Cuprous ion-conducting glasses were prepared in the system CuCl- Cul-P_2O_5 These glasses had high ionic conductivities of 10^<-4> to 10^<-3> Scm^<-1> at room temperature. The conductivities of these glasses increased with increasing Cul content. The ratio Cu^+/ (Cu^+ + cu^<2+>) and the mobility of cuprous ion were measured to clarify the relation between Cul content and ionic conductivity. Both the ratio Cu^+/ (Cu^++ cu^<2+>) and the mobility of cuprous ions in these glasses increased with increasing Cul content. The conductivities of these glasses depended on both concentration and mobility of cuprous ions. Therefore, the conduction mechanism in these glasses was considered to be the diffusion path model. Glass transition temperature decreased with increasing CuI content. Infrared spectra and laser Raman spectra were measured to study structure of these glasses. The results showed that Cu^+, Cu^<2+>, Cl^-, and I- ions are not involved glass network but existed as simple ions in these glasses and these glasses shows open structure with increasing CuI content.
