Ion Transport in the Polymer Electrolytes Formed between Poly(ethylene succinate) and Lithium Tetrafluoroborate.

Abstract

Solid electrolyte complexes of poly(ethylene succinate), PESc, and LiBF4 were proposed from the melt and found to be the compound amorphous over the polymer repeat unit to salt formula unit range of 1:1 to 3:1. Preparations with larger amounts of salt contained a pure salt phase, and at salt concentrations below the 3:1 ratio, 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 a Gibbs-Adams-like excess entropy model. (Author)
