Electrochemical Properties of Lithium Ion Conducting Solid Polymer Electrolytes
Abstract
In 1985 our laboratory initiated an investigation of the electrochemical reactions of molecular electron donor/acceptor species dissolved in solid and semi-solid solvents. Poly-ether polymer electrolytes were selected as the model solid and semi-solid solvents, and the redox species have included ferrocenes, metal bipyridine complexes, tetracyanoquinodimethane (TCNQ), and derivatives in which polyether chains have been attached to such species. The thrust of this investigation was firstly, to develop methodology for obtaining quantitatively interpretable electron transfer and mass transport rates of such molecular solutes in solid or semi-solid solvents, and secondly, to explore ways in which their solid state behavior differs from that familiar in fluid electrolyte solutions. This paper will draw together the essential aspects of the microelectrode-based solid state voltammetry methodology developed, and describe some of the special aspects of electron transfer and mass transport dynamics observed during this still on-going investigation.
