Abstract

A cylindrical secondary cell 100 is provided comprising a housing 102 with an end surface 103. The cell further comprises an electrode assembly 204 arranged in the housing 102, and a current collector plate 106 connected to an electrode 105 of the electrode assembly 204. The end surface 103 is provided with at least one fracturable portion 124, which is configured to break when the pressure in the housing 102 reaches a threshold value. The current collector plate 106 is provided with at least one flap 202, which is configured to bend toward the end surface when the fracturable portion 124 breaks, such that one or more openings are formed in the current collector plate 106.
