Characteristics of PEMA/PVdF-HFP blend polymeric gel films incorporated with lithium triflate salt in electrochromic device

GelatinnZn(CF3SO3)2 Polymer Electrolytes for Electrochromic Devices

“…The anodic peak related to the oxidation process (bleaching) changed from −0.2 V to 0 V upon applied voltage (Figure 8). The low current values of 10 µA cm −2 for the cathodic and anodic processes observed in the present work were comparable to those of the ECDs with poly(ethylmethacrylate)/poly(vinylidenefluoride‐ co ‐hexafluoropropylene) blend polymeric gel electrolytes with LiCF 3 SO 3 salt (PEMA/PVdF‐HFP) 28 although, the ionic conductivity values of the electrolyte with zinc triflate are five orders of magnitude lower when compared with PEMA/PVdF‐HFP electrolyte. However, in both studies similar values of the color/bleaching transmittances of about 15 % were obtained.…”

Headway in rhodanide anion based ternary gel polymer electrolytes (TILGPEs) for applications in rechargeable lithium ion batteries: an efficient route to achieve high electrochemical and cycling performances

“…The intensity of the ve bands of TILGEs keeps increasing with increasing content of electrolyte mixture thereby conrm the presence of both anions and cations of electrolyte mixture in PVdF-co-HFP matrix. The results obtained are in concurrent with the result reported earlier by Arof et al 46,47 Fig . 6 shows the FTIR spectrum in two different regions namely 3000-2800 cm À1 and 980-840 cm À1 of pristine PVdF-co-HFP and TILGPEs containing different weight percentage of electrolyte mixture.…”

Ionic conductivity and relaxation studies in PVDF-HFP:PMMA-based gel polymer blend electrolyte with LiClO4salt

“…7 The blending of the polymer increases amorphicity or can hinder the crystalline nature. 15,16 The plasticizer is a low molecular weight organic solvent which has the ability to dissociate the salt and maintain the liquid state within the polymer matrix. 15 It also helps increase the amorphous phase in the polymer electrolyte.…”

“…15,16 The plasticizer is a low molecular weight organic solvent which has the ability to dissociate the salt and maintain the liquid state within the polymer matrix. 15 It also helps increase the amorphous phase in the polymer electrolyte. The dissociation increases the number of free mobile ions which contribute toward the conductivity of polymer electrolyte.…”
