Fig. 3: Supercapacitor performance of MGC in EMIMBF4 electrolyte.
From: Sub-millisecond lithiothermal synthesis of graphitic meso–microporous carbon
A CV curves from 1 V/s to 100 V/s of MGC, which can sustain high scan rates, like electrolytic capacitors. B GCD curves at 0.1–200 A/g for MGC. C Variation of specific capacitance with charge/discharge current density of MGC and OMGC. D Nyquist plots for MGC and OMGC capacitors were taken at 3.5 V. The insets show magnification of the high-frequency region. E Phase angle versus frequency for MGC and OMGC. F Capacitance retention for MGC and OMGC capacitors cycled at 10 A/g to 3.5 V. G Variation of specific capacitance with charge/discharge current density of soft-package supercapacitor based on MGC and YP-50 in EMIMBF4. Their corresponding capacitance is 57 F and 52 F. Inset is the digital images of a soft-package device with an internal parallel structure.
