| 摘要 |
Disclosed herein is a battery module including at least one battery cell constructed in a structure in which an electrode assembly of a cathode/separator/anode structure is mounted in a battery case such that electrode leads of the electrode assembly protrude outside, wherein, when external impacts are directly or indirectly applied to the battery cell, with the result that the electrode leads move toward the electrode assembly of the battery cell, the external impacts are absorbed by the deformation of the electrode leads or the deformation of predetermined regions (electrode lead facing parts) of the module in direct contact with or adjacent to the electrode leads, whereby the occurrence of a short circuit due to the contact between the electrode assembly and the electrode leads is prevented. |
