Zinc ion battery

Technical Field

The utility model relates to a power, concretely relates to utilize device of zinc air reaction electricity generation.

Background

Mercury-free, tin-free, cadmium-free and lead-free batteries and high-alkaline zinc batteries are development directions of the battery industry in China.

The zinc-manganese battery generally adopted in our daily life is an alkaline battery, which uses natural materials with high impurity content, and in order to prevent the corrosion of zinc in electrolyte, a corrosion inhibitor must be added into a battery isolation layer, the most commonly used corrosion inhibitor is mercury chloride, which is usually added into paste of a paste battery or coated paper of a paperboard battery, and the mercury also becomes a main harmful element in the battery for polluting the environment.

The zinc-air cell is an alkaline cell, which consists of an air electrode, a shell, alkali liquor and a metal zinc cathode. Its features derive from the air electrode. The air electrode depolarizer (active material) is oxygen in the air, so as long as the air can be continuously supplied to the battery, the air electrode can continuously work, which is inexhaustible, and thus the positive electrode capacity is unlimited. The positive electrode does not contain active substances, the volume can be infinitely small, and the weight of the positive electrode is lighter than that of the common battery positive electrode. The specific energy is 200-270wh/kg which is 4-5 times of that of the zinc-manganese dry cell. This battery also has its disadvantages: firstly, the porosity of the positive electrode is not very large, the working current is not large enough, and secondly, the charging cannot be carried out, and the cost is higher.
