The shortage of traditional energy and the deterioration of environment forced people to develop novel energy storage devices for the replacement of traditional energy sources: coal, oil and natural gas. Lithium-ion batteries have been considered as an effective energy storage and conversion devices in the applications of various electronic products because of high energy density, long-life cycle, facile preparation, low cost, and no-pollution since their birth. However, the graphite as an anode material has a low theoretical capacity (372 mAh g-1). This greatly limits the wide applications in the field of electronic devices and hybrid electric vehicles. Transition metal sulfides are considered as ideal anode materials due to their high theoretical capacity, abundance, environmental-friendliness. However, some shortcomings such as low conductivity, the pulverization of the electrode materials, and the agglomeration of the nanoparticles contribute to disappointed electrochemical performance of a fast decay in specific capacity, low rate capability, as well as poor cycling stability. The effective strategy of the preparation of the porous nanocomposites with a unique structure is favorable for alleviating the volume-change, and preventing the pulverization of the electrode materials. In addition, the agglomeration of the active materials can be prevented, and the electrode materials can be significantly improved by the combination of the graphene with a high conductivity to form the nanocomposites. The synergy effect among the materials in the nanocomposites leads to the excellent electrochemical performance of the high specific capacity, good rate capability as well as high cycling stability. In this study, the three-dimensional porous nanocomposites are synthesized by the combination of the transition metal sulfides with the three-dimensional graphene, and the study on its electrochemical performance is made when the nanocomposites act as anode materials for the lithium ion batteries.(1) We synthesized Zinc sulfide (ZnS) nanoparticles and Zinc sulfide@reduced graphene oxide (rGO) nanocomposites with three-dimensional nanostructure via a simple hydrothermal method. Compared with the ZnS nanoparticles, as an anode for lithium ions batteries, the nanocomposites electrode show some better electrochemical properties in higher specific capacity, and better rate capability and cycling stability. They show a favorable specific capacity of 1130.5 mAh g-1 after repeated 200 cycles at a current density of 100 mA g-1, with the capacity retention of 66.7%. The morphology and compositions of the composites before and after cycling were studied. The better electrochemical performance of the nanocomposites can be ascribed to its unique morphology, nanostructure, the synergistic reaction between the ZnS nanoparticles and three-dimensional cross-linked rGO in the lithium-ion insertion/extraction process.(2) We synthesized Cobalt sulfide (CoS)@reduced graphene oxide (rGO) nanocomposites with three-dimensional nanostructure by the dipping treatment followed by a simple hydrothermal method. The nanocomposites with three different loading of CoS were prepared by the change of cobaltous chloride (CoCl2·6H2O) mass. The CoS@rGO-1 electrode shows the best electrochemical performance in specific capacity, rate capability, and cycling stability as an anode for lithium ions batteries. When used as an anode material, Cobalt sulfide@reduced graphene oxide nanocomposites show remarkable electrochemical performance. They deliver an outstanding specific capacity of 1262.5 mAh g-1 at 100 mA g-1 after 100 cycles, and a good rate capability of 710.8 mAh g-1 at 2000 mA g-1. These excellent electrochemical performances are mainly ascribed to the reduced graphene oxide in the nanocomposites. The 3D network-like framework could provide a high specific surface area with more active sites. And it not only promotes the fast diffusion of the electrons and ions, but effectively accommodates the volume-expansion during the lithium ions insertion/extraction process.(3) We prepared Co9S8@MoS2/rGO composites with core-shell nanostructure and Co9S8@rGO composites via a simple hydrothermal reaction. In contrast to Co9S8@rGO composites, Co9S8@MoS2/rGO anode show improved electrochemical performance in terms of specific capacity, rate capability, as well as cycling stability. Co9S8@MoS2/rGO anode could deliver a much higher specific capacity of 1986.7 mAh g-1 mAh g-1 than 970.5 mAh g-1 of the Co9S8@rGO anode after repeated 200 cycles at a current density of 100 mA g-1, and its capacity retention is 93.6% during the fast discharge/charge process for lithium ions batteries. The morphology and compositions of the composites before and after the repeated cycling were investigated. The three-dimensional framework of the core-shell structure for the Co9S8@MoS2/rGO plays a vital part in the superior electrochemical performance. (4) We prepared a three-dimensional nanofin-structured anode material consisting of reduced graphene oxide and metal sulfide, which is a good strategy to address the above problems. The present anode is composed of Ni7S6/MnS2 micro/nanosheets uniformly anchored on both sides of the reduced graphene oxide synthesized via in situ the sulfuration of NiMn2O3(OH)4@reduced graphene oxide precursor. Ni7S6/MnS2@reduced graphene oxide nanocomposites show a good electrochemical performance including a reversible capability of 1010 mAh g-1 at 0.5 A g-1 over 500 cycles, and a superior rate capability. This method can also be applied to the preparation of other sulfides such as NiS2@reduced graphene oxide, as well as Ni7S6/CoS2@reduced graphene oxide. Electrode characterizations before and after tests show that the porous composite as anode materials can well accommodate to the huge volume-change, and promote the electrons mobility and the diffusion of the ions in the discharge/charge process. The simple preparation method and the excellent electrochemical performance of the Ni7S6/MnS2@reduced graphene oxide would enable them to be a promising anode material in the potential applications for lithium-ion batteries.
