CV curves of the Cu negative electrode at different scan rates in (a) Cu−Cl and (b) Cu−H2O electrolytes. c The b values corresponding to the three oxidation peaks in a and b. d Capacitive contributions at various scan rates. e GCD curves in Cu−Cl electrolyte at various current densities. f GCD curves in Cu−H2O electrolyte at various current densities. g Rate performance in Cu−Cl and Cu−H2O electrolytes. h Long-term stability in Cu−Cl and Cu−H2O electrolytes at 20 mA cm−2. The electrochemical tests were conducted in a three-electrode cell consisting of a carbon felt working electrode, a Pt plate (1 × 1 cm) counter electrode, and an SCE reference electrode.
