Abstract: A battery has a metallic component the inner surface of which is in contact with the battery electrolyte and the outer surface of which is not in contact with the electrolyte. To prevent undesired corrosion a mask is placed over a portion of the inner surface in order to electrochemically inactivate the portion of the inner surface covered by it. Although the metallic component having the mask may be the positive electrode or a terminal, preferably it is the negative electrode and preferably the negative electrode is a metallic foil such as zinc, lead, magnesium, or aluminum or alloys thereof. The outer surface of the metallic component opposite the mask may be exposed to the air. An electrical lead may be connected to the outer surface of the metallic component opposite the mask. Where the mask is applied to the inner surface of an electrode, the mask may contain metal or a metalic compound of a chemical composition compatible with the electrode in order to compensate for the loss in electrochemical activity at the surface of the electrode covered by the mask.

Abstract: A process for improving leakage resistance in a galvanic cell is provided. This is done by making an improved grommet and metal cover. The process comprises swelling a grommet which has been placed tightly around the periphery of a metal cover until the grommet is loose upon the metal cover, forcing a sealant solution between the swollen grommet and metal cover and then shirinking the grommet to substantially its original size to trap the sealant compound between the grommet and metal cover.

Abstract: A sealed primary galvanic cell has a barrier and barrier protecting separator. The barrier protecting separator contains the reaction product of an alkaline earth metal salt and unneutralized carboxypolymethylene. The barrier protecting separator is prepared by applying either of the treating materials in the wet state to a supporting sheet, drying and then applying the second treating material also in the wet state.
