Abstract
Cu+‐ion‐conducting glasses were prepared in the pseudo‐binary system CuI‐Cu2MoO4. These glasses have high ionic conductivities at room temperature in the range 10−1 to 10° S·m−1, which are 10 to 20 times greater than those of the Ag+‐ion‐conducting glasses with the same iodide contents in the system AgI‐Ag2MoO4. The conductivities increase with increasing CuI content. The increase in the conductivity can be explained in terms of a decrease in the activation energy for conduction. The electronic conductivity was measured by the Wagner polarization method and indicates that the transport number of Cu+ ions in those glasses is 0.9996 and larger.Keywords
