| titleOfInvention | Positive electrode material and preparation method and application thereof |
| abstract | The invention provides a positive electrode material and a preparation method and application thereof. The anode material is alpha-NaFeO 2 The chemical general formula of the cathode material is Li x Co 1‑y Al z M1 m M2 n O 2 Wherein, M1 is Ni and/or Mn, M2 is any one or the combination of at least two of Mg, Ti, Y, La, Zr, B, Nb, W, Sr, F, P or Ce, x is more than 0.98 and less than 1.04, Y is more than 0 and less than 0.06, z is more than 0.005 and less than 0.05, M is more than or equal to 0.001 and less than 0.02, and n is more than 0 and less than 0.05. The invention combines multi-element, multi-point, uniform and proper doping on the anode material, can obviously improve the energy density, power density and quick charge characteristic of the battery under high working voltage under the precondition of ensuring the safety of the battery, and improves the high-temperature storage, high-temperature floating charge, low-temperature discharge and high-temperature cycle characteristics of the battery. |
