Document Type and Number:
Japanese Patent JP5928745
Kind Code:
B2
Abstract:
A connection member for secondary batteries to achieve the electrical connection in a battery pack including two or more cylindrical secondary batteries in a physical contact manner is provided, the connection member comprising: an outer circumferential contact part contacting an electrode terminal of a lower battery cell located below the connection member along the outer circumferential region of the electrode terminal of the lower battery cell, such that the outer circumferential contact part can be electrically connected to the electrode terminal of the lower battery cell in a surface contact manner, for minimizing the change of resistance at the contact region against an external force and restraining a possibility that the electrode terminal of the lower battery cell is depressed; and a central contact part contacting the central region of a sidewall of the battery pack for providing an elastic contact force to the entire connection member mounted between the electrode terminals of the battery cells and the sidewall of the battery pack.
