The present invention discloses a lithium-rich anode material, a lithium battery anode, and a lithium battery, where the structural formula of the lithium-rich anode material is as follows: z[xLi 2 MO 3 ·(1-x)LiMeO 2 ]·(1-z)Li 3-2y M' 2y PO 4 , where 0 < x < 1, 0 < y < 1, 0 < z < 1; M is at least one of elements Mn, Ti, Zr, and Cr, Me is at least one of elements Mn, Co, Ni, Ti, Cr, V, Fe, Al, Mg, and Zr, and M' is at least one of elements Fe, Co, Ni, V, Mg, and Mn. Both the lithium battery anode and the lithium battery include the lithium-rich anode material. Because of the high capability of withstanding high voltages, the high initial charge-discharge efficiency, and the safety of the lithium-rich anode material, the lithium battery has excellent energy density, discharge capacity, cycle life, and rate performance. |
