Battery-Grade Phosphoric Acid (LFP Cathode Precursor)

Ultra-high purity phosphoric acid (>85% H3PO4, trace metal impurities <10 ppm) required as a precursor for synthesizing lithium iron phosphate (LFP, LiFePO4) battery cathode material. LFP is now the dominant battery chemistry in China's EV market and growing globally (Tesla Standard Range, BYD Blade Battery). The phosphoric acid pathway is: H3PO4 + Fe2O3 → FePO4 (ferric phosphate) → LiFePO4 (LFP cathode). Battery-grade requires much higher purity than food or industrial-grade H3PO4. Key producers expanding into battery grade: Hubei Xingfa (China), Guizhou Chanhen (China), ICL (Israel). China controls ~70% of global LFP cathode production.

7 companies produce battery-grade phosphoric acid (lfp cathode precursor).

Hubei Xingfa Chemicals Group(600141.SS)

HQ CN18% share

World's largest single STPP producer; 20-25% of global STPP market; 60,000 MT/year dedicated STPP capacity. China contributes ~80% of global STPP production, and Hubei Xingfa is the dominant Chinese producer. Also produces phosphoric acid, sodium hexametaphosphate (SHMP), and other phosphorus chemicals. Hubei province (also home to Three Gorges Dam) is a major Chinese chemical hub. Listed on Shanghai Stock Exchange. Serves food, detergent, water treatment, and industrial markets globally.

OCP Group

HQ MA15% share

World's largest phosphate company; controls ~70% of global proven phosphate rock reserves and 31% of world phosphate product market. Morocco's phosphate deposits (Khouribga, Gantour, Bou Craa) are the largest in the world. OCP controls 54% of global phosphoric acid trade and 26% of phosphate fertilizer market. Single-entity concentration of a resource essential for all animal and crop nutrition makes OCP a strategic geopolitical chokepoint.

Guizhou Chanhen Chemical Corporation

HQ CN12% share

Major Chinese phosphate chemical producer in Guizhou Province -- China's richest phosphate rock region. Produces phosphoric acid, MAP, DAP, and sodium tripolyphosphate. Expanding into battery-grade H3PO4 and ferric phosphate (FePO4) for LFP cathode supply chains. Guizhou province holds ~40% of China's phosphate rock reserves.

Wengfu Group

HQ CN10% share

One of China's largest phosphate chemical conglomerates; operates integrated phosphate rock mining through phosphoric acid to fertilizer production in Guizhou Province. Also producing battery-grade phosphoric acid and ferric phosphate as LFP battery supply chain demand grows. State-linked enterprise with significant Guizhou government backing.

ICL Group Ltd.(ICL)

HQ IL8% share

Israeli specialty mineral company; ~25% of global food phosphate market per input description; 15-18% of total global STPP market. ICL Food Specialties (subsidiary) is a leading food phosphate supplier: STPP, SHMP, SAPP, and other sodium phosphates for water binding, texture, and moisture retention in processed meat. Also: world's largest bromine producer (Dead Sea), potash producer (Dead Sea Works), and specialty fertilizer company. ICL has a unique triple position in critical minerals: food phosphates, potash fertilizers, and bromine for flame retardants/pharmaceuticals. Lawrence, KS plant serves the North American processed meat industry.

OCP Group

HQ MA6% share

World's largest phosphate rock producer and exporter; also largest single consumer of sulfuric acid globally. Consumed 11.3M MT H2SO4 in 2023 — equivalent to all of Germany's sulfuric acid output — to produce phosphate fertilizer at Jorf Lasfar complex. In January 2025 announced $1.2B investment to expand H2SO4 and fertilizer capacity. Produces H2SO4 on-site by burning imported elemental sulfur (shipped from Middle East producers and refineries). Morocco holds ~70% of global phosphate reserves.

Prayon Group

HQ BE

Belgian phosphate chemicals company with 140+ years of history (1882) and 1,400 employees. Produces purified phosphoric acids, phosphate salts (including food-grade STPP), and fluorine products at sites in Belgium, France, USA, and Switzerland. Prayon's wet-process phosphoric acid technology is used to produce over 50% of the world's merchant-grade phosphoric acid — making it the critical licensor of the key manufacturing technology behind the global phosphate supply chain. In August 2024, Prayon acquired Natural Enrichment Industries to strengthen its US footprint. Also a member of the European Sustainable Phosphorus Platform.
