Fig. 5. (A) Characterization of the coloring and bleaching rate by measuring the switching time. Statistical results indicate a bleaching time of 0.75 seconds and coloring time of 1.82 seconds. Galvanostatic charge/discharge profile at (C) current densities from 0.01 to 0.1 mA cm⁻², and (D) 0.01 mA cm⁻².
