Title:
電池用電極及びその製造方法
Document Type and Number:
Japanese Patent JP5008787
Kind Code:
B2
Abstract:
A workpiece (11), in which a lead is laid on top of a three-dimensional porous metal body, is placed between an ultrasonic horn (2) and an anvil (3) with a lead portion facing the ultrasonic horn (2). A support (7) is raised so that the lead portion of the workpiece (11) is pressed between the ultrasonic horn (2) and the anvil (3). While being rotated around a central shaft (4) with a motor (17), the ultrasonic horn (2) vibrates at a frequency of 20 kHz in the shaft direction. Thus, the workpiece (11) is advanced continuously, so that the lead is bonded ultrasonically to the three-dimensional porous metal body (i.e., metal-to-metal bonding is established). It is possible to provide a battery electrode that can be produced continuously at a lower running cost, reduce the faulty welding with a current collecting plate, and prevent short-circuits.
