Gel polymer electrolyte containing immobilized different types of salts (LiPF6, LiBF4, TEABF4) in aprotic solvents (PC, EC:DEC, EC DMC) were prepared by UV polymerization. Electrolytes were optimized to achieve suitable ionic conductivity (up to 7.5 mS/cm) and good mechanical stability.

Thermoreversible polymer gel electrolytes
Polymer, 1994Abstract Thermoreversible polymer gel electrolytes with ionic conductivities in the region of 10−3 S cm−1 (even at −20°C) have been prepared from a variety of commercially available polymers and organic solvents by gel casting from high-temperature solutions at polymer/solvent ratios down to 10 90 .

Proton conducting polymer gel electrolytes
Solid State Ionics, 1999Abstract Novel proton conducting gel electrolytes from poly(vinylidene fluoride)-dimethylformamide-H 3 PO 4 system are synthesized and characterized by impedance spectroscopy, infra-red spectroscopy and differential scanning calorimetry. Highly conducting (5×10 −4 S/cm at 20°C) colorless polymeric membranes are obtained in a relatively narrow ...

Ionic Liquid‐Polymer Gel Electrolytes
Journal of The Electrochemical Society, 1997New rubbery gel electrolytes have been prepared from room temperature ionic liquids and poly(vinylidene fluoride)‐hexafluoropropylene copolymer [PVdF(HFP)]. The ionic liquids employed in these preparations were 1‐ethyl‐3‐methylimidazolium salts of triflate and .

Polymer gel electrolytes for electrochromic devices
Electrochimica Acta, 1999Abstract Elastic and sticky polymer gel electrolytes were prepared by polymerisation of methacrylate resin to which solutions, containing LiBF 4 and [(C 2 H 5 ) 4 N]BF 4 in various ratios in PC, were added, keeping the ionic strength constant. A concentration cell containing two polymer samples and two equal LiHg x electrodes was used for the ...

Cellulose triacetate‐based polymer gel electrolytes
Journal of Applied Polymer Science, 2009AbstractNew composite polymer gels were obtained from cellulose triacetate (CTA), N‐methyl‐N′‐propylpyrrolidinium bis(trifluoromethanesulfonyl)imide (Pyr1,3TFSI), and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI). Analysis by differential scanning calorimeter and scanning electron microscope showed that the ionic gel consisting of CTA, Pyr1,3TFSI,

Gel polymer electrolytes based on PMMA
Electrochimica Acta, 2001New polymer gels (based on PMMA/PC) containing Li, Na, Mg, and Zn perchlorates were prepared. The conductivity of gels containing cations of smaller ionic radii (Li and Mg) is lower than that of the others.

Gellan Gum-LiI Gel Polymer Electrolytes
Molecular Crystals and Liquid Crystals, 2012Gellan-based polymer electrolytes (PEs), doped with lithium iodide (LiI), were prepared and their electrical properties were characterized. The samples are thermally stable up to 234°C and exhibit ionic conductivity of 3.8 × 10−4 S/cm at room temperature for the sample doped with 40 wt% of LiI. Addition of 10 wt% of glycerol promotes an increase of the
