“…Building upon this method, Ti 3 C 2 T X has also been oxidised in the presence of alkali hydroxides to produce Li 4 Ti 5 O 12 and Nao .23 TiO 2 composites (Figure a, b) . Under ambient alkali conditions, NaO 23 TiO 2 formed on the surface of Ti 3 C 2 as nanobelts, which sat between MXene layers like filling in a sandwich (Figure a), preventing agglomeration and allowing a capacity comparable to the theoretical capacity of sodium titanate (178 mAh g −1 ) to be retained after 4000 cycles at 5 A g −1 .…”

2D transition metal carbides and nitrides (MXenes) are electrochemically active materials capable of exhibiting pseudocapacitance. Multilayer MXenes are similar to graphite, but with larger interlayer spacing and surface functionalities which allow them to readily disperse in water and undergo a range of reactions without compromising their electrical conductivity. The large interlayer spacing enables MXenes to readily intercalate large ions, and form composites with materials such as graphene, metal oxides, transition metal dichalcogenides and silicon, with which they make electrodes able to deliver exceptional capacities at high power rates over thousands of cycles. Research into MXenes for energy storage has grown exponentially since 2011, and it is now necessary, especially for readers new to the field, to review progress made in more specific areas. This critical review will therefore analyse the progress made in developing MXene‐based batteries, focusing solely on anodes developed for metal‐ion batteries such as Li‐ion, Na‐ion and K‐ion.

Tremendous efforts are devoted to developing advanced electrode materials with superior electrochemical performance, high energy density, and high power density for energy storage and conversion. Two‐dimensional (2D) materials, owing to their unique properties, have shown great potential for energy storage. Following the discovery of graphene, a new family of 2D transition metal carbides/nitrides, MXenes, derived from MAX phase precursors, have attracted extensive attention in recent years. The superior physical and chemical properties of MXenes include high mechanical strength, excellent electrical conductivity, multiple possible surface terminations, hydrophilic features, superior specific surface area, and the ability to accommodate intercalants. When applied as electrodes in lithium‐based batteries, MXenes have demonstrated excellent performance. In this progress report, the authors summarize the recent advances of MXenes and MXene‐based composites in terms of synthesis strategies, morphology engineering, physical/chemical properties, and their applications in lithium‐ion batteries and lithium–sulfur batteries. Furthermore, challenges and perspectives for MXenes and MXene‐based composites for lithium‐based energy storage devices are also outlined.

“…The oxide process is thorough, resulting in the transformation of superficial metal elements of 2D transition metal carbides into homologous transition metal oxides and the conversion of the carbon element of the MXene and some CO 2 to a gauzy unordered carbon film that serves as a "bond" to keep this framework complete. [183] One-step in situ growth methods include in situ oxidation growth method and in situ hydrolysis growth method. [170,181,182] In addition, to form Ti 3 C 2 T x /Na 0.23 TiO 2 composite, the Ti 3 C 2 T x is treated with sodium hydroxide for 120 h, for the purpose of oxidizing its surface to Na 0.23 TiO 2 .…”

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.
