Research progress of Ti3C2Tx-based composites application in electrode for supercapacitors

Abstract

Titanium carbide (Ti3C2Tx) as one of MXene materials, has unique structure, excellent conductivity, stability and superior electrochemical properties. It is often used as electrode material for supercapacitors. Based on the characteristics of the layered structure of Ti3C2Tx materials, the research progress in Ti3C2Tx based composite materials used for supercapacitor electrode was reviewed, and the structure, properties, preparation and electrochemical performance of Ti3C2Tx materials compounded with various types of materials through different technical means were emphatically described. The reasons for improving the properties of Ti3C2Tx matrix composites were summarized, including increasing the layer spacing, providing more active sites, and improving the toughness. Finally, the future research priorities of Ti3C2Tx matrix composites were pointed out, such as exploring new matrix parent phases, enriching etching methods, improving existing composites, and exploring more and more efficient composites.
