Product Introduction

Lithium Hexafluorophosphate LiPF₆ Production Line

We provide complete EPC turn‑key equipment for Lithium Hexafluorophosphate (LiPF₆) production plant, based on the mainstream industrial process: Yellow Phosphorus → Phosphorus Trichloride(PCl₃) → Phosphorus Pentachloride(PCl₅) → Phosphorus Pentafluoride(PF₅) → Lithium Hexafluorophosphate.

Our full‑set production equipment covers reaction, synthesis, purification, crystallization, drying, nitrogen‑sealed packaging, tail‑gas absorption & waste treatment units. LiPF₆ is the core lithium salt electrolyte for lithium‑ion batteries for EV, energy storage and 3C consumer batteries.

Key technical features

1. Strict anhydrous & oxygen‑free closed process, nitrogen protection system, avoid LiPF₆ hydrolysis and HF corrosion
2. Anti‑corrosion special material reactors for PCl₃, PCl₅, PF₅ synthesis
3. Integrated tail‑gas recovery and neutralization treatment system for corrosive waste gas(HF, HCl)
4. Automatic crystallization, drying and hermetic filling system for final LiPF₆ powder
5. Full‑process monitoring & safety interlock system for hazardous chemical production
6. Customizable capacity: small‑scale pilot plant to large‑tonnage commercial production line

We deliver whole‑plant solution including process design, equipment manufacturing, installation guidance, commissioning and technical training.

Core Production Purpose
Using yellow phosphorus as the starting raw material, it fully realizes the continuous full‑process production: yellow phosphorus → phosphorus trichloride → phosphorus pentachloride → phosphorus pentafluoride → lithium hexafluorophosphate, producing battery‑grade white crystalline powder of LiPF₆.
It completes synthetic reaction, purification and refinement, crystallization, vacuum drying, and anhydrous‑oxygen‑free closed powder filling to directly produce qualified finished products for electrolyte manufacturers.
Equipped with an exhaust gas treatment system to handle highly corrosive waste gases such as HF and HCl, as well as production wastewater and residues, to meet environmental compliance requirements for hazardous chemical chemical projects.

Application Scenarios at the Engineering Project Level

1. New‑built Factories: Deliver complete factory solutions for chemical enterprises and new‑energy investors. Covering process packages, equipment manufacturing, installation and commissioning, and personnel training to realize one‑shot commissioning and operation of factories (EPC Turn‑key).
2. Production Capacity Expansion: Expand lithium hexafluorophosphate units for aging chemical plants, supplying complete sets of equipment for reaction, drying and packaging units.
3. Process Upgrade and Retrofit: Renovate aging LiPF₆ production lines, upgrade closed anti‑corrosion systems, nitrogen protection systems and safety interlock systems to improve product purity and safety production levels.
4. Pilot‑scale Test Facilities: Customizable small‑scale pilot production lines for process testing and small‑batch trial production of battery‑grade lithium hexafluorophosphate products.
