Abstract
An air cell of the invention has an air cathode, one surface of which is in contact with an electrolyte and the other surface of which is in contact with air. The air cathode has current collecting grids, a carbon powder, a binder and a metal chelate. The current collecting grids are located at the center of the air cathode. The concentration of the binder in an area of the air cathode which is in contact with the electrolyte beyond the current collecting grids is lower than the concentration of the binder in an area of the air cathode which is in contact with the air.
Claims5
An air cell comprising an air cathode, one surface of which is in contact with an electrolyte and the other surface of which is in contact with air;
- said air cathode having a current collecting grid, a carbon powder, a binder and a metal chelate, said current collecting grid being located at a center of said air cathode, and a concentration of the binder in an area of said air cathode which is in contact with the electrolyte beyond said current collecting grid being lower than a concentration of the binder in an area of said air cathode which is in contact with the air.
