Abstract
Official abstract text for this publication.
A metal-air battery with a high discharge capacity is provided. Discharge capacity can be increased by a metal-air battery that includes an air electrode, a negative electrode and an electrolyte layer, where the electrolyte layer includes a porous separator, and a liquid electrolyte infiltrated in the separator, and a contact angle between the liquid electrolyte and a negative electrode side-face of the separator is smaller than that between the liquid electrolyte and an air electrode side-face of the separator.
First claim
Opening claim text (preview).
The invention claimed is: 1. A metal-air battery comprising: an air electrode, a negative electrode, and an electrolyte layer disposed between the air and negative electrodes, wherein the electrolyte layer comprises a separator having a porous structure, and a liquid electrolyte infiltrated in the separator, a contact angle between the liquid electrolyte and a surface of the separator that faces the negative electrode is within a range of 30 degrees to 50 degrees, and a contact angle between the liquid electrolyte and a surface of the separator that faces the air electrode is within a range of 60 degrees to 80 degrees. 2. The metal-air battery according to claim 1 , wherein the separator is a laminate of two or more porous layers having different contact angles to the liquid electrolyte, and the separator has a structure that the porous layer having a contact angle which is within a range of 30 degrees to 50 degrees to the liquid electrolyte is disposed at the surface that faces the negative electrode and the porous layer having a contact angle which is within a range of 60 degrees to 80 degrees to the liquid electrolyte is disposed at the surface that faces the air electrode.
