In Figure , we demonstrate the Ragone plot, depicting energy versus power density and comparison with other reported COFs. The energy density was estimated of ~607 Wh/kg by considering the reversible capacity and the average discharge plateau voltage, which is much higher than traditional commercial cathode materials such as LiMn₂O₄, LiCoO₂, and LiFePO₄, etc. We also achieved a significantly higher power density of ~60.72 W/kg. The higher energy density of HAT-DAB COF could play a crucial role in developing sustainable cathode materials for LIBs.
