“…Under the regulation of MXene framework, the electrochemical performance of these SnO 2 / MXene composites was obviously improved. [120,121] To improve the electrochemical performance of VO 2 anode for SIBs, Wu and co-workers designed a 3D flower-like VO 2 /MXene composite by hydrothermal method (Figure 12b).

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.

Tin oxide (SnO2) is a useful anode material due to its high capacity (1493 mAh g−1 and 1378 mAh g−1 vs Li/Li+ and vs Na/Na+, respectively) and natural abundance (tin is one of the thirty most abundant elements on Earth). Unfortunately, only moderate electrical conductivity and significant volume expansion of up to 300% for Li-ion, and as much as 520% for Na-ion can occur. Here, we use an ordered macroporous interconnected inverse opal (IO) architectures to enhance rate capability, structural integrity, and gravimetric capacity, without conductive additives and binders. Excellent capacity retention is shown during cycling vs Na/Na+ relative to Li/Li+. Cyclic voltammetry (CV) analysis, galvanostatic cycling, and differential capacity analysis extracted from rate performance testing evidence the irreversibility of the oxidation of metallic Sn to SnO2 during charge. This behavior allows for a very stable electrode during cycling at various rates. A stable voltage profile and rate performance is demonstrated for both systems. In a Na-ion half cell, the SnO2 retained >76% capacity after 100 cycles, and a similar retention after rate testing.

“…26 Chen et al fabricated nanoparticles of SnO 2 on MXene and reported a specific capacity of 414.3 mA h/g. 27 Although SnO 2 composites with MXene considerably improved electrical conductivity, 28 specific capacity, 29 and stable cyclic capacity 30 of charge storage devices, there are still outstanding challenges to be considered for further improvements. For instance, the interfacial interactions between the surface functional groups of MXene and metal oxide heterostructures (HSs) make them unstable for long-lasting applications.…”

Investigation of Electrical and Electrochemical Properties of Ascorbic Acid-Treated SnO₂/MXene Heterostructures for Hybrid Supercapacitors

Recently, Ti 3 C 2 T x (MXene) and its heterostructures (HSs) with metal oxides have emerged as excellent materials for supercapacitors considering its distinctive electrochemical properties. However, environmental instability and poor interfacial interactions in two-dimensional (2D) Ti 3 C 2 T x (MXene) and its HSs with metal oxides (due to surface group repulsion) have been a great challenge. Moreover, restacking of MXene passivates the active sites of the electrode. Here, we presented a novel approach to synthesizing ascorbic acid-treated MXene/SnO 2 HS-based flexible electrodes for SCs. Assynthesized 3D SnO 2 nanoflowers (NFs) were treated with ascorbic acid to activate their surface and provide a linkage site for MXene sheets. SnO 2 NFs not only act as nanopillars between these layers but also maintain an appropriate space between the 2D layers and provide a 2D surface for charge storage. In conclusion, the self-assembly of these 2D−3D structures is retained, making it a more promising material for high-performance SC electrodes. The reported material not only presented an appreciable specific capacitance of 643 F/g but also demonstrated great electrochemical stability (only a 2% decrease) after 1000 cycles. In addition, the SnO 2 -anchored MXene showed great resistance against environmental humidity.
