Figure 5. Electrochemical kinetics and redox reversibility. (A and B) Cyclic voltammetry (CV) curves of the conventional (A) and integrated 3D (B) electrodes at various scan rates, demonstrating superior redox reversibility and enhanced reaction kinetics in the 3D architecture. (C) Galvanostatic intermittent titration technique (GITT) profiles of the integrated 3D electrode, illustrating the equilibrium potential and overpotential during the dynamic processes. (D) Corresponding localized magnification of GITT curves during the discharge and charge processes, along with the calculated lithium-ion diffusion coefficients (DLi+) as a function of the state of charge/discharge.
