Battery module of improved safety against external impact

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, the battery module including electrode lead facing parts,

• wherein, when external impacts are directly or indirectly applied to the at least one battery cell with the result that the electrode leads move toward the electrode assembly of the at least one battery cell, the external impacts are absorbed by the deformation of the electrode leads or the deformation of the 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, and
• wherein the electrode lead facing parts are constructed in an upward or downward incline structure, or in an easily deformable structure, or are made of an easily deformable material.
