Lithium Hexafluorophosphate (LiPF6 BATTERY GRADE)

Description

1. Product Overview

Lithium Hexafluorophosphate (LiPF6) Battery Grade is the highest-purity lithium salt essential for formulating conductive electrolytes in lithium-ion batteries (LIBs). Its primary industrial use is enabling efficient ion transport between cathode and anode, directly determining a battery’s cycle life, thermal stability, and safety margin. As the most commercially viable and performance-critical electrolyte salt for EVs, ESS, and consumer electronics, LiPF6 represents a strategic bottleneck material in the global battery supply chain. Securing a reliable, high-purity LiPF6 source is therefore not a commodity purchase—it is a capacity-enabling, risk-mitigating decision for any battery cell manufacturer.

2. Key Specifications & Technical Characteristics

• Chemical Composition: LiPF6 (Lithium Hexafluorophosphate), CAS No. 21324-40-3

• Purity Grade: Battery Grade – ≥99.95% (typical); free acid (HF) ≤50 ppm; moisture ≤10 ppm

• Physical Form: White crystalline powder

• Particle Size Distribution: D50: 100–300 µm (customizable upon request)

• Bulk Density: 0.8–1.2 g/cm³

• Packaging Options:

  • 25 kg HDPE drums with aluminum moisture-barrier liner

  • 200 kg steel drums (UN certified)

  • 1,000 kg FIBC bags with inert gas purge (custom)

• Shelf Life: 12 months from date of manufacture when stored below 25°C in <20% RH environment; sealed under dry inert gas (N₂ or Ar)

3. Core Industrial Applications

• Primary Industries: Electric vehicle (EV) battery manufacturing, grid-scale energy storage systems (ESS), consumer electronics (smartphones, laptops), power tools, aerospace & defense batteries.

• Operational Use Cases:

  • Formulation of 1M LiPF6 in EC/EMC/DMC solvent blends for high-voltage NMC and LFP cells.

  • Custom electrolyte preparation for fast-charge or high-temperature battery designs.

• Performance Advantage over Alternatives:
  LiPF6 offers the optimal balance of ionic conductivity (>10 mS/cm), electrochemical stability window (up to 4.5 V vs. Li/Li⁺), and aluminum current collector passivation. Compared to LiBF₄ or LiTFSI, LiPF6 provides superior cost-per-performance ratio and established manufacturing infrastructure, making it irreplaceable for volume production.

• Efficiency & Durability Gain: Low free acid (<50 ppm) and moisture (<10 ppm) directly reduce HF generation during cycling, extending cell calendar life by up to 25% compared to standard-grade LiPF6.

4. Competitive Advantages

• Quality Consistency: Statistical process control (SPC) with full batch traceability; each lot certified via IC, ICP-OES, and Karl Fischer moisture analysis. Certificate of Analysis (CoA) provided per shipment.

• Supply Reliability: Dual-source production lines (Asia & Europe optional) with 10,000 MT annual capacity; safety stock buffer equal to 8 weeks of average demand.

• Logistics Capability: Temperature-controlled warehousing + inert gas blanket during transport; hazardous material (Class 8, UN 3260) certified logistics partners globally.

• Price Competitiveness: Direct-from-synthesizer pricing with no trader markup; long-term volume contracts with fixed escalation clauses available.

• Sustainability & Technical Support: Zero-liquid-discharge (ZLD) manufacturing process; full technical data sheets (TDS), Safety Data Sheets (SDS), and application engineering support for electrolyte formulation optimization.
