Abstract

The invention discloses a zinc air battery. The zinc air battery comprises a first case, a second case and a battery main body, wherein the first case is provided with a hollow cavity for accommodating the battery main body, the second case is connected with the first case in a sealing manner to seal the battery main body; an opening part is formed in at least one side surface of the first case and is provided with a semipermeable membrane, and a gas molecule can permeate the semipermeable membrane, but a water molecule cannot permeate the semipermeable membrane. The provided zinc air battery is provided with the semipermeable membrane, the semipermeable membrane allows the gas molecule to get through but stops the water molecule, water in the first case is prevented from permeating through the first case, or the water molecule in the air is prevented from entering the first case, so that the safety performance of the zinc air battery and the quality are improved; and the zinc air battery is simple in structure, convenient in installation and convenient in use.

Description

technical field [0001] The invention relates to the technical field of new energy batteries, in particular to a zinc-air battery and a battery pack. Background technique [0002] An air battery is a chemical power source in which oxygen in the air is used as the positive electrode active material and metal is used as the negative electrode active material. Under the catalysis of the catalyst, a chemical reaction occurs to generate electrical energy. Among them, zinc-air batteries have the best performance, and also have the advantages of low cost, stable discharge voltage, and environmental protection, so they are widely used in various portable mobile power sources and are deeply loved by users. [0003] At present, the main structure of the air battery is to fuse the negative electrode metal zinc and the electrolyte together, which requires good sealing and high cost, or there are vent holes on the surface of the air battery shell, and the air entering is limited, making t...
