Background technique

[0002] A metal air battery is a special fuel cell that uses metal as a fuel to generate electric energy by redox reaction with oxygen in the air. The metal air battery uses active metal as the anode, which has many advantages such as safety, environmental protection and high breeding density. It has good development and application prospects, and even has high hopes to replace lithium ion power batteries. The raw materials for making metal air batteries are abundant. The metal air batteries that have made research progress mainly include aluminum air batteries, magnesium air batteries, zinc air batteries, lithium air batteries, etc., which are basically in the laboratory stage. Although metal batteries have many advantages, they have many drawbacks.

technical problem

[0003] At present, metal air batteries have the following disadvantages: 1. The voltage of a single metal air battery is 1.6V, and only 1.0V after series connection. This is because the internal electrolyte is connected, which invisibly increases the internal resistance and increases the electric energy. Loss. 2. The precipitation of the resulting metal compound cannot be removed, resulting in polarization of the battery and an increase in internal resistance, which eventually leads to premature failure of the battery. 3. The generated hydrogen is not collected and treated; hydrogen is a flammable and explosive gas that must be managed and controlled. 4. As the battery continues to discharge, the effective composition of the electrolyte decreases, causing the battery to fail prematurely. 5. The oxygen content in the air is only 28%, which restricts the discharge of the metal air battery. 6. The carbon dioxide in the air has a destructive effect on the positive electrode of the air battery. 7. Hydrogen is not used, resulting in waste of resources.
