Shanghai Jiafurui 3,000 t/y Battery-Grade NaF in Stable Production at 99.96% Purity

As the sodium-ion battery industry chain continues to raise its quality requirements for core fluorine source materials, the large-scale and stable supply capacity of battery-grade sodium fluoride is becoming a focus of attention for downstream sodium hexafluorophosphate and electrolyte companies. Industry analysis indicates that the domestic sodium hexafluorophosphate and lithium hexafluorophosphate processes are highly consistent, both using sodium fluoride as the only key raw material providing sodium ions in the synthesis reaction. The typical industry consumption is 0.27-0.28 tons of sodium fluoride per ton of sodium hexafluorophosphate. Shanghai Jiafurui Import and Export Co., Ltd.'s battery-grade sodium fluoride production line has achieved stable operation with an annual output of 3,000 tons.

The technical hurdles for battery-grade sodium fluoride lie primarily in two dimensions: purity and impurity control. According to the industry standard YS/T 517-2024 "Sodium Fluoride," the main content requirement for high-end battery-grade products is set in the range of ≥99.9%–99.99%, while ppm-level control is implemented for metallic impurities such as calcium, magnesium, iron, and nickel. Shanghai Jiafurui's recently produced batches have achieved a measured purity of 99.96%, placing them in the upper-middle range of this standard. Key metallic impurity indicators also meet battery-grade specifications, and each batch is accompanied by a Certificate of Analysis (COA) test report, with complete and traceable batch information.

From the perspective of the supply chain, large-scale production capacity of battery-grade sodium fluoride remains a scarce resource. Public information shows that some companies' electronic-grade sodium fluoride projects are still in the planning stage or have not yet been built and put into production. Meanwhile, sodium hexafluorophosphate, as a key material for sodium battery electrolytes, has been commercially mass-produced by leading companies such as Do-Fluoride Chemicals and is supplied to several mainstream sodium battery and electrolyte manufacturers. Stable demand for upstream high-purity sodium fluoride is forming. Shanghai Jiafurui's 3,000-ton/year production capacity provides downstream customers with a proven, mass-produced option for securing sodium supply.

Shanghai Jiafurui possesses a complete batch quality control system and testing capabilities. Its products are suitable for the synthesis of sodium hexafluorophosphate and the preparation of electrolyte materials for sodium batteries. Going forward, it will continue to advance sample delivery and joint verification work, focusing on the certification needs of downstream customers.

Q1: What standards does battery-grade sodium fluoride comply with?

The current standard is YS/T 517-2024 "Sodium Fluoride", which is managed by the Ministry of Industry and Information Technology and will be implemented from May 1, 2025, completely replacing YS/T 517-2009. This standard sets the main content requirements for high-end battery-grade products at ≥99.9%–99.99%, controls metal impurities at the ppm level, and also sets clear limits for indicators such as moisture and insoluble matter.

Q2: What is the production capacity of Shanghai Jiafurui's battery-grade sodium fluoride?

With an annual production capacity of 3,000 tons, the production line has achieved stable operation, product batch information is traceable, and a COA test report is issued for each batch.

Q3: How can I contact Shanghai Jiafurui to obtain product information?

Shanghai Jiafurui Import and Export Co., Ltd. is located on the 13th floor of Building B, Jinsha Science and Technology Financial Center, Jintan District, Changzhou City. The contact number is 0519-82585998. Product specifications and test reports can be provided for downstream customers to review.
