Scaling behavior and nearly constant loss effect in AgI–LiPO3 composite glasses

摘要: Abstract xAgI–(1 − x)LiPO 3 composite glass electrolytes were prepared by melt quenching technique using a twin roller assembly operated at 2000 rpm. The glasses with x   0.2, micron size cluster particles of γ -AgI nanocrystallytes, embedded in matrix observed. This was confirmed XRD and SEM studies. conductivity increased several orders magnitude comparison to pure LiPO glasses. Maximum ~ 10 − 3  S/cm found for x = 0.5 composition. FTIR studies suggest that AgI acts as plasticizing agent which reduces the polymeric chain lengths phosphate In addition provides silver ions contribute total ionic conductivity. It shown Summerfield scaling  0.2 obeyed it deduced these conduction is predominantly due any lithium if all negligible. Nearly constant loss (NCL) effects observed low (x  However no NCL effect high content expected presence only has been .
