Ternary NCM811 Cathode Sheet, Lithium Nickel Cobalt Manganese
Oxide, Single/Double-sided Coating, Mass-produced Battery-grade
Sheet, Customizable
1. 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.
2. Key Features
It has a layered structure with an Ni:Co:Mn ratio of 8:1:1. Nickel
enhances energy density, while cobalt and manganese stabilize the
structure and improve safety. High nickel content provides high
discharge capacity but poses challenges to safety and stability.
