Olivine silicates LiMSiO4 (where M = Mn, Fe, Co, and Ni) are promising candidates for the next generation of cathode materials for use in lithium ion batteries (LIB). Among these compounds, LiFeSiO4 is an attractive choice due to its low cost, environmental friendliness, high safety, and stability In this work, we use first-principles density functional theory-based calculations to determine the structural and electrochemical properties of olivine-type LiFeSiO4 and LiFe05M05SiO4 (where M = Mg or Al).
