General description

NMC811, electrode sheet, aluminum substrate, is a ready-to-use cathode for lithium-ion battery research. NMC811 is a quaternary lithium metal oxide, with the formula LiNi0.8Mn0.1Co0.1O2, 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 NMC811 electrode sheet is as a cathode for next-generation lithium-ion batteries (LIBs). The 811 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. NMC811 (LiNi0.8Mn0.1Co0.1O2) is a highly nickel-rich NMC composition that is currently attracting considerable attention as a cathode material because it can deliver a high specific capacity of ~200 mAh g–1 with a high average discharge potential of ~3.75 V vs Li/Li+, resulting in a substantial increase of ~25% in energy density compared to LiCoO2.
