Abstract

PURPOSE:To improve the shelf life of a cell by laminating cells after air is removed from the cells by evacuating the cells for a laminated dry cell the main electrolyte of which is zinc chloride. CONSTITUTION:When a dry cell the main electrolyte of which is zinc chloride is fabricated, cells are laminated after air in the cells is removed by evacuating the cells. For example, 21 parts by weight of a 80:15 manganese dioxide-acetylene black mixture is wetted with 9pts.wt. of a 28% by weight of zinc chloride, 5% by weight of ammonium chloride, and 72% by weight of water mixed electrolyte to prepare a positive compound 4. The compound is contained in a carbon-zinc bonding electrode 3 on the periphery of which the periphery of a heat shrinking tube 6 is adhered spacing with a separator 5 to form a cell, the cells are stood in an evacuated chamber of lower than 200mm.Hg for 20min to remove air, and the cells are laminated to form a laminated dry cell.
