摘要：

The effect of propylene carbonate on the PEO-LiCF3SO3 system was studied using infrared spectroscopy and ionic conductivity measurements. It has been observed that large amounts of propylene carbonate tend to decrease the degree of ionic association in polymer electrolytes, while the ionic conductivity increases by several orders of magnitude. Propylene carbonate interacts preferentially with the crystalline PEO phase relative to the (PEO)(3)LiCF3SO3 compound present in the PEO-LICF(3)SO(3) salt complexes.
