The water-based adhesive LA132/LA133 is a aqueous dispersion of acrylonitrile polycopolymer, which has good thermal stability and electrochemical stability.
Precautions:
1. Adjust the consistency of slurry by adding water to avoid the edge folding phenomenonof slurry.
2. The small bubbles formed during the process of stirring can be eliminated by vacuumdefoaming oradding a small amount of alcohol or n-butyl alcohol.
3. The content of binder in the negative electrode is suggested 2～5%,positive is 1.5～4%(lithium ironphosphate can appropriately increase the amount of binder).
4. After drying the electrode, cool it in the air before rolling, cutting and winding.
5. Fully dry to eliminate the absorbed water before injecting liquid to the battery.
6. In shelf life, it is normal that the viscosity of product increases as time goes by.
