Abstract:

As the first prepared mxene material,Ti3C2Tx has excellent electrical,optical,mechanical and thermoelectric prop-erties due to its unique two-dimensional layered structure,showing great potential in the field of electrochemical energy stor-age.Due to the abundance of sodium in the earth and much higher than that of lithium,sodium-ion battery has the advantages of low cost and has become a research hotspot in the field of energy storage in recent years.Based on the properties of Ti3C2Tx,the modification methods of Ti3C2Tx,such as intercalation and pore-forming,and the research progress of composite materials composed of monomers,metal oxides and metal sulfides as electrodes materials for sodium-ion batteries were introduced.Finally,it was pointed out that more targeted optimization methods based on sodium ion deintercalation or reaction should be adopted to improve the overall electrochemical performance.

Key words: MXene, Ti3C2Tx, modification, composite material, sodium-ion batteries
