Abstract

There is considerable interest in plastic crystalline electrolytes which have good room temperature ionic conductivities and potential technological applications as membranes for devices such as batteries. Conductivity and X-ray absorption spectroscopy measurements have been used to study succinonitrile (1,2-dicyanoethane) doped with copper(I) and (II) triflate (trifluoromethanesulfonate) and TFSI (bis(trifluoromethane)sulfonimide). The conductivities at room temperature are reasonably good, particularly for Cu(I)TFSI doped at 1 mol%, where the conductivity is � 1�10 -3 S cm -1, which is consistent with previous work on this system. The Cu K-edge EXAFS in 1 mol% doped copper salts show that in all cases, whether Cu(I) or Cu(II), the ion is predominantly in a well-defined and ordered local environment. A tentative model of the conduction process is described that will account for this local structural information; however, the process is clearly complex even in these apparently simple systems. © by Oldenbourg Wissenschaftsverlag, München.
