Q: Can it perform intermittent coating?
A: Yes. The slot die coating method, when combined with the appropriate coating valve and die gasket, can achieve intermittent coating, strip coating, and grip coating in addition to continuous coating.
Q: What materials can be coated?
A: The machine handles both cathode materials (LCO, LFP, LMO, NMC) and anode materials (Graphite, LTO) with either NMP (oily) or DI-water (water-based) solvents.
Q: What is the maximum coating speed?
A: The mechanical speed is up to 15 m/min, while the coating speed is ≥1 m/min (depending on slurry properties).
Q: What is the coating width range?
A: The coating width is ≤320 mm for both cathode and anode electrodes.
Q: How is the coating thickness controlled?
A: For comma bar coating, a precision adjustment mechanism with micrometer is used. For slot die coating, the metering pump feeding amount is adjusted based on coating speed. The system also reserves a test communication interface for thickness/surface density monitoring.
Q: What is the drying system like?
A: The machine features a 2-meter hot air circulation oven with electric heating. Temperature can reach up to 150°C with ±5°C uniformity within the oven. The oven is constructed with stainless steel inner tank (SUS304) and housing (SUS201).
