To meet the future development of high‐performance aqueous zinc ion batteries (AZIBs) with high energy density, low cost, and excellent cycle stability, an innovative strategy is developed to treat diamond residue graphite integrate nanostructured MnO 2 onto its surface via simple hydrothermal heat treatment methods. In @MG composite, presence modified (MG) restricts degree freedom growth, resulting in formation smaller structures avoiding accumulation aggregation , which helps improve interface charge transport composite electrodes. Meanwhile, MG could effectively slow structural collapse during charging/discharging conductivity . Based on synergistic core–shell structure, AZIBs employing exhibit superior capacity (332.0 mA h g −1 at 100 over 300 cycles), rate capabilities (208.1 500 ), outstanding cycling performance (48.1% retention after 2000 cycles) current density. This work demonstrates successful large‐scale conversion industrial into a cathode AZIBs.

Abstract Aqueous Zn/MnO2 batteries have been extensively attracted attentions for their superior comprehensive performance. However, the poor structural stability and dissolution of MnO2 seriously prevented its further development. Therefore, TiO2 is introduced coating to improve electrochemical stability. Firstly, used as a protective layer could hamper direct contact between electrode electrolyte, effectively inhibiting manganese. Secondly, has good mechanical strength adapt volume change during charge/discharge processes, which consolidates material. Finally, electrical conductivity composite material, achieving lower polarization electron/ion transport. As result, Zn/MnO2@TiO2-2 exhibits extraordinary performance with rate capacity 245.16 mAh g− 1 at 0.2 A maintains 137.09 after 1000 cycles 1 Ag− 1. Even high current density 3 1, it 93.35 1500 cycles, retention 97.47%. This work provides inspiration foundation method designing high-performance batteries.
