Abstract: An alkaline primary battery has at least two cells. The cells are of the type where the anode material (zinc) is in the form of a powder suspended in a gel and is located in the central portion of the cell. The anode current collector for the second cell is made as an integral portion of the first cell and takes the form of a metal rod dependent from the base of the first cell. The cells are built without anode current collectors. In the assembly of a battery from such cells, the anode current collector attached to a first cell is forced through the cover of a second cell and embeds itself in the anode structure of the second cell. The anode collector for the first cell is in the form of a loose metal rod and is similarly forced through the cover and into the anode structure of the cell. The end cell opposite to the first cell is similar to the other cells except that it does not have a current collector attached to its base.

Abstract: The method, which provides liquid-impervious seals around opposed positive and negative battery electrodes in a collation of battery layers, concerns the need to apply energy around the opposed electrodes by some means other than and for a longer time period than the conventional pair of pressure rolls which have previously been used to seal moving battery layers. With this invention the seals are made by platens which either travel along with the moving collation during the sealing step or which are brought into contact with an increment of the collation which is temporarily stopped.
