Abstract

See full text

A method for applying a rupture element to a housing part of a battery cell, more particularly to a housing part provided for sealing a battery cell, includes the following steps: providing the housing part, wherein the housing part has an inner side facing the interior of the battery cell and an outer side facing the exterior of the battery cell. A hole is provided in the housing part, through which in the event of a malfunction, in which pressure in the battery cell reaches an inadmissably high level, pressure can escape into the surrounding area. A plate-shaped rupture element is provided, which is at least slightly larger than the hole. The plate-shaped rupture element is applied to the hole from the outer side such that it fully covers the hole and an edge region of the plate-shaped rupture element is joined all around to an edge region of the housing part, which extends around the hole, such that the plate-shaped rupture element fluidically seals the hole.
