Abstract With the surge of energy demand and aggravation of environmental problems, it is necessary to find a new environment-friendly energy sto-rage conversion device. Li-CO₂ battery has become a research hot spot because it can absorb and convert CO₂ into electricity. However, there are still some problems and challenges in Li-CO₂ battery, such as high overpotential and poor cycle performance. In this work, a kind of cathode/catalyst composite with ultrafine Ir nanoparticles uniformly loaded on nitrogen doped carbon nanotubes was synthesized for the first time by a simple solvothermal method, as a high efficiency cathode for Li-CO₂ battery. N-CNTs and ultrafine Ir nanoparticles were synergetic catalysis for which the 3D porous channel carbon skeleton structure cross-linked by N-CNTs ensured the transport of CO₂, ions and electrons and provides space for the deposition and decomposition of discharge products. The uniform distribution of ultrafine Ir nanoparticles improved the catalytic activity and regulated the morphology of discharge products. Therefore, the coulomb efficiency (72%), cycle life (160 cycles/1 600 h) and over potential (1.2 V) of Li-CO₂ battery with Ir/N-CNTs cathode catalyst were improved. Moreover, a simple schematic diagram of the nucleation mechanism of the discharge products was designed to show the formation and decomposition of Li₂CO₃ in the process of discharge and charge. This work inspires further research on catalyst design and provides a new idea for the development of high performance Li-CO₂ battery.

Key words： Li-CO₂ battery nitrogen-doped carbon nanotubets Ir nanoparticles catalyst
