<P>PROBLEM TO BE SOLVED: To accurately complete assembly work of a battery even if dimensional error occurs between a core and a battery can, simplify a member and structure, make electrical connection direct, and reduce the internal resistance of the battery. <P>SOLUTION: In the conductive connection structure of a lithium ion secondary battery core installing a conductive connection piece at the end of the core and electrically connecting the core to a positive electrode lead terminal and a negative electrode lead terminal of the battery can with the conductive connecting piece, the core is composed of a core rod, a rolled electrode, and a bundling member, the rolled electrode is formed by laminating at least one positive electrode layer, at least one separator, and at least one negative electrode layer in order and winding them onto the core rod, and the conductive connection piece is composed of at least one fixing pin and at least one conductive pressing piece. <P>COPYRIGHT: (C)2008,JPO&INPIT |
