Abstract: A method of manufacturing a battery consisting of one or several cells piled on each other and integrally connected along their circumferences. Each cell comprises a zinc anode, an alkaline electrolyte, a cathode of mercuric oxide, silver oxide or manganese dioxide or a mixture thereof, and a cell casing in the form of a plastic cup. A terminal plate is located on both sides of the plastic cup, said terminal plates abutting a substantial area of the outer and the inner side of the bottom, whereby at least one terminal plate comprises at least one projecting knob extending through a comparatively small aperture in the bottom of the cup and being connected by spot welding to the second terminal plate in such a manner that the plates sandwich and under pressure abut the material in the bottom of the cup. Prior to the spot welding a mass is added in the form of bitumen to the aperture in the bottom of the cup, the sealing mass being pressed sideways during the spot welding.

Abstract: An electrical battery with a non-aqueous electrolyte comprising thionyl chloride or sulfuryl chloride and a metal salt dissolved therein and with an anode of a metal from group 1 or 2 in the Periodic Table or alloys of these has reduced delays action (D.A.) when the electrolyte contains a SO.sub.3 compound.

Abstract: A battery comprises a single flat cell with a cell casing in the form of a plastic cup, or several cells piled on each other, whereby the plastic cups are integrally connected along the circumference. Each plastic cup comprises a terminal plate located both on the inner side and on the outer side of the bottom of each cup. One of these terminal plates comprises a projecting knob extending through an aperture in the bottom of the cup, and is connected to the other terminal plate in such a manner that the plates squeeze tightly about the bottom of the cup and abut the upper and lower surfaces thereof by a permanent pressure. As a result, a durable, efficient sealing against electrolyte leakage at the terminal passage in the bottom of each plastic cup is provided.
