Does uneven coating thickness of lithium battery reduce coating speed ratio?

In the process of coating lithium battery, the uneven coating thickness will affect the performance of the battery, so try to keep the coating thickness uniform. The coating thickness is uneven, and one way to reduce the coating speed ratio is to reduce the moving speed of the coating head or increase the nozzle distance. Doing so can give the coating unit more time to distribute the adhesive on the electrode surface, thus reducing the unevenness.

Auxiliary tools such as compass on the electrode surface can also be used to help adjust the spraying position and speed to ensure the uniform and stable coating thickness.
