💡 Novelty & Significance:
The novelty is a fluorine-free, water-processable binder (polyacrylic acid/carboxymethyl cellulose crosslinked by citric acid) using combined hydrogen, covalent, and ionic bonding. It matches polyvinylidene fluoride performance, improves cycle stability, enables direct recycling without fluorinated residue, and cuts energy and emissions. This offers a scalable, sustainable route to circular lithium-ion battery manufacturing.
