The coating process is divided into three sections, one is the slurry system, the other is the coating system, and the third is the polar dried system. The triple -in -one requires each system to maintain stability to ensure the consistency of the pole. This article will affect the consistency of lithium battery performance from the perspective of coating. The slurry system is transferred to the slurry tank after the mixing is completed, and the diaphragm pump is transferred to the transition cylinder, and the s
