This invention provides a fibrous flexible aqueous zinc battery, its preparation method, and its applications. The invention utilizes an electro-induced interfacial polymerization method to construct a tightly adhered in-situ composite hydrogel electrolyte on the electrode surface. Compared to traditional gel electrolytes, due to the enrichment of charged components under an electric field before in-situ polymerization, a stronger interfacial interaction is formed between the electrode and the composite hydrogel electrolyte, thus achieving a highly stable electrode-gel electrolyte interface. The in-situ composite hydrogel electrolyte is rich in functional groups such as amide bonds and carboxyl groups. These groups can effectively induce uniform deposition of zinc ions and inhibit the activity of free water molecules at the interface, thereby effectively suppressing dendrite growth and undesirable side reactions, and effectively improving the cycle stability of the aqueous zinc battery under high zinc utilization. The flexible aqueous zinc battery of this invention can be applied to wearable electronic devices, providing a safe, high-performance, and highly stable power supply solution for next-generation flexible wearable devices.
