the structural stability of LiMn{sub 2}O{sub 4}, which is of interest as an insertion electrode for rechargeable lithium batteries, is discussed with respect to processing techniques, composition, the Li- Mn-O phase diagram, and electrochemical behavior. Particular attention is paid to processing conditions that result in the formation of lithium-magnesium-oxide spinel products in which Mn{sup 2+} ions partially occupy the tetrahedral sites of the spinel structure. The electrochemical behavior of electron beam and rf magnetron sputtered thin film electrodes suggests the existence of partially inverse Li{sub 1-x}Mn{sub 2} O{sub 4} spinel structures during an initial charge to 5.3 volts.
