Figure 3: Galvanostatic charge-discharge cycles for various graphite-based symmetric capacitors.
From: An aqueous electrolyte of the widest potential window and its superior capability for capacitors

(a) Charge and discharge cycles of a symmetric graphite-based capacitor with a CEM as the separator for10,000 times repetition; (b) Charge and discharge cycles of a symmetric graphite-based capacitor containing 20% of AC with a CEM, (c) with a MF and (d) with a FP as the separator (e). Charge and discharge cycles of a symmetric graphite capacitor containing 40% of AC with a MF as the separator. Other specific conditions are described in Table 1.
