Abstract
A battery cell includes: an electrode assembly; a case configured to accommodate the electrode assembly; a first lead electrode electrically connected to at least one of two electrode tabs of the electrode assembly; a conductive polymer including one surface that is in contact with one surface of the first lead electrode; and a second lead electrode including one surface that is in contact with the other surface of the conductive polymer, in which when a gap between the first lead electrode and the second lead electrode increases, resistance between the first lead electrode and the second lead electrode increases.
