abstract = {Aqueous zinc-manganese batteries face the critical issue of irreversible dissolution/deposition of manganese dioxide (MnO2) stemmed from the disproportionation of Mn3+. Herein, the fluorine-doped manganese acetylacetonate-derived carbon (F-MDC) was designed as the cathode substrate to realize reversible dissolution/deposition of MnO2. An *OH-mediated deposition pathway of MnO2 was elucidated as follows: *OH → *MnOH → *Mn(OH)2 → *MnOOH → *MnO2. Attributed to the high electronegativity of fluorine on F-MDC, such pathway was promoted by accelerating the MnOOH dehydrogenation and strengthening the binding between Mn2+ and *OH, which could effectively avoid the disproportionation of Mn3+ and the formation of “dead MnO2”. The Zn-Mn battery based on F-MDC delivered a capacity retention rate of 91.7% after 4000 cycles at 3 A g−1 and still retained the specific capacity of 87.5 mAh g−1 even at a high current density of 10 A g−1. In addition, the assembled pouch cell also displayed standout rate capability, cycling stability and power supply performance.}
