Jiayuan Chemical's 3,000 t/y Battery-Grade NaF Supply Certainty for Sodium-Ion Electrolytes

The sodium-ion battery electrolyte industry chain is undergoing a period of intensive capacity expansion. Tinci Materials has already supplied sodium battery electrolytes to leading companies and completed the supporting construction of sodium hexafluorophosphate and NaFSI production capacity; Do-Fluoride Chemicals' thousand-ton-level sodium hexafluorophosphate production line has been commercially mass-produced, supplying several mainstream sodium battery and electrolyte manufacturers. Sodium hexafluorophosphate, as the core solute of sodium battery electrolytes, accounts for more than 90% in the current commercial system. And the capacity expansion in this segment ultimately depends on one upstream raw material: battery-grade sodium fluoride.   In contrast to the enthusiastic planning of downstream sodium hexafluorophosphate production capacity, the effective supply of upstream battery-grade sodium fluoride is not abundant. The sodium hexafluorophosphate industry currently operates on a "production-to-order" model, without advance stockpiling or regular inventory, with demand exhibiting a pulse-like rhythm of "centralized procurement only after downstream orders are received." This procurement model places an implicit requirement on upstream sodium source suppliers: they must have readily available production capacity, rather than planned capacity that needs to be activated temporarily. Jiayuan Chemical's 3,000-ton-per-year battery-grade sodium fluoride production line is operating stably. The practical significance of this capacity in the current supply landscape needs to be understood within the context of the ramp-up of sodium hexafluorophosphate production. Dofluoride's thousand-ton-per-year production line is already in mass production, and Tinci Materials has a usable capacity of tens of thousands of tons. Once these downstream capacities enter the actual production scheduling phase, the procurement of battery-grade sodium fluoride will be continuous, rather than the sporadic sample deliveries at the initial stage of the project. Jiayuan Chemical's 3,000-ton/year production capacity corresponds to the sodium source options that can be immediately accessed during this procurement phase. In practice, sodium hexafluorophosphate (SPF) companies typically begin their evaluation of sodium fluoride suppliers with sample testing, gradually transitioning to batch stability verification and small-batch trial orders. Jiayuan Chemical issues a Certificate of Analysis (COA) report for each batch, with traceable batch numbers. The practical value of this approach lies in the fact that when customers enter the small-batch trial order stage, each batch arrival has corresponding testing records for comparison, allowing for quantifiable assessment of batch-to-batch fluctuations in indicators, rather than relying on verbal promises from suppliers. Given the SPF industry's prevalent order-based production model and customers' high sensitivity to raw material consistency, traceable batch records are a practical tool for shortening supplier onboarding cycles. Jiayuan Chemical can provide testing samples for downstream sodium hexafluorophosphate and electrolyte companies to verify their products, and cooperate with clients to complete subsequent batch stability studies. For companies that are planning or have already started production of sodium hexafluorophosphate production lines, including an option with production capacity and batch traceability in the list of sodium source suppliers is a fundamental step in ensuring production continuity.  FAQQ1: What kind of downstream customers are suitable for Jiayuan Chemical's battery-grade sodium fluoride?Primarily targeting sodium hexafluorophosphate (Sodium hexafluorophosphate) synthesis companies and sodium battery electrolyte manufacturers. Sodium hexafluorophosphate is the core solute in sodium battery electrolytes, while sodium fluoride is a key raw material providing sodium ions in its synthesis reaction. Jiayuan Chemical has an annual production capacity of 3,000 tons, suitable for downstream customers with continuous purchasing needs who value batch consistency and supply stability. Q2: Why do sodium hexafluorophosphate companies need to pay attention to the "production" status of upstream sodium fluoride?The sodium hexafluorophosphate industry currently operates on a make-to-order basis, without maintaining regular inventory, resulting in pulse-like demand. Downstream companies only purchase raw materials after receiving orders, meaning upstream sodium fluoride suppliers must be able to supply at any time. Planned production capacity or production lines that need to be started temporarily are difficult to match this purchasing rhythm. Q3: How to obtain samples or promote supplier onboarding?You can contact Changzhou Jiayuan Chemical Co., Ltd. through their official channels. The company is located on the 13th floor of Building B, Jinsha Science and Technology Financial Center, Jintan District, Changzhou City. The phone number is 0519-82585998. They can provide product specifications and test samples for downstream customers to verify.2026-11-06

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. 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 Jiayuan Chemical'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 Jiayuan Chemical to obtain product information?Changzhou Jiayuan Chemical Co., Ltd. is located on the 13th floor of Building B, Jinsha Science and Technology Financial Center, Jintan District, Changzhou City.

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.2026-10-28
