Development of Membranes Based on Polyvinylidene Fluoride for Lithium Batteries
Two methods for producing lithium-conductive polymer films based on polyvinylidene fluoride (PVDF) were studied: saturating a dielectric PVDF film with a lithium-conductive solution and incorporating a lithium-conductive solution into a PVDF solution, followed by the fabrication of a lithium-conductive film. A comprehensive set of electrophysical studies on the properties of the proposed gel-polymer electrolyte across a wide temperature range (20–70 ℃) and frequency range (0.1 Hz–32 MHz) was conducted.
