In article number 2001050, Houzhao Wan, Ling Miao, Yi Wang, Hao Wang and co‐workers present the valence engineering of manganese oxide through bulk oxygen defects. The resulting material can act as a cathode material for aqueous zinc‐ion batteries. Valence engineering can change the [MnO 6 ] octahedral configuration of manganese oxide to improve structural stability and inhibit the dissolution of Mn 2+ , thereby greatly improving the cycle life of the battery.
