(a) Cyclic voltammetry experiments performed at a scan rate of 0.03 mV·s−1 for three PTCDA electrodes containing a mixture of VGCF–SO3H and CNT–SO3H. (b) Comparison of rate capabilities for the same electrodes. Full and empty characters represent the Coulombic efficiency (%) and discharge capacity, respectively.
