Separator film manufacturers employ a gravure process where the doctor blade is crucial for achieving a uniform ceramic coating thickness on a base film, optimizing separator film performance. This process is also used in anode and cathode manufacturing to apply electrode slurry to materials such as copper and aluminum.

Specialty coatings, applied with tools like slot die, doctor blade, and anilox roller during lithium-ion battery production, are crucial for optimizing energy storage capabilities and discharge efficiency by ensuring a consistent and uniform thickness of the anode and cathode materials’ electrode coating.
