| titleOfInvention | Composite positive active material and lithium ion secondary battery |
| abstract | The present invention provides a composite positive electrode active material and a lithium ion secondary battery. The composite positive electrode active material includes: a positive electrode active material; and a coating material, which is located outside the positive electrode active material and coats the positive electrode active material. The positive electrode active material is a layered lithium composite oxide; the general formula of the layered lithium composite oxide is Li 1+x Ni a Co b Me (1‑a‑b) Q 2 , wherein -0.1≤x ≤0.2, 0≤a≤1, 0.05≤b≤1, 0.05≤a+b≤1, Me is selected from Mg, Zn, Ga, Ba, Al, Fe, Cr, Sn, V, Mn, Sc, Ti, At least one of Zr, Q is selected from at least one of O and F; the bulk phase structure of the coating material is P4 2 /mnm space group. The lithium ion secondary battery includes the aforementioned composite positive electrode active material. The lithium ion secondary battery of the present invention has higher energy density and better cycle performance under high voltage. |
