An ultra-high nickel ternary cathode material with high compaction and high energy density |
| abstract |
The invention discloses an ultra-high nickel ternary positive electrode material with high compaction and high energy density. The general formula of the positive electrode material is Lin Ni a Co b Mn c M d N e O 2 , and the positive electrode material comprises: Polycrystalline material and single crystal material; the weight part of the polycrystalline material is 45-90 parts, and the weight part of the single crystal material is 10-55 parts; the D50 of the polycrystalline material is the same as that of the single crystal material. D50 satisfies the relation: K=(D1‑D2)/D2, where 0≤K≤4. The beneficial effects of the present invention are as follows: the ternary positive electrode material of the present invention mixes the polycrystalline material and the single crystal material with different particle sizes according to an appropriate ratio, so that the single crystal material can be fully filled in the gaps of the polycrystalline material. In the preparation process, the water washing link is cancelled, and the dry process is adopted. Through the reaction between the coating agent and the free lithium on the surface of the material, a fast ion conductor is formed to coat the surface of the material, which improves the discharge specific capacity and simplifies the production process. Reduced cost while improving cycle and DCR performance. |
