Figure 5. Cycling of Swagelok Li-O2 cells at 60 °C. (A and B) Potential against current density, where the potential plotted is the average potential of the cell reached at each current density during a dynamic discharge (three cell average). (C) Discharge-charge profiles at 0.05 mA·cm-2 and galvanostatic cycling at ± 0.05 mA·cm-2 with limited capacity (0.2 mAh·cm-2). (D) Discharge capacity retention. Selected potential profiles of (E) Iongel-TFSI and (F) Iongel-FSI cells.
