NMC (Lithium Nickel Manganese Cobalt Oxide) Battery Cathode Material – NMC 811
Description
NMC batteries are a type of lithium-ion battery that use Nickel, Manganese, and Cobalt oxides as the cathode material. Each element contributes specific performance benefits:
-
Nickel (Ni): Increases energy density and overall capacity
-
Manganese (Mn): Enhances structural stability and supports the electrode
-
Cobalt (Co): Improves stability and boosts discharge capacity
NMC 811 is a high-energy variant containing a high nickel ratio (80%) and low manganese and cobalt content, resulting in significantly higher energy density and improved performance for modern applications.
Applications
NMC materials are widely used due to their high energy density, stability, and long cycle life. Typical applications include:
-
Electric vehicles (EVs) and electric powertrains
-
E-bikes and power tools
-
Consumer electronics such as smartphones and laptops
-
Solar energy storage systems
