WIPO Patent Application WO/2023/134484
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application is a coating apparatus, which can form a high-precision pattern coating on a base film, thereby improving the performance of an assembly (such as a current collector) comprising the base film. The coating apparatus comprises: a resistance plating pattern unit (210), used for forming, on a partial region of a surface of the base film (230), a pattern composed of a resistance plating substance, wherein the resistance plating substance is used for limiting metal steam to form a coating; and a coating unit (220), used for applying the metal steam to the base film (230) having the pattern, so as to form a metal coating on the region where the resistance plating substance is not provided on the surface of the base film (230).
