“…Another example of a 1D MoS 2 material is the typical hierachical hollow MoS 2 nanotubes that are produced by a solvothermal reaction of Na 2 MoO 4 ·2H 2 O, MnCl 2 ·4H 2 O, and (NH 4 ) 2 CS, followed by etching the MnCO 3 nanotubes.

“…To overcome these shortcomings, a large amount of efforts was devoted to modify the electrochemical performance of 2H‐MoS 2 . Two general ways are: 1) designing nanostructure materials, such as nanotubes, nanosheets, and nanospheres; 2) hybridizing 2H‐MoS 2 with carbonaceous materials, such as graphene . Compared with 2H phase MoS 2 , 1T phase MoS 2 presents a metallic transport behavior and its electric conductivity is approximately 5 orders of magnitudes higher than that in semiconducting 2H‐MoS 2 .…”

commercial LIBs with graphite-based materials as anode cannot meet the above requirements due to the limitation of graphite itself. It shows a low theoretical capacity of 372 mAh g −1 , [2] rapid capacity decay, and possible safety issues during cycling process. Recently, transition metal dichalcogenides (TMDs) have attracted widespread attention in the energy storage fields, especially its application in electrodes of LIBs. As a representative of TMDs, MoS 2 has shown fascinating and superior electrochemical performance due to its unique layered structure. [3,4] MoS 2 always exists in the following three phases: 2H, 1T, and 3R phase according to different coordinations of Mo and S atoms. [5][6][7][8][9] The 2H and 1T phase MoS 2 exhibit notable energy storage and conversion performance due to their characteristic structure and rich physical and chemical properties. 2H-MoS 2 is a semiconducting phase with trigonal prismatic structure. Its high theoretical capacity of 670 mAh g −1 renders it fit to be considered as a promising anode material for LIBs. [10,11] However, two severe issues of 2H-MoS 2 electrode still need to be taken into account: 1) the structure destruction induced by the large volume change during lithium-ions intercalating and deintercalating process; 2) the poor electronic conductivity, arising from a large bandgap of about 1.9 eV. [12,13] To overcome these shortcomings, a large amount of efforts was devoted to modify the electrochemical performance of 2H-MoS 2 . Two general ways are: 1) designing nanostructure materials, such as nanotubes, [14] nanosheets, [15] and nanospheres [16] ; 2) hybridizing 2H-MoS 2 with carbonaceous materials, such as graphene. [17,18] Compared with 2H phase MoS 2 , 1T phase MoS 2 presents a metallic transport behavior and its electric conductivity is approximately 5 orders of magnitudes higher than that in semiconducting 2H-MoS 2 . [19] This contributes to the transfer of electrons and ions in the electrode material. Furthermore, 1T-MoS 2 owns an expanded interlayer spacing of about 1 nm, which is nearly 1.5 times larger than that in 2H-MoS 2 (about 0.65 nm). [20,21] Such an expanded interlayer spacing makes lithium ions embedding and de-embedding much easier. However, the conventional methods to fabricate 1T-MoS 2 require an alkali metal intercalation or exfoliation process, which is unstable, dangerous, complicated, and time-consuming. [22] Preparing 1T phase MoS 2 possesses higher conductivity than the 2H phase, which is a key parameter of electrochemical performance for lithium ion batteries (LIBs). Herein, a 1T-MoS 2 /C hybrid is successfully synthesized through facile hydrothermal method with a proper glucose additive. The synthesized hybrid material is composed of smaller and fewer-layer 1T-MoS 2 nanosheets covered by thin carbon layers with an enlarged interlayer spacing of 0.94 nm. When it is used as an anode material for LIBs, the enlarged interlayer spacing facilitates rapid intercalating and deintercalating of lithium ions and accommodates volume change dur...

“…One of the most promisinga pproaches towards achieving this goal is to develop next-generation lithium-ion batteries (LIBs) to replace conventional LIBs containing LiCoO 2 and graphite.O nt he other hand, sodium-ion batteries (SIBs) are regarded as another promising candidate due to the abundant sodium sourcesi n the Earth's crust. Transition metal dichalcogenides, including WS 2 [1][2][3][4][5] and MoS 2 , [6][7][8][9][10] have been extensively studied as anode materials for both LIBs and SIBs. These materials crystallize in al ayered structure, in which the W( or Mo) and Sa toms are tightly bonded by covalent forces to form slabs, and the adjacent slabs are bonded by weak van der Waals forces.…”

An integrated WS @CMK-3 nanocomposite has been prepared by a one-step hydrothermal method and then used as the anode material for lithium-ion and sodium-ion batteries. Ultrathin WS nanosheets have been successfully embedded into the ordered mesoporous carbon (CMK-3) framework. Owing to the few-layered nanostructure of WS , as well as the high electronic conductivity and the volume confinement effect of CMK-3, the material shows larger discharge capacity, better rate capability, and improved cycle stability than pristine WS . When tested in lithium-ion batteries, the material delivers a reversible capacity of 720 mA h g after 100 cycles at a current density of 100 mA g . A large discharge capacity of 307 mA h g is obtained at a current density of 2 A g . When used in sodium-ion batteries, the material exhibits a capacity of 333 mA h g at 100 mA g without capacity fading after 70 cycles. A discharge capacity of 230 mA h g is obtained at 2 A g . This excellent performance demonstrates that the WS @CMK-3 nanocomposite has great potential as a high-performance anode material for next-generation rechargeable batteries.
