摘要：

Chemical lithium extraction has been carried out on the following manganese oxides: the spinel-type compounds LiMn2O4 and Li4/3Mn5/3O4, and the rocksalt-related compound Li2MnO3. Lithium can be partially removed chemically from these compounds without destroying the host framework. Some compounds obtained by this method have been tested as cathodic materials in rechargeable lithium cells. Electrochemical results and X-ray diffraction patterns of cycled cathodes are presented. Electrochemical insertion/extraction of Li+ ions occurs with tetragonal/cubic distortion in the spinel framework, whereas Li+ ions can move in compounds having the rocksalt structure, without significant modification of the X-ray patterns.
