Electrode Sheet Drying Device Capable Of Preventing Thermal Wrinkles In Uncoated Portion

Abstract: The present invention relates to an electrode sheet drying device capable of preventing thermal wrinkles in an uncoated portion. The electrode sheet drying device is a device for drying an electrode sheet comprising: a pair of coated portions formed by coating one surface of a metal foil with an electrode active material; and an uncoated portion located between the pair of coated portions and not coated with an electrode active material. The present invention relates to an electrode sheet drying device comprising: a chamber which has a rectangular structure and in which the electrode sheet is dried; a heating means disposed at the upper side of the chamber to adjust the temperature in the chamber to a temperature for drying the electrode sheet; and at least one guide roll for guiding movement of the electrode sheet in the chamber and maintaining tension of the electrode sheet, wherein a portion of the electrode sheet moves while being spaced a predetermined distance apart from the guide roll.
