| Abstract: | To improve the specific of lithium ion batterise, main effort should be directed toward the synthesis of new positive electrode materials, i.e.. various lithiated oxide that could reversibly intercalate one Li atom per 3d-metal atom at about 4 V %versus% Li. Spinel lithium manganese oxide(LiMn2O4) attracted interest because of its economical and environmental advantages compared to other lithiated transition metal oxide such as lithium cobalt oxide(LiCoO2) or lithium nickel oxide(LiNiO2). However, efforts to substitute LiMn2O4 for LiCoO2, in commercial Li-ion batteries have not been successful due to the rapid capacity fade upon cycling. This capacity fading has been suggested to be due to spinel dissolution, the Jahn-Teller effect and lattice instability. In the paper, doped LiMn2-xCrxO4 compounds(0
