Coating Machine - Process flow

 

Fourth, the process requirements: positive and negative electrode coating:

Double-sided total dressing density:
1. The first coating length deviation is ≤ 2 mm, and the coating gap deviation is ≤ 1 mm. 2. The maximum misalignment between the second side and the first side is ≤ 1 mm.
3. The maximum deviation of the thickness of the coated single film is ≤3um, and the maximum deviation of the thickness of the double film is ≤6um. 4. The maximum deviation of the density of the coated single film is ≤ 4%, and the maximum deviation of the density of the double film is ≤ 8%. 5. The maximum error of coating tailing is ≤1mm.
6, the film surface should be flat, can not appear dry cracks, wrinkles, particles, streaks. 7. Coating width = single strip width multiplied by the maximum number of coatable sheets + 5 ~ 10mm.

Coating Machine - matters needing attention

 

1. The maximum temperature of the positive electrode coating should not exceed 125 oC on one side. The single surface is not easy to dry. The non-stick roller is the standard. The reverse speed is slow and thoroughly dried.
2. The temperature of the single side of the negative electrode should not exceed 105 oC, and the temperature of double coating should not exceed 110oC.
3. The coated pole piece must be completely baked. If it does not dry or has the phenomenon of stripping, the temperature of the temperature zone can be properly adjusted, the temperature can be lowered, the pole piece can be stripped, the temperature can be lowered, and the temperature can be raised.
4. The density is adjusted by adjusting the screw.
5, the thickness is adjusted by adjusting the screw, so that the two sides reach a consistent speech.
6. Adjust the speed and temperature to achieve the best coating.
