Electrical, structural and thermal characterization of Cu2O substituted AgI-(Cu2O)x (Ag2O)1 − x-V2O5 glassy superionic system

► A new glassy superionic system AgI-(Cu2O)x (Ag2O)1-x-V2O5 is synthesized. ► Cu2O substitution leads to significant enhancement in the ionic conductivity. ► The conductivity rise is attributed to enhancement in the ionic mobility.
