Abstract

Lattice oxygen redox (LOR) in P2-type layered oxides is an effective strategy to break through the limit of energy density of conventional cathodes due to its high redox potential (>4 V vs Na+/Na) as well as extra capacity. Nevertheless, LOR-induced local structure distortion and irreversible phase transitions cause serious electrochemical performance degradation, hindering practical applications. Herein, we propose that the generation of the OP4 phase can be replaced with the Z phase by introducing the Sb element with a higher ionic potential and strong covalent bonds within the TMO6 octahedron. Z phase transition is realized by constraining interlayer slipping between adjacent transition metal (TM) layers…
