A method for at least partially drying a substrate. The method includes: (a) directing a supply air flow onto the substrate with a direction component in either the transport direction, or the opposite direction and (b) directing an exhaust air flow away from the substrate. The method is reproducible and effective and achieves an improved result with respect to the homogeneity and speed of drying because the exhaust air flow is split into a plurality of sub-flows by supplying each of the sub-flows to an individual intake channel, and because, in the event of a supply air flow in the transport direction of movement of the substrate, the supply air flow is arranged spatially upstream of the exhaust air flow and, in the event of a supply air flow in the opposite direction, the supply air flow is arranged spatially downstream of the exhaust air flow.

Provided is an electrode drying apparatus including a moisture supply unit capable of setting the internal temperature of a drying oven to a reference value, which is a level at which the drying of an electrode to be dried is stabilized, before an electrode drying process using hot air is started, thereby preventing the electrode from being fractured by over-drying at the early stage of drying the electrode in the drying oven, and an electrode drying method using the same.
