Peo-Based Polymer Electrolytes Containing Divalent Cations

Abstract

AbstractPoly(ethylene oxide) is a non-aqueous solvent which can dissolve high concentrations of a wide variety of monovalent and divalent cation salts. The resulting solutions are generally heterogeneous mixtures of crystalline and amorphous regions. The amorphous components have relatively high ionic conductivities, and PEO ‘quasi-solid’ electrolytes and related polymer materials are arguably a new class of electrolyte, with properties in between those of true solids and true liquids. This paper briefly discusses the preparation and properties of PEO electrolytes containing Mg(II), Zn(II), and Pb(II) salts.
