General description

Lithium nickel cobalt aluminium oxide (NCA) 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

NCA is Aluminum doped Lithium nickel cobalt oxide (LNCO). Al doping is found very effective to suppress the cell impedance rise by stabilizing the charge-transfer impedance on the cathode side besides increasing the thermal stability of the material. NCA shows excellent electrochemical performance.

The NCA casted electrode sheets can be cut into appropriate size and is ready to be used in lithium ion batteries.
