As the electric vehicle and ESS markets expand, LFP is evolving into a cathode material that must combine cost competitiveness with higher density, improved performance and stable mass production. The focus of competition is therefore rapidly shifting beyond material composition to optimization across the manufacturing process—including FP precursor design, particle size control, calcination, carbon coating, milling and classification—and the capabilities of production equipment.

Recent developments in LFP/LMFP have seen an acceleration in high-density product development alongside a diversification of manufacturing methods. A wide range of routes is being adopted, including solid-state, co-precipitation, liquid-phase co-precipitation, sol-gel, hydrothermal, spray drying, iron oxalate and iron phosphate methods. For each route, raw material selection, reaction, drying and calcination conditions, and carbon coating methods directly affect final product quality and productivity.

In high-density LFP/LMFP development, precursor tap density, calcination temperature and atmosphere, carbon coating uniformity, moisture control, and second calcination and milling systems are emerging as key control factors. Other important considerations for manufacturing cost and quality competitiveness include the potential shift from roller hearth kilns (RHKs) to rotary kilns (RKs), next-generation precursor-free methods using Fe2O3, and new equipment such as dry mills capable of processing particles down to 300 nm and jet mills.

This report provides a comprehensive analysis of these developments, linking LFP/LMFP industry and technology trends with key technologies at each process stage, manufacturing methods, new high-density production methods, new equipment and actual process flows used by major manufacturers. Beyond introducing manufacturing methods, it examines critical process parameters and factors affecting quality, offering a view of how LFP/LMFP manufacturing technologies may evolve.

The report aims to provide practical insights for LFP/LMFP material and cell manufacturers, production equipment manufacturers, raw material and component suppliers, and companies using batteries. It helps readers understand changes in process technology and differences among manufacturers to support future technology development, equipment investment and business strategy.
