Aiming at the disadvantage that the electrochemical cycle stability of lithium ion cell anode material lithium manganate (LiMn2O4) is poor, the invention provides a body phase-doped and modified spinel lithium ion cell anode material LiMn2-2xM(II)xTixO4 and a preparation method thereof, wherein M (II) is a divalent metal ion of Mg (Magnesium), Zn (Zinc), Ni (Nickel), Co (Cobalt) or Cu (Copper). The manganese contained in the material is replaced by doped tetravalent element and divalent metal which are equal in molar ratio to obtain the lithium ion cell anode material LiMn2-2xM(II)xTixO4 which has stable charge-discharge voltage platform, and relatively high discharge specific capacity and stable cycle performance so as to meet the requirement of high magnification charge-discharge; the preparation method overcomes the disadvantages that the synthesis time of a solid phase synthesis method is long, the particle sizes of a product are not uniformly distributed and the electrochemical performance is poor; the prepared product is good in reproducibility and chemical uniformity, fine in particles, high in purity and crystallization quality, excellent in electrochemical performance and low in production cost.
