Jiayuan's 1,000 t/y Battery-Grade LiF Supply Certainty amid High-Energy Battery & Li-Salt Expansion

The high-energy-density lithium battery and next-generation solid-state battery industry chain is undergoing a period of intensive material iteration. In the electrolyte and electrolyte stage, lithium bisfluorosulfonyl imide (LiFSI) and lithium hexafluorophosphate (LiPF6) are rapidly moving towards higher purity and lower moisture content. Meanwhile, solid-state battery R&D companies are actively exploring the construction of artificial solid electrolyte interphase (SEI) layers using lithium fluoride. In these commercialized and cutting-edge technology systems, high-purity battery-grade lithium fluoride is an indispensable basic core raw material: it is not only the only fluorine/lithium dual-source precursor for mainstream lithium salt synthesis, but also a key special material for interface modification in high-energy-density batteries. In contrast to the fervor surrounding downstream high-energy-density battery material capacity planning, the effective supply of upstream high-purity battery-grade lithium fluoride is not abundant. Especially in the high-end synthesis sector, companies operate on a "production-to-order" model, strictly controlling raw material fluctuations. Demand exhibits a pulsed rhythm, with centralized procurement only occurring after process integration or downstream orders are received. This procurement model imposes an implicit requirement on upstream suppliers: they must possess readily available production capacity and guarantee extremely high batch consistency, rather than planned capacity that needs to be activated temporarily. Jiayuan Chemical's 1,000-ton-per-year battery-grade lithium 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 downstream customers' industrialization pace. Whether it's the expansion of lithium salt plants with capacities of tens of thousands of tons or the progress of solid-state electrolyte R&D companies from small-scale to pilot-scale testing, once these downstream capacities enter the actual production scheduling stage, the procurement of battery-grade lithium fluoride will be continuous, rather than sporadic sample deliveries at the beginning of projects. Jiayuan Chemical's 1,000-ton/year production capacity corresponds to readily available lithium/fluoride source options during this procurement phase. In practice, downstream material companies typically begin their evaluation of lithium fluoride suppliers with sample testing, gradually transitioning to batch stability verification and small-batch trial orders. Jiayuan Chemical achieves a measured purity of 99.9%, issuing 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. Batch-to-batch fluctuations in key indicators such as moisture and metal impurities can be quantified and assessed, rather than relying on verbal promises from suppliers. Given the high sensitivity of lithium salt synthesis and solid-state electrolyte preparation to raw material consistency, traceable batch records are a practical tool for shortening supplier onboarding cycles. Jiayuan Chemical can provide testing samples for downstream synthesis manufacturers and R&D companies to verify their products, and cooperate with customers to complete subsequent batch stability studies. For high-energy-density battery material production lines that are being planned or have already started production, including an option with production capacity and batch traceability in the raw material supplier list is fundamental to ensuring production continuity and process stability. FAQQ1: What kind of downstream customers are suitable for Jiayuan Chemical's battery-grade lithium fluoride?We primarily target three types of customers:1. Lithium/Sodium Salt Manufacturers: As the core synthetic raw material for the production of lithium hexafluorophosphate (LiPF6), LiFSI, and sodium hexafluorophosphate (NaPF6) (the key lies in reaction compatibility).2. Solid electrolyte R&D and materials companies: As raw materials for special materials, they are used to construct interface protective layers or synthesize specific components.3. Cell material layer research and development: used for electrolyte additive synthesis or positive and negative electrode interface modification. Q2: Why do downstream companies need to pay attention to the "production" status of upstream lithium fluoride?Currently, the high-end lithium salt and new materials industry largely operates on a make-to-order basis, without regular inventory, resulting in pulse-like demand. Downstream companies only purchase raw materials after receiving orders, meaning upstream lithium 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 procurement 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, with the telephone number 0519-82585998. They can provide product specifications and test samples for downstream customers to verify. Furthermore, the company strictly matches indicators according to the "synthetic application and customer process," avoiding any confusion between the uses of synthetic raw materials and additives, ensuring accurate and precise technical alignment.

Jiayuan Chemical 1,000 t/y Battery-Grade LiF in Stable Production at 99.9% Purity

