PREPARATION METHOD OF ELECTRODE, ELECTRODE FORMED THEREFROM, AND ELECTROCHEMICAL DEVICE HAVING THE SAME

摘要

The present invention relates to a manufacturing method of an electrode, an electrode formed thereby, and an electrochemical device including the same. The manufacturing method of an electrode of the present invention comprises (S1) a step of manufacturing first slurry by dispersing first electrode active material particles in a first binder solution obtained by dissolving a first binder in a solvent; (S2) a step of manufacturing second slurry by dispersing second electrode active material particles different from the first electrode active material particles in a second binder solution obtained by dissolving a second binder in a solvent; (S3) a step of successively coating the manufactured first and second slurry on at least one side of a current collector in a layer form or (S3) a step of independently coating the manufactured first and second slurry on at least one side of the current collector in separated sections; and (S4) a step of removing the solvent from the product of (S3). According to the manufacturing method of the present invention, active materials with mutually different components are able to be selected and coated, and an electrode in which active materials supplementary or synergic in the performance despite the mutually immiscible property are efficiently applicable to the current collector is able to be manufactured.
