Thin-film LiMn{sub 2}O{sub 4} electrodes that are deposited either by electron-beam evaporation or radio-frequency sputtering show electrochemical activity between 4 and 5 V vs. metallic lithium. This behavior is significantly different to that expected from a standard Li[Mn{sub 2}]O{sub 4} spinel electrode. The unusual electrochemical behavior of thin-film LiMn{sub 2}O{sub 4} electrodes can be accounted for in terms of a structural model that may be considered as an intergrowth of two spinels, Li{sub 8a}[Mn{sub 2}]{sub 16d}O{sub 4} and Li{sub 8b}[Mn{sub 2}]{sub 16c}O{sub 4}, where 8a and 8b refer to tetrahedral sites, and 16c and 16d refer to octahedral sites of the space group Fd3m.
