Abstract

Penelitian tugas akhir dengan judul “Sintesis Partikel LiFe1-xCuxPO4 berbasis Batu Alam dengan Variasi Doping Cu menggunakan Metode Hidrotermal” telah selesai dilakukan dengan menggunakan batu alam dari Kalimantan Selatan sebagai sumber Fe. Penelitian ini bertujuan untuk mengetahui proses pembentukan LiFePO4 dengan doping Cu menggunakan metode hidrotermal dan mengetahui pengaruh doping terhadap struktur kristal dan mikrostruktur pada partikel LFP. Metode hidrotermal pada penelitian ini tanpa menggunakan autoclave. Variasi doping yang digunakan yaitu Cu 0%, Cu 3% dan Cu 5%, sedangkan karakterisasi yang digunakan adalah FTIR, XRD dan SEM-EDX. Pola spektrum FTIR dari senyawa LiFe1-xCuxPO4 menunjukkan pola yang cocok dengan LiFePO4 menurut referensi. Analisis data XRD menunjukkan terdapat 2 fasa yang terbentuk pada sampel, yaitu LiFePO4 dan 1 fasa tidak terdeteksi. Analisis dengan perangkat lunak Rietica menunjukkan nilai volume sel pada sampel meningkat seiring dengan bertambahnya persentase doping Cu, sekaligus mengkonfirmasi keberhasilan doping. Hasil EDX menunjukkan bahwa sampel LiFe0,95Cu0,05PO4 memiliki homogenitas paling rendah daripada sampel LiFePO4 dan LiFe0,97Cu0,03PO4. Hasil ini juga menunjukkan kandungan Cu pada sampel LiFe0,97Cu0,03PO4 dan LiFe0,95Cu0,05PO4 masing-masing sebesar 0,42% dan 0,54%. ======================================================= ======================================= The final project entitled "Synthesis of LiFe1-xCuxPO4 Based on Natural Stone Particles with Variation of Cu Doped by Hydrothermal Method" was completed using natural stone from South Kalimantan as Fe source. This study aimed to determine the synthesis of LiFePO4¬ with Cu doped by hydrothermal method and to know the effect of doping on crystal structure and microstructure on LFP particles. Hydrothermal method in this study was applied without using autoclave. Variations of doping used were Cu 0%, Cu 3% and Cu 5%, while the characterization used was FTIR, XRD and SEM-EDX. Spectrum FTIR of the LiFe1-xCuxPO4 showed the same pattern as LiFePO4 by reference . Data analysis of XRD showed that there were two phases formed on the sample, those were LiFePO4 and the other was undetected. The analysis with software Rietica showed the volume value in the sample increased with increasing doping of Cu, it also confirmed the success of doping. The EDX results showed that the samples LiFe0,95Cu0,05PO4 had the lowest homogeneity of samples LiFePO4 and LiFe0,97Cu0,03PO4. These results also showed Cu component in LiFe0,97Cu0,03PO4 and LiFe0,95Cu0,05PO4 samples were 0.42% and 0.54% respectively.
