<P>PROBLEM TO BE SOLVED: To provide an electrode plate for a nonaqueous secondary battery having a stable film thickness in an electrode mixture paint and being equal in weight between a start end part and a final end part even just after starting of painting, wherein crack at a start end part of an electrode plate due to insufficient flexibility at pressing and breakage in winding a sheet-like electrode plate are suppressed, biting due to an electrode plate group using those electrode plates in housing a battery case and damage to the electrode plate group due to an increase in inserting pressure are suppressed, and failure such as capacity loss due to imbalance in weight between a positive electrode plate and a negative electrode plate is suppressed. <P>SOLUTION: A collector 1 is transported at a predetermined speed so that a circulated electrode mixture paint 2 is applied with a predetermined back pressure which is adjusted by a back pressure adjusting means for painting pressure. After the electrode mixture paint 2 is applied, the painting of the electrode mixture paint 2 is suspended for a while with a predetermined pressure maintained for molding a non-paint part 3. Thus, an electrode plate 4 for a nonaqueous secondary battery is provided in which weights at the start end part and the final end part are equivalent even just after starting of painting, and the collector 1 is applied with the electrode mixture paint 2 intermittently. <P>COPYRIGHT: (C)2010,JPO&INPIT |
