BA-290S3
A Water-based Polyacrylate Binder for Effectively Suppressing Electrode Expansion and Efficiently Improving Cell Durability
Aiming to replace the traditional SBR+CMC binder system, this non-toxic polymer binder (Polyacrylate) for Li-ion Battery Anode features strong electrolyte resistance and high viscosity.
It is widely applied to various Silicon-based Anode.
- Excellent adhesive properties, can provide good adhesion between the electrode materials as well as between the electrode material and the electrode sheet substrate
- Excellent flexibility for negative electrodes is available when using binder of BA-290S3
- Excellent thermal stability ( 270 ℃ at least for Decomposition temperature)
- Excellent grinding stability, and is suitable for high-speed mechanical dispersion with powder
- Excellent freeze-thaw stability
- Excellent storage stability
- Excellent electrochemical stability between 0-5V
- Excellent dispersion to powder materials such as graphite. This generate an evenness and fineness to get a better performance for the electrodes.
- No thickening agent needed for slurry-processing; No organic defoamer needed to eliminate the bubles generated in the pulping process, a vacuum degass is working fine; Water is the only volatile matter during the coating and drying; No wasted water, no wasted gas, no industrial residue generated in the process, there is also no risk of firing, explorion and poisioning.
