BATTERY CELL WITH A RAPIDLY DISCHARGING UNIT AND METHOD FOR RAPID DISCHARGING OF SUCH A BATTERY CELL

摘要

pA battery cell (10) with two battery cell terminals (11, 12) which are contactable from inside and/or outside the battery cell (10), and an electrochemical part (20) comprising at least one separator. Upon the achievement of a predefined temperature, the at least one separator is at least partially impermeable to ions which can be generated in the electrochemical part (20). The battery cell (10) has a rapid discharge unit (30), which is connectable between the battery cell terminals (11, 12) and which, in a switched-in and consequently activated state, has a predefined resistance value. The predefined resistance value is selected such that, with the rapid discharge unit (30) switched-in, the at least one separator achieves the predefined temperature./p[US2017133872A1]
