Abstract
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.
Claims6
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, and
- wherein a contact angle between the liquid electrolyte and a surface of the separator that faces the negative electrode is smaller than a contact angle between the liquid electrolyte and a surface of the separator that faces the air electrode.
