Abstract

The present application provides a coating die and an electrode plate coating device, where the coating die is provided with an inlet, a first distribution cavity, a plurality of distribution channels, and a plurality of coating outlets. The plurality of coating outlets are spaced apart along a first direction. Each distribution channel is provided with an inlet port and an outlet port at two respective ends thereof. The inlet port is in communication with the inlet, each outlet port is oriented toward a corresponding coating outlet, and cross-sectional areas of the inlet ports of all of the plurality of distribution channels are equal. Since the cross-sectional areas of all the inlet ports of the distribution channels are equal and the outlet port of each distribution channel corresponds to a respective coating outlet, the slurry can be evenly distributed and guided to the plurality of coating outlets under the action of the distribution channels, reducing the problem of uneven slurry amounts obtained by the coating outlets during free flow, which facilitates improving the consistency of discharge from the plurality of coating outlets and enhances the uniformity of slurry coating in the coating process.
