Electrode plate testing method and apparatus

Abstract

This application provides an electrode plate testing method and apparatus, so as to effectively detect the surface density of an electrode plate material in its entirety. The method includes: acquiring a signal transmitted by an electrode plate under irradiation by a ray, where the ray is arranged in a width direction of the electrode plate and covers the electrode plate, and scans the electrode plate along a length direction of the electrode plate; and detecting a surface density of a material applied on a surface of the electrode plate based on the signal transmitted by the electrode plate.
