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.

“…Under such a condition, the surface metal atoms were oxidized to orthorhombic Nb 2 O 5 or TiO 2 nanoparticles with sizes of dozens of nanometers, while unreacted Nb 4 C 3 T x or Ti 3 C 2 T x that was not converted to disordered graphitic carbon was left as the core, as revealed by the transmission electron microscopy (TEM) and high‐resolution TEM (HRTEM) images (Figure c). Besides, the partial oxidation of Ti 3 C 2 T x was also realized by direct hydration at a relatively low temperature for a long time (e.g., 200 °C for 24 h), thus constructing hierarchical accordion‐like TiO 2 @Ti 3 C 2 T x nanohybrids which showed an expanded interlayer spacing of ≈10.2 Å favorable for ion insertion and extraction (Figure b,d) . This strategy was straightforward in that it employed MXenes as the exclusive precursors.…”

Being conductive and flexible, MXenes, including transition metal carbides and nitrides, are expected to compete with, or even outperform graphene as 2D substrates serving in versatile applications. On the other hand, the extraordinary electrochemical activities of MXenes make them promising candidates as electrode materials in rechargeable batteries and supercapacitors, or as electrocatalysts in water splitting. However, MXenes are inclined to self‐restack due to hydrogen bonding or van der Waals interactions, which may lead to substantial loss of electroactive area as well as inaccessibility of ions and electrolytes. In this sense, hybridizing 2D MXenes and low‐dimensional inorganic nanostructures in elaborately designed architectures is of utmost significance, and provides a chance to integrate their unique properties in a complementary way. As such, this review is dedicated to highlighting recent progress in this regime, putting emphasis on the methods, structural and functional synergies, and energy‐related applications. Moreover, the present challenges and the future development directions are also discussed in depth.

Summary Compared with traditional anode materials, spinel‐structured Li4Ti5O12 (LTO) with “zero‐strain” characteristic offers better cycling stability. In this work, by a wet‐chemistry synthesis method, LTO anode materials have been successfully synthesized by using CH3COOLi·2H2O and C16H36O4Ti as raw materials. The results show that sintering conditions significantly affect purity, uniformity of particle sizes, and electrochemical properties of as‐prepared LTO materials. The optimized LTO product calcined at 650°C for 20 hours demonstrates small particle sizes and excellent electrochemical performances. It delivers an initial discharge capacity of 242.3 mAh g−1 and remains at 117.4 mAh g−1 over 500 cycles at the current density of 60 mA g−1 in the voltage range of 1.0 to 3.0 V. When current density is increased to 1200 mA g−1, its discharge capacity reaches 115.6 mAh g−1 at the first cycle and remains at 64.6 mAh g−1 after 2500 cycles. The excellent electrochemical performances of LTO can be attributed to the introduction of rutile TiO2 phase and small particle sizes, which increases electrical conductivity and electrode kinetics of LTO. Therefore, as‐synthesized LTO in this study can be regarded as a promising anode candidate material for lithium‐ion batteries.
