Lithium Ferro Phosphate (LiFePO4) adalah kandidat yang menjanjikan sebagai bahan sumber energi elektrik yang ramah lingkungan. Penambahan Ni komposit dalam baterai berbasis Li-ion dapat meningkatan performa dari baterai LiFePO4. Dalam penelitian ini, LiFePO4 akan disintesis dengan menggunakan Fe2O3, H3PO4, dan LiOH melalui cara solid-state dan dilakukan perlakuan panas yaitu sintering. Setelah itu, prekursor dikompositkan dengan tiga variasi penambahan konten Nikel dalam % berat, yaitu 5, 7 dan 10% melalui metode solid-state dengan ball mill diberi label LFP/5-Ni, LFP/7.5-Ni dan LFP/10-Ni. Karakterisasi dilakukan menggunakan XRD dan SEM untuk mengamati efek penambahan Nikel pada struktur dan morfologi sampel yang dihasilkan.

Lithium Ferro Phosphate (LiFePO4) is a promising candidate as an environmental friendly electric energy sources. The addition of Nickel composite in Lithium-ion battery based can enhance the performance of LiFePO4 batteries. In this experiment, LiFePO4 was synthesized using Fe2O3, H3PO4, and LiOH by solid-state method and heat treated with sintering process. After that, the precursor were composited with the various Nickel composition, in % wt, 5, 7.5 and 10% with solid-state method by using ball mill and labeled as LFP/5-Ni, LFP/7.5-Ni and LFP/10-Ni respectively. The characterizations were made using XRD and SEM testing. These were performed to observe the effect of Nickel addition on structure and morphology of the resulting samples.
