Lithium Polyacrylate (LiPAA) Battery Binder
Package Size: 2.5 kg / pack
Lithium Polyacrylate (PAALi) is an advanced aqueous binder highly optimized for silicon (Si) anodes in lithium-ion batteries. Characterized by abundant carboxyl groups, PAALi readily forms strong hydrogen bonds with the surface functional groups of Si materials.
This interaction promotes the formation of a highly stable solid electrolyte interphase (SEI) film, ensuring superior cycling stability. By creating a dense and uniform film within the electrode, PAALi maximizes electrical contact between the active materials and the current collector.
Key Advantages
Optimized for Si-Anodes: The high concentration of carboxyl groups significantly improves the cycling performance of silicon anodes through robust hydrogen bonding and stable SEI layer formation.
Enhanced Battery Metrics: Effectively increases overall anode capacity, minimizes internal impedance, and improves long-term cycle coulombic efficiency.
Superior Electrical Contact: Forms a dense matrix in the electrode sheet, significantly increasing the continuous electrical contact between the active substance and the current collector.
