In article number 1806706 , Xiangfeng Liu and co‐workers propose to tune the oxygen redox activity and reversibility in an Li‐rich Li 1.2 Mn 0.6 Ni 0.2 O 2 cathode by an integrated strategy involving Li 2 SnO 3 coating, Sn doping, and spinel phase combination. This synergy not only suppresses the lattice oxygen loss and improves the anionic redox activity and reversibility but also facilitates Li + migration, which enhances electrochemical performance.
