Title: Solid-state ionics: a new high ionic conductivity solid electrolyte Ag/sub 6/I/sub 4/WO/sub 4/ and use of this compound in a solid-electrolyte cell

Abstract

A new high ionic conductivity solid Ag/sub 6/I/sub 4/WO/sub 4/ has been found in the system AgI-Ag/sub 2/WO/sub 4/ at ambient temperature. This compound has a silver ion conductivity of 0.047 (ohm.cm)/sup -1/ at 25/sup 0/C and an activation energy for conduction of 3.6 KCaL/mole between 20/sup 0/ and 293/sup 0/C. The transport number measurement using Tubandt's method shows that the transport number of silver ions in this compound is 1.00 within the experiment error. An Ag/Ag/sub 6/I/sub 4/WO/sub 4//I/sub 2/ solid-electrolyte cell shows an open-circuit voltage of 637 MV which agrees well with the value of 686.7 MV calculated from deltag degrees of the cell reaction at 21/sup 0/C. Characteristics of the solid-state cells using Ag/sup 6/I/sub 4/WO/sub 4/ as the electrolyte have been investigated. The phase diagram of the system AgI-Ag/sub 2/WO/sub 4/ has been determined also. 14 references.
