Status and Prospects of MXene-Based Lithium-Oxygen Batteries: Theoretical Prediction and Experimental Modulation

The consumption of fossil fuels has contributed to global warming and other problems. It is urgent to exploit progressive, low-cost, and environmentally friendly energy storage devices with super high energy density. Rechargeable lithium oxygen batteries (LOBs) with a high theoretical energy density (approximate to 11400 Wh kg(-1)) are one of the most promising chemical power supplies. MXenes have recently emerged in energy storage and conversion due to their superior conductivity and adjustable structural properties. Here, this paper summarizes the latest research progress in MXene-based materials in the cathode, anode, separator and electrolyte of LOBs and emphasizes the significance of high conductivity and surface functionalization strategies in the theoretical design and experimental modulation, which promote electrode reaction kinetics and increase the cyclability of LOBs. It also summarizes the prospects and challenges of MXene-based LOBs and proposes novel strategies to promote battery performance, inspiring the future progress of MXene-based materials in designing high-performance LOBs.
