General description

Lithium nickel manganese cobalt oxide (NMC) is a class of electrode material that can be used in the fabrication of lithium-ion batteries. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Application

NMC is a novel lithium insertion electrode material for advanced lithium-ion batteries. Mn doping significantly increases the thermal stability besides increasing the electrochemical charge-discharge behavior.
NMC111 (lithium nickel-manganese-cobalt oxide with a stoichiometry of 1:1:1) is a promising cathode material used in advanced lithium-ion batteries, particularly for electric vehicle applications, due to its high energy density and long cycle life. NMC111 powder has a layered crystal structure that enables efficient, reversible lithium-ion diffusion, which is essential for good electrochemical performance. Manganese doping improves the thermal stability of the material while enhancing its electrochemical charge-discharge behavior. Compared to other NMC materials, NMC111 has a higher thermal stability and is less prone to thermal runaway, making it a safer option for battery applications.

Features and Benefits

Our NMC111 has engineered improvements over other LiNMC materials including thermal stability and high conductivity:
  • More Reliable
  • Longer Cycle Life
  • Bulk and Pilot Scale Available
