Product Detail

Battery Separator Coating Machine


SPECIFICATIONS


Functions and principles

This battery separator coating machine is used for precision coating of lithium-ion battery separators. It mainly consists of an unwinding part, a machine head part, an oven part, a traction and winding part and an electronic control part. Apply the stirred slurry evenly on the substrate to ensure that the size and weight are within the process range. After drying, it is rolled up to make preliminary preparations for the subsequent processes.
