  Assembling two-dimensional (2D) materials into functional three-dimensional (3D) structures can enable their use in a wide variety of applications. For energy storage devices, 3D electrodes with high ionic and electronic transport properties and decent mechanical properties are expected to prompt the fabrication of the next generations of devices with high energy and power densities. Herein, we report a simple, efficient, and scalable process based on unidirectional freeze casting to fabricate ordered and porous 3D aerogels from 2D Ti3C2Tx MXene flakes. The fabricated aerogels show excellent mechanical, electrical, and electrochemical properties. Our studies show that the processing conditions significantly affect the properties of MXene aerogels. The electrical conductivity and mechanical properties of fabricated aerogels directly correlate with their structural features. The mechanical test results showed that MXene aerogels with ordered structures could withstand almost 50% of strain before recovering to their original shape and maintain their electrical conductivities during continuous compressive cycling. As electrode materials for lithium-ion capacitors, the fabricated aerogels delivered a significantly high specific capacity (~1210 mAh/g at 0.05 A/g), excellent rate capability (~200 mAh/g at 10 A/g), and outstanding cycling performance. We believe that the MXene aerogels with ordered structures have promising properties for a broad range of applications, including energy storage devices and strain sensors.

  3D Printed MXene Aerogels with Truly 3D Macrostructure and Highly Engineered Microstructure for Enhanced Electrical and Electrochemical Performance

  . Advanced Materials. doi:10.1002/adma.202104980
  More info

  Assembling 2D materials such as MXenes into functional 3D aerogels using 3D printing technologies gains attention due to simplicity of fabrication, customized geometry and physical properties, and improved performance. Also, the establishment of straightforward electrode fabrication methods with the aim to hinder the restack and/or aggregation of electrode materials, which limits the performance of the electrode, is of great significant. In this study, unidirectional freeze casting and inkjet-based 3D printing are combined to fabricate macroscopic porous aerogels with vertically aligned Ti3 C2 Tx sheets. The fabrication method is developed to easily control the aerogel microstructure and alignment of the MXene sheets. The aerogels show excellent electromechanical performance so that they can withstand almost 50% compression before recovering to the original shape and maintain their electrical conductivities during continuous compression cycles. To enhance the electrochemical performance, an inkjet-printed MXene current collector layer is added with horizontally aligned MXene sheets. This combines the superior electrical conductivity of the current collector layer with the improved ionic diffusion provided by the porous electrode. The cells fabricated with horizontal MXene sheets alignment as current collector with subsequent vertical MXene sheets alignment layers show the best electrochemical performance with thickness-independent capacitive behavior.

  A Review of the Effects of Electrode Fabrication and Assembly Processes on the Structure and Electrochemical Performance of 2D MXenes

  . Advanced Functional Materials. doi:10.1002/adfm.202005305
  More info

  Abstract MXenes are 2D materials with relatively high surface areas, high electrical conductivities, functional transition metal surfaces, tunable surface chemistries, and solution processability. Due to these properties, 2D MXenes have attracted widespread attention as electrode materials for energy storage devices, including electrochemical capacitors, with high power and energy densities. However, many studies have shown that the electrochemical performance of MXene electrodes is considerably affected by their structure and morphology. These properties are, for the most part, controlled by the method used for the assembly of 2D MXene flakes and the electrode fabrication methods. A successful electrode assembly and fabrication method should address several challenges, such as the restacking of 2D flakes, to achieve electrode structures and morphologies that deliver high ionic transport properties, electrical conductivity, and mechanical stability. This review aims to provide insight into the current state‐of‐the‐art assembly and fabrication methods used to design and fabricate high performance electrodes based on MXenes. The major challenges to be addressed and possible future directions in the fabrication of MXene electrodes for practical energy storage applications are highlighted.

  Controlling the Dimensions of 2D MXenes for Ultrahigh-Rate Pseudocapacitive Energy Storage

  . ACS applied materials & interfaces. doi:10.1021/acsami.8b07397
  More info

  The capacitive properties of two-dimensional (2D) transition metal carbides/nitrides (MXenes) have been the focus of much research in recent years. MXenes store charge by the pseudocapacitance mechanism (fast surface redox reactions) but can deliver their stored charge at much higher rates compared to other pseudocapacitive materials. Herein, the dependence of the electrochemical properties of MXenes on their lateral dimensions is reported. We show that synthesizing MXenes with controlled dimensions enables the design and fabrication of electrodes with high electronic and ionic conductivities. At low scan rates, electrodes fabricated using a mixture of small and large flakes could deliver very high specific gravimetric and volumetric capacitances of about 435 F g–1 and 1513 F cm–3, respectively. At a very high scan rate of 10 V s–1, the performance of the electrodes remained capacitive, demonstrating their ultrahigh-rate energy storage capability. This work outlines an effective method for the design and fabrication of MXene electrodes with high energy and power densities.

