Highly porous lithium-ion conducting solvent-free poly(vinylidene fluoride-co-hexafluoropropylene)/poly(ethyl methacrylate) based polymer blend electrolytes for Li battery applications

Effective influences of 1-ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl) imide (EMIMTFSI) ionic liquid on the ion transport properties of micro-porous zinc-ion conducting poly (vinyl chloride) /poly (ethyl methacrylate) blend-based polymer electrolytes

“…The conductivity of the gel polymer electrolytes could be calculated by substituting the value of bulk resistance in the equation σ = t / R b .A where t is the thickness of the film and A is the electrode area. The depressed semicircular portion noticed in the high frequency region of the impedance spectrum of IL8 signifies that the greater part of charge carriers contributing towards the total conductivity of the electrolyte medium are ions and that the inclined spike appearing at the lower frequency regime of the impedance plot may be attributed to double-layer capacitance with the zinc ion blocking electrode (SS/GPEs/SS) configuration [24]. The observed variations of room temperature ionic conductivity of gel polymer electrolyte films as a function of different concentrations of EMIMTFSI are depicted in Fig.…”

“…Hence the obtained gel polymer electrolyte IL8 was found to be a self-standing translucent film with the maximum ionic conductivity of 1.10 × 10 −4 Scm −1 without any noticeable leakage of ionic liquid as confirmed form the cross-sectional SEM image of IL8. There has been no obvious phase separation in all the SEM images of gel polymer electrolytes signifying the complete compatibility of polymer blend system with the ionic salt and plasticizer EMIMTFSI [24,45].…”

Morphology and Thermal Properties of Nano‐Blends Based on Cellulose Acetate Butyrate, Poly (ethyl methacrylate) and An Organically Modified Algerian Bentonite

“…The FTIR spectra of PEMA/CAB/OMMT systems show absorption bands located at 1715–1764 cm −1 and 1100–1300 cm −1 , attributed to the vibration of CO and CO of PEMA and CAB. The peaks observed at 2800–2900 cm −1 and 1450–1480 cm −1 are associated to the vibrations of CH 3 and CH 2 groups of PEMA …”

Effects of ceramic filler in poly(vinyl chloride)/poly(ethyl methacrylate) based polymer blend electrolytes

“…The weak intensity peak appearing at 507 cm -1 is assigned to the stretching mode of ClO 4 - [13]. indicates that the majority of the current carriers in the electrolyte medium are ions and that the total conductivity is mainly due to ion conduction [14]. The bulk resistance of the electrolyte was measured by extrapolating the intercept of this plot on the real axis.…”
