Ternary NCM811 Cathode Sheet

Lithium Nickel Cobalt Manganese Oxide, Single/Double-sided Coating, Mass-produced Battery-grade Sheet, Customizable

Product Overview

NCM811 electrode sheet is a key cathode component for lithium-ion batteries, made of LiNi₀.₈Co₀.₁Mn₀.₁O₂. It features a layered structure with an 8:1:1 Ni-Co-Mn ratio, offering high energy density (over 280Wh/kg), long cycle life, and good rate performance, ideal for high-energy applications like electric vehicles.
While high nickel content boosts discharge capacity, it brings safety and stability challenges. The material reacts with CO₂ and H₂O during charging, requiring storage in dry, low-humidity environments to maintain performance.

Key Features

  • Layered structure with Ni:Co:Mn ratio of 8:1:1
  • Nickel enhances energy density while cobalt and manganese stabilize the structure
  • High nickel content provides superior discharge capacity
