Fig. 4: Device-level electrochemical performance.
A Long-term cycling at 10 A g−1 for symmetrical pouch cells with an areal loading of 1.9 mg cm-2, cycled at room temperature, over 50,000 cycles. The experiments are conducted at room temperature using three cells to confirm reproducibility. B Aggressive voltage float tests at 2.7 V of TEABF4 and SBPBF4 devices as further illustrates the longevity of the M-rGO devices over a 240 h testing period. The voltage float test is carried out once at room temperature. C Rate capability of cells with organic and ionic electrolyte at a practical active material loading of 6.1 mg cm-2. The experiments are conducted using three cells to confirm reproducibility and are carried out at room temperature.
