Fig. 6. Electrophoretic mobilities (filled symbols) from eNMR and apparent mobilities (open symbols) from PFG-NMR of the GPE and the liquid electrolyte: Li (blue triangles), TFSA (red circles) and BoB (black squares) at 20 °C measured by ⁷Li, ¹⁹F and ¹³C NMR respectively. Errors are calculated by error propagation.
