From: Effect of carbon black addition on thermal stability and capacitive performances of supercapacitors

Cyclic voltammetry curves of (a) the rGO SC and (b) the rGO-CB SC. Galvanostatic charge/discharge curves of (c) the rGO SC and (d) the rGO-CB SC. Specific capacitance (e) plots and IR drops (f) of the rGO SC and the rGO-CB SC at various current densities.
