发明名称 SECONDARY BATTERY AND METHOD FOR MANUFACTURING THE SAME
摘要 <P>PROBLEM TO BE SOLVED: To prevent a spacer from being damaged by an edge formed at a side edge cut in the process of cutting positive electrodes or negative electrodes. <P>SOLUTION: A negative electrode 12 is carried in an A direction by a carrier device, which is not shown, and the amount that the negative electrode 12 is carried, namely, the length of the negative electrode 12 is measured by a touch roller 51. When the negative electrode 12 is carried in a predetermined distance Lc, the presence or absence of an negative electrode lead 17 is detected by a light emitter 53 and a light receiver 54. Then, the carrying movement of the negative electrode 12 is stopped at a position where a cutter 55 is positioned between the negative electrode leads 17, and the negative electrode 12 is cut by the cutter 55. In this way, the negative electrode 12 is not cut in positions where the negative electrode leads 17 are formed. <P>COPYRIGHT: (C)2012,JPO&INPIT
