In article number 1903265, Yong‐Mook Kang, Seong‐Ju Hwang, and co‐workers develop an efficient way to improve the electrocatalyst and Li–O 2 battery performances of metal oxide via synergistic control of structural disorder and surface bonding nature. The amorphization and iodate anchoring are quite effective in improving electrocatalyst/electrode functionalities of δ‐MnO 2 via the alteration of surface bonding character, the stabilization of Mn 3+ species, and the enhanced charge transfer of interfaces.
