PVDF-HFP {Poly(vinylidene fluoride-co-hexafluoropropylene) is a copolymer of Poly(vinylidene fluoride) (PVDF) and Hexafluoropropylene (HFP). The copolymer structure is designed to mitigate the high crystallinity of pure PVDF while maintaining its highly desirable electrochemical properties. The strong electron-withdrawing C-F groups increase the material's dielectric constant, which enhances the dissociation of the lithium salt (LiTFSI, LiPF6, etc.), generating more mobile Li+ carriers. It exhibits a wide stability window, often reaching 4.7 V to 4.9 V vs. Li/Li+ (and higher with certain fillers), making it compatible with high-voltage cathodes like NMC.
