Abstract Aqueous ammonium‐ion batteries (AAIBs) enjoy the merits of resource affordability, environmental sustainability, and rapid ion transport capabilities. However, achieving both high capacity long lifetime, which are critical performance metrics for AAIBs, presents a significant challenge. This difficulty arises from fact that enhancing capacity, such as constructing multiple active sites, often results in degradation electrode structure. It is imperative to devise innovative strategies AAIBs. The novel high‐entropy electrolytes (HEEs) exhibit multi‐component disordered structure facilitates hinders dissolution elements materials, showing great potential enhance electrochemical performance. Herein, taking Prussian blue analogues (PBAs) an illustration, high‐performance AAIBs devised by HEEs. Benefiting synergistic effect cationic additives, ultra‐stable materials obtained while maintaining their inherent capacity. When using HEEs, it demonstrates remarkable with specific 86.8 mAh g −1 cycling stability 1700 cycles at 0.2 A . Furthermore, assembled full battery stable lifespan, demonstrating significance HEEs practical application thus laying out blueprint large‐scale energy storage.
