Problems solved by technology

The manufacturing process of these casing materials for battery packaging is mature, but these casing materials will increase the weight of the entire battery and increase the price, especially casing packaging materials such as plastics, which have poor environmental friendliness
The positive and negative electrode materials of magnesium-based metal-air batteries are environmentally friendly materials without environmental pollution. However, the plastic packaged in the shell affects the environmental protection advantages of battery materials. Therefore, it is necessary to improve the shell packaging materials and Its packaging method is improved and promoted

Abstract

The invention discloses a preparation method of a magnesium-based metal air battery. The preparation method comprises the following steps of 1, preparing a positive electrode catalytic material, 2, preparing a battery shell, 3, mounting a positive plate, 4, packaging a battery shell, and 5, assembling the single batteries. The invention also discloses the magnesium-based metal air single battery and the magnesium-based metal air battery which are manufactured by using the preparation method. The composite paper and the magnesium-based metal air battery positive electrode catalytic material are subjected to hot gluing, so that firm packaging can be realized, and the sealing problems of electrolyte leakage and the like are avoided; the composite paper is light in weight, high in strength and good in toughness, so that the packaging weight can be greatly reduced, and enough compression resistance, falling resistance and impact resistance of the battery can be ensured; paper is adopted for packaging, batch and large-scale production is suitable, the production efficiency is obviously improved, and full-automatic heat sealing, folding and liquid injection can be achieved.
