Gel-based button type zinc-air battery

Abstract

The invention discloses a gel-based button type zinc-air battery. The preparation method comprises the following steps: uniformly mixing an acrylamide monomer, an ether polymer and graphene oxide according to a certain proportion, and polymerizing in a constant-temperature box to prepare a gelatinous substance; dissolving the strongly alkaline solid particles in a proper amount of deionized water to prepare the strongly alkaline electrolyte; soaking the gel polymer formed by polymerization in a strong alkaline electrolyte to obtain the gel polymer electrolyte; and assembling a zinc foil, a gel polymer electrolyte and an air electrode into a three-layer structure, and then packaging the three-layer structure in a metal shell to be assembled into the button type zinc-air battery. The ether polymer and the graphene oxide are added into the acrylamide, so that the performance of the gel electrolyte is optimized; and in addition, due to the use of the gel electrolyte, the defects of electrolyte leakage and easy corrosion of a metal shell of a traditional button battery are overcome, and the charge-discharge performance and the cycle stability of the battery are improved. The battery is simple in structure and convenient to prepare, and has great development potential in the field of button batteries.

Description

technical field [0001] The invention belongs to the field of metal-air battery energy utilization, and in particular relates to a gel-based button-type zinc-air battery. Background technique [0002] The development of the country and the progress of the society have brought new challenges to the global energy requirements. The demand for energy is rising, fossil energy is exhausted, and world pollution is intensifying. In this context, the country implements the national policy of saving resources and protecting the environment. Innovation has become a new development direction, and the development of green, environmentally friendly and sustainable clean energy has become a new trend, driving the development of battery energy storage technology. [0003] Although the traditional battery technology is relatively mature, but the cost is relatively high, especially there are very serious pollution problems, which do not meet the development requirements of energy conservation ...

AI Technical Summary

Problems solved by technology

[0005] (1) The traditional button-type zinc-air battery is a disposable battery without charging performance. The internal electrolyte material is usually a high-concentration strong alkaline mixture, which is highly corrosive

[0006] (2) There is a risk of electrolyte leakage. Once the electrolyte leaks, it will quickly corrode the battery components, causing irreparable damage, resulting in a sharp deterioration in battery performance or even failure

[0007] The above factors have greatly limited the development and practical application of button-type zinc-air batteries.
