Abstract MnO 2 ‐based cathode aqueous rechargeable zinc‐ion batteries (ZIBs) have favorable sustainability characteristics and are considered potential candidates for low‐cost effective, high‐safety energy storage systems. Nevertheless, the development of them has been hampered by unstable electrode structures ambiguous charge mechanisms. Herein, role doping Fe 3+ Co 2+ into δ‐MnO materials (FMO, CMO) is comprehensively probed working mechanism Zn//FMO, Zn//CMO studied using in situ ex characterization, electrochemical analysis, theoretical calculations. Metal cations can partially replace Mn to form M─O bonds enhance structural stability as well redox activity . It found that effectively modulates interaction between Zn /H + structure inhibits formation ZnMn O 4 (ZMO) by‐products confers fast diffusion ability The reactions FMO CMO mainly via H /Zn intercalation/deintercalation accompanied OTF‐base‐like double hydroxide x (OTF) y (OH) 2x‐y ‐nH (Z‐LDH) deposition/dissolution. This research enriches fundamental comprehension ZIBs reveals way modify electrodes performance enhancement.
