Abstract

Abstract : In article number 2001415, Jintao Zhang and co‐workers demonstrate the tunable formation of cationic vacancies in cobalt oxides via a thermal treatment strategy. The presence of cobalt vacancies regulates the electronic structure and charge‐transport properties of advanced bifunctional electrocatalysts, which significantly improve the electrochemical activities of lithium‐oxygen batteries with larger specific capacities and superior cycling stability.
