Bacto agar-based gel polymer electrolyte

Ionics, 2011
The biopolymer of a Bacto agar-based gel polymer electrolyte (GPE) was prepared by addition of NaI and I2 as redox couple. The prepared GPE was characterized using impedance spectroscopy and X-ray diffraction (XRD) in order to determine its electrical and structural properties, respectively.

Performance evaluation of PVdF gel polymer electrolytes

Ionics, 2002
A series of gel polymer electrolytes containing PVdF as homo polymer, a mixture of 1:1 Ethylene Carbonate (EC) : Propylene Carbonate (PC) as plasticizer and lithium-bistrifluoromethane sulphone imide [imide — LiN (CF3SO2)2] has been developed. Amounts of polymer (PVdF), plasticizer and the imide lithium salt have been varied as a function of their ...

Transport properties and microstructure of gel polymer electrolytes

Electrochimica Acta, 2000
Abstract Gel polymer electrolytes based on a copolymer poly(vinylidene fluoride (VdF)/hexafluoropropylene (HFP)) and a solution of ethylene carbonate (EC), diethyl carbonate (DEC) and as a salt LiN(CF 3 SO 2 ) 2 were prepared by changing the content of the polymer in the range 20–80 wt%. The effects of changing the salt concentration in the solution

7Li NMR measurements of polymer gel electrolytes

Solid State Ionics, 2002
Ion conducting polymer gels prepared from (ethylene oxide)n grafted methacrylates, ethylene carbonate (EC), gamma butyrolactone (gBL), and lithium hexafluorophosphate are studied by means of nuclear magnetic resonance spectroscopy. This study shows that there are at least two possible lithium sites with different mobility.

Polymer concentration dependence of the dynamics in gel electrolytes

Solid State Ionics, 2000
A polymer gel electrolyte sample with a gradually varying concentration of polymer have been examined by Raman and photon correlation spectroscopy. The gel consisted of poly(methyl methacrylate) complexed with a liquid electrolyte of lithium perchlorate salt in an ethylene carbonate and propylene carbonate solution.
