CID Method of manufacturing CID assembly for a secondary battery and CID assembly thereof

摘要

The present invention discloses a method of manufacturing a CID assembly for a secondary battery and an assembly thereof. A method of manufacturing a CID assembly and an assembly thereof according to the present invention includes a step of preparing a cap-down adhering material by thermally fusing one surface of an adhesive insulating member to a cap-down portion of a plate- A step S2 of manufacturing a thin safety band attaching member by aligning and fusing the projections of the thin safety band having a protrusion at the center in the form of a metal plate on the other side of the adhesive insulating member of the cap down attaching member, And a step S3 of manufacturing the CID module by attaching the protrusion and the subplate by ultrasonic welding. In this case, the structure retained by the frictional force only by fitting between the parts of the cap assembly is improved, And the 'Z' bending structure is removed to fundamentally reduce the thickness to increase structural stability and capacity of the secondary cell Is effective.
