Abstract:

Under the dual?carbon goal,alkali metal batteries with high specific energy have received widespread attention,but the growth of dendrites during battery cycling will bring serious safety hazards.The new two?dimensional material MXene has excellent electrical conductivity,sufficient interlayer space,and stable layered structure.It has application value as metal anode protective material.Firstly,the different preparation methods of MXene were introduced,and then the application status of MXene in the field of metal anode protection were analyzed and evaluated.Among them,the three main types of MXene and alkali metal composite methods(rolling method,melt pouring method,electrodeposition method) were summarized,and it was pointed out that the current methods generally had disadvantages such as easy oxidation,difficult operation,and difficulty in large?scale production.Finally,it was proposed that the development of MXene should refer to the development strategy of graphene materials,and make more use of its surface active functional groups and sheet structure to build independent current collectors or protective layers to obtain better cycle performance.

Key words: dual?carbon goal, alkali metal battery, high specific energy, MXene
