Abstract:
1. A battery cell configured such that at least one electrode assembly of a structure having a cathode, an anode, and a separator interposed between the cathode and the anode is mounted in a battery case, at least one heat dissipation member to dissipate heat generated in the electrode assembly during charge and discharge of the battery cell or upon occurrence of a short circuit is disposed in the electrode assembly and/or is in contact with an outer surface of the electrode assembly, and a portion of the heat dissipation member is exposed outward from the electrode assembly, wherein at least one side end of the heat dissipation member is in surface-to-surface contact with the inside of the battery case, the at least one side end of the heat dissipation member exposed outward from the electrode assembly being bent, while the portion of the heat dissipation member exposed outward from the electrode assembly is not exposed outward from the battery case.
