STRUCTURAL AND IONIC CONDUCTIVITYSTUDIES ONPLASTICIZED PAN-SODIUM FLUORIDE POLYMER ELECTROLYTES FOR ELECTROCHEMICAL CELL APPLICATIONS
Ion conducting gel polymer electrolytes based on poly acrylonitrle (PAN) complexed with different weight percent ratios of Sodium Fluoride (NaF) salt were prepared by using solution cast technique. Structural characterization was performed using X-ray diffraction (XRD) technique and Fourier transforms infrared (FTIR) spectroscope technique. From the X-rd results increase in amorphous phase with...
متن کاملScott J. Lilley PhD thesis
The AsF6 anion, in the crystalline polymer electrolyte PEO6:LiAsF6, was replaced with the larger N(SO2CF3)2 anion. This produced an increase in the room temperature ionic conductivity of 1.5 orders of magnitude. It is believed that the enhancement is the result of the disruption of the electrostatic field around the lithium ions. The presence of the large and asymmetrical N(SO2CF3)2 ion creates...
متن کاملA Computer Simulation Study of Ionic Conductivity in Polymer Electrolytes
In this paper we present a computer simulation study of ionic conductivity in solid polymeric electrolytes. The multiphase nature of the material is taken into account. The polymer is represented by a regular lattice whose sites represent either crystalline or amorphous regions with the charge carrier performing a random walk. Different waiting times are assigned to sites corresponding to the d...
متن کاملLithium ion motion in a hybrid polymer: confirmation of a decoupled polyelectrolyte.
Ionic conductivity involving ion transport in polymer electrolytes has been a major focus of polymer battery research, and an important concept in understanding the mechanisms of ionic transport in polymers is the issue of the coupling between ion motion and the relaxation of the polymer segmental chain. This means that, in typical polymer electrolytes, ion transport is strongly coupled to the ...
متن کاملVapor-Pressure Osmometry and Conductivity Determination of Salting-Out Effects in Aqueous Surface-Active Ionic Liquid 1-Dodecyl-3-methylimidazolium Bromide Solutions
Systematic studies on the vapor-liquid equilibria (VLE) and conductometric properties of aqueous solutions of model surface-active ionic liquid 1-dodecyl-3-methylimidazolium bromide ([C12mim]Br) are performed in the absence and presence of a large series of electrolytes in order to achieve a deeper understanding about the molecular mechanism behind the specific salt effect on the aggregation be...
