Connective structure between a battery cell and a connecting bar of a battery pack

摘要

A battery pack having an improved a coupling force between a battery cell and a connecting bar of a connecting structure. The connecting structure includes at least one battery cell, a connecting bar electrically connected to the battery cell, a welding region formed at a connecting area of the battery cell and the connecting bar, and an anisotropic conductive film formed at the outer periphery of the welding region and connecting the battery cell and the connecting bar to each other.
