METAL-AIR BATTERY

摘要

Problem to be Solved;The present invention reduces decrease in discharge voltage of a metal-air battery and reduces the size of the battery.;Solution;A positive electrode includes plural plate-shaped pieces of positive electrode material 32 having a porosity structure or fibrous structure and containing an electrically conductive material and the positive electrode material 32 is electrically connected with a positive electrode collector 31. Surfaces of the plural pieces of the positive electrode material 32 are coated with a catalyst, the pieces of the positive electrode material 32 are stacked with the catalyst-coated surfaces facing each other, and a direction in which the pieces of the positive electrode material 32 are stacked is arranged to be parallel to a direction in which the positive electrode and negative electrode are stacked.
