Spinel type lithium-manganese oxide material, process for preparing the same and use thereof |
摘要 |
A novel lithium-manganese oxide composition suitable for use in lithium secondary batteries as an active material for positive electrodes, said oxide having a spinel type crystal structure, an Li:Mn molar ratio of 0.9-1.10:2.00, a mean Mn oxidation number of 3.40-3.60 valencies, and a BET specific surface area of at least 1 m<2>/g, substantially all the primary particles of said oxide being less than 1 mu m; a process for preparing such an oxide and a lithium secondary battery containing such an oxide are also disclosed. <IMAGE> |
