Zinc-based batteries have attracted attention for their safety in aqueous electrolytes with low cost, environmental friendliness, and high capacity. In this study, layered double hydroxide, a solid-state OH− ion conductor, was hybridized with sodium polyacrylate hydrogel to construct a strong elastic hydrogel electrolyte (PANa-LDH) with high OH− ion conductivity. PANa-LDH, KOH was introduced by dipping into 6.0 M KOH solution, showed a significantly high ionic conductivity of 0.213 S cm−1 at 30 °C. A solid-state battery was fabricated using nickel-cobalt hydroxide cathode, PANa-LDH electrolyte, and zinc anode. The high specific capacity of 287 mAh g−1 was obtained at 0.1 A g−1 with high energy and power densities of 212 Wh kg−1 and 73 kW kg−1 (based on the cathode weight), respectively.

Aqueous zinc‐ion batteries (AZIB) are increasingly recognized as a promising next‐generation energy storage technology, prized for their affordability and high safety profile. Yet, their widespread adoption is challenged by complex reaction mechanisms and the evolving nature of both the electrode material and interfaces, which remain critical barriers. This review underscores the utility of in situ and operando characterization techniques in AZIB systems, offering invaluable tools for tracking these intricate processes and deepening understanding of energy storage mechanisms. This review presents an extensive overview of cutting‐edge in situ and operando methods, emphasizing their crucial role in structural investigations of materials and interfaces during electrochemical processes. This review particularly focuses on the synergistic application of various in situ techniques, delving into the nuances of experimental setups and data interpretation. Finally, it addresses current challenges in the field and proposes potential strategies, aiming to enhance the impact and broaden the application of these techniques for future advancements and mechanistic insights in AZIB research.
