Synthesizing Lithium Iron Phosphate (LFP) using an Iron(III) Phosphate (FePO4) precursor is one of the most common industrial routes. The process typically involves a carbothermal reduction. Since the iron in the precursor is in a +3 oxidation state (Fe^{3+}) and LFP requires iron in a +2 state (Fe^{2+}), a reducing agent (usually carbon) is necessary.
