Overview
The Lithium Hexafluorophosphate (LiPF₆) Production Equipment is a fully integrated system designed for the high-purity synthesis, purification, and handling of LiPF₆, a critical electrolyte salt used in lithium-ion batteries. The equipment ensures strict control over reaction conditions, safety, and environmental compliance to meet the demands of the energy storage and EV battery industries.
Key Components
Reaction System
Fluorination Unit: Converts raw materials (e.g., PCl₅, LiF, HF) into LiPF₆ via controlled fluorination reactions.
Corrosion-Resistant Reactors: Constructed from Hastelloy or nickel-based alloys to withstand highly corrosive HF environments.
Temperature & Pressure Control: Automated systems maintain optimal reaction conditions (±0.5°C accuracy).
Purification System
Crystallization Units: Recrystallization of LiPF₆ from solvents (e.g., anhydrous DMC/EC) to achieve ≥99.9% purity.
Filtration & Drying: Vacuum filtration and low-moisture drying (<10 ppm H₂O) to prevent degradation.
Handling & Safety
HF Scrubbing System: Neutralizes hazardous HF emissions via calcium hydroxide or alkali scrubbers.
Inert Atmosphere Processing: Argon/N₂ gloveboxes and sealed pipelines to avoid moisture/oxygen contamination.
Explosion-Proof Design: Compliant with ATEX/IECEx standards for organic solvent handling.
PLC/DCS Control: Real-time monitoring of pressure, temperature, and impurity levels (e.g., HF, H₂O).
Analytical Integration: online GC/FTIR for purity analysis and trace moisture detection.
Technical Specifications
Capacity: 500–5,000 tons/year (modular scalability).
Purity: ≥99.95% (battery-grade), residual HF<50 ppm.
Utilities: Chilled water (−40°C for condensation), ultra-dry air (<−60°C dew point).
Applications
Lithium-ion Battery Electrolytes: For EVs, consumer electronics, and grid storage.
Fine Chemical Synthesis: High-fluorine compounds.
Advantages
High Yield: Optimized reaction pathways minimize byproducts.
Moisture/Oxygen Control: ≤1 ppm O₂/H₂O in critical stages.
Turnkey Solutions: Customized for CAPEX/OPEX optimization.
Compliance & Certifications
Meets ISO 9001, IEC 61511, and GB/T 30884-2014 (Chinese battery-grade LiPF₆ standards).
Hazardous area certifications (e.g., ATEX Zone 1 for solvent handling).
Optional Add-Ons
Solvent Recovery Units (for DMC/EC recycling).
Packaging Lines: Under argon atmosphere for electrolyte-grade products.
