摘要：

Doping of lithium salts into the plastic crystal phase of succinonitrile does significantly increase ionic conductivity. This paper investigates the effect of anion (TFSA, Tf and BF4) on the conductivity and diffusion of the mobile species using impedance spectroscopy and NMR. Room temperature conductivities up to 2.1 x 10(-4) S cm(-1) were obtained with 1 mol% lithium bis(trifluoromethanesulfonyl)amide in succinonitrile. Pulse field gradient NMR has shown that in all three systems investigated, both cation and anion are mobile in this lattice. (C) 2004 Published by Elsevier B.V.
