Nickel-cobalt-manganese ternary positive electrode material nanorod and use thereof

Abstract

The present application discloses a nickel-cobalt-manganese ternary positive electrode material nanorod and the use thereof. The chemical general formula of the nickel-cobalt-manganese ternary positive electrode material nanorod is LiNiCoMnAlO, where 0<x<1, 0<y<1, and 0≤z≤0.05; the nickel-cobalt-manganese ternary positive electrode material nanorod has a section diameter of 50-200 nm and a length of 0.1-5 μm. In the present application, a mixed metal salt solution of nickel, cobalt, manganese, aluminum and lithium and 8-hydroxyquinoline are subjected to complex-precipitation to generate a precipitate containing nickel, cobalt, manganese, aluminum and lithium, and then the precipitate is calcined to prepare a ternary positive electrode material nanorod. Unlike traditional processes, no ammonia-nitrogen wastewater is generated in the whole process, and an alcohol used in the process can be directly recovered by means of evaporation and condensation, such that the process is environment-friendly.
