Document Type and Number:
WIPO Patent Application WO/2024/066064
Kind Code:
A1
Abstract:
An oxide composite positive electrode material coated with copper oxide in situ, a preparation method therefor, and an application thereof. The chemical general formula of the oxide composite positive electrode material coated with copper oxide in situ is: γCuO-NaaCubMncMdO2+β; in NaaCubMncMdO2+β, Cu, Mn and M together occupy a transition metal site in a crystal structure; M is an element introduced through doping to substitute for the transition metal site; and γCuO is a coating layer generated in-situ on the surface of NaaCubMncMdO2+β by the Cu element added in excess during a sintering process for preparing the oxide composite positive electrode material coated with copper oxide in situ.
