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 binding silicon carbon anode materials.
It has 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.
Notice:
LA136D needs to be diluted slowly with DI water before use.
Adding PC or EC to the anode electrode slurry prepared by LA136D binder can increase the flexibility of the electrode and avoid delamination and cracking of the edge of the electrode. The amount is about 5% of the total solvent.
The maximum single-sided coating temperature of LA136D adhesive slurry is recommended to be controlled below 80℃. When the oven temperature is too high, electrode delamination and cracking may occur.
During the shelf life, the viscosity of LA136D adhesive increases with the increase of storage time, which is a normal phenomenon.
