Water-based adhesive for lithium-ion batteries LA 132/LA 133
--Suitable for the bonding of various lithium-ion battery positive and negative materials
Product Features:
Significantly reduce the DC internal resistance of the battery DCR.
Improve battery low-temperature high-current discharge performance.
Extend battery cycle life (including 0 cycle).
Resistant to electrolyte, small pole piece swelling.
Good stability, high-speed shear resistance, freeze-thaw resistance.
High-speed rolling without sticking to the roll, improving the processing performance.
Applications:
LA132/LA133 water-based adhesive is an aqueous dispersion of acrylonitrile multi-element copolymer, which has good thermal and electrochemical stability, and is suitable for bonding various lithium ion battery positive and negative materials.
The amount of LA binder in the negative electrode slurry is 2 to 5%, and the amount of LA binder in the positive electrode slurry is 1.5 to 4% (the amount of LA binder can be appropriately increased by lithium iron phosphate).

Water-based adhesive for lithium-ion batteries LA136D
--The upgraded product of LA132/LA133 series of water-based adhesives
Product Features:
Higher molecular weight, low swelling degree, stronger adhesion.
The amount of adhesive can be reduced by 40%.
The softness of the pole piece is improved, no need to add additives for softening.
Stronger electrolyte resistance and significantly improved battery performance.
Applications:
LA136D water-based adhesive is an aqueous solution of acrylic acid derivative multi-element copolymer with good thermal stability and electrochemical stability. It is suitable for bonding silicon carbon anode and high-end carbon anode materials.
Excellent electrolyte resistance, and the swelling degree is much lower than the traditional water-based negative electrode binder.
The amount of LA136D binder in the negative electrode slurry is 1.5%~2.5%, and the recommended amount is 0.5%CMC+1.5%LA136D.
