PAA {Poly(acrylic acid)} is one of the most promising and high-performing advanced binders, particularly vital for use in next-generation Silicon (Si) anodes. It is a water-soluble polymer, allowing for an environmentally friendly and cost-effective aqueous electrode processing. It has abundant -COOH groups form powerful hydrogen bonds with the hydroxyl groups (Si-OH) naturally present on the surface of silicon and graphite particles. This strong chemical interaction provides significantly higher adhesion strength than the weak van der Waals forces of traditional binders like PVDF.
