Description

technical field [0001] The invention relates to the technical field of lithium battery processing, in particular to coating equipment for lithium battery processing. Background technique [0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive and negative electrode materials and uses non-aqueous electrolyte solution. In the production process of lithium battery, the coating of pole piece affects the capacity, consistency and safety of lithium battery. It is of great significance. Pole piece coating generally refers to a process in which a uniformly stirred slurry is evenly coated on a foil substrate, and the organic solvent in the slurry is dried. Some existing lithium batteries During the working process of the coating equipment for processing, the surface of the foil substrate to be coated cannot be cleaned. The impurities on the surface of the foil substrate will cause quality defects in the coating, reduce the quality of the pro...

[0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the positive and negative electrode materials and uses a non-aqueous electrolyte solution. During the production process of lithium batteries, the coating of pole pieces has a great impact on the capacity, consistency and safety of lithium batteries. It is of great significance. Electrode coating generally refers to a process of uniformly coating the evenly stirred slurry on the foil substrate and drying the organic solvent in the slurry. Some existing lithium batteries During the working process of coating equipment for processing, the surface of the foil substrate to be coated cannot be cleaned. Impurities on the surface of the foil substrate will cause quality defects in the coating, reduce product quality, and it is inconvenient to adjust the thickness of the coating , In addition, during the long-term storage of the slurry, the slurry will precipitate, resulting in uneven density of the slurry and changes in the flow characteristics of the slurry, which in turn will affect the coating of the pole piece
