sol-gel yang diduga dapat meningkatkan konduktivitas material telah dilakukan. Konduktivitas dapat ditingkatkan dengan menambahkan doping kation seperti kobal. Pembuatan elektrolit padat NaMn_2-xCo_xO₄ dilakukan dengan pencampuran Na asetat 0,2 M, Mn asetat 0,3 M, Polivinil Alkohol dengan variasi Co asetat 0,025; 0,05; 0,1; 0,2; dan 0,4 M. Material yang dihasilkan dikarakterisasi menggunakan XRD, SEM-EDS dan LCR-meter. Hasil penelitian menunjukkan bahwa produk dengan konsentrasi dan doping tertinggi menghasilkan konduktivitas tertinggi yaitu sebesar 3,3174 x 10^-6 S/cm.
