MSK-AFA-HRP-150 is a benchtop roll-to-roll electrode coating system. Such a system features electrostatic dust remover for a particle-free coating environment. The calendar with pressure readings allows thin films to be densified right after the bake-out. The roll-to-roll fashion enables the continuous treatment process: substrate feeding, tape casting, bottom heated drying, roll pressing, reeling the processed films. It is ideal for coating applications such as lithium-ion battery electrode slurry, solid-state electrolyte film, and ceramic film research.
