Product Overview
Lithium hexafluorophosphate (molecular formula LiPF₆) is a highly hygroscopic inorganic lithium-phosphorus-fluorine salt supplied as free-flowing white crystalline powder. When dissolved in carbonate-based organic solvents, this electrolyte salt delivers high ionic conductivity. It forms a stable solid-electrolyte interphase (SEI) on graphite anodes, making it the primary core raw material for liquid electrolytes used in consumer, power and energy-storage lithium-ion batteries.
Product Detailed Description
This lithium-containing electrolyte salt achieves its key electrochemical performance through its ionic molecular structure. When dissolved in mixed cyclic and linear carbonate solvents, it dissociates into lithium cations and hexafluorophosphate anions to form conductive electrolyte systems. Its distinctive anion structure supports a broad electrochemical stability window and promotes uniform SEI-film formation on anode surfaces. This protective barrier suppresses ongoing side reactions and extends cell cycle life. However, LiPF₆ is extremely moisture-sensitive; even trace water contact triggers hydrolysis, producing hydrogen fluoride and other by-products that degrade electrolyte properties and compromise battery safety.
Commercial-grade lithium hexafluorophosphate is predominantly produced as battery-grade crystalline powder. Rigorous limits on moisture, free-HF content, heavy-metals and foreign anions are mandatory for battery-grade specifications. Even ppm-level residual water or contaminants such as iron, sodium and calcium can accelerate internal cell side reactions, generate gas, and reduce finished-battery capacity and safety margins. In addition to liquid-electrolyte formulation for power batteries, consumer-device cells and energy-storage batteries, high-purity LiPF₆ supports lithium-battery laboratory research and specialized electrochemical-system development. Sampling, material transfer and packaging must all take place under inert-gas shielding to prevent hydrolytic degradation.
As a trusted chemical supply-chain provider, we enforce strict quality-control protocols for lithium hexafluorophosphate. Our battery-grade material maintains high active-component assays with closely monitored moisture, free-acid and multiple trace-metal parameters. Closed-loop production, purification and inert-atmosphere packaging workflows effectively minimize batch-to-batch variation. Consistent physicochemical specifications prevent quality drift that would otherwise result in defective electrolyte and under-performing battery cells for downstream new-energy manufacturers.
Purchasers gain tangible practical benefits by selecting our supply. First, consistent product specifications reduce repeated incoming-material laboratory testing for your technical teams and lower raw-material waste during continuous large-scale electrolyte-formulation production. Second, we provide comprehensive export-oriented documentation including COA and MSDS to streamline cross-border customs clearance and corporate safety-audit workflows. Third, purpose-built sealed inert-atmosphere packaging accommodates small-scale trial-batch orders as well as high-volume bulk-industrial procurement. Our technical team can share practical guidance on anhydrous-handling and storage best practices when customers encounter real-world production challenges.
We fully understand overseas buyers' key concerns around product stability, document completeness and safe transportation. Store this highly hygroscopic salt in hermetically-sealed containers within cool, dry, inert-atmosphere warehouse conditions. Strictly isolate it from humid air, water, protic solvents and strong oxidizing agents to avoid hydrolysis. Corrosion-resistant PPE and dry-box operating conditions are required for all material-handling operations. Every shipment undergoes pre-shipment inspection prior to dispatch. We have extensive export experience with high-purity lithium-series new-energy chemicals and maintain long-term stable partnerships with electrolyte and battery-material manufacturers worldwide. This proven track-record validates our reliable supply capabilities.

FAQ
Q1: What are the main application fields of Lithium Hexafluorophosphate?
A1: It is the primary electrolyte lithium salt raw material for liquid lithium ion battery electrolytes, widely deployed in power batteries, consumer electronic batteries and energy storage battery manufacturing. It is also used for laboratory scale lithium electrochemistry research.
Q2: Why is moisture control so critical for lithium hexafluorophosphate?
A2: Lithium hexafluorophosphate is highly hygroscopic. Trace level moisture initiates hydrolysis that yields corrosive hydrogen fluoride and other by products. These by products impair electrolyte performance, worsen cell side reactions, and degrade battery cycle life and overall safety.
Q3: What storage and handling precautions apply to this product?
A3: Store material inside hermetically sealed containers in cool, dry, inert atmosphere environments. Prevent exposure to humid air and liquid water. Perform all material transfer procedures inside dry box facilities while wearing corrosion resistant PPE.
Q4: Can you supply lab test samples for performance assessment?
A4: Yes, small quantity laboratory assessment samples are available with appropriate inert gas packaging. Buyers are responsible for associated sample related costs and freight charges.
Q5: What export supporting documents can you provide for shipment?
A5: We can furnish COA, MSDS, packing list and commercial invoice to support your import customs clearance procedures.
