General description

NMC622, electrode sheet, aluminum substrate, is a ready-to-use cathode for lithium-ion battery research. NMC622 is a quaternary lithium metal oxide, LiNi0.6Mn0.2Co0.2O2, and is a state-of-the-art cathode material for lithium-ion batteries that offers high energy density and cycle lifetimes. The composition of our cathode film is 90% active material, 5% PVDF binder, 5% carbon black.
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. Click here for more information.

Application

The main application of our NMC622 electrode sheet is as a cathode for next-generation lithium-ion batteries (LIBs). The 622 refers to the unique composition of the active material in which nickel provides high energy density while the manganese and cobalt help to stabilize the spinel crystal structure. As a result, our cathode sheet achieves high capacity (>166 mAh/g gravimetric capacity, 2.0 mAh/cm2 areal capacity) and long cycle lifetimes, while offering a high nominal voltage of 3.75 V vs. Li/Li+. The recommended charge rate for our sheet is 1C and discharge rate up to 5C.
