Title:
ELECTRODE, METAL-AIR BATTERY, AND ELECTRODE MANUFACTURING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/112335
Kind Code:
A1
Abstract:
A metal-air battery (1) includes a negative electrode (3), a positive electrode (2), and an electrolyte layer (4) disposed between the negative electrode (3) and the positive electrode (2). The negative electrode (3) includes a base member (31) which has a coiled shape and is formed of a conductive material and a deposited metal layer (32) in powder or particle state, which is formed on a surface of the base member (31) by electrolytic deposition. The electrolyte layer (4) contains an alkaline aqueous solution which contains the same metal as the deposited metal layer (32), and the positive electrode (2) has a tubular shape which is concentric with the negative electrode (3) having the coiled shape and surrounds the negative electrode (3). In this metal-air battery (1), it is possible to suppress occurrence of dendrites in the negative electrode (3).
