摘要: Lithium metal oxide compounds of nominal formula Li2MO2, in which M represents two or more positively charged metal ions, selected predominantly and preferably from the first row of transition metals are disclosed herein. The Li2MO2 compounds have a layered-type structure, which can be used as positive electrodes for lithium electrochemical cells, or as a precursor for the in-situ electrochemical fabrication of LiMO2 electrodes. The Li2MO2 compounds of the invention may have additional functions in lithium cells, for example, as end-of-discharge indicators, or as negative electrodes for lithium cells.

摘要: This invention provides lithium-rich compounds as precursors for positive electrodes for lithium cells and batteries. The precursors comprise a Li2O-containing compound as one component, and a second charged or partially-charged component, selected preferably from a metal oxide, a lithium-metal-oxide, a metal phosphate or metal sulfate compound. Li2O is extracted from the above-mentioned electrode precursors to activate the electrode either by electrochemical methods or by chemical methods. The invention also extends to methods for synthesizing and activating the precursor electrodes and to cells and batteries containing such electrodes.
