Abstract Ammonium‐ion supercapacitors (AISCs) offer considerable potential for future development owing to their low cost, high safety, environmental sustainability, and efficient electrochemical energy storage capabilities. The rapid charge‐transfer process at the AISC can endow them with capacitive cycling stabilities. However, prolonged intercalation/deintercalation of NH 4 + in layered framework materials often results cleavage active sites deconstruction framework, which makes it difficult achieve long‐term stable while maintaining capacitance electrode materials. Herein, highly redox‐active polyoxometalates (POMs) modified [Ag 3 (µ‐Hbtc)(µ‐H 2 btc)] n (Ag‐BTC) is used as POMs effectively promote pseudocapacitance through a similar interface mechanism. At current density 1 A g −1 , {PMo 12 }@Ag‐BTC exhibited specific 619.4 mAh retained 100% its after 20,000 charge–discharge cycles. An asymmetrical battery {PW positive negative materials, respectively, achieved an 125.3 Wh kg . interface‐capacitance enables full utilization metal‐O x (x = b, c, t) within POMs, significantly enhancing charge storage. This study emphasizes POM‐based
