Shanghai Jiafurui'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.

Shanghai Jiafurui'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. Shanghai Jiafurui'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. Shanghai Jiafurui 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.

Shanghai Jiafurui 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.

Q1: What kind of downstream customers are suitable for Shanghai Jiafurui'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. Shanghai Jiafurui 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 Shanghai Jiafurui Import and Export 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.
