Lithium Manganese Nickel Oxide (LMNO / Spinel) Tapes

Cathode Electrode Sheets

Lithium Manganese Nickel Oxide / Spinel (LiMn1.5Ni0.5O4) is a cathode material that can be charged at high voltage (5V). Due to the high potential, the material has a higher energy density compared to lithium cobalt oxide and lithium iron phosphate. LMNO-based batteries can be used in high energy and high rate applications.

NANOMYTE® SP-10E is a cast electrode tape of Lithium Manganese Nickel Oxide (LMNO) powder, and NANOMYTE® SP-10CE is a cast electrode tape of our LATP-coated Lithium Manganese Nickel Oxide powder.  Both 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.

Both spinel materials are also available in powder form.
