MnVzO,, (0.5 < 6 < 1) amorphous oxides reversibly insert large amounts of Li (e.g. Li12MnV206,96) at low voltage (= 1 V). During the first Li insertion, Mn 4+ is first reduced to Mnz+ and Vs' is reduced to V3+. Upon further cycling, the V oxidation state varies reversibly between +3 and +5, whereas
