A reaction vessel in the form of a box is sized to closely contain electrode elements or core cell elements of a lithium-based or sodium-based battery or capacitor for contacting of the electrode material, placed in the reaction vessel, with a flowing gaseous stream of an inert carrier gas and vapor of an organic solvent of water for removing residual water from the porous electrode material elements which are to be infiltrated with a non-aqueous electrolyte solution. Complementary equipment is provided for delivering the gaseous stream to the reaction vessel with predetermined portions of carrier gas and organic vapor at a predetermined temperature, pressure, and flow rate.

An electrode-slurry-drying device according to one or more embodiments of the present disclosure includes a nozzle configured to spray gas to dry an electrode slurry comprising a solvent applied on a substrate; and a nozzle plate at an outlet of the nozzle, and defining perforations for discharging the gas toward the substrate, wherein a number of the perforations is determined based on an amount of undried solvent on the substrate.

A nozzle member and a drying device for manufacturing a secondary battery. The nozzle member can uniformly dry even in regions where the width of the electrode plate changes by utilizing a number of nozzle parts having the same shape, and a drying device including the same. The nozzle member includes a number of nozzle parts spaced apart from each other, and each of the nozzle parts includes a frame; an inlet part connected to the frame and into which the dry material is configured to flow; a discharge part in contact with the frame and configured to discharge the dry material; and a flow part between the inlet part and the discharge part. The frame includes an insertion part, the inlet part is fixed to the frame, and the discharge part is movable.
