Poly(vinylidene Fluoride) as an Polymer Electrolyte in Lithium-IonBatteries

Poly(vinylidene fluoride) (PVDF) is increasingly recognized as a promising electrolyte material inlithium-ion batteries (LIBs) due to its excellent chemical stability, mechanical properties, andelectrochemical performance. This review explains PVDF’s role as an polymer electrolyte, focusingon its properties, performance, and recent advancements. PVDF’s high dielectric constant, thermalstability, and film-forming abilities make it suitable for gel polymer electrolytes (GPEs). However,their use is associated with challenges such as low ion conductivity. The presence of additives suchas plasticizers, lithium salts, and nanomaterials can improve its low ionic conductivity. Furthemore,innovations like functional modifications, nanocomposites, and electrospinning techniques aim toenhance its performance, boosting the safety, efficiency, and performance of LIBs
