Electrochemical synthesis of polyaniline-Ni-Co hybrid structures on titanium substrates for ultrahigh-capacitance supercapacitor electrodes.

87 The areal specific capacitance, calculated from the CV curves, exhibited a decreasing trend with increasing scan rate (shown in Fig. 5b ), from 2819.4 mF cm −2 at 5 mV s −1 to 313.7 mF cm −2 at 200 mV s −1 .
