Oxygen vacancy chemistry in oxide cathodes

Abstract

This review focuses on the chemical thermodynamics and reaction kinetics of intrinsic and anionic redox-mediated oxygen vacancies in oxide cathodes.

A prismatic alkali-ion environment suppresses plateau hysteresis in lattice oxygen redox reactions

“…Here, all characterization techniques consistently validate that the oxygen redox mechanism at the HVP region is based on the existence of Mn 4+ , which is consistent with the results of analogous oxygen redox materials. 6,17,29,39 We further explored the source of the electrochemical behavior underlying charge transfer in Mn–O–Mn from the phase dimension.…”
