“…Figure S3 in the Supporting Information shows the capacitance contributions of the four electrodes as 17, 27, 7, and 14 % for MXene, FMX3, FMX6, and FMX24, respectively. MXene shows two reversible peaks with anodic/cathodic peak values of approximately 0.9/0.8 and 2.4/2.2 V, which is similar to other reported Ti 3 C 2 materials . The FMX3 profile shows more peaks, which is the result of the presence of electrochemically active TiF 3, as observed from the XPS results (see Figure b).…”

What prompted you to investigate this topic/problem? Lithium-ion batteries (LIBs), due to the inherentl imitations of traditional electrode materials, have relatively low energy and power density which hinders their application for electric vehicles. In order to tackle this problem, different engineering routes are being developed to increase their performance. Therefore, we have developed ad irect-fluorination process for the formation of oxyfluorides with the aim of also improving the cost effectiveness and practicality.D irect fluorination by elemental fluorine is one of the best solutions to obtain highly pure oxyfluoride materials, whicho ur group is using for research on electrode materials. With this approach, we have demonstrated for the first time the formation of 2D-titanium oxyfluoride (TiOF 2 )v ia low temperature directfluorination.

Ti C T , a typical representative among the emerging family of 2D layered transition metal carbides and/or nitrides referred to as MXenes, has exhibited multiple advantages including metallic conductivity, a plastic layer structure, small band gaps, and the hydrophilic nature of its functionalized surface. As a result, this 2D material is intensively investigated for application in the energy storage field. The composition, morphology and texture, surface chemistry, and structural configuration of Ti C T directly influence its electrochemical performance, e.g., the use of a well-designed 2D Ti C T as a rechargeable battery anode has significantly enhanced battery performance by providing more chemically active interfaces, shortened ion-diffusion lengths, and improved in-plane carrier/charge-transport kinetics. Some recent progresses of Ti C T MXene are achieved in energy storage. This Review summarizes recent advances in the synthesis and electrochemical energy storage applications of Ti C T MXene including supercapacitors, lithium-ion batteries, sodium-ion batteries, and lithium-sulfur batteries. The current opportunities and future challenges of Ti C T MXene are addressed for energy-storage devices. This Review seeks to provide a rational and in-depth understanding of the relation between the electrochemical performance and the nanostructural/chemical composition of Ti C T , which will promote the further development of 2D MXenes in energy-storage applications.

“…Commercial graphite anodes suffer from relatively low theoretical capacity (≈372 mAh g −1 ) and sluggish ion kinetics (10 −11 –10 −10 cm 2 s −1 ) upon Li + intercalation/de‐intercalation . Engineering the electrode by nanostructuring or designing porous low‐dimensional materials may result in faster Li + diffusion and thus improve their rate capability . Recently, 2D nanomaterials have attracted huge research attention for their use in LiBs due to their exotic properties .…”

2D metal chalcogenide (MC) nanosheets (NS) have displayed high capacities as lithium‐ion battery (LiB) anodes. Nevertheless, their complicated synthesis routes coupled with low electronic conductivity greatly limit them as promising LiB electrode material. Here, this work reports a facile single‐walled carbon nanotube (SWCNT) percolating strategy for efficiently maximizing the electrochemical performances of gallium chalcogenide (GaX, X = S or Se). Multiscaled flexible GaX NS/SWCNT heterostructures with abundant voids for Li+ diffusion are fabricated by embedding the liquid‐exfoliated GaX NS matrix within a SWCNT‐percolated network; the latter improves the electron transport and ion diffusion kinetics as well as maintains the mechanical flexibility. Consequently, high capacities (i.e., 838 mAh g−1 per gallium (II) sulfide (GaS) NS/SWCNT mass and 1107 mAh g−1 per GaS mass; the latter is close to the theoretical value) and good rate capabilities are achieved, which can be majorly attributed to the alloying processes of disordered Ga formed after the first irreversible GaX conversion reaction, as monitored by in situ X‐ray diffraction. The presented approach, colloidal solution processing of SWCNT and liquid‐exfoliated MC NS to produce flexible paper‐based electrode, could be generalized for wearable energy storage devices with promising performances.
