“…[106] The thickness difference of Ti 3 C 2 T x flakes leads to different resistances and transmittances; therefore, their optoelectronic properties are interesting. Moreover, the performance of the MXenes can be improved by making peculiar morphologies (e.g., hollow MXenes [121] ), changing the local structure of MXenes (e.g., doping by other atoms [122,123] ), modifying surfaces (e.g., heat treatment [38] ), increasing the MXene layer spacing (e.g., inserting cations or organic molecules [48,124] ), etc. [107,108] It is well known that titanium hydroxide and/or titania show good photocatalytic activities.…”

The family of 2D transition metal carbides, nitrides, and carbonitrides (collectively called MXenes) is rapidly studied since the initial synthesis of Ti3C2Tx (MXene). The surface of MXenes etched by hydrofluoric acid has hydrophilic groups (F, OH, and O), which leads the surface to be negatively charged. Consequently, the negatively charged surface can facilitate the compounding of MXenes with other positively charged materials and prevent MXenes from aggregating with some negatively charged substances, thus promoting the formation of a stable dispersion. The MXene‐based composites have better electrochemical performance than both precursors due to synergistic effects. This review elaborates and discusses the development of MXene‐based composites. It is aimed to summarize the various methods of fabricating MXene‐based composites. The applications of MXene‐based composites in batteries and supercapacitors are presented along with analysis of their excellent electrochemical performances. Finally, the authors propose the approach for further enhancing the electrochemical performances of MXene‐based composite electrode materials.

Although Ti 3 C 2 MXene has shown great potential in energy storage field, poor conductivity and restacking between MXene flakes seriously hinders the maximization of its capacitance. Herein, a new strategy to solve the problems is developed. Gallery Al atoms in Ti 3 AlC 2 are partially removed by simple hydrothermal etching to get Ti 3 C 2 T x reserving appropriate Al interlayers (Ti 3 C 2 T x @Al). Ti 3 C 2 T x @Al keeps stable layered structure rather than isolated Ti 3 C 2 T x flakes, which avoids flake restacking. The removal of partial Al frees up space for easy electrolyte infiltration while the reserved Al as "electron bridges" ensures high interlayer conductivity. As a result, the areal capacitance reaches up to 1087 mF cm −2 at 1 mA cm −2 and over 95% capacitance is maintained after 6000 cycles. The all-solid-state supercapacitor (ASSS) based on Ti 3 C 2 T x @Al delivers a high capacitance of 242.3 mF cm −2 at 1 mV s −1 and exhibits stable performance at different bending states. Two ASSSs in tandem can light up a light-emitting diode under the planar or wrapping around an arm. The established strategy provides a new avenue to improve capacitance performances of MXenes.
