How to judge whether the quality of lithium battery coating?

　　1) How to judge the quality of the coating quality?

　　The surface of the polar sheet is flat, smooth, uniform, good adhesion, dry, dry, non -removal, no material, lack of materials, no accumulation of dust, granules, no scratches, no bubbles, as good pieces, with defects, there are defects, there are defects It is a bad film.

　　2) What factors are related to the uneven membrane density and how to adjust it?

　　Unexplained: The slurry is uneven, the local solid liquid is larger than the large membrane, and the liquid is smaller than that the membrane density is smaller, and the stirring is strengthened.

　　Undeverance of verticals: uneven knife seams, crooked knife or coating roller, scraper have been deformed, and should be adjusted or replaced.

　　The horizontal uniformity is uneven: the speed of the coating roller or the back roller fluctuates, and it should be maintained.

　　3) Where to determine whether the alarm has been dry and temperature is too high?

　　No sticky roller, no curls, the temperature of the sticky roller is too low, and the temperature is too high.

　　How to judge the quality of the coating

　　4) How to judge the bonding performance of the polar sheet?

　　I do n’t have to drop it, tear it with a tape, and see how much the residue is. The positive pole is greater than 1/3 and the negative pole is greater than 1/2. It can be considered that the adhesion is good.

　　5) How to deal with the correct hand when you can't pass the particles? Use a semi -ruler to plug it. If a lot of particles should stop

　　6) Is the relationship between the quality of the sword and the quality of the coating pole?

　　Ensure that the membrane density is uniform and consistent (interspersed the effect of membrane density on battery performance, the performance of the capacity)
