The utilization of CO2 electrochemistry in energy storage has been considered as a promising power source due to its high theoretical energy density, high electrochemical potential, and ability to fix CO2. However, the low efficiency and poor reversibility of Li-CO2 evolution significantly impede the applications of Li-CO2 batteries. Herein, first-principles calculations were employed to investigate the 21 M1M2N4C active sites and explore the catalytic mechanism for the Li-CO2 evolution reaction. The adsorption and activation of CO2 on the thermodynamically stable DACs show that the TM atoms in M1M2N4C center sites with decreasing d-band center appeared to increase CO2 adsorption energy. Among the active sites, the MoMoN4C shows the most robust activation interaction with CO2 due to its high d-center and strong d-p orbital coupling. The implicit solvent CEP simulations verify the effects of dual-atom sites on the products' activities and selectivity by searching the possible reaction pathways toward the battery-discharging processes in the ether electrolyte. The decomposition of *Li2CO3 was simulated by the NEB calculations. The results prove that the MoMoN4C active site can boost the reaction dynamics and exhibit high reversibility for the Li-CO2 battery. © 2024, The Authors. All rights reserved.
