“…Lithium ion batteries (LIBs) are being widely used in the electric vehicles and energy storage fields (Wu et al, 2017; Chen et al, 2018b,c; Cui et al, 2018; Zhang et al, 2018; Zheng et al, 2018). However, the commercial graphite anode is far to meet the requirements of the high-performance LIBs due to its low theoretical capacity (Ryu et al, 2016; Li et al, 2017b; Yan et al, 2017; Wang et al, 2018).…”

SnS2 nanosheets/reduced graphene oxide (rGO) composite was prepared by reflux condensation and hydrothermal methods. In this composite, SnS2 nanosheets in-situ grew on the surface of rGO nanosheets. The SnS2/rGO composite as anode material was investigated both in lithium ion battery (LIB) and sodium ion battery (SIB) systems. The capacity of SnS2/rGO electrode in LIB achieved 514 mAh g−1 at 1.2 A g−1 after 300 cycles. Moreover, the SnS2/rGO electrode in SIB delivered a discharge capacity of 645 mAh g−1 at 0.05 A g−1; after 100 cycles at 0.25 A g−1, the capacity retention still keep 81.2% relative to the capacity of the 6th cycle. Due to the introduction of rGO in the composite, the charge-transfer resistance became much smaller. Compared with SnS2/C electrode, SnS2/rGO electrode had higher discharge capacity and much better cycling performance.

“…During the first discharge process of the ZnS electrode, a small cathodic peak appeared around 0.7 V, which was related to the reduction reaction of ZnS to generate Li 2 S and metallic Zn. The large and broad peak in the voltage range of 0.01–0.4 V corresponds to the further sequential lithiation reactions of Zn to form various Li x Zn phases, eventually forming the LiZn phase (Zn → LiZn 4 → LiZn) in the fully lithiated state [43,44]. The cathodic peaks are partly ascribed to the SEI layer formation on the electrode surface, which was responsible for part of the irreversible capacity.…”

“…Unfortunately, the application of the standalone S-based electrode is impractical because of its low electronic conductivity (~5 × 10 −22 S cm −1 ), the dissolution of Li polysulfides, and the large volume expansion upon extended cycling. Therefore, many ZnS-based composites have been reported as high-performance anode materials owing to their very high theoretical specific capacities (829 mA h g −1 ), but their electrochemical performance remains unsatisfactory, as shown in Table S1 [42,43,44,45,46,47,48,49]. Moreover, the lithiation/delithiation potential of an active ZnS anode is much higher than the reaction potential of metallic Li, preventing the safety concerns associated with Li plating, which eventually results in dendrite growth and short circuiting [50,51].…”

Enhanced Cycle Stability of Zinc Sulfide Anode for High-Performance Lithium-Ion Storage: Effect of Conductive Hybrid Matrix on Active ZnS

Zinc sulfide (ZnS) nanocrystallites embedded in a conductive hybrid matrix of titanium carbide and carbon, are successfully fabricated via a facile high-energy ball-milling (HEBM) process. The structural and morphological analyses of the ZnS-TiC-C nanocomposites reveal that ZnS and TiC nanocrystallites are homogeneously distributed in an amorphous carbon matrix. Compared with ZnS-C and ZnS composites, the ZnS-TiC-C nanocomposite exhibits significantly improved electrochemical performance, delivering a highly reversible specific capacity (613 mA h g−1 over 600 cycles at 0.1 A g−1, i.e., ~85% capacity retention), excellent long-term cyclic performance (545 mA h g−1 and 467 mA h g−1 at 0.5 A g−1 and 1 A g−1, respectively, after 600 cycles), and good rate capability at 10 A g−1 (69% capacity retention at 0.1 A g−1). The electrochemical performance is significantly improved, primarily owing to the presence of conductive hybrid matrix of titanium carbide and amorphous carbon in the ZnS-TiC-C nanocomposites. The matrix not only provides high conductivity but also acts as a mechanical buffering matrix preventing huge volume changes during prolonged cycling. The lithiation/delithiation mechanisms of the ZnS-TiC-C electrodes are examined via ex situ X-ray diffraction (XRD) analysis. Furthermore, to investigate the practical application of the ZnS-TiC-C nanocomposite, a coin-type full cell consisting of a ZnS-TiC-C anode and a LiFePO4–graphite cathode is assembled and characterized. The cell exhibits excellent cyclic stability up to 200 cycles and a good rate performance. This study clearly demonstrates that the ZnS-TiC-C nanocomposite can be a promising negative electrode material for the next-generation lithium-ion batteries.

“…These problems are mainly related to the anode and cathode of the battery. As far as anode materials are concerned, commercial graphite on the market today is unable to meet the increasing energy density requirements due to its lower capacity (about 372 mAh g −1 ) (Chen et al, 2018b; Xiao et al, 2018). In the past few decades, researchers developed many high-capacity and structurally stable anode materials, among which tin oxide anode materials with low discharge potential and natural abundance, received extensive attention and become a strong competitor for the next generation of lithium-ion battery anode materials (Chou et al, 2009; Sahoo and Ramaprabhu, 2018; Woo et al, 2018; Ye et al, 2019).…”

Tin-based anode materials with high capacity attract wide attention of researchers and become a strong competitor for the next generation of lithium-ion battery anode materials. However, the poor electrical conductivity and severe volume expansion retard the commercialization of tin-based anode materials. Here, SnO 2 -SnS 2 @C nanoparticles with heterostructure embedded in a carbon matrix of nitrogen-doped graphene (SnO 2 -SnS 2 @C/NG) is ingeniously designed in this work. The composite was synthesized by a two-step method. Firstly, the SnO 2 @C/rGO with a nano-layer structure was synthesized by hydrothermal method as the precursor, and then the SnO 2 -SnS 2 @C/NG composite was obtained by further vulcanizing the above precursor. It should be noted that a carbon matrix with nitrogen-doped graphene can inhibit the volume expansion of SnO 2 -SnS 2 nanoparticles and promote the transport of lithium ions during continuous cycling. Benefiting from the synergistic effect between nanoparticles and carbon matrix with nitrogen-doped graphene, the heterostructured SnO 2 -SnS 2 @C/NG further fundamentally confer improved structural stability and reaction kinetics for lithium storage. As expected, the SnO 2 -SnS 2 @C/NG composite exhibited high reversible capacity (1201.2 mA h g −1 at the current rate of 0.1 A g −1 ), superior rate capability and exceptional long-life stability (944.3 mAh g −1 after 950 cycles at the current rate of 1.0 A g −1 ). The results demonstrate that the SnO 2 -SnS 2 @C/NG composite is a highly competitive anode material for LIBs.