  Assembling 2D MXenes into Highly Stable Pseudocapacitive Electrodes with High Power and Energy Densities

  . Advanced Materials. doi:10.1002/adma.201806931
  More info

  Abstract Electrochemical capacitors (ECs) that store charge based on the pseudocapacitive mechanism combine high energy densities with high power densities and rate capabilities. 2D transition metal carbides (MXenes) have been recently introduced as high‐rate pseudocapacitive materials with ultrahigh areal and volumetric capacitances. So far, 20 different MXene compositions have been synthesized and many more are theoretically predicted. However, since most MXenes are chemically unstable in their 2D forms, to date only one MXene composition, Ti 3 C 2 T x , has shown stable pseudocapacitive charge storage. Here, a cation‐driven assembly process is demonstrated to fabricate highly stable and flexible multilayered films of V 2 CT x and Ti 2 CT x MXenes from their chemically unstable delaminated single‐layer flakes. The electrochemical performance of electrodes fabricated using assembled V 2 CT x flakes surpasses Ti 3 C 2 T x in various aqueous electrolytes. These electrodes show specific capacitances as high as 1315 F cm −3 and retain ≈77% of their initial capacitance after one million charge/discharge cycles, an unprecedented performance for pseudocapacitive materials. This work opens a new venue for future development of high‐performance supercapacitor electrodes using a variety of 2D materials as building blocks.

  Controlling the actuation properties of MXene paper electrodes upon cation intercalation

  . Nano Energy. doi:10.1016/j.nanoen.2015.07.028
  More info

  Atomic force microscopy was used to monitor the macroscopic deformation in a delaminated Ti3C2 paper electrode in situ, during charge/discharge in a variety of aqueous electrolytes to examine the effect of the cation intercalation on the electrochemical behavior and mechanical response. The results show a strong dependence of the electrode deformation on cation size and charge. The electrode undergoes a large contraction during Li+, Na+ or Mg2+ intercalation, differentiating the Ti3C2 paper from conventional electrodes where redox intercalation of ions (e.g. Li+) into the bulk phase (e.g. graphite, silicon) results in volumetric expansion. This feature may explain the excellent rate performance and cyclability reported for MXenes. We also demonstrated that the variation of the electromechanical contraction can be easily adjusted by electrolyte exchange, and shows interesting characteristics for the design of actuators based on 2D metal carbides.

  Capacitive energy storage in micro-scale devices: recent advances in design and fabrication of micro-supercapacitors

  . Energy and Environmental Science. doi:10.1039/c3ee43526a
  More info

  Miniaturized energy storage is essential for the continuous development and further miniaturization of electronic devices. Electrochemical capacitors (ECs), also called supercapacitors, are energy storage devices with a high power density, fast charge and discharge rates, and long service life. Small-scale supercapacitors, or micro-supercapacitors, can be integrated with microelectronic devices to work as stand-alone power sources or as efficient energy storage units complementing batteries and energy harvesters, leading to wider use of these devices in many industries. In recent years, the research in this field has rapidly advanced and micro-supercapacitors with improved storage capacity and power density have been developed. The important factors affecting the performance of micro-supercapacitors are the intrinsic properties of electrode materials and electrolyte, architectural design of the device and the fabrication methods. This paper reviews the recent advances in fabrication of materials and devices and provides a critical analysis of reported performances of micro-supercapacitors.

  Activated Carbon Spheres as a Flowable Electrode in Electrochemical Flow Capacitors

  . Journal of The Electrochemical Society. doi:10.1149/2.072406jes
  More info

  Here, we report modified carbon spheres (CS) as a high energy and power density flowable electrode for use in electrochemical flow capacitors – a new energy storage concept proposed by our group. Activated CS with high specific surface area (SSA) of 1157 m2 g−1 were obtained by CO2 activation. The electrochemical performance of the flowable electrodes as tested in both aqueous (KOH) and organic (TEABF4/PC) electrolytes. It was observed that both the morphology and electrochemical performance of the flowable electrodes are strongly dependent on the activation conditions. Among tested samples, flowable electrode composed of CS activated at 1000°C for one hour yielded the highest capacitance, rate handling ability, and lowest equivalent series resistance (ESR) values. When tested in a static configuration, these suspension electrodes showed a specific capacitance of 139 Fg−1, which is comparable to the performance of traditional film electrodes. The performance of the CS-1000 was further investigated under intermittent flow condition using slurry containing 16 wt% of CS. It was observed that CS-1000 showed significantly enhanced performance due to its high surface area, decreased ohmic resistance, and enhanced conductivity, both in static and under intermittent flow conditions as compared to the flowable electrodes previously reported by our group.

  Composite Manganese Oxide Percolating Networks As a Suspension Electrode for an Asymmetric Flow Capacitor

  . ACS applied materials & interfaces. doi:10.1021/am501650q
  More info

  In this study, we examine the use of a percolating network of metal oxide (MnO2) as the active material in a suspension electrode as a way to increase the capacitance and energy density of an electrochemical flow capacitor. Amorphous manganese oxide was synthesized via a low-temperature hydrothermal approach and combined with carbon black to form composite flowable electrodes of different compositions. All suspension electrodes were tested in static configurations and consisted of an active solid material (MnO2 or activated carbon) immersed in aqueous neutral electrolyte (1 M Na2SO4). Increasing concentrations of carbon black led to better rate performance but at the cost of capacitance and viscosity. Furthermore, it was shown that an expanded voltage window of 1.6 V could be achieved when combining a composite MnO2-carbon black (cathode) and an activated carbon suspension (anode) in a charge balanced asymmetric device. The expansion of the voltage window led to a significant increase in the energy density to ∼11 Wh kg–1 at a power density of ∼50 W kg–1. These values are ∼3.5 times and ∼2 times better than a symmetric suspension electrode based on activated carbon.
