Next, we are interested in assessing whether interchain cation hopping via continuous ligand exchange is an important transport mechanism for cations. We suspect cation hopping might be important, because the MSD plots show that chain motion is 2-3 times slower than Li + diffusion, indicating that cation diffusion, on this timescale, is not solely driven by the segmental motion of the polymer. The hopping behavior varies considerably among individual cations. In Figure and Figure we show the behavior of two example ions:
