Cathode Precursor NCM811 (NICKEL COBALT MANGANESE)

Description

1. Product Overview
Cathode Precursor NCM811 is a high-nickel (80% Ni) ternary precursor engineered for the production of advanced lithium-ion battery cathodes. It is primarily used in electric vehicle (EV) and high-energy-density storage systems. The key value proposition is enabling superior energy density (≥800 Wh/kg at cathode level) while reducing cobalt dependency, directly lowering cell-level $/kWh. Strategically, NCM811 is critical for automakers and battery giants transitioning from NCM622/523 to next-generation high-nickel chemistries without sacrificing cycle life or thermal stability.

2. Key Specifications & Technical Characteristics

• Chemical composition: Ni : Co : Mn = 0.81 : 0.09 : 0.10 (molar ratio)

• Purity level: ≥99.9% (metal basis), impurities (Na, Fe, Ca, Cu, Zn) each ≤10 ppm

• Physical characteristics:

  • Form: Spherical or polycrystalline secondary particles

  • Color: Dark gray to black

  • Particle size (D50): 10–15 µm (customizable from 8–18 µm)

  • Tap density: ≥2.3 g/cm³

  • BET surface area: 5–8 m²/g

• Packaging options:

  • 500 kg FIBC (aluminized moisture-barrier bag inside)

  • 25 kg vacuum-sealed aluminum foil bags (for R&D or trial quantities)

• Shelf life: 12 months (stored under dry inert atmosphere, ≤10% RH, <25°C)

3. Core Industrial Applications

• Primary industries: EV battery manufacturing, high-end consumer electronics, stationary grid storage.

• Specific operational use cases:

  • High-energy-density EV cells (e.g., 300 Wh/kg+ pack-level)

  • Fast-charge capable cells (with doping modifications)

  • Long-cycle stationary storage (4,000–6,000 cycles at 80% retention)

• Why this product performs better:

  • Higher nickel content lifts energy density by ~15-20% vs NCM622, enabling longer vehicle range per charge.

  • Controlled particle morphology improves slurry dispersion and electrode calendering yield (>98%).

  • Low residual lithium (LiOH/Li₂CO₃ ≤2,500 ppm) reduces gas generation and improves high-voltage stability.

• Cost advantage: Lower cobalt per kWh → ~10% material cost reduction vs NCM622 at scale.

4. Competitive Advantages

• Quality consistency: Batch-to-batch CV <2% for composition, D50, and tap density – ISO 9001:2025 certified production line.

• Supply reliability: Direct access to nickel matte and cobalt sulfate from ESG-compliant refineries; production capacity 5,000 MT/month.

• Logistics capability: Warehousing in key ports (Rotterdam, Shanghai, Houston) with <5-day lead time for scheduled orders.

• Price competitiveness: Long-term contract pricing (12–36 months) fixed to LME nickel + cobalt index, no spot volatility pass-through.

• Sustainability: Full mass balance traceability; zero liquid discharge manufacturing; carbon footprint ≤12 kg CO₂e per kg of precursor.

• Technical support: Free cathode calcination optimization protocol; XRD and ICP-OES batch report included with every shipment.
