Abstract

Solid electrolyte complexes of poly(ethylene succinate), PESc, and LiBF4 were prepared by heating the salt with the molten polymer. The complexes were completely amorphous over the concentration range 1:1 to 3:1 polymer repeat units: metal cation. At salt concentrations above the 1:1 composition, a salt phase was present, and at salt concentrations less than 3:1, free crystalline polymer was observed. Within the 1:1 to 3:1 concentration range, increasing salt concentration was accompanied by decreasing conductivity, and increasing glass transition temperatures.This behavior is discussed in terms of free-volume theory, with dynamical corrections.
