Effect of ethylene carbonate addition on ion aggregates, ion
The presence of (EC) as the plasticizer can promote ionic dissociation. EC has higher dielectric constant (89.1) with higher donor number (16.4) and higher boiling temperature (248 °C) as compared to other plasticizers such as polycarbonate (PC) or polyethylene glycol (PEG) [ 14 ].
Effect of plasticizer on the ion-conductive and dielectric
Solid polymer electrolytes consisting of CO 2 -derived poly (ethylene carbonate) (PEC), LiPF 6, and plasticizers (glycerol or 1-ethyl-3-methylimidazolium bis (trifluoromethane sulfonyl)imide,...

Introduction Solid State Ionics is an interdisciplinary branch of science and technology that deals with the study of solids having high ionic conductivity -value (10 1-10-4 S/cm) which are generally known as superionic conductors or fast ion
Effect of plasticizers on ionic conductivity and dielectric
In this paper, we report the effect of different plasticizers, such as poly ethylene glycol, propylene carbonate, ethylene carbonate and dimethyl carbonate on the ionic conductivity and dielectric relaxation of PEO-LiClO 4 solid polymer electrolytes. The highest ionic conductivity is obtained for polymer electrolyte plasticized with poly
Influence of plasticizer on ionic conductivity of PVC-PBMA
The incorporation of ethylene carbonate into the polymer matrix is found to increase the ionic conductivity by increasing the amorphicity, enhancing the solvation of lithium salts, and spreading the lithium ions evenly in the polymer electrolytes due to its high dielectric constant and low viscosity [1.93 cP (centipoise)] [ 25, 26 ].
