Lithium polyacrylate (PAALi) is a water-soluble binder, and it contributes to increasing the adhesion effect between the fibers. Polyacrylates were applied as binder for the electrode of a particulate mixture of silicon, graphite, and Ketjen black for lithium-ion batteries. The poly(alkali acrylate) binder remarkably improved the electrochemical lithiation and delithiation performance of the silicon-graphite electrode compared to that of conventional binders. The polyacrylate coating on Si and graphite particles suppressed the electrode deterioration. When the electrode was prepared with 30 wt% poly(sodium acrylate) binder, the higher specifi c capacity and initial efficiency were obtained with much improved cycleability.

Product Advantages:
1. With excellent bonding property, it can provide good adhesion between electrode materials and electrode sheet substrate.
2. Commercialized mass production of products with stable quality.
3. Good electrochemical stability, high polymer strength, can adapt to the negative volume expansion of silicon, excellent cycling performance, applied to silicon anode electrode research.
4. It is convenient to carry out research on pouch cell and coin cell.
5. Lithium PAA, PH~8, does not affect the first efficiency of the material.
Method of use:
1. Adjust the amount of water according to the actual process and control the final slurry viscosity.
2. When the dispersion reaches the required fineness, filter, remove the bubble and discharge the material.
