Method for producing coin-shaped lithium electrode assembly and apparatus for cutting lithium metal rod for coin-shaped lithium electrode

摘要

PROBLEM TO BE SOLVED: To manufacture a highly reliable lithium electrode medium with an excellent yield by cutting an Li bar-shaped metallic body end part installed in an inserting groove on an under surface of a fixed type cutting edge by a movable edge having a sandwiching head having a necessary sandwiching width, and transferring and press- fitting this Li metallic piece to a selaing body inside bottom surface. SOLUTION: A tip part of an Li metallic bar-shaped body 10 having a width L1 inserted into an inerting port on an under surface of a fixed type cutting edge 9 is sandwiched by clamping bodies 11a and 11b whose width L2 at closing time of a clamping head 11 integrally formed with a pedestal 12 having a movable edge 12a is larger by 0.2 to 0.44mm than the width L1 , and is cut by the edge 12a rising through a driving control mechanism 14. In this case, a lateral movement of the base stand 12 and opening-closing of the sandwiching parts 11a and 11b are controlled by a driving control mechanism 13, and it is sandwiched in a right position by a right cap, and an Li metallic piece to which cutting chips or the like are not stuck is obatained, and is transferred and press-fitted to a sealing body bottom surface through the head 11. Therefore, a highly reliable lithium electrode body structure is manufactured with an excellent yield.
