ELECTRODE TERMINAL CONNECTION BODY, MANUFACTURING METHOD OF THE SAME AND ELECTRIC STORAGE SYSTEM

摘要

A manufacturing method for an electrode terminal connection body includes applying a press processing to a plate member formed of the same kind of metal as a metal of a positive electrode terminal so as to form a mounting hole, slicing a covered metal rod more thickly than the plate member so as to form a covered metal member, the covered metal rod being configured to include an interposing layer formed of a metal that has an ionization tendency between the metal of the positive electrode terminal and the metal of a negative electrode terminal in the outer periphery of a metal rod formed of the same kind of metal as a metal of the negative electrode terminal and to have a diameter smaller than the mounting hole, and inserting the covered metal member into the inside of the mounting hole and simultaneously crushing the covered metal member.

1. A manufacturing method for an electrode terminal connection body configured to electrically connect a positive electrode terminal and a negative electrode terminal that are formed of mutually different kinds of metals, comprising:
applying a press processing to a plate member formed of the same kind of metal as a metal of the positive electrode terminal so as to form a mounting hole; slicing a covered metal rod more thickly than the plate member so as to form a covered metal member, the covered metal rod being configured to include an interposing layer formed of a metal that has an ionization tendency between the metal of the positive electrode terminal and the metal of the negative electrode terminal in the outer periphery of a metal rod formed of the same kind of metal as a metal of the negative electrode terminal and to have a diameter smaller than the mounting hole; and inserting the covered metal member into the inside of the mounting hole and simultaneously crushing the covered metal member in the inside of the mounting hole so as to join the plate member and the covered metal member by using the interposing layer as a boundary while expanding the mounting hole.
