Consistent interest has lately been devoted to complexes formed between poly(ethylene oxide), PEO, and multivalent metal salts, since these polymer electrolytes offer challenging prospects for investigation, both in terms of definition of bulk transport properties of complicated, multiphase systems and in terms of the evaluation of practical application in advanced electrochemical devices, such as flat, thin-layer batteries and laminated electrochromic windows. In this work we present results obtained by complex impedance spectroscopy, cyclic voltammetry and differential scanning calorimetry on a series of PEO-Cu(CF3SO3)2 complexes prepared using different techniques. The data suggest that these complexes are copper ion conductors, although the overall transport mechanism is still unclear.

Abstract
Consistent interest has lately been devoted to complexes formed between poly(ethylene oxide), PEO, and multivalent metal salts, since these polymer electrolytes offer challenging prospects for investigation, both in terms of definition of bulk transport properties of complicated, multiphase systems and in terms of the evaluation of practical application in advanced electrochemical devices, such as flat, thin-layer batteries and laminated electrochromic windows. In this work we present results obtained by complex impedance spectroscopy, cyclic voltammetry and differential scanning calorimetry on a series of PEO-Cu(CF3SO3)2 complexes prepared using different techniques. The data suggest that these complexes are copper ion conductors, although the overall transport mechanism is still unclear.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
