“…10,11,14,38,39 The additional oxidation peaks at around 1.8 V observed in all of the anodic potential scans can be assigned to the lithium deintercalation from SnS 2 layers without phase decomposition. These similar oxidation/reduction peaks are also clearly shown in the CV curve of pure SnS 2 (Fig.…”

SnS 2 nanoparticle-loaded graphene nanocomposites were synthesized via one-step hydrothermal reaction. Their electrochemical performance was evaluated as the anode for rechargeable lithium-ion batteries after thermal treatment in an Ar environment. The electrochemical testing results show a high reversible capacity of more than 800 mA h g À1 at 0.1 C rate and 200 mA h g À1 for upto 5 C rate. The cells also exhibit excellent capacity retention for up to 90 cycles even at a high rate of 2 C. This electrochemical behavior can be attributed to the well-defined morphology and nanostructures of these as-synthesized nanocomposites, which is characterized by high-resolution transmission electron microscopy and electron energy-loss spectroscopy.

“…Among them, Li-Sn alloy compounds have attracted great interest due to their theoretical specific capacity up to 992 mAh/g [1]. SnS 2 was reported to be used as a novel anode material for lithium-ion batteries as it transforms to Li-Sn alloys during charge-discharge process [2,3]. However, even though SnS 2 exhibits high initial discharge capacity, the large volume changes and loss of electrical contact during lithium intercalation and deintercalation result in capacity fading of the compound.…”

Graphene-SnS 2 nanocomposites were prepared via a solvothermal method with different loading of SnS 2 . The nanostructure and morphology of the samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), and transmission electron microscopy (TEM). The XRD patterns revealed that hexagonal SnS 2 was obtained. SEM and TEM results indicated that SnS 2 particles distributed homogeneously on graphene sheets. The electrochemical properties of the samples as active anode materials for lithium-ion batteries were examined by constant current charge-discharge cycling. The composite with weight ratio between graphene and SnS 2 of 1:4 had the highest rate capability among all the samples and its reversible capacity after 50 cycles was 351 mAh/g, which was much higher than that of the pure SnS 2 (23 mAh/g). With graphene as conductive matrix, homogeneous distribution of SnS 2 nanoparticles can be ensured and volume changes of the nanoparticles during the charge and discharge processes can be accomodated effectively, which results in good electrochemical performance of the composites.

“…The result indicated that the smaller size and special structure were helpful to improve the electrochemical properties. Zai et al [30] have reported RedEmbroidery-Ball-like SnS 2 assembled by the intertwining of SnS 2 silks with a thickness of about 10 nm and showed high lithium storage capacity of above 500 mAhg −1 after 100 cycles. The high performance of these SnS 2 microspheres was ascribed to their unique 3D hierarchical structures assembled by ultrathin nanosheets.…”

Controlled growth of flower-like SnS 2 hierarchical structures was obtained by a facile hydrothermal method with the mixture solution of SnCl 4 and L-cysteine (L-cys). The results of electron microscopy and X-ray diffraction characterization indicated that morphology, structure, and crystallinity of the hierarchical structures were seriously dependent on the concentration of L-cys, mole ratio of Sn 4+ to L-cys and temperature. Electrochemical tests demonstrated that the flower-like SnS 2 hierarchical structures exhibited superior cycling performance for anode materials of Li-ion batteries, which retained a high reversible capacity of 418 mAhg −1 and stable cyclic retention at 100th cycle. These results show that the flower-like SnS 2 hierarchical structures were suitable for using as anode material in lithium-ion batteries.
