ELECTRICAL CONNECTING MEMBER FOR SECONDARY BATTERY
摘要
Disclosed herein is 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, the connection member including an outer circumferential contact part contacting an electrode terminal of a lower battery cell 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 an electrode terminal of an upper battery cell or 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 respective battery cells or between the electrode terminals of the battery cells and the sidewall of the battery pack.
