Lithium Cobalt Oxide (LCO) Tapes

Cathode Electrode Sheets

Lithium Cobalt Oxide (LiCoO2) was the first and most commercially successful form of layered transition metal oxide cathodes, and it is still used in the majority of commercial Li-ion batteries today. LCO is a very attractive cathode material because of its relatively high theoretical specific capacity of 274 mAh g−1, high theoretical volumetric capacity of 1363 mAh cm−3, low self-discharge, high discharge voltage, and good cycling performance.

NANOMYTE® BE-20E is a cast electrode tape of LCO 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.
