Electrochemical performance of APE-700 measured in a two-electrode system: (a) CV curves at different scan rates from 5 to 100 mV·s−1; (b) GCD curves at different current densities from 0.2 to 10 A·g−1; (c) cycle stability at a current density of 2 A·g−1 in 6 M KOH solution; (d) EIS before and after the cyclic stability test, an enlarged view in the high-frequency region is shown in the inset.
