The invention discloses a spinel lithium nickel manganate cathode ceramic material and a preparation method thereof. The molecular structure formula of the lithium nickel manganate is Li[(Ni a A b B c ) x (Mn d D e H f ) 2‑x ]O 4‑y E y , where 0.1≤x≤0.5, 0.01≤y≤0.1, 0.01≤a≤1, 0.00≤b≤1, 0.00≤c≤1, 0.00≤d≤1, 0.00≤ e≤1, 0.00≤f≤1, a+b+c=1, d+e+f=1; A is one or more of Zn, Sc, Nb or Cu, B is Be, La, Lu , one or more of Co, Cr, D is one or more of K, Na, Mg or Ca, H is one or more of Al, Fe, Ti, Mo or Ba, E is One or more of F, S or Cl. The electrochemical performance of the ceramic material is effectively improved by doping and coating technology. |
