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.

“…Their combination of metallic conductivity, high density (3.8 ± 0.3 g cm −3 ), and redox active, negatively charged surfaces can lead to superior charge storage and transfer capabilities when compared to other 2D materials. Their surface functional groups (O, OH, and F) further render them hydrophilic allowing them to be easily dispersed into aqueous suspensions and inks for processing electrodes using different approaches such as vacuum filtration, spin coating, screen printing, stamping, and spraying . While these approaches show the potential of MXene for water‐based processing of EES devices, limitations remain with respect to architectural control, scalability, or cost‐effectiveness that could be addressed by employing 3D printing technologies.…”

formulations that can maximize surface area accessibility and ion transport within electrodes while minimizing space and environmental impact. Consequently, Additive Manufacturing (AM) technologies, which are capable of printing 3D objects and complex structures, offer unique possibilities to bring novel electrode materials into highperformance EES devices. Among the AM technologies, continuous extrusion-based 3D printing (also called direct ink writing or robocasting) is a versatile and costeffective processing route where the formulation and properties of colloidal inks directly control the printability and architecture of printed parts. It further offers the ability to integrate functional materials of different surface chemistry and dimensionality into EES devices [1] such as Li-ion batteries, [2][3][4] micro-supercapacitors (MSCs), [5,6] and wearable electronics. [7,8] Recently, 2D transition metal carbides, called MXenes (M n+1 X n T x , with M representing an early transition metal, X representing C and/or N and, and T x representing the terminal functional groups), [9,10] have shown huge potential as electrode materials for supercapacitors. [11,12] Their combination of metallic conductivity, high density (3.8 ± 0.3 g cm −3 ), and redox active, negatively charged surfaces can lead to superior charge storage and transfer capabilities when compared to other 2D materials. Their surface functional groups (O, OH, and F) further render them hydrophilic allowing them to be easily dispersed into aqueous suspensions and inks for processing electrodes using different approaches such as vacuum filtration, [10,13] spin coating, [14,15] screen printing, [16,17] stamping, [18] and spraying. [19][20][21] While these approaches show the potential of MXene for water-based processing of EES devices, limitations remain with respect to architectural control, scalability, or cost-effectiveness that could be addressed by employing 3D printing technologies. Although MXene aqueous inks have been recently employed in commercial pens for direct writing functional films, [22] the development of 3D printable MXene inks and their integration into customized 3D device architectures is still unexplored. In order to realize this challenge, these materials need to be integrated into inks with very specific rheological properties that allow smooth flow through narrow nozzles while still enabling the extruded filaments to retain their shape even after multiple layers are Additive manufacturing (AM) technologies appear as a paradigm for scalable manufacture of electrochemical energy storage (EES) devices, where complex 3D architectures are typically required but are hard to achieve using conventional techniques. The combination of these technologies and innovative material formulations that maximize surface area accessibility and ion transport within electrodes while minimizing space are of growing interest. Herein, aqueous inks composed of atomically thin (1-3 nm) 2D Ti 3 C 2 T x with large lateral size of about 8 µm possessing ideal vis...

“…To date, MXenes have been used in numerous applications, achieving, in many cases, record values. MXenes have been used as electrodes in batteries and electrochemical capacitors, textile supercapacitors, photodetectors, electrical contacts such as Schottky electrodes, or ohmic contacts with modified MXene chemistries, and spayed‐on antennas . Since transparent contacts are widely used for touch sensitive screens, solar cells, and organic light emitting diodes (OLED), MXenes could also be materials of choice for these applications.…”

The need for high-speed, highresponsivity detection is traditionally met by p-type-intrinsic-n-type (PIN) photodiodes, [1] avalanche photodiodes (APD), [2] metal-semiconductor-metal (MSM), [3,4] or metal-graphene-metal [5][6][7] photodetectors.Of these, top-illuminated, MSM devices are planar, relatively easy to fabricate, and are more readily integratable with field effect transistor (FET) technology as they exploit the same Schottky contacts used for the FET gate, and do not require the
