Equipment functions and parameters
Introduction to Equipment Functions and Principles
This equipment is used for precision coating of cathode and anode electrode of lithium-ion batteries. It mainly consists of unwinding part, machine head part, oven part, traction part, winding part, and electric control part; Evenly coat the stirred slurry onto the substrate, ensuring that the size, weight, etc. are within the process range. After drying treatment, roll it up and prepare for the subsequent process.
