A spinel oxide, Li 4 Mn 5 O 12 , is synthesized by a solution phase oxidation reaction of Mn 2+ with lithium peroxide in the presence of excess lithium hydroxide, followed by firing at T≦500° C. This material may be useful as a cathode for rechargeable lithium batteries. Samples fired at 400° C. and 500° …
