I. Core Considerations for Procuring FEC Catalysts from China

FEC is a fluorine-containing fine electronic chemical and special electrolyte additive for lithium batteries. It has a low flash point and certain corrosivity, classified as hazardous flammable liquids in most regions worldwide. It is subject to regulations covering electronic chemicals, fluorinated substances, hazardous goods, REACH, and lithium battery industry access rules. The core performance of the product is determined by main content purity, water content, acidity, chloride ions, fluoride ions, alcohol residues, color, refractive index, electrochemical stability, and metallic ion impurities. Trace impurities will directly damage the SEI film structure, resulting in rapid battery capacity fade, poor low-temperature performance, aggravated self-discharge, cell swelling and gas generation. In addition, standards for hazardous goods transportation, electronic material access, and fluorinated substance control vary across countries. Procurement cannot rely solely on unit price comparison; comprehensive evaluation must be conducted in combination with electrolyte formulas, battery application scenarios, production processes, and local regulations.

(I) Compliance Qualification Verification: Align with Global Regulations to Ensure Customs Clearance, Production and Industry Access

Featuring triple attributes of hazardous flammable liquid, fluorine-containing fine chemical, and lithium battery electronic raw material, FEC is regulated by hazardous goods classification registration, REACH & SVHC control, fluorinated substance restrictions, electronic chemical hazardous substance management, and lithium battery material industry standards. Complete compliance documents serve as the foundation for cross-border circulation, industry admission, and risk avoidance.

1.

Specialized Testing and Certifications Matched with End Applications For general-grade FEC used in consumer digital batteries and small energy storage batteries exported to mainstream markets including the EU, North America and Japan & South Korea, REACH registration, full SVHC screening reports, as well as conventional anion, cation, residual solvent and color testing data shall be provided. Power-grade FEC dedicated to new energy power and vehicle lithium batteries requires supplementary automotive electronic material admission tests, low metallic ion analysis, and halogen control reports to meet stringent automotive electronic standards. Ultra-high-purity grade for long-cycle energy storage batteries and high-end cylindrical/pouch cells shall provide full-element trace impurity analysis and long-term electrochemical cycle test reports. Some countries impose special controls on fluorinated chemicals, requiring advance local filing of fluorinated substances.

2.

3.

Complete Documents for Cross-Border Transportation and Customs Clearance With a low flash point, FEC is uniformly categorized as a hazardous flammable liquid in most countries globally. Suppliers shall uniformly provide multi-language SDS safety data sheets, chemical hazard classification appraisal reports, corresponding UN numbers, hazardous goods packaging certificates, and maritime hazardous goods declaration documents. Conventional customs clearance documents include certificates of origin, batch-by-batch full-item COA quality inspection reports, and production traceability documents. For power battery and high-end energy storage grade orders, additional gas chromatography (GC), ion chromatography (IC), electrochemical performance evaluation reports, and actual battery cycle test data shall be attached.

4.

5.

Supplier Qualification Screening Prioritize source manufacturers with complete production capacity covering fluorination synthesis, multi-stage rectification, deep dehydration and impurity removal, and electronic-grade fine purification, who specialize in lithium battery electronic chemical production and boast long-term overseas lithium battery customer service experience. Key verification items include hazardous goods production qualifications, dust-free electronic chemical production qualifications, and the authority and traceability of third-party test reports. Insufficient main purity, excessive water/acidity, or high ionic impurities will directly lead to electrolyte failure, drastically shortened battery cycle life, cell swelling and gas generation, and elevated safety risks. Non-compliant indicators may also result in customs detention and trade claims. Qualification audits, electrolyte formula compatibility small-scale tests, and third-party full-item re-inspection must be completed prior to cooperation.

6.

(II) Raw Materials and Production Processes: Lock in Fluorination & Rectification Procedures to Stabilize Purity and Electrochemical Performance

The main content, impurity levels, electrochemical performance, and storage stability of FEC are fundamentally determined by the grade of upstream raw materials, fluorination process control, multi-stage vacuum rectification, deep dehydration, ion removal and other key procedures — these are also the core criteria for grading FEC for different lithium battery applications.

1.

Upstream Raw Material Inspection High-quality products adopt ultra-high-purity ethylene carbonate (EC) and high-selectivity fluorinating reagents as raw materials for targeted fluorination reactions under closed and controllable working conditions, minimizing by-product generation. Subsequent multi-stage high-efficiency rectification, molecular sieve deep dehydration, ion exchange impurity removal, and precision membrane filtration maximize the removal of water, organic acids, various inorganic ions, residual alcohols and light component impurities. Finished products feature high main purity, extremely low impurities, wide electrochemical windows, stable film-forming performance, strong compatibility with all types of electrolyte systems, and resistance to discoloration and acidification during long-term storage. Low-end products adopt industrial-grade raw materials with simplified rectification and impurity removal processes, suffering from low purity, excessive water and acidity, high ionic impurities, yellowing after long-term storage, and rapid degradation of electrochemical performance. Such products are completely inapplicable for high-demand scenarios including power batteries and long-cycle energy storage batteries. For high-end grades, suppliers may be requested to provide raw material purity certificates.

2.

3.

