LAYERED OXIDE MATERIAL CONTAINING COPPER, AND PREPARATION METHOD AND USE THEREOF

摘要

Disclosed are a layered oxide material containing copper, and a preparation method and the use thereof. The material has the general chemical formula of Na0.68+aNibCucMdMneO2+δ, wherein Ni, Cu, M and Mn respectively form an octahedral structure with six nearest-neighbour oxygen atoms and form transition metal layers through an edge-shared arrangement; alkali metal ions Na+ are located between every two layers of transition metal layers; M is specifically one or more of Mg2+, Mn2+, Zn2+, Co2+, Al3+, B3+, Cr3+, Mn3+, Co3+, V3+, Zr4+, Ti4+, Sn4+, Mo4+, Ru4+, Nb4+, Sb5+, Nb5+, Mo6+ and Te6+; and a, b, c, d, e, δ and m satisfy (0.68 + a) + 2(b + c) + md + 4e = 2(2 + δ) and b + c + d + e = 1.
