Molybdenum disulfide (MoS2), which possesses a layered structure and exhibits a high theoretical capacity, is currently under intensive research as an anode candidate for next generation of Li‐ion batteries. However, unmodified MoS2 suffers from a poor cycling stability and an inferior rate capability upon charge/discharge processes. Herein, a unique nanocomposite comprising MoS2 nanothorns epitaxially grown on the backbone of carbon nanotubes (CNTs) and coated by a layer of amorphous carbon is synthesized via a simple method. The epitaxial growth of MoS2 on CNTs results in a strong chemical coupling between active nanothorns and carbon substrate via CS bond, providing a high stability as well as a high‐efficiency electron‐conduction/ion‐transportation system on cycling. The outer carbon layer can well‐accommodate the structural strain in the electrode upon lithium‐ion insertion/extraction. When employed as an anode for lithium storage, the prepared material exhibits remarkable electrochemical properties with a high specific capacity of 982 mA h g−1 at 0.1 A g−1, as well as excellent long‐cycling stability (905 mA h g−1 at 1 A g−1 after 500 cycles) and superior rate capability, confirming its potential application in high‐performance Li‐ion batteries.

Improving the performance of anode materials for lithium-ion batteries (LIBs) is ah otly debated topic. Herein, hollow NiÀCo skeleton@MoS 2 /MoO 3 nanocubes (NCM-NCs), with an average size of about1 93 nm, have been synthesized through af acile hydrothermal reaction. Specifically, MoO 3 /MoS 2 composites are grown on NiÀCo skeletons derived from nickel-cobaltP russian blue analogue nanocubes (NiÀCo PBAs). The NiÀCo PBAs were synthesized through a precipitation method and utilized as self-templates that provided al arger specific surface area for the adhesion of MoO 3 /MoS 2 composites. According to Raman spectroscopy results,a s-obtained defect-richM oS 2 is confirmed to be a metallic 1T-phase MoS 2 .F urthermore, the average particle size of NiÀCo PBAs ( % 43 nm) is only about one-tenth of the previously reported particles ize ( % 400 nm). If assessed as anodes of LIBs, the hollow NCM-NC hybrids deliver an excellent rate performance and superiorc ycling performance (with an initial discharge capacity of 1526.3 mAh g À1 and up to 1720.6 mAh g À1 after 317 cycles under ac urrent density of 0.2 Ag À1 ). Meanwhile, ultralong cycling life is retained, even at high current densities (776.6 mAh g À1 at 2Ag À1 after 700 cycles and 584.8 mAh g À1 at 5Ag À1 after 800 cycles). Moreover,a tarate of 1Ag À1 ,t he average specific capacity is maintained at 661 mAh g À1 .T hus,t he hierarchical hollow NCM-NC hybridsw ith excellent electrochemical performance are ap romising anodem aterial for LIBs.[a] J.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

A nanotubular composite composed of titania nanotubes coated with a thin layer of molybdenum trioxide was fabricated by employing natural cellulose (ordinary filter paper) as a template. The cellulose nanofibers were precoated with an ultrathin titania gel film by the surface sol–gel process. These nanofibers were then further coated with double layers of a positively charged poly(diallyldimethylammonium chloride) layer and a negatively charged polyoxomolybdate cluster layer deposited by the layer‐by‐layer self‐assembly approach. The as‐prepared composite was calcined in air to yield a series of MoO3/TiO2 nanocomposites with varied contents of MoO3. As an anode material for lithium‐ion batteries, the composite showed improved electrochemical performances, such as excellent reversible capacity, cycling stability, and rate capability; these benefited from the hierarchical three‐dimensional nanostructures of the composites derived from the cellulose substance, and the buffering effect of the robust titania nanotubes to maintain the structural integrity of the electrode.
