摘要

Li-CO2 batteries have garnered considerable attention due to their high energy density and their ability to utilize CO2 resources. However, the generation of insulating discharge product Li2CO3 severely weakens its cyclability, which places high demands on the cathode catalyst in Li-CO2 batteries. This study focuses on the development of Ru nanoparticles modified Mo2CTx as the cathode for Li-CO2 batteries, which is integrated with a high surface area, abundant active sites, and enhanced conductivity. As a result, the Ru@Mo2CTx cathode achieves a remarkable discharge capacity of 20995 mA·h·g−1 and a long cycle life of 1750 h. Additionally, density functional theory calculations provide further insights into the enhancement in absorptivity with Ru introduced onto Mo2CTx. This research paves the way for manipulating the catalytic activity of Mo2CTx and reducing the amount of usage of Ru in Li-CO2 batteries.
