LiMn2O4 (LMO) Coated Aluminum Foil as Cathode Electrode (Disc, Sheet, Roll) for Li-Ion Battery, CLIBCELMO

The high-voltage lithium manganese oxide (LiMn2O4, LMO) coated on aluminum foil electrode (disc, sheet, roll) can be used as lithium-ion battery cathode. The round disc shape with single-side coating is suitable for coin cell testing, while the rectangle sheet shape with single- or double-side coating is designed for single-layer or multiple-layer pouch cell testing. The roll shape with double-side coating is designed for cylindrical cell electrodes after slitting.
