LiFePO4 batteries in China are mainly sourced from western mineral regions and produced in advanced coastal factories. Lithium comes from Qinghai salt lakes, while iron phosphate is refined in central provinces and shipped to Shenzhen for cell manufacturing. Leading OEMs such as Redway Battery integrate materials, automation, and quality systems to deliver long-life forklift, golf cart, and energy storage battery packs worldwide.
What materials are sourced for LiFePO4 cells?
LiFePO4 cells rely on lithium carbonate, iron phosphate, phosphoric acid, and conductive carbon. Lithium carbonate is extracted from Qinghai and Tibet brines, while phosphate rock is refined in Yunnan, Guizhou, and Hubei. Redway Battery secures long-term contracts with battery-grade chemical suppliers to ensure stable purity levels and consistent performance for OEM customers.
| Material | Main Source Regions | Typical Purity | Cost Influence |
|---|---|---|---|
| Lithium Carbonate | Qinghai, Tibet | ≥99.5% | High |
| Iron Phosphate | Yunnan, Hubei | ≥99.0% | Medium |
| Phosphoric Acid | Sichuan | ≥85% | Low |
How is iron phosphate produced in China?
Iron phosphate is produced through wet chemical reactions that combine iron sulfate with phosphoric compounds under controlled pH conditions. The precipitate is filtered, dried, and calcined to create FePO4 powder. This scalable method supports the large output needed by factories like Redway Battery, ensuring stable cathode quality for forklift, telecom, and solar battery lines.

What are the key steps in LiFePO4 cell production?
Cell production begins with mixing lithium, iron, and phosphate compounds in precise ratios. The slurry is spray-dried, then sintered at high temperature to form olivine-structured cathodes. Electrodes are coated, cells are assembled in dry rooms, and every batch is formation-tested. Redway Battery operates fully automated lines to keep defect rates low and cycle life above 4,000 uses.
| Process Stage | Equipment Used | Core Parameter |
|---|---|---|
| Mixing | Planetary Mixer | Uniform slurry |
| Spray Drying | Centrifugal Dryer | Fine particle size |
| Sintering | Roller Furnace | 650–750°C |
| Assembly | Automated Line | <1% humidity |
Which factories lead LiFePO4 manufacturing in China?
Shenzhen and the Pearl River Delta are the main production hubs, hosting vertically integrated OEMs. Redway Battery stands out with four modern factories, over 100,000 ft² of production space, and ISO 9001 systems that support OEM and ODM orders for forklifts, golf carts, RVs, and energy storage markets.
