MXene is an emerging 2D material and shows large potential as a substrate for in situ growth of functional materials due to its merits such as large surface area, abundant nucleation sites, structural diversity, superior dispersion ability, blocking agglomeration of nanomaterials, and rich element/kind compositions. The in situ‐formed MXene‐based composites are largely applied in rechargeable batteries in the past several years by acting as active materials, serving as current collectors, decorating separators, and catalyzing electrochemical process. However, a detailed and systematic summary is still lacked. Herein, a review on in situ growth engineering on 2D MXene for next‐generation rechargeable batteries is presented in detail for the first time. Meanwhile, some outlooks and perspectives are put forward. In situ growth engineering on 2D MXenes can be achieved by calcination method, hydrothermal method, solvothermal method, room‐temperature liquid‐phase reduction method, room‐temperature liquid‐phase oxidation method, electrochemical deposition method, in situ polymerization method, vapor deposition method, mechanical milling method, microwave method, composite method, self‐reduction method, coprecipitation method, immersion method, hydrolysis method, etc. These in situ growth strategies can be extended to materials beyond MXenes, such as graphene, MBene, graphdiyne, etc.

“…The etching was done following the synthetic method used in previous work. [55,75] The etching was performed using the following route: 500 mg of Ti 3 AlC 2 (size <50 µm) was kept under stirring in a Teflon beaker containing an aqueous solution of hydrofluoric acid (HF) 30 mass% for 5 h at room temperature. The powder was recovered and washed by a series of centrifugation steps until the pH of the washing liquid was ≈6.…”

Lithium‐ion batteries are constantly developing as the demands for power and energy storage increase. One promising approach to designing high‐performance lithium‐ion batteries is using conversion/alloying materials, such as SnO2. This class of materials does, in fact, present excellent performance and ease of preparation; however, it suffers from mechanical instabilities during cycling that impair its use. One way to overcome these problems is to prepare composites with bi‐dimensional materials that stabilize them. Thus, over the past 10 years, two‐dimensional materials with excellent transport properties (graphene, MXenes) have been developed that can be used synergistically with conversion materials to exploit both advantages. In this work, a 50/50 (by mass) SnO2/Ti3C2Tz nanocomposite is prepared and optimized as a negative electrode for lithium‐ion batteries. The nanocomposite delivers over 500 mAh g−1 for 700 cycles at 0.1 A g−1 and demonstrates excellent rate capability, with 340 mAh g−1 at 8 A g−1. These results are due to the synergistic behavior of the two components of the nanocomposite, as demonstrated by ex situ chemical, structural, and morphological analyses. This knowledge allows, for the first time, to formulate a reaction mechanism with lithium‐ions that provides partial reversibility of the conversion reaction with the formation of SnO.

“…[15,16] The high-surface delaminated MXene sheets have be used in gas storage, [17] as photo- [18] or electro-catalyst, [19,20] in water desalination, [21,22] and in electrochemical capacitors and rechargeable batteries. [5,23,24] Specifically, the optimal interlayer distance and other beneficial properties of the MXene such as high electrical conductivity, good mechanical properties, and flexibility, make this class of compounds extremely suitable for this latter application. Furthermore, the dipolar interactions between these T x groups do not allow the flaking or pulverization of the particles during the intercalation and deintercalation processes of the ions.…”

MXenes are an emerging class of materials considered for many applications, such as sensors, catalysis, energy storage devices. The main obstacle towards their massive implementation is the synthesis requiring the direct use of HF as etching agent. The development of alternative synthetic routes exploiting in-situ forming HF agents is the main strategies to overcome this limitation. In this study four different etching methods based on the use of NH 4 HF 2 , NaFÀ HCl, HBF 4 , and NaBF 4 À HCl are compared to produce Ti 3 C 2 T x from Ti 3 AlC 2 towards the application of MXenes in sodium ion batteries. Three of such etching methods have already been reported while one is here presented for the first time. The structural analysis of the obtained products is based on X-ray diffraction (XRD), scanning electron microscopy-energy dispersive X-ray spectroscopy (SEM-EDX), and X-ray photoelectron spectroscopy (XPS) analysis. All the materials have been tested in half-cell configuration vs. Na; the charge/discharge profiles and the C-rate tests are discussed and related to specific structural features. Overall, the results reveal that the MXene obtained using the HBF 4 etching agent under mild conditions is comparable both in structure and functional properties to the benchmark material, i. e., the MXene produced using HF at 5 % concentration. Indeed, the MXene synthetized with the HBF 4 presents the lowest mean voltage and potential hysteresis and shows the highest first cycle efficiency (69.7 %), overcoming the performance of the MXene produced with 5 % HF (67 %). This study proves the possibility to produce MXene with a more sustainable route.
