Abstract
Pada penelitian ini telah dibuat material katoda
LiFePO4/C baterai ion litium. Pembuatan material katoda
LiFePO4/C diproses melalui mekanisme solid state. Bahan
pembentuk dari material prekursor LiFePO4 adalah Fe3O4 yang
berasal dari batuan besi Kalimantan Selatan, (NH4)2HPO4 dan
Li2CO3. Bahan pembentuk tersebut dicampur pada ball milling
dan disatukan dengan karbon konduktif pada proses kalsinasi
500°C selama 8, 10 dan 12 jam. Hasil yang diperoleh
dikarakterisasi menggunakan instrumen X-Ray Diffractometer
(XRD), Particle Size Analyzer (PSA), Scanning Electron
Microscopy (SEM) serta battery analyzer untuk mengetahui
performa baterai. Analisis hasil pengujian XRD dilakukan
menggunakan perangkat lunak rietica. Hasil analisis
menunjukkan bahwa pada variasi waktu penahan proses kalsinasi
selama 8 dan 10 jam terbentuk fasa olivine (LiFePO4) yang
tertingi yaitu sebesar 85,7% dan 88,14%. Adanya peningkatan
fasa olivine pada material katoda LFP/C_8h dan 10h yang
terbentuk menyebabkan kenaikan nilai kapasitas discharging
yang dihasilkan yaitu sebesar 2,4315mAh/g dan 4,7815mAh/g.
==========================================================================================================
In this research, LiFePO4/C cathode materials Li-ion
batteries has been made. The making of LiFePO4/C cathode
materials were synthesized by solid state method. The formation
material used in this study is Fe3O4 from iron stone Kalimantan
Selatan, (NH4)2HPO4, and Li2CO3. These formation materials
mixed in ball milling and disatukan with conductif carbon at
calcination process 500°C during 8, 10 and 12 hours. The result
was caracterized by X-ray diffractometer instrument (XRD),
Particle Size Analyzer (PSA), Scanning Electron Microscopy
(SEM), and battery performance was detected by battery analyzer
. XRD test results was analysed by rietica software. The analysis
showed that the 8 and 10-hour’s holding time variation formed
optimum olivine phases that is 85,7% and 88,14%. The increase
phases which formed on LFP/C_8h and 10h cathode materials
cause increase capacity discharging percentage that resulted was
2,4315mAh/g and 4,7815mAh/g.
