Know the processing process of lithium battery ingredients in one article

C) After preparing the solution, check the solution: viscosity (check)\dissolution (visual inspection) and solidification time; D) negative electrode: SBR+CMC solution, mixing time and frequency. 2 Active material A) When weighing and mixing, monitor whether the number and quantity of mixing are correct; B) Grinding ball: grinding time with positive and negative electrodes; the share of agate beads and mixture in the ball mill barrel; a large ball And an example of a small ball in agate ball; C) Baking: set the baking temperature and time; check the temperature after cooling after baking. D) Mixing of active substance and solution: mixing method, mixing time and frequency. E) Sieve: 100 mesh (or 150 mesh) molecular sieve. F) Inspection and inspection: The following inspections were carried out on the slurry and mixture: solid content, viscosity, mixture fineness, vibration density, slurry density. Coating 1 first check the collection fluid A) the input of the collection fluid specifications (length, width and thickness); B) the approval of the assembly fluid specification (conventional) parts; C) the hydrophilic (hydrophobic) characteristics and appearance of the collection fluid (Whether there are abrasions, scratches, or damage). 2 Calculation of the amount of trimming (standard value, upper and lower limits) A) Single-sided trimming (the thickness of one side is subject to the extreme thickness of this specification); B) The amount of double-sided trimming (the thickness of the double-sided trimming is closest to this Confirm the thickness of the rod of the specification). 3. Whether the confession of the pulp is too thick (thin)\good fluidity, whether there are particles, too much foam, whether it is dry. The purpose of the 4 pole piece A) Self-whitening specific gravity (slice thickness); B) Appearance: whether there is a wire, broken strip, agglomerated material (poor roller rod), whether the material is excessively accumulated, whether it is dry or burnt, whether there is Bare copper or foreign particles; 5 pieces of burr and visual inspection standard permission.
