Abstract:
Cu+ conducting glasses were prepared in the Cu2O-MoO3-P2O5 system. These glasses, known for their high
ionic conductivity, are promising in applications to solid state batteries and other energy storage devices.The amorphous
state of the samples has been confirmed through X-ray diffraction. The electronic conductivity was measured by means of
the Wagner polarization method. Colloidal graphite has been used in order to maintain a reducing medium, necessary to
stabilize the copper at the lower state of valence. The variations of the conductivity, activation energy and transference
number vs. the graphite amount has been investigated. The records show a constant rise until 1 % wt. graphite. Once this
amount has been exceeded, the conductivity drops bellow that of the sample without graphite.
