Positive electrodes for lithium batteries
Abstract
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.
