Lithium Nickel Manganese Cobalt Oxide (NMC) Tapes

Cathode Electrode Sheets

Layered Lithium Nickel Manganese Cobalt Oxide (LiNixMnyCozO2) is a widely used class of cathode material with NMC111 (LiNi1/3Mn1/3Co1/3O2, also known as NMC333) being the most common representative. However, Ni-rich NMCs (NMC811, 622, 532) are becoming more and more in focus now in current research due to their higher specific capacity and energy. Among these materials, NMC811 (LiNi0.8Mn0.1Co0.1O2) can deliver a high capacity of ∼200 mAh/g with an average discharge potential of ∼3.8 V (vs. Li+/Li), making it a promising positive electrode material for high energy density lithium-ion batteries.

NEI’S NMC electrode sheets are available in four different compositions: NANOMYTE® BE-50E (NMC111), BE-52E (NMC532), BE-54E (NMC622), and BE-56E (NMC811). Standard electrode sheets are 5 inches x 10 inches (127 mm x 254 mm) and cast either single-sided or double-sided on 16 µm thick aluminum foil current collectors. NEI also offers custom tailored solutions for customers with unique specification requirements. Our tapes can also be customized to accommodate different active material loadings, coating thickness, binder type (aqueous/non-aqueous), and binder content, as well as choice of current collector.
