ELECTRICAL CONNECTING MEMBER FOR BATTERY CELL BASED ON PHYSICAL CONTACT MANNER

摘要

PURPOSE: A connection member for a battery cell is provided to stably at least two secondary battery cells without soldering and welding, to maintain a stable connection state in long-term use, and to improve the safety to external force. CONSTITUTION: A connection member(100) for a battery cell comprises: main connection parts(110) contacting with an electrode terminal of a lower battery cell near a outer circumference of the connection member corresponding to the outer shape of the electrode terminal; elastic protrusion parts(120) upwardly tapered in a middle axis direction on a basis of the main connection parts; central connection parts(130) contacting the electrode terminal of the top battery cell; and side extended parts(150) where terminal parts for connecting external circuit at one side of the elastic protrusion parts.
