Secondary battery electrode, and method for producing same
摘要
說明書
However, in the method of producing an electrode for a secondary battery according to an exemplary embodiment of the present invention, since the method is based on a slicing-adhesion process of an active material bulk, the method is fundamentally free from problems arising from a process of coating a slurry on a thin conductive substrate as in the conventional process, for example, problems that a conductive substrate wobbles by dry air volume adjustment, a thickness variation between an edge portion and a central portion depending on drying conditions occurs when drying after coating under high loading conditions, and thus, an electrode material in the edge portion is desorbed in a subsequent rolling process, by applying a process of adhesion after slicing instead of a coating process.
In addition, in the production process of the active material bulk, uniform dispersion and mixing are possible by kneading with a relatively small amount of a solvent, a dilution process for lowering a viscosity for coating is unnecessary, efforts to secure long-term phase stability of the slurry by viscosity adjustment are unnecessary, and the process may be simplified.
In addition, in the method of producing an electrode for a secondary battery according to an exemplary embodiment of the present invention, since a large amount of active material films are produced based on a bulk, an electrode having extremely uniform quality may be mass-produced by a simple process of slicing-adhesion, and an electrode having extremely uniform quality may be mass-produced.
