Sealed metal-air battery

A sealed metal-air battery using a metal as the negative electrode and an air electrode as the positive electrode, comprising:

• a sealed container for housing the entire metal-air battery or at least the chemical reaction section, the sealed container being a flexible metal container, a flexible metal container coated with a resin film or a flexible resin container;
• Wherein during battery storage, the inside of the sealed container is in an atmospheric state, a vacuum state or an environment filled with an inert gas;
• and when the battery is to be used, at least part of the sealed container is opened to inject electrolytic solution thereinto to begin power generation.

A sealed metal-air battery using a metal as the negative electrode and an air electrode as the positive electrode, comprising:

• a sealed container for housing the entire metal-air battery or at least the chemical reaction section, the sealed container being a rigid metal container or a rigid resin container;
• wherein during battery storage, the inside of the sealed container contains only the solute of the electrolytic solution;
• and when the battery is to be used, at least part of the sealed container is opened to inject a solvent for the electrolytic solution thereinto to begin power generation.
