  • Publication number: 20240079550
    Abstract: Provided is a flexible air supply damper system for preventing an overdrying-caused defect of a secondary battery electrode plate, the flexible air supply damper system including: a fluid supply unit supplying a fluid; a heating unit heating the fluid supplied through the fluid supply unit; a drying unit drying the electrode plate while receiving the fluid heated through the heating unit; a damper unit splitting the fluid passing through the heating unit to control an amount of the fluid to be introduced into the drying unit; and a discharge unit through which the fluid used in the drying unit and the fluid split out of the damper unit are discharged. By controlling the amount of the fluid to be introduced into the drying unit, the electrode plate is prevented from being overdried.
