Figure 2. Electrochemical performance and kinetic characterizations of o-PDI, m-PDI, and p-PDI electrodes. (A-C) CV tests at 1 mV/s. (D) GCD curves. (E) CV curves at various scan rates and (F) The corresponding b values derived from i = avb. (G) Pseudocapacitance ratio of m-PDI at 1 mV/s. (H) Contribution of pseudocapacitance at different scan rates. (I) Linear relationship between i and the square root of v.
