Hierarchical nanotubes assembled from MoS 2 -carbon monolayer sandwiched superstructure nanosheets for high-performance sodium ion batteries

Interlayer Nanoarchitectonics of Two‐Dimensional Transition‐Metal Dichalcogenides Nanosheets for Energy Storage and Conversion Applications

“…In such superstructures, the interlayer spacings of MX 2 can be significantly enlarged by carbon layer intercalation, which is beneficial for fast reaction kinetics. Such sandwiched MoX 2 :C superstructures have been a hotspot for applications as high-performance electrodes in LIBs, [70,76,81,102,[106][107][108]119] SIBs [111,114] and MIBs. [120,121] The approaches for synthesizing sandwiched MX 2 :C superstructure typically include (i) exfoliation/restacking method by incorporating graphenes or organic molecules that can be easily carbonized upon annealing, [70,121] (ii) hydrothermal/ solvothermal methods with addition of pre-synthesized graphenes and carbon quantum dots that can be intercalated into MX 2 , [102,106,119] and (iii) hydrothermal/solvothermal methods that contain organic molecules, such as glucose, PVP, octylamine, oleic acid, dopamine, CTAB, that can be intercalated and carbonized.…”

Emerging nanostructured electrode materials for water electrolysis and rechargeable beyond Li-ion batteries

“…The most studied TMDC phases in energy storage application include MoS 2 [108][109][110][111][112][113][114][115][116][117][118][119][120][121][122][123][124][125], MoSe 2 [126][127][128][129][130][131], WS 2 [132][133][134][135], and WSe 2 [136][137][138]. MoS 2 , with the interlayer distance of 6.2 Å, is explored as an anode material for SIBs.…”

“…Many examples of the hybrid TMDC@carbon structures demonstrating enhanced electrochemical properties have been reported [115][116][117][118][119][120], however in this review we would like to highlight several successful strategies applied to integrate MoS 2 with carbon, which could be used to improve performance of other 2D materials in BLI energy storage systems.…”

“…Previously described composites had limited interface contact between TMDC and carbon. Rationally constructing TMDC/carbon hybrid architecture was proven to be a successful approach to maximize the heterointerface between TMDC and carbon and gain high rate capability and long cycle life [116]. Novel hierarchically structured nanotubes were synthesized by a onepot solvothermal synthesis coupled with in situ carbonization of organic solvent ( Figure 11).…”

“…The MoS 2 :C superstructure nanotubes delivered an initial discharge capacity of 620 mAh g −1 with a Coulombic efficiency of 84% at the current density of 200 mA g −1 and maintained a reversible discharge capacity of 477 mAh g −1 after 200 cycles (Figure 11(f)-(i)). Importantly, the discharge capacity of 415 mAh g −1 after 200 cycles was observed even at high current density of 1000 mA g −1 [116]. Many advantages of magnesium-ion batteries (MIBs) originate from the divalent nature and small ionic size of Mg 2+ ion (Figure 9(b)).…”
