Lithium- and Manganese-Rich (LMR) NCM cathodes (often written as xLi_2MnO3 * (1-x)LiMO2, where M = Ni, Co, Mn) represent one of the most promising "next-generation" cathode materials. They are designed to break the capacity ceiling of conventional NCM materials by utilizing both cationic (metal-ion) and anionic (oxygen) redox reactions.
The LMR NCM 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.
