MSK-AFA-DS300-LD Vertical Double-Side Roll-to-Roll Coater for Battery Electrodes with Max 260mm Coating Width and Precise Blade Coating
The MSK-AFA-DS300-LD is engineered to meet the demands of producing double-sided electrode coatings for advanced battery technologies such as lithium-ion, graphene thin films, ceramic coatings, NiMH, and Ni-Zn batteries. Its vertical roll-to-roll design enables efficient processing of foam and mesh-type substrates, which are commonly used in battery electrode fabrication. The compact footprint of the system allows it to fit conveniently in laboratory environments where space is limited.
This coater employs a blade coating method that delivers high precision in coating thickness, with a typical tolerance of ±5 micrometers depending on the coating material properties. The maximum substrate width accommodated is 280 mm, with a maximum coating width of 260 mm to allow for edge clearance. The system includes an automatic alignment device to maintain coating accuracy within ±0.2 mm, ensuring uniform application across the substrate width.

Typical Applications
This coater is ideal for fabricating double-sided electrodes used in lithium-ion batteries, nickel-metal hydride (NiMH), nickel-zinc (Ni-Zn), graphene thin films, and ceramic coatings. It is particularly suited for coating foam and mesh substrates that require precise and uniform application of electrode materials.
Configuration & Operating Notes
Optional accessories include slurry pumps for continuous feeding of coating material to enable longer coating runs. Users should ensure compressed air supply within specified pressure range and install a two-stage pressure regulator if using gas cylinders to maintain safe operation. The system’s drying zone uses infrared heating with adjustable venting to optimize drying conditions for various coating materials.
