Abstract
Material natrium fero fosfat sebagai katoda baterai telah disintesis dengan menggunakan metode sol gel. Material katoda NaFePO_4 dibuat dengan menggunakan bahan bahan baku Na_2 CO_3, FeCl_4 H_2 O, dan NH_4 H_2 PO_4. Pada penelitian ini digunakan variasi atmosfir yaitu variasi argon 800℃ 5 jam dan 800℃ 7 jam dan variasi atmosfir udara bebas 800℃ 5 jam dan 800℃ 7 jam. Maricite NaFePO_4 merupakan fasa utama yang teramati dan terdapat fasa sekunder pada semua variasi sampel. Serbuk yang telah dikalsinasi dikarakterisasi menggunakan XRD, CV dan EIS. Hasil penelitian menunjukkan nilai selisih tegangan pada pengujian CV sebesar 0,3 V dan nilai impedansi sebesar 2 × 〖10〗^7 ohm.
==========================================================
The material of sodium fero phosphate as a battery cathode has been synthesized using the sol gel method. NaFePO_4 cathode material used raw materials of 〖Na〗_2 〖CO〗_3, Fe〖Cl〗_4 H_2 O, dan 〖NH〗_4 H_2 〖PO〗_4. The precursor of natrium fero phosphate has been calcinations in various atmosphere. The calcination various argon was varied at 800℃ 5 hours and 800℃ 7 hours and various free air was varied at 800℃ 5 hours and 800℃ 7 hours. Maricite NaFePO_4 is the main phase observed and there is secondary phase in all samples.The syntesized powders were characterized using XRD, CV and EIS. The results showed the voltage difference in the CV test of 0.3 V and the impedance 2 × 〖10〗^7 ohm.
