Abstract (en)
[origin: WO2021239442A1] In order to create a cell connector for electrically conductively connecting a first cell terminal of a first electrochemical cell and a second cell terminal of a second electrochemical cell, comprising a first contact region for electrically conductively connecting the cell connector to the first cell terminal, and a second contact region for electrically conductively connecting the cell connector to the second cell terminal, which reduces or delays a thermal propagation from a defective electrochemical cell to a neighbouring electrochemical cell via the cell connector, such that the risk of a thermal runaway of a defective electrochemical cell triggering a thermal runaway of a neighbouring electrochemical cell is reduced, according to the invention, the cell connector has at least one region with a reduced cross-section in the current path between the first contact region and the second contact region, in which the electrically conductive cross-section of the cell connector is reduced by at least one recess.
