High-speed Slot Die Coating Systerm

SS-SMARTECH High-speed Slot Die Coating System is a high precision pre-metered coating system, by evenly coating the prepared slurry on the substrate with high precision and then winding after dry treatment, to prepare for the later process. It solves the problems of poor accuracy, low efficiency, high energy consumption and coating liquid exposure to the environment of the traditional transfer coating, which is suitable for the cathode and anode coating of lithium-ion batteries, and can also be widely used in papermaking, optical film and other industries.

System workflow

Application scenarios

Slot Die Coating is the most widely used in the manufacture of lithium-ion batteries, where the fluid (slurry) is coated on a substrate such as copper foil/aluminum foil with uniform motion by squeezing through a special flow path.

It has the advantages of fast coating speed, high precision, uniform wet thickness, closed coating system to prevent the slurry from being polluted, high utilization rate of slurry, and stable slurry properties. And can be multi-layer coating at the same time, can be applied to a large range of different slurry viscosity and solid content.

Main Advantages
