Coated Nickel Cobalt Manganese NCM811 Coating Material Lithium Niobate Single Crystal 811

Solid Electrolyte Coated Nickel Cobalt Manganese NCM811 Coating Material Lithium Niobate Single Crystal 811 Battery Material

Product Overview​​

Xwell's solid-state electrolyte-coated single-crystal NCM811 is a high-performance cathode material featuring lithium niobate surface modification. The blue-gray powder (3.535 μm D50) delivers 205.1 mAh/g initial discharge capacity at 0.1C with 89.1% efficiency, specifically optimized for all-solid-state battery research and development.

Key Specifications​​

Material Advantages​​

1. ​​Surface Engineering​​

   • Lithium niobate coating enhances interfacial stability with sulfide electrolytes
   • Reduces side reactions by 40% vs. uncoated NCM811

2. ​​Electrochemical Performance​​

   • Maintains >190 mAh/g at 1C rate (solid-state configuration)
   • Minimal gas generation (<0.5 mL/g after 100 cycles)

3. ​​Manufacturing Compatibility​​

   • Suitable for dry electrode processing (≤30% RH required)
   • Enables direct cold pressing at 300 MPa

​​Packaging & Storage​​

Handling Recommendations​​

1. ​​Material Preparation​​

   • Bake cathode sheets at 85°C for 4h before use
   • Perform all processing in dry room (≤0.1% H₂O)

2. ​​Electrolyte Pairing​​

   • Recommended electrolyte: KLD-1230C ternary formula
   • Coin cell assembly under <0.1 ppm O₂

3. ​​Safety​​

   • Hygroscopic material - minimize air exposure
   • Use vacuum-sealed transfer containers

Note: Custom coating thickness (2-10nm) and doping options available for research purposes.
