Title:
SEALED METAL-AIR BATTERY
Document Type and Number:
WIPO Patent Application WO/2023/228428
Kind Code:
A1
Abstract:
The purpose of the present invention is to realize a portable disaster prevention battery obtained by packaging, in a sealed container, a metal-air battery having high energy density. The sealed metal-air battery according to the present invention is a metal-air battery that uses metal in a negative electrode and an air electrode in a positive electrode and is provided with a sealed container accommodating the entire metal-air battery or at least a chemically reacting portion of the metal-air battery. The sealed container is a rigid metal container or a rigid resin container, and the inside of the sealed container during storage of the battery is in an atmospheric state or a vacuum state, or is an environment filled with an inert gas. During battery use, a portion of the sealed container is opened and an electrolyte is injected so as to begin power generation. Alternatively, the inside of the sealed container during storage of the battery is in a state in which only the solute of the electrolyte is accommodated therein, and during battery use, a portion of the sealed container is opened and the solvent of the electrolyte is injected so as to begin power generation.
