Lithium containing layered high entropy oxide structures.

ABSTRACT: Layered Delafossite-type Li_x(M₁M₂M₃M₄M₅…M_n)O₂ materials, a new class of high-entropy oxides, were synthesized by nebulized spray pyrolysis and subsequent high-temperature annealing. Various metal species (M = Ni, Co, Mn, Al, Fe, Zn, Cr, Ti, Zr, Cu) could be incorporated into this structure type, and in most cases, single-phase oxides were obtained. Delafossite structures are well known and the related materials are used in different fields of application, especially in electrochemical energy storage (e.g., LiNi_xCo_yMn_zO₂ [NCM]). The transfer of the high-entropy concept to this type of materials and the successful structural replication enabled the preparation o
