In the 1990s, LiFePO4 (LFP) was discovered as a cathode material for Lithium-Ion batteries. The advantages of LFP include thermal stability, environmental impact, and potential of low cost as compared to the cathode chemistries containing cobalt. Currently, solid state and hydrothermal processes are used to synthesize LFP at the industrial scale. Recently, a melting-casting process to produce LFP cathode material begun. The motivation behind this new process is the great flexibility of raw materials including chemical makeup and particle size, commodity chemicals, with the benefits of increased kinetics in the molten state, energy efficiencies and costs savings are anticipated. Melting lithium-, iron- and phosphorus-baring precursors in near stoichiometric ratios and casting LFP material that forms around 1000°C requires fewer processing steps and shorter reaction time. Induction furnace is utilized to reduce the melting cycle time. Cast LFP samples were evaluated using microscopies, DSC, XRD, and battery assemblies in coin cells.
