Jiayuan Chemical 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. Changzhou Jiayuan Chemical 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. Jiayuan Chemical'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. Jiayuan Chemical's 3,000-ton/year production capacity provides downstream customers with a proven, mass-produced option for securing sodium supply. Jiayuan Chemical 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. FAQQ1: 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.

Jiayuan High-Purity Hexafluoroisopropanol (HFIP) Targets Semiconductor and New Energy Industries

Jiayuan supplies 3N hexafluoroisopropanol (HFIP, CAS 920-66-1) with a purity ≥99.9%. 3N HFIP is not only a common solvent in pharmaceutical synthesis and polymer analysis, but it also unlocks high-end applications that industrial-grade HFIP (99.0%–99.5%) cannot reach. In advanced semiconductor processes and lithium-ion battery electrolytes, even trace impurities can cause a precipitous drop in performance, making 3N-grade HFIP an irreplaceable key material.   The watershed of 3N purityResidual fluorides, moisture, and metal ions in industrial-grade HFIP can interfere with precision manufacturing. Industry data shows that a purity of 99.95% to 99.99% is required to meet electronic-grade standards for photoresist cleaning of chips below 3 nanometers. 3N (≥99.9%) is a basic threshold for entering the semiconductor supply chain, and Jiayuan can provide batch-level testing data on metal ions, moisture, and fluorides to support certification. Special Application 1: Precision Cleaning of SemiconductorsHFIP has a boiling point of only 58.6°C (far lower than IPA's 82.4°C) and is non-flammable, eliminating the risk of combustion and explosion associated with traditional IPA cleaning. Early patents documented that wafers could be cleaned and dried simply by placing them in HFIP vapor, leaving no residue on the surface. The unique feature of Jiayuan's 3N grade lies in impurity control: photoresist residue cleaning requires the solvent not to introduce new metal ions or particles. Fluorides and moisture in low-purity products can cause surface defects, while the 3N grade uses processes such as molecular sieve membrane separation to reduce impurities to the ppb level. Special Application 2: Lithium-ion Battery ElectrolyteLithium hexafluoroisopropoxide (LiPOT), as an electrolyte additive, can preferentially reduce the graphite anode to form a more stable SEI film, suppressing side reactions and improving cycle stability. After addition, the electrolyte contact angle with the Celgard separator decreases from 41.0° to approximately 26°, reducing interfacial impedance. The significance of Jiayuan 3N's purity lies in moisture control: the electrolyte is extremely sensitive to moisture; even trace amounts of water accelerate LiPF₆ hydrolysis, leading to capacity decay. Jiayuan 3N HFIP typically maintains moisture levels below several hundred ppm, while industrial-grade moisture fluctuations can directly degrade batch consistency of batteries. FAQQ1: Is Jiayuan 3N HFIP equivalent to electronic grade?A: No, they are not the same. 3N (≥99.9%) is the minimum threshold for electronic grade, while the industry forefront has reached 99.99% (4N) to meet the requirements of processes below 3nm. Purity and metal impurity indicators should be confirmed according to the specific process node. Q2: Why does the lithium battery industry focus on HFIP derivatives rather than HFIP itself?A: HFIP functions as a film-forming additive in the form of lithium hexafluoroisopropoxide, and is a raw material for synthesizing this type of additive. Jiayuan's 3N grade reduces the introduction of impurities, ensuring additive consistency and electrochemical performance. Q3: What are the core advantages of 3N HFIP compared to IPA in semiconductor cleaning?A: Low boiling point of approximately 24°C, resulting in faster drying and lower energy consumption; non-flammable, eliminating the risk of combustion and explosion; good water compatibility, allowing for rapid replacement of moisture on the wafer surface; 3N purity ensures no metal contamination is introduced.
