Sichuan Wonaixi New Materials Technology Co., Ltd. (WONAIXI) is a professional manufacturer founded in 2012, focusing on the research, development, and production of rare earth functional materials. Certified as a National High-Tech Enterprise and a Sichuan Provincial SRDI Enterprise, the company supplies over 50 refined specifications of rare earth products, including high-purity rare earth salts, high-precision rare earth polishing powder, and full series zirconium salts. With an annual production capacity of 15,000 tons of high-purity rare earth salts and 3,000 tons of high-precision rare earth polishing powder, WONAIXI serves global customers across defense, aerospace, electronics, new energy, and catalyst industries.

The Challenge: Sourcing Customized Rare Earth Compounds for Battery Applications

Battery manufacturers, particularly those developing next-generation lithium-ion and solid-state batteries, require rare earth oxides, carbonates, and fluorides with precise purity levels, particle sizes, and chemical compositions. Off-the-shelf materials often fail to meet the exact specifications needed for cathode doping, electrolyte additives, or performance-enhancing coatings. Sourcing from a manufacturer that can tailor indicators, contents, and packaging is critical to achieving consistent battery performance and compliance with strict quality standards.

Industry Background: Growing Demand for Battery-Grade Rare Earths

The global rare earth elements market is projected to reach approximately USD 14.03 billion by 2025, with magnet applications accounting for 31.2% of total value (IMARC Group). Neodymium-Praseodymium (NdPr) demand is projected to grow at a CAGR of 8.4% through 2035 due to the expansion of the EV and wind turbine sectors (Arthur D. Little). High-purity rare earth fluorides market is forecast to grow at a CAGR of 5.5% from 2025 to 2031 (QY Research). This surge in demand places pressure on buyers to secure reliable OEM partners who can deliver customized rare earth compounds at scale. China's rare earth exports reached 62.6 thousand metric tons in 2025 (General Administration of Customs), highlighting the country's dominant role in the supply chain.
