NMC811-Single Crystal

Overview

NMC-811-S is a nickel-rich layered oxide cathode active material based on LiNi₀.₈Co₀.₁Mn₀.₁O₂ (NMC811). Its single-crystal morphology is widely used in advanced lithium-ion research because it can reduce intergranular boundaries associated with polycrystalline agglomerates, helping researchers study degradation, surface stabilisation, and cycling durability under demanding conditions.

What it does in a battery

In a typical Li-ion cathode, NMC811 reversibly intercalates/de-intercalates lithium during charge and discharge. The high nickel content supports high specific capacity, while manganese and cobalt help stabilise the layered structure and improve rate/cycle behaviour when paired with appropriate electrolyte and voltage windows.

Key specifications (typical)

• Median particle size (D50): 4.0 ± 1.0 µm
• Specific surface area (SSA): 0.6 ± 0.2 m²/g
• pH: ≤ 11.7
• Residual OH⁻: ≤ 0.30 wt%
• Residual CO₃²⁻: ≤ 0.30 wt%
• Capacity: 210 ± 5 mAh/g
• Efficiency: 89 ± 1%
  
  

Compatibility and use

Suitable for standard cathode processing (e.g., PVDF binder + NMP, conductive carbon, Al foil current collector) and coin, pouch, or lab-scale cylindrical cell prototyping. As with most Ni-rich cathodes, dry handling and moisture control (e.g., glovebox transfer/storage) are recommended to support reproducible electrochemistry.

Typical applications

• High-energy density cathode screening and benchmarking
• Electrolyte/additive optimisation for Ni-rich chemistries
• Surface coating studies (stability, impedance growth, gas evolution)
• Fast-charge and high-voltage cycling research
