Fig. 3. Electrochemical characterization using a half-cell setup and 1 M NaCl for AgNP-10CB and AgCl-20CNT electrodes. (A) Cyclic voltammetry at 1 mV s⁻¹, (B) galvanostatic charge/discharge at 0.1 A g⁻¹, (C) galvanostatic rate handling at 0.1–10 A g⁻¹, and (D) galvanostatic charge/discharge cycling stability at 0.25 A g⁻¹.
