Ammonia-route precursor.
Modern cathode line.
Two stages, one circular loop. Proposed — diagrams are illustrative.
Our process has two stages. First, an ammonia-route process makes iron phosphate precursor from ferrous sulfate and monoammonium phosphate. Second, a cathode line converts that precursor into finished LFP cathode material.
Stage 1 — Iron phosphate precursor (ammonia route)
Ferrous sulfate and monoammonium phosphate react and precipitate iron phosphate. The precipitate is filtered, washed, and dried; calcination is optional. The filtrate is neutralized with ammonia, and ammonium sulfate is recovered as a by-product instead of being discharged as waste.
Stage 2 — LFP cathode line
Dried iron phosphate is mixed with a lithium source and carbon, then sintered in a roller hearth kiln, milled, coated, sieved with iron removal, and packaged. Quality control runs across both stages.
Circular utilities
The plant design recovers ammonia, reuses water with a zero-liquid-discharge intent, and automates material transport. Zero liquid discharge is a design intent for the proposed plant, not a verified operating result.
What is illustrative
Equipment counts, line counts, building footprints, temperatures as project setpoints, recovery rates, and yields are illustrative in the diagrams. The fixed anchor is the proposed 50,000 t/yr target. Literature ranges for LFP sintering are roughly 600–800 °C; they are not project specifications.
