METHOD OF MECHANICAL CONNECTION OF SECONDARY BATTERY AND CONNECTING MEMBER THEREFORE

摘要

A method for mechanical connection of a secondary battery is provided to prevent the thermal damage and short-circuit possibility of a battery generated in a welding process, to reduce the failure rate and to minimize a terminal connection unit. A method for mechanical connection of a secondary battery comprises the electrical connection of the secondary battery cells by using the predetermined connection elements. The opening(110) for tightening is punched on one or more electrode terminal(100) of the battery cell. The connecting part mechanically combined to the opening for tightening is formed on the connection element.
