Summary: | The invention discloses a method for improving the performance of nickel-cobalt-aluminum-lithium oxide for a lithium ion power battery. According to the method, an organic titanate is adopted as a titanium source, the surface of nickel-cobalt-aluminum-lithium oxide is clad with titanium dioxide by virtue of liquid-phase chemical deposition, and then the cladding layer is partially nitrided to form a Ti-O-N cladding layer on the surface of nickel-cobalt-aluminum-lithium oxide. The cladding layer can be well bonded with nickel-cobalt-aluminum-lithium oxide; the direct contact between an active substance and an electrolyte is reduced, the electron conductivity between material particles can be improved, and the performance of the material can be improved. |
