Secondary batteries based on ion conduction are among the most promising technology for next generation mobile and stationary storage system due to their unmatched volumetric energy density. However the multiple emerging challenges which include electrochemical stability, transport efficiency and safety issues of these secondary batteries have attracted worldwide attention. The perspective of this review is that rational design of polymeric separator which is an essential component in rechargeable batteries separating anode and cathode, and controlling number of mobile ions is crucial to overall battery performance, including lifetime, safety as well as energy and power density of battery. There is impressive progress in the exploration of separator materials. Among them, poly(vinylidene fluoride-co-hexafluoropropylene) P(VdF-co-HFP) have received great attention as polymer host due to some its splendid collective property such as its amorphous nature, high room temperature ionic conductivity, high dielectric constant and the possibility of controlling the porosity of the materials through binary and ternary polymer/solvent systems. This review focuses specifically on recent advances in P(VdF-co-HFP) based separator cum gel polymer electrolyte with detailed analysis of several embedded functional agent that are incorporated to improve ionic conductivity, mechanical robustness and thermal stability of rechargeable batteries.

AbstractThe ionic conductivity of ammonium-based solid polymer films of poly(vinylidene fluoride) (PVDF) blended with MG49, a graft of natural rubber and poly(methyl methacrylate), with various compositions of ammonium triflate NH4CF3SO3, was investigated. As a result, 30 wt.% of NH4CF3SO3-doped polymer electrolyte exhibits the highest ionic conductivity at 6.32×10-4 S/cm at room temperature. The conductivity enhancement can be attributed to the increase in the number of NH4+ as charge carriers. The significance of the blend is the increase of one order in ionic conductivity as compared with pure PVDF electrolyte. The temperature dependence of conductivity of the electrolyte does not obey the Arrhenius law. However, the conductivity increases with temperature and it reached 1.56×10-3 S/cm at 363 K. X-ray diffraction reveals a decrease in crystallinity of the electrolyte upon the addition of NH4CF3SO3 salt. This result is supported by scanning electron microscopy. Linear sweep voltammetry demonstrates that the anodic stability of the electrolyte is up to 4 V. Therefore, the electrolyte shows good compatibility with high-voltage electrode. Hence, this electrolyte system can be a prospective candidate as lithium-ion conducting electrolyte for lithium batteries.
