PURPOSE:To contrive to stabilize and improve the performance of a cell by injecting the electrolyte to the positive electrode compound after placing the said positive electrode compound made by adding and mixing hydrophilic filler to a mixed powder of positive electrode active material and electro-conductive material onto the bottom plate of the positive electrode can from the aperture of the positive electrode can and forming by pressure in the positive electrode can. CONSTITUTION:The positive electrode compound 1 made by adding and mixing the cotton linter of 0.5wt% of the mixed powder of manganese dioxide (positive electrode active material) and scaled graphite (electro-conductive material) to the said mixed powder and pre-formed is placed on the bottom plate of the positive electrode can by moving towards the arrow I from the aperture 2a of the positive electrode can 2. Then a pressure of 1-1.5t/cm<2> is applied to the surface of the positive electrode compound 1 from the direction of the arrow P. After the forming by pressure is completed, 46ml of the electrolyte consisting of 40% aqueous solution of KOH are injected, and after this electrolyte is absorbed in the compound completely, the separator 3, gellike negative electrode 4, negative electrode terminal 5 and packing 6 for aperture sealing are assembled by means of the well known method to construct the cell. |
