Embodiment 1

[0046] This embodiment relates to a method for preparing a stretchable zinc-air battery array, the steps of which are as follows:

[0047] Preparation of a copper wire circuit with a serpentine pattern embedded in the silicone rubber film: bend a copper wire with a diameter of 0.02 mm into a serpentine pattern with a width of 5 mm, and then weave the copper wire with a serpentine pattern into a circuit. Put the copper wire circuit in the mold, pour the commercial Ecoflex silicone rubber A and B liquid mixed evenly at 1:1, and let it stand at 60°C for 1 hour. The serpentine copper wire is fixed in the silicone rubber film and exposed to the silicone rubber. The copper wires on the outside of the membrane are woven into circuit contacts, and the serpentine copper wire circuit is embedded in the silicone rubber membrane. Take two pieces respectively as the first silicon rubber film layer and the second silicon rubber film layer.

Abstract

The invention belongs to the field of intelligent energy storage devices, in particular to a stretchable zinc air battery array and a preparation method thereof. The preparation method comprises the steps of: firstly, embedding a snakelike line copper wire circuit in a silicone rubber mold; secondly, binding a zinc foil piece and a modified carbon cloth to specific positions of the snakelike linecopper wire circuit to form an array and serve as a negative electrode and a positive electrode of a battery respectively; thirdly, separating the zinc foil piece and the modified carbon cloth by means of a polymer electrolyte film; and finally sealing edges to obtain the stretchable zinc air battery array. The stretchable zinc air battery array is rechargeable, has good bendability and stretchability, and stably discharges during the dynamic stretching and bending process. The battery array can be sewn on clothes, and thus has a good application prospect in the field of wearable equipment.

Description

technical field [0001] The invention relates to a preparation method of a stretchable zinc-air battery array, belonging to the technical field of intelligent energy storage devices. Background technique [0002] At present, stretchable and flexible electronic devices are suitable for deformation and curved surface environments such as human body, robot, and braided fabrics, and have received extensive attention. Stretchable and flexible energy storage devices such as lithium-ion batteries, alkaline batteries, and supercapacitors have been investigated. Zinc-air battery is a battery with higher energy density, which is suitable for power supply for a long time, and is economical, environmentally friendly and safe. [0003] The stretchable flexible zinc-air batteries that have been developed can only meet simple and small-scale bending and stretching deformations. When subjected to large stretching rates, it is easy to cause separation of electrodes and current collectors, re...
