Copper transport properties in polymer electrolytes based on poly(ethylene oxide) and poly(acrylonitrile)

Transport properties of copper salts were studied in a solvent-free polymer electrolyte PEO–Cu(CF 3SO 3) 2 (where PEO is poly(ethylene oxide)) as well as in gel-type polymer electrolytes: polymer–solvent–CuX 2 (where X=Cl −, Br − or CF 3SO 3 −, polymer is PEO or poly(acrylonitrile) (PAN), solvent is...

Description
Summary:Transport properties of copper salts were studied in a solvent-free polymer electrolyte PEO–Cu(CF 3SO 3) 2 (where PEO is poly(ethylene oxide)) as well as in gel-type polymer electrolytes: polymer–solvent–CuX 2 (where X=Cl −, Br − or CF 3SO 3 −, polymer is PEO or poly(acrylonitrile) (PAN), solvent is dimethylsulfoxide (DMSO), sulfolane or propylene carbonate). Generally, low values of the cationic transference numbers ( T +≈0.02–0.08) for the polymer electrolytes were obtained. However, in the systems based on PAN plasticised with DMSO, the T + value increases significantly ( T +≈0.1–0.4); the highest value is reached in the system containing an excess of the Br − anions (PAN–DMSO–CuX 2–KBr, T +=0.4).
