PURPOSE:To maintain the higher discharge voltage by pressing and fixing an amalgamated zinc plate which is a negative electrode active material on the inner bottom of a negative electrode can and filling the aqueous solution of calcium hydroxide and potassium hydroxide with the specific grain size and density in the dry state. CONSTITUTION:A negative electrode zinc plate 1 with the thickness of 1.5mm and the diameter of 8mm is pressed to the inner bottom of a negative electrode can 4, its total weight is set to 537mg, the amalgamated mercury quantity is set to 2mg. Ca(OH)2 coarse grains 610mg with the density of 1.14g/cc and 35-150 mesh are prepared, a KOH aqueous solution 115mul with the concentration of 30% is added and mixed as an electrolyte and filled in the negative electrode can 4. A positive electrode can 5, a gasket 6, a separator 7 and a positive electrode 8 are arranged by the ordinary method. The mercury quantity used is reduced, and an air cell maintaining the high discharge voltage can be obtained according to this constitution. |
