Summary: In recent years, Li-CO2 battery has become a research hotspot due to its high discharge capacity, energy density, and environmental benefits. However, the slow decomposition kinetics and difficulty in practical applications have been a challenge for researchers. In this study, copper polyphthalocyanine-carbon nanotubes composites (CuPPc-CNTs) were prepared as the cathode for reversible Li-CO2 batteries. The composites exhibited high discharge capacity, excellent polarization, and stable cycles. Copper polyphthalocyanine provided efficient catalytic sites and CO2 adsorption and activation, while carbon nanotubes contributed to the conductive network. The synergistic effect of the two compounds resulted in excellent catalytic activity.
