Abstract:	Aqueous ammonium ion supercapacitors have garnered significant attention in recent years owing to their exceptional performance, environmentally sustainable, and safe nature, as well as their potential for cost-effectiveness. Despite notable progress in developing this technology, several challenges remain. These include identifying electrode materials with high specific capacity, comprehensively understanding the intercalation mechanism of ammonium ions, and clarifying how these ions interact with the electrode materials. This review article provides a comprehensive examination of the latest developments in the field, including aspects such as electrolyte composition, mechanisms of ammonium ion insertion, and advancements in electrode materials. Additionally, we offer insights into potential solutions to overcome the current limitations faced by ammonium ion supercapacitors, paving the way for further innovation and application of this promising technology.
