The aqueous hybrid ion batteries, due to electrode advantages combined with different battery systems, are promising energy storage systems. The severe side reaction caused by a highly active aqueous electrolyte is the key challenge that restricts its practical application. Exploring the microstructure of the electrolyte is of great significance to improving the electrochemical performance. Herein, the regulation mechanism of acylamide groups in an aqueous electrolyte is deeply investigated. Due to the strong coordination ability and hydrophilicity of the acylamide group, the solvation structure of cations can be regulated, and the activity of water molecules can be weakened by hydrogen bonds. Therefore, the Zn 2+ plating/stripping process on the anode side can be orderly regulated, and the stability of the crystal structure of the cathode also could be significantly improved. Consequently, after adding 5% polyacrylamide into the electrolyte, the zinc anode can withstand long-term plating/stripping over 120 h at 1 mA cm −2 and 0.25 mA h cm −2 . Also, the LiFePO 4 cathode could achieve a capacity resistance of 82% after 350 cycles at 0.5 A g −1 , far higher than the 24% of pure liquid electrolytes. This work provides a helpful guidance for designing the next generation of hybrid ion electrolytes.

Aqueous zinc‐based batteries are emerging as highly promising alternatives to commercially successful lithium‐ion batteries, particularly for large‐scale energy storage in power stations. Phosphate cathodes have garnered significant research interest owing to their adjustable operation potential, electrochemical stability, high theoretical capacity, and environmental robustness. However, their application is impeded by various challenges, and research progress is hindered by unclear mechanisms. In this review, the various categories of phosphate materials as zinc‐based battery cathodes are first summarized according to their structure and their corresponding electrochemical performance. Then, the current advances to reveal the Zn2+ storage mechanisms in phosphate cathodes by using advanced characterization techniques are discussed. Finally, some critical perspectives on the characterization techniques used in zinc‐based batteries and the application potential of phosphates are provided. This review aims to guide researchers toward advanced characterization technologies that can address key challenges, thereby accelerating the practical application of phosphate cathodes in zinc‐based batteries for large‐scale energy storage.
