Ion-Pairing in Polyether Solid Electrolytes and Its Influence on Ion Transport.

Abstract

Vibrational spectroscopic and conductivity data are presented for complexes of NaBF4 and NaBH4 with poly(ethylene oxide). These studies indicate that extensive contact ion pairing occurs in the NaBH4 complex but not in the NaBF4 complex. As a result the ionic conductivity is considerably lower in the NaBH4 complex, due to trapping of the mobile sodium cations by the anion. The effect of salt stoichiometry on the conductivity behavior is also reported. (Author)
