The invention relates to the field of energy storage, particularly to a method for manufacturing a tensile high-performance Zn-MnO2 battery. The method specifically comprises the following steps: firstly, treating commercial sponge, and performing PDDA (Poly Diallyldimethyl Ammonium Chloride) surface wrapping modification on the commercial sponge so as to change surface electric properties of thecommercial sponge; wrapping the surface of the sponge with a layer of a conductive network under the action of electrostatic force, functionalizing the sponge wrapped with the conductive network, manufacturing electrodes of a battery by using soaking and electric deposition methods, finally packaging the battery, and testing properties of the battery. The method has the characteristics of low cost, simple process and excellent product property, and has wide application prospects in fields such as wearable equipment, intelligent equipment and energy storage.
