Half and full cell researches of ternary MoS2/graphene/CNT aerogel compostie for enhanced lithium storage performances

Abstract Without using any templates, a ternary MoS2/graphene/carbon nanotubes (MoS2/GN/CNT) aerogel compostie is prepared by convenient hydrothermal synthesis method. The free-standing MoS2/GN/CNT aerogel can be cut directly as binder free electrodes in lithium-ion batteries. The MoS2/GN/CNT electrodes can hold as high as 695 and 579 mAh g−1 discharge capacities after 200 cycles at 200 mA g−1 in MoS2/GN/CNT//Li half cells and MoS2/GN/CNT//LiCoO2 full-cells, respectively. The strengthened electrochemical properities are owed by the thin GN/CNT layers and their jagged and wrinkled surfaces, which can enhance the composite conductivity and shorten the Li+ diffusion distance, as well as buffer the volume change of electrodes druing the charge-discharge cycles.

Nanoscale engineering of regular structured materials is immensely demanded in various scientific areas. In this work, vertically oriented TiO2 nanotube arrays were grown by self-organizing electrochemical anodization. The effects of different fluoride ion concentrations (0.2 and 0.5 wt% NH4F) and different anodization times (2, 5, 10 and 20 h) on the morphology of nanotubes were systematically studied in an organic electrolyte (glycol). The growth mechanisms of amorphous and anatase TiO2 nanotubes were also studied. Under optimized conditions, we obtained TiO2 nanotubes with tube diameters of 70–160 nm and tube lengths of 6.5–45 μm. Serving as free-standing and binder-free electrodes, the kinetic, capacity, and stability performances of TiO2 nanotubes were tested as lithium-ion battery anodes. This work provides a facile strategy for constructing self-organized materials with optimized functionalities for applications.

High energy density and rechargeable lithium ion batteries are attracting widely interest in renewable energy fields. The preparation of the high performance materials for electrodes has been regarded as the most challenging and innovative aspect. By utilizing a facile combustion synthesis method, pure nanostructure LiNi0.5Mn1.5O4 cathode material for lithium ion batteries were successfully fabricated. The crystal phase of the samples were characterized by X-Ray Diffraction, and micro-morphology as well as electrochemistry properties were also evaluated using FE-SEM, electrochemical charge-discharge test. The result shows the fabricated LiNi0.5Mn1.5O4 cathode materials had outstanding crystallinity and near-spherical morphologies. That obtained LiNi0.5Mn1.5O4 samples delivered an initial discharge capacity of 137.2 mAhg-1 at the 0.1 C together with excellent cycling stability and rate capability as positive electrodes in a lithium cell. The superior electrochemical performance of the as-prepared samples are owing to nanostructure particles possessing the shorter diffusion path for Li+ transport, and the nanostructure lead to large contact area to effectively improve the charge/discharge properties and the rate property. It is demonstrated that the as-prepared nanostructure LiNi0.5Mn1.5O4 samples have potential as cathode materials of lithium-ion battery for future new energy vehicles.
