General description

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.
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.
Lithium nickel cobalt mixed oxide which is a continuous solid solution series between lithium nickel oxide and lithium cobalt oxide is widely used as a positive electrode for Lithium Ion Batteries. Lithium nickel cobalt aluminium oxide (LNCA) belongs to this family of layered transition metal oxides and is used as a cathode in Lithium Ion batteries in plug-in electric hybrid vehicles. Aluminium substitution in the cathode increases the cycling and thermal stability.

Application

Lithium nickel cobalt aluminum oxide (LNCO) can be used as a thermally stable cathode material. It shows good cyclic performance and can be operated around 3.65V. It is further utilized in the fabrication of lithium-ion batteries for hybrid electric vehicles.
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.
