Cathode Electrode Sheets

Lithium Nickel Cobalt Aluminum Oxide (LiNi_0.8Co_0.15Al_0.05O₂) is a cathode material that provides higher capacity than LiCoO₂ when both are charged to 4.2 / 4.3V. NCA-based batteries are most suited for use in moderate rate applications that require high energy density.

NANOMYTE^® BE-45E is a cast electrode tape of NCA powder. 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.

NEI’s Lithium Nickel Cobalt Aluminum Oxide is also available in powder form.
