"Energy Storage + Batteries" Explodes! Master the Four Core Raw Materials of Lithium-Ion Batteries (Including Leading Companies and Their Capacities)

Iron phosphate is a white or light-red crystalline powder, with applications spanning lithium iron phosphate (LFP) battery materials, catalysts, ceramics, and even as a nutritional supplement in bread and animal feed. China is the world’s largest producer and consumer; over 90% of domestic demand centers on LFP battery materials, whereas overseas demand leans more toward additive applications. Specifically, 98.14% of China’s iron phosphate output is used for LFP cathode materials, with only 1.86% allocated to additives and other uses. The mainstream production processes for iron phosphate are the iron-based, sodium-based, and ammonium-based methods—all fundamentally involving phosphoric acid plus an iron source, but differing in raw material selection, product quality, energy consumption, and waste treatment. Enterprises choose their process based on resource access and technological maturity: sodium-based producers—such as Longbai Group and Anada—are primarily titanium dioxide manufacturers that can utilize by-product ferrous sulfate; phosphochemical enterprises favor the ammonium-based method due to ready access to industrial-grade monoammonium phosphate. Anada is currently upgrading its sodium-based line to ammonium-based technology, though the ammonium-based method remains dominant across the industry. Market Demand New energy vehicles (NEVs) serve as the core engine driving iron phosphate demand. As global electrification accelerates, LFP batteries—prized for their cost-effectiveness—are gaining steadily in penetration across passenger and commercial vehicle segments. In China, LFP batteries accounted for over 60% of power battery installations in 2023, directly pushing annual iron phosphate demand beyond one million tons. Supportive policies worldwide further reinforce demand certainty. Energy storage has emerged as the second growth pillar. Grid integration of renewable energy and peak-load regulation needs are fueling large-scale expansion of the energy storage sector. Owing to their high safety and long cycle life, LFP batteries have become the preferred choice for energy storage systems: they accounted for over 90% of global energy storage battery shipments in 2023, and storage demand is projected to account for more than 30% of total iron phosphate demand by 2030. The iron phosphate industry is led primarily by phosphochemical enterprises possessing phosphate rock resources, while cross-sector players—including titanium dioxide producers—supplement supply via by-product feedstocks. Overall, capacity continues consolidating toward leading firms combining resource advantages with technological prowess. Current industry leaders include: 05 Upstream Raw Materials — Lithium-Ion Battery Separators 05-1 Market and Competitive Landscape Lithium-ion battery separators act as the battery’s "core gatekeeper": positioned between the anode and cathode, they permit only lithium-ion passage while preventing short circuits—making them an indispensable component. After two years of price competition, dry-process and wet-process separator prices remained at historic lows through end-2025—but clear signs of recovery emerged in H2: prices bottomed out in August and rebounded; by October, wet-process separator prices rose broadly by 10%; and by year-end, leading companies issued formal price-increase notices—strong signals that supply-demand dynamics have reversed and that a new upcycle in industry prosperity has begun. China’s separator shipment volume reached 22 billion square meters in the first three quarters of 2025, up 43% year-on-year; Q3 alone saw 8.35 billion square meters shipped, up 34% YoY. Competitive structure is also reshaping: in the wet-process segment, Enjie’s market share dipped slightly by 2 percentage points, while Hebei Jinli and Sinoma Technology rose to 18% and 14%, respectively; dry-process leader Shinyang Material surged 7.1 percentage points in market share, further squeezing smaller players. 05-2 Supply-Demand Dynamics New separator capacity coming online in 2026 will require ramp-up time, resulting in relatively low utilization rates; meanwhile, previously commissioned existing capacity will operate at full capacity. From a supply-demand perspective, total industry supply in 2026 is expected to reach 44.3 billion square meters, up 16% YoY; demand—driven jointly by power batteries and energy storage batteries—is projected to grow globally by ~29%, shifting the industry from oversupply into tight balance.
