Abstract
Sintesis Sodium Ferro Fosfat (NaFePO4) telah dilakukan dengan menggunakan metode sol-gel pada pH tepat 7 dengan 3 tahap yaitu pelarutan masing-masing bahan baku, pencampuran masing-masing larutan, dan penetralan pH serta pengeringan. Bahan baku yang digunakan merupakan bahan-bahan kimia berupa Na2C03, FeCl2.4H2O, (NH4)H2PO4 dengan bahan pelarut berupa ethanol dan aquades dan bahan penetral berupa NH4OH. Penelitian ini dilakukan untuk memperoleh kandidat material katoda NaFePO4 terbaik dengan melakukan variasi suhu kalsinasi 750°C, 800°C, dan 850°C, pada kondisi udara bebas dan atmosfir Argon. Karakterisasi yang digunakan adalah uji DTA-TGA untuk menganalisis perubahan termal, uji XRD untuk menganalisis pembentukan fasa, dan uji SEM untuk mengetahui morfologi pada fasa yang terbentuk. Hasil penelitian menunjukkan bahwa pembentukan fasa dipengaruhi oleh variasi suhu kalsinasi. Terbentuk 58,1% fasa Maricite-NaFePO4 pada suhu 850°C dengan intensitas rendah dan 94,9% fasa Maricite-NaFePO4 pada suhu 800°C menggunakan argon.
========================================================
Synthesis of Sodium Ferro Phosphate (NaFePO4) has been carried out using the sol-gel method at an exact pH of 7
with 3 stages namely dissolving each raw material, mixing the solution, and neutralizing the pH and drying. The raw
materials used are chemicals such as Na2C03, FeCl2.4H2O,(NH4)H2PO4 with solvents in the form of ethanol and aquades and neutralizing agents in the form of NH4OH. This research was conducted to obtain the best candidate NaFePO4 cathode material by varying the calcination temperature of 750°C, 800°C and 850°C, under the conditions of free air and Argon atmosphere. The characterization used is the DTA-TGA test to analyze thermal changes, XRD test to analyze phase formation, and SEM test to analyze of morphology in phase. The results showed that phase formation was influenced by variations in calcination temperature. 58,1% MariciteNaFePO4 phase was formed at 850°C with low intensity and 94.9% Maricite-NaFePO4 phase at 800°C using argon.
