CONDUCTIVE THIN FILM, PREPARATION METHOD FOR CONDUCTIVE THIN FILM, ELECTRIC CURRENT COLLECTION AND TRANSMISSION MATERIAL, AND ENERGY STORAGE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/041444
Kind Code:
A1
Abstract:
A conductive thin film, a preparation method for a conductive thin film, an electric current collection and transmission material, and an energy storage device, which relate to the technical field of conductive thin films. The conductive thin film comprises a thin film base material (10), a first metal plating (20), a second metal plating (30), a PI film (40), a PP film (50), a third metal plating (60) and a fourth metal plating (70), wherein the first metal plating is formed on one surface of the thin film base material by means of a vacuum coating apparatus; the second metal plating is formed on the first metal plating by means of a hydro-plating device; the PI film is laminated on an outer surface of the second metal plating by means of a coating lamination device in a single-sided manner; the PP film is laminated on the PI film by means of the coating lamination device; the third metal plating is formed on an outer surface of the PP film by means of a magnetron sputtering plating apparatus; and the fourth metal plating is formed on the third metal plating by means of the hydro-plating device. According to the conductive thin film, the limitations on the thickness of an outer-layer thin film base material are reduced, and the strength and compactness of a plating material are improved.
