Abstract: Under the pressure of increasing global energy demand and escalating environmental issues,developing efficient and sustainable energy storage materials has become an urgent priority in current scientific research. Two-dimensional MXene materials, characterized by their unique layered structure, abundant surface functional groups, and adjustable layer spacing, have demonstrated significant potential in energy storage applications. This paper systematically reviews the latest advances in two-dimensional MXene research in electrochemical energy storage. It emphasizes the performance features, various preparation methods, and practical uses of Ti3C2Tx MXene in electrochemical energy storage, and also discusses future development trends, aiming to offer valuable guidance for related research fields.

Key words: Ti3C2Tx MXene; alkali metal-ion batteries; lithium-sulfur batteries; supercapacitors;flexible energy storage devices
