摘要： A zinc/air button cell having an adhesive sealant applied to a portion of the inside surface of the cell's cathode casing. The adhesive sealant can be applied to the inside surface of a recessed annular step surrounding the cell's positive terminal on the cathode casing. The adhesive is preferably applied in a pattern which conforms to the shape of the annular recessed step. An electrolyte barrier sheet, preferably of Teflon, can be applied to the adhesive pattern on the inside surface of said recessed step, preferably so that the adhesive bonds the edge of the barrier sheet to the step. The adhesive prevents electrolyte from leaking from the cell. The adhesive is applied preferably by preparing a plate having a desired pattern etched thereon, filling the etching in the plate with an adhesive mixture, applying a silicon pad to the etching to transfer the adhesive pattern to the pad, then applying the pad to the inside surface of the cathode casing step to transfer the adhesive pattern thereto. The adhesive is preferably a solvent based mixture comprising a polyamide.

摘要： An end cap assembly for a primary lithium cell is disclosed. The end cap has a principal application in closing and sealing a primary lithium cell having wound electrodes. The cell may typically have an anode comprising lithium and a cathode comprising iron disulfide (FeS2). The end cap assembly has a metal cathode contact cup therein having a closed end and opposing open end with integral side walls therebetween. The cathode contact cup is electrically connected to the cathode and is within the electrical pathway between the cathode and terminal end cap. The cathode contact cup has one or more grooves formed at the closed end thereof resulting in thinned or rupturable portions of remaining metal underlying said grooves. The thin or rupturable remaining metal portions are exposed directly to gas within the cell interior and are designed to rupture when gas within the cell builds to a predetermined level.
