Title: Layered electrodes for lithium cells and batteries

Abstract

Lithium metal oxide compounds of nominal formula Li.sub.2MO.sub.2, 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 Li.sub.2MO.sub.2 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 LiMO.sub.2 electrodes. The Li.sub.2MO.sub.2 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.
