Abstract
INVESTIGATIONS of the ionic conductivity of solids have been concentrated mainly on materials characterised by a purely ionic conductivity, such as AgI, RbAg4I5, and β-alumina, which have practical applications in the production of solid-state high energy–density batteries and other electrochemical devices1. In such cases a non-zero electronic contribution prevents the material from acting as a solid electrolyte: materials with mixed ionic–electronic conductivity can be used as electrode materials in electrochemical cells.
