Synthesis Strategy

Three-dimensional V2O5 hollow structures have been prepared through a simple synthesis strategy combining solvothermal treatment and a subsequent thermal annealing. The V2O5 materials are composed of microspheres 2–3 μm in diameter and with a distinct hollow interior. The as-synthesized V2O5 hollow microspheres, when evaluated as a cathode material for lithium-ion batteries, can deliver a specific capacity as high as 273 mAh·g−1 at 0.2 C. Benefiting from the hollow structures that afford fast electrolyte transport and volume accommodation, the V2O5 cathode also exhibits a superior rate capability and excellent cycling stability. The good Li-ion storage performance demonstrates the great potential of this unique V2O5 hollow material as a high-performance cathode for lithium-ion batteries.

Storage Behavior

Rationally engineered anode materials with high specific capacities and rate capability are essential for lithium-ion batteries (LIBs). In this paper, a free-standing anode composed of Co3S4 nanosheets arrays and carbon cloth (abbreviated Co3S4@CC) was fabricated for high performance LIBs. The three-dimensional (3D) porous carbon cloth could not only improve the conductivity but also boost Li[Formula: see text] transfer and increase contact area for reactions. Besides, the porous thin Co3S4 nanosheets possessing strong interaction with carbon cloth by formation of C–S bond and high surface area could facilitate the mitigation of volume expansion and reduction of Li[Formula: see text] diffusion distance, coupling with efficient contact with electrolytes during cycling process. As expected, the freestanding Co3S4@CC anode presents pseudocapacitance-dominated storage behavior with a very high specific capacity of 847[Formula: see text]mAh g[Formula: see text] at 250[Formula: see text]mA g[Formula: see text] after 100 cycles and good rate capability for LIBs. This work provides an approach for designing metal sulfides with high capacities and rate capability for LIBs, especially flexible LIBs.

This paper reports the synthesis MoS2/graphene composite as an anode using commercial graphene as conductive enhancer and structural modifier. X-ray powder diffraction (XRD) and morphology details show that the as-synthesized MoS2/graphene composite has hexagonal structure and shows three-dimensional hierarchical network structure. The anode electrochemical properties of MoS2/graphene composite and pure MoS2 were measured and analyzed by galvanostatic charge–discharge cycling vs. Na/Na+ at different current densities in 0.05–3.0[Formula: see text]V. Compared to pure MoS2, MoS2/graphene composite demonstrates great specific capacity (509[Formula: see text]mAh[Formula: see text] at the current rate about 0.3 C), excellent rate capability (305[Formula: see text]mAh[Formula: see text] at the maximum current rate 5 C) and relatively good cycle-life (capacity reached 84% after 100 cycles). Moreover, the facile synthesis strategy of MoS2/graphene can provide a reference for designing other transition metal chalcogenides composites containing graphene for high performance SIBs.

Tubular Structures

Molybdenum disulfide (MoS2), a typical two-dimensional material, is a promising anode material for lithium-ion batteries because it has three times the theoretical capacity of graphite. The main challenges associated with MoS2 anodes are the structural degradation and the low rate capability caused by the low intrinsic electric conductivity and large strain upon cycling. Here, we design hierarchical MoS2 tubular structures internally wired by carbon nanotubes (CNTs) to tackle these problems. These porous MoS2 tubular structures are constructed from building blocks of ultrathin nanosheets, which are believed to benefit the electrochemical reactions. Benefiting from the unique structural and compositional characteristics, these CNT-wired MoS2 tubular structures deliver a very high specific capacity of ~1320 mAh g−1 at a current density of 0.1 A g−1, exceptional rate capability, and an ultralong cycle life of up to 1000 cycles. This work may inspire new ideas for constructing high-performance electrodes for electrochemical energy storage.
