Electrochemical properties of various electrodes made of CNTs, graphene, and graphene/CNT composite. (a) Cyclic voltammetry curves in the aqueous KCl electrolyte at a scan rate of 10 mV/s. (b) Cyclic voltammetry curves in 1 M TEABF4/PC electrolyte at the same scan rate of 10 mV/s. (c) Galvanostatic charge/discharge curves in the aqueous electrolyte at a charging current of 500 mA/g. (d) Galvanostatic charge/discharge curves in the organic electrolyte at the same charging current of 500 mA/g (Reproduced with permission of [29]. Copyright Royal Society of Chemistry, 2011).
