The Role of Solvating 12-Crown-4 Plasticizer on Dielectric
The complex of 12C4 with lithium cation lowers the activation energy of simultaneously conducting ions, increasing the simultaneously conducting ion content by >3×. This is consistent with an initial large increase in εs, which is higher than the prediction from the Landau and Lifshitz mixing rule, reflecting that ion aggregates observed in
Role of Different Plasticizers in Li-Ion Conducting Poly
Another key role of the plasticizer is that it increases the salt dissociation rate, and free ion charge carriers are available for conduction [210] [211] [212]. ... Electrolyte for Energy...
Effect of incorporation of different plasticizers on
Plasticizer facilitates the reduction of crystalline nature of the polymer matrix and also increases the polymer segmental mobility. It further results in greater ion dissociation which allows greater number of charge carriers for ion transport in the electrolyte.
Effect of incorporation of different plasticizers
This paper reviews the influence of different plasticizers/additives on the ion transport mechanism of Poly(vinyl alcohol) (PVA)-LiClO 4 polymer electrolytes since poly vinyl alcohol is a semi crystalline, synthetic biodegradable polymer and lithium perchlorate is one of the most moisture resistant lithium salts. This review also reveals the
Influence of plasticizer on ionic conductivity of PVC-PBMA
The incorporation of plasticizers into the polymer electrolytes increases the salt solvating power, free volume, flexibility of the polymer chain, enhance the amorphous nature of the polymer matrix, dissociate the ion pairs, and decrease the viscosity of polymer matrix leading to increase the ionic conductivity, electrochemical, stability, etc. [
- How does plasticizer affect ionic conductivity of polymer electrolytes?
- The incorporation of substantial amount of plasticizer in the polymer electrolytes enhances the ionic conductivity of polymer electrolytes. Plasticizer facilitates the reduction of crystalline nature of the polymer matrix and also increases the polymer segmental mobility.

- Do Plasticizers improve bulk conductivity and salt diffusion coefficient of polymer electrolytes?
- As expected, the plasticizers always improved the bulk conductivity and increased the salt diffusion coefficient of polymer electrolytes at the selected temperatures. The conductivity and the salt diffusion coefficients of sample electrolytes ranked identically in the order PL10PG>PL10EC>PL10PC>PL.

- Does plasticizer increase ionic conductivity of PEC/Li?
- The DSC and BES studies revealed that the addition of plasticizer decreased Tg and increased the ionic conductivity of PEC/Li. The dc conductivity ( σdc) values of PEC/Li increased with the addition of plasticizers, and the plasti-cizing effect of IL was larger than that of Gly.
