Abstract
Disclosed herein relates to an electrode sheet drying device including a guide roller having a plurality of perforated holes formed on the outer circumferential surface, and the guide roller is configured to vacuum cling an electrode sheet to prevent an electrode sheet from being lifted from the guide roller during a drying process, thereby having an effect of mitigating the occurrence of creases in a non-coated part and preventing lifting of a current collector and the occurrence of cracks.
