Fig. 2. (a) Cyclic voltammograms of the clay electrolyte-based ESCs: RTIL at 60 mV/s and with a potential window of 5 V at different temperatures. (b) Cyclic stability of the RGO|Clay:RTIL|RGO capacitor at +200 oC with voltage windows of 2 V and 2.5 V. (c) Energy density versus power density of the RGO|Clay:RTIL|RGO capacitor at different temperatures with voltage windows of 2.0 V and 2.5 V. (d) Self-discharge profiles of the clay electrolyte-based ESCs: RTIL after charging to 2 V at constant current, maintaining the voltage at 2 V for 2 h, and then self-discharging the ESCs [90]. RGO is reduced graphene oxide (RGO). |
