DRYING DEVICE AND DRYING METHOD FOR ELECTRODE SHEET

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-adsorb 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.
