USE - For non-aqueous lithium cell (claimed) used for electric vehicles, hybrid electric vehicles and portable electronic components.    ADVANTAGE - The anode material is inexpensive, and has excellent thermal stability, cycling stability, reduced impedance, low toxicity, improved cycle life, electrochemical property and capacity.    DETAILED DESCRIPTION - An anode material made of substituted lithium nickel-manganese oxide consists of a composition of formula: Li1i+xNiapproximatelyaMnapproximatelybCoapproximatelycM'approximatelydO2-zXz, where M' is magnesium, zinc, aluminum, gallium, boron, zirconium or titanium, X is fluorine, sulfur, chlorine or iodine, x is 0-0.333, alpha is 0.2-0.6, beta is 0.2-0.667, gamma is 0-0.333, delta is 0-0.2 and z is 0-0.5. INDEPENDENT CLAIMS are included for the following:    (1) non-aqueous lithium cell. The non-aqueous lithium cell consists of a cathode, non-aqueous electrolyte and an anode. The anode consists of a composition of formula: Li1+xNiapproximatelyaMnapproximatelybCoapproximatelycM'approximatelydO2-zXz, where M' is magnesium, zinc, aluminum, gallium, boron, zirconium or titanium, X is fluorine, sulfur, chlorine or iodine, x is 0-0.333, alpha is 0.2-0.6, beta is 0.2-0.667, gamma is 0-0.333, delta is 0-0.2 and z is 0-0.5. x,alpha,beta,gamma,delta and z are controlled in order to fix the oxidation states of nickel, manganese and cobalt as Ni2+, Mn4+, and Co3+, respectively; and    (2) positive active material. The positive active material comprises a core consisting of composition of formula: Li1+xNiapproximatelyaMnapproximatelybCoapproximatelycM'approximatelydO2-zXz, where M',X,x,alpha,beta,gamma,delta and z are same as defined above. The core is provided with a surface layer or surface phase consisting of surface coating material comprising alkoxide, hydroxide and/or oxide. The surface-coated compound is heated, and hydroxide or amorphous oxide is formed on the compound surface.
