Fig. 7. (a) Current response from 300 mV applied potential to 14 (red) and 19 (blue) in a symmetric lithium metal cell. (b) AC impedance spectra collected during 24 hour operation of Li(s)|electrolyte|Li(s) symmetric cells. Top: Polymer 14. Bottom: Polymer 19. Red data represents impedance spectra taken without constant applied voltage. Blue data represents spectra taken with 300 mV applied voltage. Green data represents the final spectrum taken after the experiment.
