NMC532

Description

• 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.
• 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.
