CONDUCTING BLOCK FOR RESISTANCE WELDING, MANUFACTURING METHOD OF SEALED BATTERY USING THE CONDUCTING BLOCK AND SEALED BATTERY

摘要

PURPOSE: An electroconductive block for resistance welding is provided to realize low resistance between a core expose part and a member for current collection and to enable stable resistance welding through one time welding. CONSTITUTION: An electroconductive block for resistance welding has protrusions on two sides facing metal blocks. Each part between two sides facing metal blocks and lateral sides are chamfered. The chamfered side is a plane. The two sides with protrusions have plane parts which are parallel to each other. The protrusions is formed in a cone or pyramid shapes.
