Electrode slurry coating process selection

Generally, the coating method needs to be considered from the following aspects, including: the number of layers coating, the thickness of the wet coating, the rheological properties of the coating liquid, the required coating accuracy, the coating substrate, the speed of coating, etc.

How to choose the coating method suitable for the electrode slurry? In addition to the above factors, it is necessary to combine the specific conditions and characteristics of the electrode coating. Lithium-ion battery electrode coating features are:

1 double-sided single layer coating;

2 slurry wet coating is thick (100 ~ 300μm);

3 slurry is a non-Newtonian high viscosity fluid;

4 electrode coating accuracy requirements are high, and film coating accuracy is similar;

5 coated support is aluminum foil and copper foil with a thickness of 10 ~ 20μm;

6 The electrode coating speed is not high compared to the film coating speed.

Considering the special requirements of the application of the electrode slurry, extrusion coating or roller coating is available.
