The invention belongs to the field of energy storage materials, and relates to an aqueous zinc ion battery, in particular to a gel electrolyte that effectively inhibits zinc dendrites, and a preparation method and application thereof. By introducing nano-sized hectorite into the polymer hydrogel and polymerizing it into a gel electrolyte, the mechanical strength of the composite gel electrolyte can be effectively improved by utilizing the characteristic that hectorite attracts long polymer chains; The electrification properties in aqueous systems, leading to uniform deposition of zinc ions. At the same time, the present invention also provides the above-mentioned preparation method of the gel electrolyte that effectively inhibits zinc dendrites, the method is simple in process, suitable for industrialization, and the prepared gel electrolyte can effectively inhibit zinc dendrites and side reactions; the gel electrolyte and MnO 2 The flexible quasi-solid ZIB composed of @8%rGO cathode and electrodeposited Zn@carbon cloth anode can stably power electronic displays in harsh environments of shearing and bending. |
