The successful study of self-healing aqueous micro batteries (AMBs) which inherit the advantages and have ability to automatically repair damage is great significance for development smart wearable portable electronic devices. However, rate performance related power density developed AMBs using metal ions as charge carriers limited, due strong interaction between electrode materials. Therefore, there potential developing NH₄⁺ AMBs, because outstanding such extremely abundant reserves, smaller hydrated ion radius little molar mass. selfhealing still an challenge difficulty in hydrogels instability anode Even though, firstly based on tailoring hydrogel electrolyte MXeneintegrated perylene were successfully assembled. As expected, exhibit excellent energy (82.48 μWh·cm⁻²) (3.09 mW·cm⁻²), cycle life (81.67% after 3000 GCD cycles), flexibility (95.68% under 180°) (94.16% 10^th cycles).
