說明書
An adhesive layer may be formed on each of one surface of the current collector, one surface of the active material film, or one surface of the current collector, and one surface of the active material film. The adhesive layer may be formed by applying an adhesive on at least one of the surface of the current collector and the surface of the active material film, when the adhesive is a fluidized bed. Application of the adhesive may be performed by any application method which is commonly used in the application in a liquid phase or dispersed phase, and for example, may be performed, as an example, by one or more application methods selected from the group comprising dip coating, spin coating, casting, bar-coating, gravure-coating, blade coating, and roll-coating, spray, screen printing, inkjet printing, electrostatic hydraulic printing, micro contact printing, imprinting, gravure printing, offset-reverse offset printing, and the like, and coating may be performed in the form of surface coating, line coating, dot coating, and the like, but is not limited thereto. When the adhesive is in the form of an independent film, the adhesive film may be adhered to at least one of the surface of the current collector and the surface of the active material film. Here, the application amount of the adhesive may be in the level of 0.1 to 1 mg/Cm2, but is not limited thereto.
