“…These energies are a confirmation of the 2H‐MoTe 2 phase, according to the existing literature. [ 25,28–30 ] There are two additional XPS peaks at 232.16 (Mo 3d 5/2 ) eV and 235.33 eV (Mo 3d 3/2 ), which are due to the molybdenum oxide (MoO 3 ) phase that results from the formation of oxide on the surface of the sample that is under air exposure, and the same feature is observed in the earlier literature. [ 28,30 ] Figure 1e shows that the Te 3d HR‐XPS spectra at 572.87 (Te 3d 5/2 ) and 583.26 eV (Te 3d 3/2 ) are the 2H‐MoTe 2 characteristic peaks.…”

“…[ 25,27,28,40 ] There are a number of possible reasons for this discrepancy. The most likely reasons are the pseudocapacitive behavior of TMDs at lower potentials, [ 25,27,32,41 ] and the job‐sharing mechanism between Mo‐nanoparticles and Li during conversion reaction. [ 27,31 ] The formation of the gel‐like polymer film (shown in Figure S4b, Supporting Information, for the electrode after full discharge) due to a high surface area and more active sites causes the decomposition of electrolytes during the electrochemical reaction.…”

“…The continuous decrease of the R ct with cycling proves that faster Li + mobility in the MoTe 2 electrode leads to low overpotential after the first cycle. [ 25 ] Further, the Li + diffusion coefficient (D Li+ ) is calculated from the in situ ElS, which is performed at different discharging and charging potentials of the second cycle, as shown in Figure S7a,b, Supporting Information. The inclined line at the low‐frequency region (Figure S7a,b, Supporting Information) implies the Warburg behavior, which is associated with lithium‐ion diffusion within the MoTe 2 electrode.…”

The major challenges faced by candidate electrode materials in lithium‐ion batteries (LIBs) include their low electronic and ionic conductivities. 2D van der Waals materials with good electronic conductivity and weak interlayer interaction have been intensively studied in the electrochemical processes involving ion migrations. In particular, molybdenum ditelluride (MoTe2) has emerged as a new material for energy storage applications. Though 2H‐MoTe2 with hexagonal semiconducting phase is expected to facilitate more efficient ion insertion/deinsertion than the monoclinic semi‐metallic phase, its application as an anode in LIB has been elusive. Here, 2H‐MoTe2, prepared by a solid‐state synthesis route, has been employed as an efficient anode with remarkable Li+ storage capacity. The as‐prepared 2H‐MoTe2 electrodes exhibit an initial specific capacity of 432 mAh g−1 and retain a high reversible specific capacity of 291 mAh g−1 after 260 cycles at 1.0 A g−1. Further, a full‐cell prototype is demonstrated by using 2H‐MoTe2 anode with lithium cobalt oxide cathode, showing a high energy density of 454 Wh kg−1 (based on the MoTe2 mass) and capacity retention of 80% over 100 cycles. Synchrotron‐based in situ X‐ray absorption near‐edge structures have revealed the unique lithium reaction pathway and storage mechanism, which is supported by density functional theory based calculations.

“…For example, MoSe 2 is a structural analogue of MoS 2 ; however, it has a narrower bandgap and greater interlayer spacing with respect to MoS 2 , indicative of its superior performance as an anode in SIB systems . Likewise, MoTe 2 , another important member of the TMD family, also exhibits large interlayer spacing (0.70 nm) to be able to accommodate larger ions (e.g., the 0.35 nm Na + ion for SIB systems) . Te also demonstrates greater electronic conductivity (2×10 2 S m −1 ) than both S (5×10 −13 S m −1 ) and Se (1×10 −3 S m −1 ); thereby indicating improved electronic conductivity .…”

Atomically thin sheets of two‐dimensional (2D) transition metal dichalcogenides (TMDs) have attracted interest as high capacity electrode materials for electrochemical energy storage devices owing to their unique properties (high surface area, high strength and modulus, faster ion diffusion, and so on), which arise from their layered morphology and diversified chemistry. Nevertheless, low electronic conductivity, poor cycling stability, large structural changes during metal‐ion insertion/extraction along with high cost of manufacture are challenges that require further research in order for TMDs to find use in commercial batteries and supercapacitors. Here, a systematic review of cutting‐edge research focused on TMD materials beyond the widely studied molybdenum disulfide or MoS2 electrode is reported. Accordingly, a critical overview of the recent progress concerning synthesis methods, physicochemical and electrochemical properties is given. Trends and opportunities that may contribute to state‐of‐the‐art research are also discussed.

Second, the recent progress on abundant physical properties of 2D MTACs is briefly introduced, including surface electronic properties, optoelectronic properties, electronic transport, and thermoelectric properties, ferroelectric properties, superconducting properties, and ferromagnetic properties. Third, the potential electronics, spintronics, optoelectronics and energy applications of 2D MTACs are presented. Finally, some significant challenges and opportunities in 2D MTACs are briefly addressed.
