Active electrode material

Abstract

To provide an active electrode material with a high energy density, and a production method thereof.SOLUTION: The present invention provides an active electrode material represented by general formula M1aM22-aM3bNb34-bO87-c-dQd. In the formula, M1 and M2 are different; M1 is selected from Mg, Ca, Sr, Y, La, Ce, Ti, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Mn, Fe, Co and the like, and mixtures thereof; M2 is Zn or Cu; M3 is selected from Mg, Ca, Sr, Y, La, Ce, Ti, Zr, Hf, V, Ta, Cr, Mo, W, Mn, Fe, Co and the like, and mixtures thereof; Q is selected from F, Cl, Br, I, N, S, Se, and mixtures thereof; 0≤a<1.0, 0≤b≤3.4, -0.5≤c≤4.35, and 0≤d≤4.35; one or more of a, b, c and d are non-zero; and if a, b and d equal zero, then c is greater than zero.SELECTED DRAWING: None
