However, the high charge overpotential, unstable cycling, and incomplete understanding of the electrochemical process limit its advancement for practical applications. Herein, we develop a Li-CO<sub>2<\/sub> battery by designing a bimetallic ruthenium-nickel catalyst onto multi-walled carbon nanotubes (RuNi\/MWCNTs) catalyst as cathode by solvothermal method, which exhibits a lower overpotential of 1.15 V and a discharge capacity of 15,165 mAh g<sup>-1<\/sup> with outstanding coulombic efficiency of 97.4 %. The battery can also operate at high rates and have a stable cycle of more than 80 cycles at a current density of 200 mA g<sup>-1<\/sup> with a fixed 500 mAh g<sup>-1<\/sup> capacity. Furthermore, Mars exploration is made feasible with the Li-CO<sub>2 Mars<\/sub> battery composed of the RuNi\/MWCNTs as cathode catalyst, which performs very similarly to that of pure CO<sub>2<\/sub> atmosphere. This approach may simplify the process of developing high-performance Li-CO<sub>2<\/sub> batteries to achieve carbon negativity on Earth and for future interplanetary Mars missions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>DOI: 10.1002\/cssc.202300734 Authors: Keerti M.