With the continuous improvement of the quality requirements for core fluorine/lithium source materials in the high-energy-density lithium battery and next-generation solid-state battery industry chain, the large-scale and stable supply capacity of battery-grade lithium fluoride is becoming a focus of attention for downstream lithium hexafluorophosphate, lithium bisfluorosulfonylimide (LiFSI), and solid electrolyte companies. Industry analysis indicates that high-purity lithium fluoride is a key raw material for providing fluoride and lithium ions in the synthesis processes of mainstream lithium salts (such as LiPF6 and LiFSI) and new sodium salts (such as NaPF6). Changzhou Jiayuan Chemical Co., Ltd.'s battery-grade lithium fluoride production line has achieved stable operation with an annual output of 1,000 tons. The technological barriers to battery-grade lithium fluoride lie in three key areas: purity, moisture control, and metal impurity management. To meet the demands of downstream high-end lithium salt synthesis and specialty material development, battery-grade lithium fluoride typically requires a main content of ≥99.5% or higher, while stringent ppm-level control is implemented for metal impurities such as calcium, magnesium, iron, and nickel, as well as moisture. Jiayuan Chemical's recent mass-produced batches have achieved a measured purity of 99.9%, placing them at the forefront of the industry. Key metal impurity indicators and moisture content also meet battery-grade specifications. Each batch comes with a Certificate of Analysis (COA) test report, and the batch number information is complete and traceable. From the perspective of the supply chain, the large-scale production capacity of battery-grade lithium fluoride that meets the adaptability to high-end synthesis processes remains a scarce resource. Public information shows that some companies' high-purity lithium fluoride projects are still in the planning or ramp-up stage. At the same time, new lithium salts such as LiFSI and solid-state battery materials are accelerating their commercial mass production and supplying mainstream battery manufacturers. Stable procurement demand for upstream high-purity lithium fluoride is forming. Jiayuan Chemical's 1,000-ton/year production capacity provides downstream customers with a reliable option that has been successfully validated through mass production, ensuring a high-quality lithium/fluorine source supply. Jiayuan Chemical possesses a complete batch quality control system and testing capabilities.

Rare Gas Monthly (Oct 2026): Helium Down Faster, Xenon Off Highs, Krypton Still Weak

1. Market OverviewThe average monthly price of bottled helium declined this period, with weak market activity and pressure on manufacturers to move inventory, leading to a continued downward trend in transaction prices. As of October 28th, the mainstream transaction price for bulk bottled (40L, 13.5±0.5Mpa) high-purity helium in China continued to decline, with transactions concentrated at the lower end of the price range. Overall, bottled helium prices continued their downward trend in October, with intermediaries lowering their bulk purchase prices accordingly, and some lower-price negotiations increasing. In East China, manufacturers primarily focused on price reductions to move inventory, resulting in some low-price transactions; in Southwest China, mainstream transactions followed suit, with prices also shifting downwards.The price of imported and domestically produced high-purity helium in the Chinese market continued its downward trend this period. Gazprom's maintenance shutdown in early October reduced imports, which gradually resumed in late October, but overall supply remained ample. With continued increases in domestic helium production, market prices accelerated their decline. Mainstream ex-factory prices for high-purity helium in the Inner Mongolia and Shaanxi regions continued to fall. Market activity was generally subdued, with downstream buyers largely hesitant to purchase, adopting a wait-and-see approach.The average price of xenon declined this period, and the transaction focus shifted downwards. The imbalance between supply and demand for xenon has not yet eased, and prices continue their downward trend.The average price of kryptonite decreased this period, and the transaction focus shifted downwards. Downstream buyers maintained only essential purchases and were cautious about stockpiling. Under pressure, manufacturers and traders offered discounts to secure orders and accelerate the clearing of existing inventory.The average price of neon gas remained stable this period, while the transaction focus shifted downwards. Neon gas inventory in distribution channels was ample, resulting in a weak trading atmosphere.   2. Market OutlookThe high-purity helium market is expected to continue its downward trend in November 2026, but the decline in domestic helium prices will narrow. On the supply side, imported supplies are secured after Gazprom's maintenance shutdowns resumed, and large-scale domestic helium extraction projects are operating stably, resulting in a relatively ample overall supply. On the demand side, essential consumption from the medical and semiconductor industries provides basic support, but downstream end-users are cautious in their purchasing decisions, making it difficult to provide strong support in the short term. It is expected that the purchase price for imported high-purity helium tubing by intermediaries and the focus of negotiations among distributors will continue to decline; the decline in domestic high-purity helium tubing prices will narrow, and the distribution transaction range will be adjusted downwards at the end of the month. The bulk purchase price of bottled high-purity helium will also decline, and the focus of market negotiations will shift downwards.Xenon prices may still have room for a slight decline in November. Downstream demand continues to weaken, with most transactions being sporadic, immediate orders. The market lacks positive support, and prices may continue to fall slightly.The price of krypton gas is expected to continue its downward trend in November. Currently, downstream purchasing enthusiasm is insufficient, and manufacturers and traders are under great pressure to reduce their inventories. Market players are generally offering discounts to compete for orders, accelerate the turnover of goods, and recover funds.The neon market is expected to remain stable in November. Short-term spot trading is quiet, with supply and demand trending towards equilibrium. Producers and traders are mostly selling close to cost and have no plans for significant price adjustments.
