Zusammenfassung: | A method of preparing an electrode for a secondary battery according to one embodiment of the present invention comprises: a step for injecting, into a single coating device, a first slurry prepared by dissolving a first active material in a first solvent and a second slurry prepared by dissolving a second active material in a second solvent; and a step for applying the first slurry and the second slurry on a current collector through the single coating device, wherein the first solvent and the second solvent have different physical properties from each other, and a layered structure of a first layer including the first slurry and a second layer including the second slurry is formed on the current collector.
Un procédé de préparation d'une électrode pour une batterie secondaire selon un mode de réalisation de la présente invention comprend : une étape d'injection, dans un seul dispositif de revêtement, d'une première bouillie préparée par dissolution d'un premier matériau actif dans un premier solvant et d'une seconde bouillie préparée par dissolution d'un second matériau actif dans un second solvant ; et une étape d'application de la première bouillie et de la seconde bouillie sur un collecteur de courant à travers le dispositif de revêtement unique, le premier solvant et le second solvant ayant des propriétés physiques différentes l'un de l'autre, et une structure stratifiée d'une première couche comprenant la première bouillie et une seconde couche comprenant la seconde bouillie est formée sur le collecteur de courant.
