Fig. 3. — (A and B) GITT curves of the Li-O₂ batteries, which were acquired with a current density of 0.1 mA cm⁻² for 0.5 mAh cm⁻² and (A) a 60-min or (B) a 180-min time interval during the discharge and (B) charge processes. The insets are the enlarged images of selected areas. The concentration of PDI-TEMPO is 5 mM. (C and D) In situ DEMS analysis of the gas evolution during the charge process of Li-O₂ cell operation with (C) bare TEGDME electrolyte and (D) PDI-TEMPO electrolyte. The current density is 0.1 mA cm⁻².
