Abstract
Official abstract text for this publication.
A metal air battery includes: cells, each of which includes a positive electrode, an negative electrode, and an electrolyte layer located between the positive electrode and the negative electrode; and a magnetic field generator configured to form a magnetic field in the cells. The magnetic field generator comprises a permanent magnet attached to one of the positive electrode and the negative electrode.
First claim
Opening claim text (preview).
What is claimed is: 1. A metal air battery comprising: cells, each of which comprising a positive electrode, a negative electrode, and an electrolyte layer disposed between the positive electrode and the negative electrode; and a magnetic field generator configured to apply a magnetic field to an inside of the cells, wherein the magnetic field generator comprises two permanent magnets attached to the positive electrode and the negative electrode, respectively. 2. The metal air battery of claim 1 , wherein the permanent magnet attached to the positive electrode and the permanent magnet attached to the negative electrode are aligned in an attractive force generation direction to generate a magnetic field exerting attractive force in the cells. 3. The metal air battery of claim 1 , wherein the permanent magnet attached to the positive electrode and the permanent magnet attached to the negative electrode are aligned in a repulsive force generation direction to generate a magnetic field exerting repulsive force in the cells. 4. The metal air battery of claim 1 , wherein the two permanent magnets of the magnetic field generator comprise a permanent magnet having an intensity of magnetism of about 50-15,000 G. 5. The metal air battery of claim 1 , wherein the two permanent magnets of the magnetic field generator comprise a permanent magnet having at least one selected from the group consisting of ferrite, magnetite, hematite, maghemite, jacobsite, trevorite, magnesioferrite, pyrrhotite, greigite, feroxyhyte, awaruite, and wairauite-based crystalline structures. 6. The metal air battery of claim 1 , wherein the two permanent magnets of the magnetic field generator comprise neodymium magnets. 7. The metal air battery of claim 1 , wherein the two permanent magnets are respectively disposed at opposing sides of the electrolyte layer to cover the opposing sides of the electrolyte layer.
