Initial Discharge

Fe 3 O 4/carbon nanotubes (CNTs) nanocomposites are successfully prepared by a facile hydrothermal method, without any reducing agents. SEM shows that the CNTs are dispersed well in the Fe 3 O 4 nanoparticles of 50 to 100 nm in size. The electrochemical properties of the prepared nanocomposites as anode materials are further evaluated by galvanostatic charge/discharge cycling and cyclic voltammetry (CV). Results show that the nanocomposites display an initial discharge capacity of 1421 mAh⋅g-1 and maintain 1100 mAh⋅g-1 up to 40 cycles in the voltage of 0.005–3.0 V at 100 mAh⋅g-1. When the current density is to 0.5, 1, 2, 5 and 1 C, the nanocomposites still exhibit discharge capacity of 1615.8, 817.0, 585.0, 391.0 and (585.0 ± 45.0) mAh⋅g-1, respectively, which are potential for anode materials in lithium-ion batteries.

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.
