General description

NMC532, electrode sheet, aluminum substrate, is a ready-to-use cathode for lithium-ion battery research. NMC532 is a quaternary lithium metal oxide, with the formula LiNi0.5Mn0.3Co0.2O2, 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 NMC532 electrode sheet is as a cathode for next-generation lithium-ion batteries (LIBs). The 532 refers to the ratio of metals in the active material that combine to give the high performance: nickel provides high energy density while the manganese and cobalt help to stabilize the spinel crystal structure to extend the cycle lifetime at moderate-high operating temperatures. As a result, our cathode sheet achieves high capacity (>155 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+. NMC532 is the optimal composition to maintain the good thermal stability of low-nickel compositions (e.g. NMC111), while also having a high capacity close to the high-nickel-content materials (e.g., NMC811 and NMC622). The recommended charge rate for our sheet is 1 °C and discharge rate up to 5 °C.
