<p><P>PROBLEM TO BE SOLVED: To solve such a problem that when a notch is provided in an uncoated part in order to equalize the length of a coated part and the length of the uncoated part after roll press, the shape and the size of a terminal to be connected with an external circuit are limited. <P>SOLUTION: In the press method of an electrode foil 10 for a battery having a coated part 1 where a long current collector foil is coated continuously in the longitudinal direction with an electrode active material, and an uncoated part 2 where a long current collector foil is not coated continuously in the longitudinal direction with an electrode active material, the shape of protrusions and recesses is transferred to the uncoated part 2 and after drawing the uncoated part 2, the electrode foil 10 for a battery is pressed continuously in the longitudinal direction. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
