Description
Summary:The system formed with poly(ethylene oxide) (PEO) and copper perchlorate was investigated over the Cu(ClO 4) 2 concentration range of 0–20 mol% by means of thermal and electrical measurements. The existence of entirely amorphous phases in a wide composition range was brought out. They generally have a fairly high ionic conductivity, comparable with that of polymer electrolytes containing Li +. Preliminary transport number measurement on PEO 17·Cu(ClO 4) 2 indicate a cationic transport number lower than 0.05, as previously found on a similar system with Pb.
