Abstract (en)
[origin: WO2021113891A1] The invention relates to a device for breaking the electrical connection to a battery cell (1) in the event of outgassing, in which the cell pole (3) on the outgassing valve side is connected to an electrical contact point (5) at a connection point (4) via a connecting lead (2) which forms a fuse. In order to create such a device which, requiring few components and having a compact design, enables a reliable electrical and thermal protection of neighbouring cells of an outgassing battery cell against overloading and prevents the spread of a thermal runaway, a spacer (6) which electrically isolates the connection point (4) from the contact point (5) in the event of outgassing and retains the cell pole (3) is provided between the connection point (4) and the contact point (5).
