Poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP)-based Gel Polymer Electrolyte (GPE) plasticized with a LiPF6-carbonate liquid electrolyte represents one of the most mechanically robust and electrochemically stable gel systems for advanced lithium-ion batteries
The main features of the LiPF6/PVDF-HFP-Based gel polymer electrolyte are: (1) Dual-Phase Morphology: The semi-crystalline structure features crystalline PVDF blocks providing structural integrity and mechanical strength, while amorphous HFP domains swell extensively with liquid carbonate electrolytes, trapping them within a three-dimensional polymer network. (2) High Ionic Conductivity: Swelling with 1.0 M LiPF6 liquid electrolyte yields high room-temperature ionic conductivity (>10^{-3} S/cm comparable to liquid electrolytes while eliminating free-flowing liquid leakage risks. (3) Interfacial Compatibility: Exhibits excellent wettability and stable solid electrolyte interphase (SEI) formation when paired with both high-voltage cathodes and graphite or silicon-carbon anodes.
