The cover picture shows the motion of ions in polymer electrolytes formed by dissolving a salt in a solvating polymer, poly(ethylene oxide). Interestingly, with a family of anions chosen for their high extent of dissociation, perfluoroalkylsulfonamides of increasing chain length, the relative speed at which the cation and anion move remains constant. This is in complete contradiction to conventional electrochemistry in dilute solutions, where the mobilities correlate inversely with ion size.
