In this study, the synthesis, structural characterization, and electrical property analysis of LiMn 0.8 Fe 0.2 PO 4 (LM8F) its carbon-composite variant (LM8F-10%C) as potential cathode materials for solid-state lithium batteries were reported. Employing high-energy ball milling (HEBM) followed by calcination, LM8F was synthesized using ammonium dihydrogen phosphate, carbonate, manganese(II) acetate tetra-hydrate, iron(III) phosphate precursors. The introduction glucose a carbon source aimed at formation carbon-coated composite to enhance conductivity material. Structural morphological characteristics elucidated through X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FeSEM). XRD results confirmed olivine orthorhombic structure material, highlighting suitability use in batteries. Electrical properties assessed an LCR meter examine impact coating on electrochemical performance. findings demonstrated that inclusion significantly improved conductivity, potentially leading enhanced battery This work contributes development high-performance batteries, paving way future advancements energy storage technologies.
