Abstract: A galvanic cell and battery sealant is described in which the sealant between container and cover has a permanent foam structure. The sealant may be any of the available sealant materials known to the art, having the properties of adherence, foamability, permanence and inertness to the battery electrolyte. The foamed sealant is equally suitable for batteries closed by sealant alone without a cover. Typical sealant materials are foamed epoxy, foamed phenolic, foamed furan and foamed polyester. The density of the foamed material may be chosen to be between 2 and 50 lbs. per cubic ft. A method for sealing galvanic batteries and cells also form a part of the invention. The foam sealant is readily removeable for battery repair.
