In the production process of lithium batteries, slurry coating is a crucial process. Its main purpose is to uniformly coat the slurry with good stability, viscosity, and fluidity onto the positive and negative current collectors, which is of great significance for the capacity, consistency, and safety of lithium batteries. However, according to incomplete statistics, the proportion of battery failures caused by the electrode coating process among all lithium battery failures due to various reasons reaches 10% - 15%.
