摘要（英）：

The invention discloses a tin-contained layered oxide material and a preparation method and application thereof. The chemical general formula of the material is NaNiSnMO<2+beta>, wherein Mis an element obtained after transition metal is subjected to doping and replacement; a, b, c, d and beta are mole percents of corresponding elements; the relation among a, b, c, d and beta meets theequations of b+c+d=1 and a+2b+4c+md=2(2+beta) or a+3b+4c+md=2(2+beta); a is greater than or equal to 0.6 and smaller than or equal to 1; b is greater than 0 and smaller than or equal to 0.5; c is greater than 0 and smaller than or equal to 0.5; d is greater than 0 and smaller than or equal to 0.5; beta is greater than or equal to -0.02 and smaller than or equal to 0.02; and m is the valence stateof M. In NaNiSnMO<2+beta>, Sn ions with 4+ valence and Ni ions with 2+ valence have the same radius and tend to unordered distribution between transition metal layers. The crystal structure of the tin-contained layered oxide material is an O<3> phase, and the space group is shown in the description.
