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.
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.
