Aqueous zinc-ion batteries (ZIBs) represent an emerging energy storage solution that offers significant advantages in terms of safety, cost-effectiveness, and longevity cycling. Among the various materials available, manganese-based oxides stand out as most promising options for cathodes due to their impressive theoretical specific capacity, suitable operating voltage, abundant natural availability. In published reports, pre-embedding is frequently used modify layered cathode; however, non-electrochemically active molecular embedding often results a decrease battery capacity. this paper, hydrothermal method employed intercalate poly(o-phenylenediamine) (PoPD) into δ-MnO2 (MO) produce PoPD-MO cathode materials. Here, PoPD serves dual role cathode: (1) inserted interlayer MO, providing support within intercalation layer, enhancing material stability, increasing ionic sites, creating space more Zn2+ be embedded, (2) inserting structure MO effectively expands between layers, thus allowing greater ion storage, which turn enhances rate efficiency electrochemical reactions. Consequently, shows remarkable cycling durability adaptability ZIBs, achieving capacity 359 mAh g−1 at current density 0.1 A g−1, even under strain high 3 it maintains respectable 107 g−1. Based on this, may emerge new with applications future.
