[0002] Lithium battery coating is a critical manufacturing process that involves uniformly coating a suspension containing positive and negative electrode active materials onto a metal foil, typically copper or aluminum foil, and then drying it to form a film. Lithium battery coating involves using coating equipment to apply a polymer paste, molten polymer, or polymer solution onto copper or aluminum foil to create a composite film.

[0003] Coating machines, especially lithium battery coating machines, are important equipment in the battery manufacturing industry. They are mainly used to evenly coat electrode slurry on the surface of metal foil such as copper foil or aluminum foil, and then make positive and negative electrode sheets through subsequent processing. The coating die, also known as the scraping die, is the core component of the coating machine. It can evenly cover the viscous coating or ink on the surface of the substrate to form a smooth coating layer. Depending on the coating method, coating dies can be divided into many types, such as extrusion coating dies, roller coating dies, spray coating dies, etc. These different types of coating dies are suitable for different coating and printing processes.
