Preparation and characterization of LiMn2O4 powders by the emulsion drying method

Spinel-type lithium manganese oxide is evaluated as a positive electrode material for lithium-ion batteries. Powders of lithium manganese oxide are prepared by the emulsion drying method which is simplified by omitting the toluene washing stage. We investigated the powder and electrochemical characteristics of LiMn2O4 with lithium salts such as LiNO3 and LiOH•H2O.
