The electrochemical and structural properties of spinel phases in the Li-Mn-O system are discussed as insertion electrodes for rechargeable lithium batteries. In this paper the performance of button-type cells containing electrodes from the Li{sub 2}O yMnO{sub 2} system, e.g., the stoichiometric spinel Li{sub 4}Mn{sup 5}O{sub 12}(y = 2.5) and the defect spinel Li{sub 2}Mn{sub 4}O{sub 9}(y = 4.0), is highlighted and compared with a cell containing a standard LiMn{sub 2}O{sub 4} spinel electrode.