Confirmation of Core Production Processes Mainstream process route: Pretreatment of high-purity EC raw materials → Targeted fluorination reaction in closed system → Neutralization of crude liquid to remove by-products → Multi-stage vacuum rectification for component cutting → Continuous deep dehydration via molecular sieves → Ion exchange to remove trace anions/cations → Filtration with high-precision filter elements → Filling under inert nitrogen protection → Light-proof sealed warehousing.

4.

· General digital battery grade: Standard fluorination + two-stage rectification process, balancing cost and basic film-forming performance, suitable for consumer batteries such as mobile phones, earphones and power banks.

· Special power battery grade: Three-stage rectification + deep ion removal with strict control of metallic and halogen ions, tailored for vehicle power lithium batteries.

· Ultra-high-purity energy storage battery grade: Full-process dust-free production, multi-stage deep purification + extreme dehydration and impurity removal with strict control of trace impurities, suitable for large-scale energy storage and long-service-life batteries. Formal production lines operate fully sealed to isolate water vapor and air. High-end lithium battery grades are equipped with independent dust-free workshops and dedicated pipelines to avoid cross-contamination; counterfeiting of high-purity lithium-grade products with low-grade materials is strictly prohibited.

1. Quality Control and Production Capacity Assessment FEC is manufactured via continuous fine chemical production. Conventional grades are in sufficient stock, while customized ultra-high-purity grades are produced to order. Request multi-batch COAs, GC purity analysis, ion chromatography tests, water titration, and electrochemical cycle test data, with close monitoring of fluctuation ranges for key indicators including FEC main content, water content, acidity, chloride ions, fluoride ions, alcohol residues, metallic ions, and color. For long-term cooperation, lock raw material standards, process parameters and testing methods to guarantee consistent electrolyte compatibility and battery cycle performance across batches. Prioritize manufacturers with independent fluorination synthesis and deep purification capacity; products purchased as crude liquid and simply rectified and repackaged are prone to excessive impurities and unstable performance. Stability data under high-low temperature and long-term sealed storage shall also be provided to adapt to ocean shipping and warehousing environments worldwide.

(III) Grade, Specification and Formulation Matching: Model Selection Based on Battery Scenarios to Avoid Parameter Mismatch

Commercial FEC is classified by purity grade, impurity control standards, and metallic ion limit values. Incorrect model selection will cause defective SEI films, sharp battery cycle capacity drop, sudden low-temperature capacity loss, gas generation and cell swelling. Precise matching with battery types and electrolyte formulas is mandatory.

1. Classification by Application Grade

· General digital battery grade: Meets basic requirements for small consumer batteries with conventional electronic chemical impurity standards.

· Special power battery grade: Strict control of halogens and metallic ions for vehicle power lithium batteries.

· Ultra-high-purity energy storage battery grade: Extreme control of all trace impurities for large-scale energy storage and long-life batteries. Grades cannot be substituted for one another.

1.

Physical and Chemical Indicator Adaptation FEC is a liquid product. Confirm color, refractive index and low-temperature fluidity in combination with electrolyte formulas to ensure smooth batching at low temperatures and no system stratification. Clarify nominal values and allowable deviations for all physical and chemical indicators and impurity limits in contracts.

2.

3.

Agreement on Core Indicators Procurement contracts must clearly specify nominal values and allowable deviations for key indicators including FEC main purity, water content, acidity, chloride ions, fluoride ions, total metallic ions, and alcohol residues — these serve as core criteria for goods acceptance, formula compatibility and performance evaluation upon arrival.

4.

5.

Packaging and Minimum Order Requirements As a hazardous flammable and corrosive liquid, FEC is conventionally packed in galvanized iron drums or stainless steel drums lined with fluorine-resistant anti-corrosion inner films. High-end ultra-high-purity grades are filled with nitrogen inside drums to isolate air. The industry adopts kilograms and tons as order units. Confirm minimum order quantities and production lead times in advance for customized ultra-high-purity grades. Small sample verification must be completed before mass orders, including electrolyte compatibility tests, small-battery cycle tests, and low-temperature performance tests.

6.

(IV) Commercial Clauses and Full-Link Cost Accounting: Comprehensive Calculation of Usage Cost Based on Hazardous Flammable Liquid Properties

As a hazardous flammable liquid, FEC incurs additional costs including anti-corrosion packaging, hazardous goods packaging, hazardous transportation, special security, and cargo insurance. Procurement decisions cannot rely solely on per-drum unit price; comprehensive usage cost shall be calculated based on purity, impurity content, addition ratio, battery yield, and cycle life.

1. Quotation Modes

Specify internationally recognized third-party re-inspection institutions, re-inspection procedures, return/replacement rules and compensation terms. Meanwhile, clarify that minor color changes within standard ranges under normal sealed storage and transportation are normal phenomena to clearly divide liabilities between both parties.

2.

3.

Minimum Order Quantity and Warehousing Agreements Orders are placed in kilograms or tons; high-purity lithium battery grades cannot be split from original packaging. Mandatory storage requirements: Cool, ventilated, constant-temperature and dry environment with complete sealing at 5~30°C; high temperature, direct sunlight, open flames, oxidants, strong acids and strong alkalis are strictly prohibited.
