▎ 摘　　要

NOVELTY - Double-ion battery anode material comprises at least one lithium-cobalt-metal-oxide-fluoride (I) and at least one sodium-iron-manganese-metal-oxide-fluoride (II). USE - The double-ion battery anode material is useful in anode sheet for secondary battery (all claimed). ADVANTAGE - The double-ion battery anode material: ensures the secondary battery with relatively high voltage platform and excellent rate performance. DETAILED DESCRIPTION - Double-ion battery anode material comprises at least one lithium-cobalt-metal-oxide-fluoride of formula (LiaCobM(1-b)O(2-c)Fc) (I) and at least one sodium-iron-manganese-metal-oxide-fluoride of formula (NapFexMnyN(1-x-y)O(2-z)Fz) (II). M = doping element including Ni, Mn, Ti, Mg, Fe, Cu, Ca, Sr, Sn, Zn, Y, Nb, Sb, W, Bi, Al, Cr, Zr, Mo, Te, Cd, Pd, Pb, Po, Ge, Si, La, Ba, B, Ce, Nd, Sm, Sc, Ru or Rh other than Co; a = 0.98-1.05; b = 0.1-1; c = 0-0.1; N = doping element including Li, Co, Ti, Mg, Ni, Cu, Ca, Sr, Sn, Zn, Y, Nb, Sb, W, Bi, Al, Cr, Zr, Mo, Te, Cd, Pd, Pb, Po, Ge, Si, La, Ba, B, Ce, Nd, Sm, Sc, Ru or Rh other than Fe and Mn; p = 0.5-1.01; x and y = 0.1-0.9; and z = 0-0.1. An INDEPENDENT CLAIM is also included for anode sheet, comprising double-ion battery anode material, a binding agent and a conductive additive.
