ABSTRACT:
There is disclosed a primary cell for batteries having a sealed, flexible, non-conductive envelope for the active elements of a cell. A subassembly of a combination of the active elements comprises a pouch containing a fluid electrode mass and having a separator sheet included in one wall thereof adapted to be positioned in the envelope with the separator sheet between the enclosed electrode mass and the opposite polarity electrode. The electrode mass-separator subassembly is made up of sheets of flexible material positioned on opposite faces of the electrode mass and bonded together as by face-to-face fusion of the materials of the sheets around their superimposed perimeters to enclose the electrode mass.
