摘要:

作为第一个被制备出来的MXene材料,Ti3C2Tx独特的二维层状结构使其具有良好的电学、光学、力学与热电等性质,在电化学储能领域展现出巨大的潜力。由于钠储量在地球中较为丰富且远高于锂储量,因此钠离子电池具有成本低等优点,成为近几年储能领域的研究热点。主要围绕Ti3C2Tx的特性,介绍了其通过插层、造孔等改性方法以及与单质、金属氧化物、金属硫化物结合构成复合材料作为钠离子电池电极材料的研究进展。最后指出应采取基于钠离子脱嵌或反应的更有针对性的优化方法提升总体的电化学性能。

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
