(a) Galvanostatic discharge-charge voltage profiles of the electrode at different current densities.
Discharge-charge curves at various rates for (b) ACA-500-S@PANi-55% and (c) ACA-500-S-54ACA-500-S-54ACA-500-S-54ACA-500-S-54%
Discharge-charge curves at various rates for (a) ACA-500-S@PANi and (b) ACA-500-S cathodes.
After 45 discharge-charge cycles, the discharge capacity was still 690 mAh g−1.
Discharge-charge tests demonstrate that the resulting anode exhibits excellent cyclic stability.

(a) Discharge capacities and (b) discharge charge profiles at the various current rates.
After that, the discharge capacity can gradually resume along with the decrease of discharge/charge rate, showing capacity retention of 105% when lowering the discharge/charge rate to 0.2 C.
The electrochemical performances were acquired by discharge/charge cycles, rate cycles, cyclic voltammograms (CVs) and electrochemical impedance spectra (EIS).
