Figure 3. Structural analysis and electrochemical characterization of PTCDA electrodes. (A-C) Schematic illustrations of the PTCDA crystallographic structure, highlighting the active carbonyl reaction sites and π-interaction regions within the bc-plane and ab-plane configurations; (D) CV profile recorded at a scan rate of 0.3 mV/s. (E) GCD curves obtained at various current densities; (F) Long-term cycling stability and coulombic efficiency evaluated at a specific current of 1.6 A/g. Reprinted with permission from Ref.^[26].
