Abstract

Material katoda baterai ion natrium (NaFePO4) dengan struktur maricite disintesis menggunakan metode sol gel. Identifikasi fasa dan analisis struktur kristal menggunakan x-ray diffraction (XRD) dengan sumber radiasi CuKα. Struktur dan morfologi permukaan sampel dianalisis menggunakan scanning electron microscopy (SEM). Fasa maricite NaFePO4 muncul di semua atmosfir argon dan udara bebas baik sampel 1 ataupun sampel 2. Lamanya waktu pemanasan berpengaruh pada pembentukan fasa maricite. Pada udara bebas, semakin lama waktu pemanasan maka fasa maricite yang terbentuk semakin menurun presentasenya. Sedangkan pada atmosfir argon, semakin lama waktu pemanasan maka semakin besar presentase fasa maricite yang terbentuk. Morfologi permukaan partikel pada sampel NaFePO4 menglami aglomerasi dan memiliki bentuk yang tidak berukuran. Rata-rata ukuran partikel sekitar 0,921 μm. Melalui proses sintesis yang sederhana, maricite NaFePO4 dapat dipersiapkan untuk menjadi material katoda baterai ion natrium yang memungkinkan untuk aplikasi energi berskala besar dan penyimpanan stationer. ================================================================================================================== Sodium ion battery cathode material (NaFePO4) with maricite structure was synthesized using sol gel method. Phase identification and crystal structure analysis using x-ray diffraction (XRD) with CuKα radiation source. The structure and surface morphology of the samples were analyzed using scanning electron microscopy (SEM). The NaFePO4 maricite phase appears in all atmospheres of heat treatment, both sample 1 and sample 2. The duration of heating time affects the formation of the maricite phase. In air, the longer the heating, the lower the percentage of the maricite phase was formed. While in the argon atmosphere, the longer the heating, the greater the maricite phase was formed. The surface morphology of the particles in the NaFePO4 sample was agglomerated and had an irregular shape. The average particle size is about 0.921 μm. Through the simple synthesis prosses, maricite NaFePO4 can be prepared to be a cathode material for sodium ion batteries which allows for high energy applications and stationery storage.
