GRADIENT-DOPED HIGH-NICKEL LAYERED OXIDE POSITIVE-ELECTRODE MATERIAL WITH HIGH-ENTROPY SURFACE AND MEDIUM-ENTROPY INTERIOR AND PREPARATION METHOD THEREOF

Resumen de: EP4682113A1

The present invention belongs to the technical field of lithium-ion battery electrode materials, specifically relating to a gradient-doped high-nickel layered oxide positive-electrode material with high-entropy surface and medium-entropy interior and a preparation method thereof. According to the present invention, the preparation method of the gradient-doped high-nickel layered oxide positive-electrode material with high-entropy surface and medium-entropy interior, involves doping the surface of the material with five or more elements to form a surface high-entropy reconstruction layer, while the interior of the material is doped with four elements to form a medium-entropy doping structure. The high-entropy reconstruction layer on the surface utilizes the synergistic effects of multiple elements to form a superlattice structure on the surface, so as to reduce the valence state of surface nickel, thereby stabilizing the interfacial structure and minimizing side reactions with the electrolyte. Through this method, the cycling stability of nickel-rich layered oxide positive-electrode materials can be significantly improved. It is a simple in process, low-cost, easy-to-operate, and high-performance method with promising prospects for industrial production and application.
