(1) Mixing of raw materials
Positive electrode: Place a proportion of polyvinylidene fluoride (PVDF) and nitromethylpyrrolidone (NMP) in the stirring
Mix in the mixer and adjust the mixer speed; Then add the positive electrode active substance and carbon black, vacuum and adjust
Adjust the speed of the mixer.
Negative electrode: Mix the latex and water in proportion in the mixer, and adjust the mixer speed to; then
Add CMS, vacuum, and adjust the mixer speed.
(2) Coating
Place the aluminum strip (negative electrode is copper strip) flat and straight on the coating machine, ensuring that the aluminum strip is not skewed or wrinkled
Smooth belt running, no material leakage, and no slipping. Apply the prepared slurry evenly on the machine and set the corresponding parameters,
This includes the positive electrode slurry speed, negative electrode slurry speed, oven temperature, and coating width. During the transportation process, it is necessary to
Observe whether the slurry is straight, without inclination, or misalignment, and whether the slurry thickness applied to the aluminum strip (copper strip) is uniform
Consistent.
(3) Vacuum drying
Place the coated positive and negative electrodes in a vacuum oven for drying, with a vacuum degree of -0.09MPa.
(4) Cut large pieces
Cut the coated positive electrode into large pieces of a certain length (depending on the specific battery design), using a cutting machine
The walking speed is 55mm/min, and the incision is required to be free of burrs.
