Abstract

The invention relates to the technical field of batteries, in particular to a zinc-air battery and a preparation method thereof. The zinc-air battery comprises a positive electrode, a negative electrode, and an electrolyte, wherein the positive electrode and the negative electrode are in a solid state. The preparation method comprises the following steps: firstly stacking the manufactured positiveelectrode and negative electrode by a laminating way, and separating the positive electrode from the negative electrode by dustless diaphragm paper; then wrapping with a molding PP shell, melting thethree sides by means of hot melt, injecting into a conductive liquid, and finally bonding the edge to obtain the zinc-air battery. The battery produced by the invention not only has low cost, large energy storage and environmental protection, but also greatly reduces the operation difficulty, the preparation process is simple, the operation cost is low, the process is easy to control, the yield is high, and the production efficiency is obviously improved.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a zinc-air battery and a preparation method thereof. Background technique [0002] Zinc-air battery, green and environmental protection is the highlight, and is known as an environmentally friendly new energy source in the 21st century. Since the zinc-air battery does not use heavy and toxic heavy metals such as lead, mercury, and cadmium, it has less pollution to the environment, and at the same time, there is no danger of explosion, and it is safe and reliable. Secondly, the cost is low and the energy storage is large. The raw materials are mainly oxygen in the air and cheap zinc, so the materials are easy to get. And its capacity is 3-10 times higher than other batteries. A single 300 Ah cylindrical zinc-air battery weighs only 0.75kg, while the same lead-acid battery weighs more than 8kg. Compared with the current mainstream lithium car batteries, data show that a 180 k...
