Embodiment 1

[0027] This embodiment relates to a method for preparing a flexible zinc-air battery with waste cloth as a substrate, and the steps are as follows:

[0028] Step 1. Put the cleaned carbon film of 2cm*5cm into an aqueous solution of cobalt nitrate with a concentration of 0.01mol / L for electrodeposition. The temperature is controlled at 20~35°C, the electrodeposition voltage is 1V, take it out after 10min, and rinse with water Clean and dry, put into a heating furnace, heat treatment at 200°C for 2 hours, and prepare a cobalt tetraoxide / carbon film;

[0029] Step 2. Preparation of colloidal electrolyte: Add a certain amount of polyvinyl alcohol powder into a solution of 0.1 g / ml and 10 ml of potassium hydroxide, heat and stir, and then solidify to form a colloidal electrolyte.

[0030] Step 3. Soak 2cm*5cm cloth in a stannous chloride solution with a concentration of 10g / L and 40mL / L and 36.5% hydrochloric acid for 5 minutes. After rinsing, put the cloth in a concentration of 0....

Abstract

The invention provides a preparation method of a flexible zinc-air battery taking waste cloth as a matrix. The method comprises the following steps: cobalt hydroxide is electrodeposited on a carbon film and subjected to heat treatment to form cobaltosic oxide serving as a positive electrode, zinc is plated on a chemical copper plating waste fabric to serve as a negative electrode, colloid of PVA and potassium hydroxide serves as a diaphragm and an electrolyte, then plastic packaging is conducted through a plastic film, and the flexible battery is obtained. Compared with the prior art, the invention has the following beneficial effects: 1, colloid of PVA and potassium hydroxide is used as a diaphragm and an electrolyte, and a liquid electrolyte is not used, so that liquid leakage can be effectively prevented, the colloid can be tightly attached to the rough surface of the carbon cloth positive electrode, and the conductive efficiency is improved; 2, a special alkaline galvanizing solution galvanizing formula is used for electrogalvanizing, so that the galvanizing quality is greatly improved; 3, the negative electrode raw material is waste fabric, so that waste of wastes can be avoided, and an environment-friendly effect is achieved.

Description

technical field [0001] The invention relates to a preparation method of a flexible zinc-air battery using waste cloth as a substrate, and belongs to the technical field of energy devices. Background technique [0002] With the change of lifestyle and the development of electronic technology, flexible and wearable electronic devices are entering people's sight. Traditional batteries cannot be bent, and cannot meet the overall thin and soft requirements of electronic products. The development of flexible energy storage devices matched with flexible wearable electronics plays a vital role in the development of flexible wearable electronics. [0003] At present, some small flexible batteries with a certain degree of bending have appeared on the market, such as flexible neutral zinc-manganese batteries, soft-pack lithium batteries, and so on. These batteries all have the defect of low energy density. However, the theoretical energy density of zinc-air batteries can reach 1084 ...
