“…From the application point of view, the synthesis of a positively charged Ti 3 C 2 T x allows for its self‐assembly with the pristine MXene, which inherently possesses a negative surface charge . Figure 5B represents the pristine MXene, AEAPTMS‐Ti 3 C 2 T x , and the layer obtained from their assembly.…”

MXenes, two‐dimensional (2D) transition metal carbides and/or nitrides, possess surface termination groups such as hydroxyl, oxygen, and fluorine, which are available for surface functionalization. Their surface chemistry is critical in many applications. This article reports amine functionalization of Ti3C2Tx MXene surface with [3‐(2‐aminoethylamino)‐propyl]trimethoxysilane (AEAPTMS). Characterization techniques such as X‐ray photoelectron spectroscopy verify the success of the surface functionalization and confirm that the silane coupling agent bonds to Ti3C2Tx surface both physically and chemically. The functionalization changes the MXene surface charge from −35 to +25 mV at neutral pH, which allows for in situ preparation of self‐assembled films. Further, surface charge measurements of the functionalized MXene at different pH values show that the functionalized MXene has an isoelectric point at a pH around 10.7, and the highest reported positive surface charge of +62 mV at a pH of 2.58. Furthermore, the existence of a mixture of different orientations of AEAPTMS and the simultaneous presence of protonated and free amine groups on the surface of Ti3C2Tx are demonstrated. The availability of free amine groups on the surface potentially permits the fabrication of crosslinked electrically conductive MXene/epoxy composites, dye adsorbents, high‐performance membranes, and drug carriers. Surface modifications of this type are applicable to many other MXenes.

“…For example, the most widely studied member—titanium carbide MXene (Ti 3 C 2 T x )—has exhibited an electronic conductivity up to ~10 000 S/cm and an impressively high Young's modulus (0.33 ± 0.03 TPa) measured in the single layer, a value that is very close to the Young's modulus of micro‐mechanically exfoliated graphene (~1 TPa) . Because of this, MXenes have found extensive applications with impressive performance in supercapacitors (SCs), rechargeable (Li, Na, K‐ion) batteries, transparent conductive films, electromagnetic interference shielding, antibacterial coatings, water treatment, photothermal conversion, hydrogen storage, etc.…”

A family of 2D transition metal carbides and nitrides known as MXenes has received increasing attention since the discovery of Ti3C2 in 2011. To date, about 30 different MXenes with well‐defined structures and properties have been synthesized, and many more are theoretically predicted to exist. Due to the numerous assets including excellent mechanical properties, metallic conductivity, unique in‐plane anisotropic structure, tunable band gap, and so on, MXenes rapidly positioned themselves at the forefront of the 2D materials world and have found numerous promising applications. Particular interest is devoted to applications in electrochemical energy storage, whereby 2D MXenes work either as electrodes, additives, separators, or hosts. This review summarizes recent advances in the synthesis, fundamental properties and composites of MXene and highlights the state‐of‐the‐art electrochemical performance of MXene‐based electrodes/devices. The progresses in the field of supercapacitors and Li‐ion batteries, Li‐S batteries, Na‐ and other alkali metal ion batteries are reviewed, and current challenges and new opportunities for MXenes in this surging energy storage field are presented. In the focus of interest is the possibility to boost device‐level performance, particularly that of rechargeable batteries, which are of utmost importance in future energy technologies. Very recently, the 2019 Nobel Prize in Chemistry was awarded to the inventors of the Li‐ion battery. For sure, this will provide an additional stimulation to study fundamental aspects of electrochemical energy storage.

“…However, the field of energy storage research is moving exceptionally quickly, and because of this there has developed a degree of confusion within the scientific community about the criteria which determine whether a device is either a battery or a supercapacitor . Most reviews of MXenes in energy storage have sidestepped this blurred distinction by reviewing both technologies, but while these reviews are useful to those wishing to gain a broader perspective, they provide insufficient detail for readers who wish to understand the current state of research into either batteries or supercapacitors specifically. Therefore, the present review shall focus on works which self‐identify as battery research, and discuss progress with the assumption that these MXene‐based electrodes could take the place of graphite in a set‐up not dissimilar from a conventional Li‐ion battery (Figure ).…”

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.
