Housing part of a battery cell or for a battery cell and method for applying a bursting element on a housing part of a battery cell

摘要

Method for applying a bursting element (4) to a housing part (1) of a battery cell, in particular to a housing part provided for closing a battery cell, comprising the following steps: providing the housing part (1), the housing part (1) - one inside the battery cell facing inside (1c) and an exterior (2) of the battery cell facing the outside (1b) and - in the housing part (1) has a hole (1a) is provided, in the case of an error in which it in the battery cell to a Inadmissible high pressure rise occurs, pressure can escape into the environment, wherein a plate-like bursting element (4) is provided, which is at least slightly larger than the hole (1a), wherein the plate-like bursting element (4) - so from the outside (1b) ago is applied to the hole (1a) so that it completely covers the hole (1a) and - an edge region (4a) of the plate-like bursting element (4) circumferentially m it is connected to an edge region (3) of the housing part (1) which extends around the hole (1a) such that the plate-like bursting element (4) closes the hole (1a) in a fluid-tight manner.
