Gel polymer electrolytes (GPEs) were prepared by dissolving lithium tetrafluoroborate (LiBF4) salt, poly(methylmethacrylate) (PMMA) polymer and distinct non-volatile solvents propylene carbonate (PC), and -N,N-dimethylformamide (DMF) in single as well as binary solvent mixtures. Ionic conductivities of 8.93 mS/cm and 6.68 mS/cm at 25 °C have been obtained for gel polymer electrolytes for 10 wt% PMMA...
Ionic conductivity of polymer electrolytes obtained by complexation of trifluoromethanesulfonic acid (HCF3SO3) (triflic acid) with polyethylene oxide (PEO) has been found to increase with the addition of dimethylacetamide (DMA) as plasticizer. The increase in conductivity has been explained to be due to dissociation of ion aggregates with the addition of plasticizer, which has also been supported...
The addition of polymer to liquid electrolytes containing trifluoromethanesulfonic acid (HCF3SO3) in propylene carbonate (PC) has been found to result in an increase in conductivity of gel electrolytes. The increase in conductivity has been observed to be due to the dissociation of ion aggregates present in the electrolytes which has also been supported by Fourier transform infrared studies. The maximum...
