Automatic Roll To Roll Electrode Coating Machine For Li-ion Cell Manufacturing

Introduction:

LITH-AFA-MC400 is a versatile roll to roll coating system which can adapt various coating heads such as reverse comma blade, Doctor Blade, Slot Die and Micro Gravure and Tape Casting. A 4.5 meters long, three zone convection drying oven with independent temperature programming is implemented for efficient slurry curing. This is the most complete and universal pilot coating system that provides a broad adaptability to various coating slurries and film substrates (Cu, Al, PET, PP, PE).

• Doctor Blade: Cost effective solution for 8~200 micron thick coatings (Continuous mode only)
• Reverse Comma Blade (Transfer Coating): Cost effective solution for 30~200 micron thick coatings (Both continuous & intermittence mode)
• Tape Cast Coating: Ideal for performing thicker coating up to 1000 microns with high viscosity slurry
• Micro-Gravure: Perfectly suitable for precise thin coatings from 1~3 microns （dry film thickness）
• Slot Die: Suitable for precision coatings as thin as 1 micron while providing a wide coverage for thicker coatings upto 200 microns

Coating Heads Reverse Comma Blade Doctor Blade Tape Casting Slot Die Micro-Gravure	Doctor Blade Coating	Continuous coating mode only Coating thickness range: 10~200um  ( dried film ) Typical slurry viscosity range: 500~10000 mPa.s Precision: ±5μm (gap adjustment solution 1um); Edge to center thickness tolerance +/-8um MSK-155 auto-slurry feeder with 2 liters tank is available at extra cost, please click underline to view details.
	Reverse Comma Blade (Transfer Coating)	Two available coating modes (continuous and intermittent) selectable on the control panel. Coating thickness range: 30~200um  ( dried film ) Typical slurry viscosity range: 500~10000 mPa.s Precision: ±3μm; Edge to center thickness tolerance +/-5um MSK-155 auto-slurry feeder with 2 liters tank is available at extra cost, please click underline to view details.
	Cast Coating	Tape casting technique is ideal for handling thicker slurry 5000~20000 mPa.s and thus thicker film coating is achievable (up to 1000um) Continuous coating mode only Precision: ±5μm (gap adjustment solution 1um); Edge to center thickness tolerance +/-8um   MSK-156 slurry feeding screw pump with 4 liters tank is included, please click underline to view details
	Slot Die coating	The slot die is perfect for uniform film coating of 1 micron and up to 200-micron thickness. By changing the shim size with various patterns, you would be able to produce continuous, intermittent, or even grid coatings that match the shim patterns. Please refer to the pictures in below for more details:                           Slurry feeding screw pump with 4 liters tank is included, please click underline to view details Minimum thickness & precision: 1 µm ( dried film ), ±1%   Typical slurry viscosity range: 200~10000 mPa.s Attention: The final coating thickness is dependent on a wide range of parameters such as slurry viscosity, solid particle size, solid content, shim thickness, foil rolling speed and slurry feeding rate. Therefore, we are not able to guarantee that 1-micron level film is achievable for all kinds of slurries. For further discussion, please let us know your slurry specs and coating thickness requirement.
