The energy storage performance of one of the lightest-known MXenes, Ti 2 CT x (MX) combined with carbon nanospheres (CNS) has been investigated as a symmetric electrode system in an aqueous electrolyte (1 M Li 2 SO 4 ). The energy storage properties were interrogated using cyclic voltammetry (CV), galvanostatic cycling with potential limitation (GCPL), electrochemical impedance spectroscopy (EIS) and voltage-holding tests. The combined material (MX/CNS) demonstrated a higher specific capacity compared to each of the individual components. The material was fabricated with relatively high and low mass loadings, assembled into a symmetric device and performance compared. Specific capacitance, specific power and specific energy for the lower electrode mass loading of 180 F·g −1 , 37.6 kW·kg −1 and 14.1 W·h·kg −1 were all higher than 86 F·g −1 , 20.1 kW·kg −1 and 6.7 W·h·kg −1 for the higher mass loading. A wide voltage window of 1.5 V was obtained, but with limited long-term cycling behavior, suggesting the need for future improvement. Mathematical modelling and simulation of the supercapacitor showed good correlation with the experimental results, validating the model. The results reveal the potential of the Ti 2 CT x to be employed as a viable energy storage system for lightweight applications. As part of the increasing role of clean energy technologies, electrochemical capacitors (ECs) are continuously evolving components that contribute to meeting the demands of electronic apparatuses and systems and are projected to be even more significant in the future.1 In 2011, Gogotsi and co-workers, 2 first synthesized a two-dimensional (2-D) layered material called MXene, by selectively etching aluminum (Al), using hydrofluoric acid (HF) from the MAX phase material. MAX phase materials are layered ternary carbide and nitride materials with the general chemical formula of M n+1 AX n (where 'M' represents an early transition metal, 'A' represents a group IIIA or IVA element, 'X' is C and/or N, and n may equal 1, 2, or 3). There are more than 70 different MAX phase compositions currently known. 3,4 MXenes are formed when the 'A' element is etched out of the MAX phase material, and subsequently have a general formula of M n+1 X n T x (where T represent surface functional groups such as F, OH or O, and x is the number of functional groups that are attached to the surface following the etching process).5 This newly discovered family of materials has similar properties to graphene with good electronic conductivity and different surface terminations enabling the possibility to manipulate their properties to fit different applications. 2-D materials potentially have large electroactive surfaces and therefore attract research attention. MXenes are currently studied, both theoretically and experimentally, as potential electrode materials for energy storage devices such as batteries [6][7][8][9][10][11][12][13][14][15][16] and ECs 9,14,17-32 as well as other uses. 33,34Although the MXene materials do not possess such a high surface ...

“…[146,147] The CNTs are used to compound with an MXene, with CNTs interposed as an spacer between MXene layers to prevent MXene films from readhering. Thus far, the Ti 3 C 2 T x /CNT composite [70,75,126,149] and the Nb 2 CT x /CNT composite [150,151] are the most common MXene/CNT composites.

“…When an all-phenyl complex (APC)-LiCl was used as the electrolytic solution, battery capacities have been found to be significantly larger than with all-phenyl complex as the electrolyte (Figure 9b). [149] MXenes can also combine high-temperature materials, which are used in fuel cells, such as the polybenzimidazole/Ti 3 C 2 T x composite. The larger radius of Mg 2+ causes Mg 2+ to move slower than a Li + ion; therefore, the Li + ion inserting into the electrodes was the main contributor to the capacitance.…”

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.
