Ionic Transport in Dilute Solid Polymer Electrolytes with Amorphous Structure

The ionic structure and transport properties of amorphous solid polymer electrolytes in the system copolymer of acrylonitrile and butadiene (40 : 60)—lithium hexafluoroarsenate (SPE) is studied in the region of small salt concentrations (up to 0.37 mol dm⁻³) at 298–368 K. In conditions studied, LiAsF₆ is dissociated predominantly to ions. Macroscopic models of ion transport are used to analyze the results of measurements of transport characteristics of SPE. Transport of anions free of the polymer matrix is realized activationlessly and resembles the Stokes drift in viscous media. Transport of cations solvated by electron-donating groups of the polymer turns possible only at temperatures in excess of a critical value (T _crit ≈ 333 K), when the statistical mean of molecules in the first coordination sphere of the lithium cation becomes less than four (which is the coordination number for solvation) and requires the overcoming of an energy barrier of ∼6 kJ mol⁻¹. Below T _crit, the SPE are unipolar anionic conductors.__________Translated from Elektrokhimiya, Vol. 41, No. 5, 2005, pp. 537–545.Original Russian Text Copyright © 2005 by Bushkova, Sofronova, Lirova, Zhukovskii.     

Specific ionic conduction in poly[oligo (oxyethylene glycol) methacrylate] (PMEO)–Li salt complexes under high‐pressure CO2

We measured the ionic conductivity of amorphous poly[oligo (oxyethylene glycol) methacrylate] (PMEO)–lithium salt complexes under a CO₂ pressure varying from 0.1 to 20 MPa. The pressure dependence of the conductivity was positive, and the conductivity was higher than that under an inert gas such as N₂. The ion‐conductive behavior has been modeled using both the Vogel–Tammann–Fulcher (VTF) equation and activation volume theory. The calculated parameters of the VTF equation show that CO₂ that had permeated into the PMEO matrix acts as solvent molecules to dissolve ions and lower the glass transition temperature at high pressures. The ionic conduction in PMEO complexes under high‐pressure CO₂ was scarcely related to the VTF parameters and activation volume equations. © 2005 Wiley Periodicals, Inc.

Development on Solid Polymer Electrolytes for Electrochemical Devices

Electrochemical devices, especially energy storage, have been around for many decades. Liquid electrolytes (LEs), which are known for their volatility and flammability, are mostly used in the fabrication of the devices. Dye-sensitized solar cells (DSSCs) and quantum dot sensitized solar cells (QDSSCs) are also using electrochemical reaction to operate. Following the demand for green and safer energy sources to replace fossil energy, this has raised the research interest in solid-state electrochemical devices. Solid polymer electrolytes (SPEs) are among the candidates to replace the LEs. Hence, understanding the mechanism of ions’ transport in SPEs is crucial to achieve similar, if not better, performance to that of LEs. In this paper, the development of SPE from basic construction to electrolyte optimization, which includes polymer blending and adding various types of additives, such as plasticizers and fillers, is discussed.
