Title:
METAL-AIR BATTERY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/199600
Kind Code:
A1
Abstract:
This metal-air battery system comprises: an entrance chamber through which an electrolyte flows in; an exit chamber through which the electrolyte flows out; a hollow outside electrode having an internal space that allows the entrance chamber and the exit chamber to be in communication with each other; and an inside electrode provided so as to be inserted into the internal space concentrically with the outside electrode. One of the outside electrode and the inside electrode is a negative electrode containing a metal, and the other thereof is a porous positive electrode into which oxygen can be diffused. A flow path through which the electrolyte flows from the entrance chamber to the exit chamber is formed between the outside electrode and the inside electrode. The cross-sectional area of the flow path is configured so as to decrease from the entrance chamber side to the exit chamber side.
