Lithium Polyacrylate (PAALi)

Lithium polyacrylate (PAALi) is a water-soluble binder. It can significantly enhance the electrochemical performance of battery cathodes and anodes, because it is an ion-conducting polymer that contains excess Li⁺ ions, which it can donate to make up the Li loss. PAALi is mostly used in lithium-sulfur batteries and silicon-based lithium batteries. Alfa Chemistry offers high-quality PAALi. Please contact us for pricing and more information on this product.

Properties

PAALi possesses several advantageous properties that make it suitable for use as a binder in battery applications:

Adhesion. PAALi has excellent bonding properties and can provide good adhesion between electrode materials and between electrode materials and electrode substrates.
Polysulfide adsorption. PAALi binder can effectively adsorb polysulfides, which is crucial to improve the performance of lithium-sulfur batteries. The adsorption of polysulfides can enhance the battery's cycling performance and rate performance.
Electronic and Li⁺ conductivity. PAALi binder has good electronic and Li⁺ conductivity, which helps to improve the energy conversion efficiency and battery life of lithium-sulfur batteries.

Chemical stability. PAALi is able to remain stable in a given electrode/electrolyte system, resist electrolyte corrosion, and does not undergo redox reactions within the operating voltage.
Flexibility. PAALi has excellent flexibility and can adapt to volume changes during battery operation.
Cost-effectiveness. Compared with traditional polyvinylidene fluoride (PVDF) binder, PAALi binder is inexpensive to make, which suggests that it has great development prospects in lithium-sulfur batteries.

Application Note

Adjust the consistency of slurry by adding water to avoid the edge folding phenomenon of slurry.
When the dispersion reaches the required fineness, filter, remove the bubble and discharge the material.
