Abstract
The ionic conductivity,
σ, of mixtures of poly(ethylene oxide) (PEO) and lithium bis(trifluoromethanesulfone)imide (LiTFSI) was measured as a function of molecular weight of the PEO chains,
M, over the range 0.2–5000
kg/mol. Our data are consistent with an expression
σ
=
σ
0
+
K/
M proposed by Shi and Vincent [Solid State Ionics 60 (1993)] where
σ
0 and
K are exponential and linear functions of inverse temperature respectively. Explicit expressions for
σ
0 and
K are provided.
► PEO/LiTFSI electrolyte conductivity measured over wide molecular weight range ► Conductivity contributions arise from both segmental motion and chain diffusion. ► Explicit expressions provided for molecular weight dependence of conductivity
