Electrochemical properties of the DCNQ/PPy composite and the reference samples. (a) Cyclic voltammograms of the DCNQ/PPy composite (i, red line), commercial PPy (ii, black line) and commercial DCNQ (iii, blue line) at a scan rate of 1 mV s−1. (b) Charge–discharge curves of the DCNQ/PPy composite at a current density of 1.0 A g−1 (i, black line) and 5.0 A g−1 (ii, red line). (c) Specific capacity of the DCNQ/PPy composite (filled circles), the mixture of the DCNQ nanocrystals and the commercial PPy microfiber (filled squares), the mixture of the bulk DCNQ and the commercial PPy (filled triangles), the DCNQ nanocrystals (open squares) and the bulk DCNQ crystals (open triangles) at different current densities. The reproducibility of the electrochemical properties of the DCNQ/PPy composite was verified using five samples (Supplementary Figure S5 in the Supplementary Information).
