Device for electrode plate testing

Abstract

This application provides a device for electrode plate testing that can effectively perform full-zone areal density testing on an electrode plate material. The device includes: a radiation mechanism, the radiation mechanism being configured to emit a ray to an electrode plate, where the ray is set along a width direction of the electrode plate to cover the electrode plate, and scan the electrode plate along a length direction of the electrode plate; and a probe mechanism, the probe mechanism and the radiation mechanism being disposed opposite on two sides of the electrode plate, where the probe mechanism is configured to monitor a signal transmitted through the electrode plate, and the signal is used to test areal density of a material applied on a surface of the electrode plate.
