Abstract

Telah dilakukan penelitian untuk mensintesismaterial katoda Lithium Iron Phosphate (LFP). Sintesis material katoda LFP diawali dengan pembentukan prekusor FePO4 menggunakan metode kopresipitasi yang selanjutnya digunakan untuk pembentukan prekursor LFP dengan metode solid state. Penelitian dilakukan dengan bahan dasar serbukLithium Carbonate sebagai sumber ion Li,Iron(III) Chloride Hexahydrate sebagai ion Fe, Di-ammonium Hydrogen Phosphate sebagai ion phosphate. Pada penelitian inidigunakan variasi temperatur kalsinasi yaitu 500°C, 550°C, 600°C, dan 700° C dengan waktu penahanan selama 10 jam. Karakterisasi dilakukan dengan mengunakan pengujian Difraktometer Sinar-X (XRD), Scanning Electron Microscopy (SEM), Particle Size Analyzer (PSA), dan LCR Two Probe. Analisis data XRD dilakukan dengan menggunakan perangkat lunak X’pert High Score Plus (HSP). Hasil analisis menunjukkan bahwaprosentase fasa olivine dan konduktivitas listriktertinggi, yaitu 35% dan 0,0769 S/cm terbentuk pada temperatur kalsinasi 700oC. Partikel material katoda LFP berukuran mikron dalam rentang 0,8– 1,3μm seperti yang ditunjukkan berdasarkan pengujianParticle Size Analyzer (PSA).

Synthesis of cathode materialLithium Iron Phosphate (LFP) has been carried out. The first synthesis of cathode material LFP by usingcoprecipitation method to formFePO4 precursor and then to formLFP precursor by using solid state method. The research has been done using raw materials Lithium Carbonate as Li ion, Iron(III) Chloride Hexahydrate as Fe ion, and Di-ammonium Hydrogen Phosphate as phosphate ion. In this research were used various o fcalcination temperature by 500°C, 550°C, 600°C, and 700°C with holding time for 10 hours. Characterization were done using X-Ray Diffractometer (XRD), Scanning Electron Microscopy (SEM),Particle Size Analyzer (PSA), and LCR Two Probe. Analysis of the XRD data were done using software X’Pert High Score Plus (HSP). The result of analysis shown that percentage of olivine fase andelectric conductivity were the highest, there were 35% and 0,0769 S/cm made by calsination temperature 700oC. Particle of material cathode LFP was sized micron in scale 0,8 – 1,3μm showing by Particle Size Analyzer (PSA) test.
