“…According with the discharge profiles in long-term cycle, the capacity improvement in rate test is also attributed to the lithiation platform around 1.0 ~1.5 V in ZTAS@C (Figure 4b and 4c). In contrast with the previous works related to Zn-/Sn-and Sb-based composites, [11][12][13][14][15][16]20,22,23,34] the ZTAS@C also shows a comparable and excellent rate capability as LIBs anode (Figure 4d and Table S1). That superior specific capacity, cycle stability and rate capability of ZTAS@C submicron box composite can be revealed from the electrochemical impedance spectroscopy (EIS) in Figure 4e.…”

“…The dramatic decrease of special capacity when activated by 0.1 A g À 1 current density during the first several cycles is associated with irreversible Liions losses for the formation of SEI film and decomposition of SnS. In addition, referring to, [12,15,16,28,31] the formation of Li x S phase also might be responsible for the slow capacity decay during the initial charge-discharge cycling. However, it is noted that the ZTAS@C anode still demonstrates the high reversible capacity of 581 mAh g À 1 after 100 cycles with the high CE value around almost 100% over the course.…”

“…Therefore, various strategies have been proposed to exert the special capacity superiority of Zn-, Sn-and Sb-based composites as LIBs anodes. [12,15,20,22] Coupling sulfides with carbon materials is effective to enhance inferior electrode electron conductivity of metal chalcogenides, thus to improve their charge transfer kinetics. [16,[23][24][25] Especially, due to nano-micro structure, uniform nano-size and synergetic effect of components, the design and synthesis of hierarchical hollow nanostructure can significantly strengthen the electrochemical properties of those coupling sulfides composites.…”

In this work, a hierarchical ZnS‐SnS‐Sb2S3@C (ZTAS@C) submicron box has been successfully prepared via a facile cation‐exchange strategy and is used as advanced anode for Li‐ion batteries. The composition and morphology of the as‐prepared samples are measured by XRD, SEM and TEM, respectively. In addition, the as‐synthesized hollow ZTAS@C architecture delivers a rate capability of 1001, 862, 765, 621, and 419 mAh g−1 at 0.2, 0.5, 1.0, 2.0, and 4.0 A g−1, respectively, and maintains reversible specific capacity of 581 mAh g−1 after 100 cycles at 1.0 A g−1 with the high CE value around almost 100%. Since 1 mol Sb2S3 could hold 4.8 times more Li+ ions than ZnS, the as‐synthesized ZTAS@C delivers 2∼3 times more specific capacity than the un‐treated ZnS‐SnS@C sample without cation‐exchange during electrochemical testing. Moreover, the cycled ZTAS@C could maintain a relatively complete microscopic morphology of the submicron box with a lower electrode expansion rate of ∼131%. Owing to synergistic effects between ZnS‐SnS‐Sb2S3, such as stable structure from ZnS, faster ionic conductivity from SnS and higher capacity from Sb2S3 (theoretically 947 mAh/g), ZTAS@C anode showed excellent electrochemical enhancements as using for LIBs anode. Therefore, the cation exchange strategy should be a facile way to improve the rate performance and cycle stability of multi‐metals sulfide composites.

Interface design is generally helpful to ameliorate the electrochemical properties of electrode materials but challenging as well. Herein, in situ sulfur-mediated interface engineering is developed to effectively raise the kinetics properties of the SnS nanosheet anodes, which is realized by a synchronous reduction and carbon deposition/doping process. The sulfur in the raw SnS2 directly induces the sulfur-doped amorphous carbon layer onto the in situ reduced SnS nanosheet. In situ and ex situ electrochemical characterizations suggest that the sulfur-mediated interface layer can enhance the reversibility and kinetics properties, promote the ion/electron swift delivery, and maintain the configurational wholeness of the SnS nanosheet anodes. Consequently, a relatively high Li-storage capacity of 922 mAh g–1 and Na-storage capacity of 349 mAh g–1 at 1.0 A g–1 even after 1000 and 300 long-term cycles are achieved, respectively. The facile method and excellent performance suggest the effective interface tuning for developing the SnS-based anodes for batteries and beyond.

“…XPS analysis was performed to reveal the valence states of SnS@N-C/rGO. The Sn 3d XPS spectrum (Figure c) shows two distinct peaks of Sn 2+ (3d 3/2 , 487.2 eV; and 3d 5/2 , 495.6 eV), indicating high phase purity of SnS. − The peaks in S 2p XPS profile (Figure d) can be divided into several peaks, including those of S 2– (2p 3/2 , 161.4 eV; and 2p 1/2 , 162.3 eV), S–C (163.9 eV), and S–O/SO (168.7 eV). , Differently, the S–O/SO bond is absent in the S 2p spectrum of the SnS/rGO (Figure S5a). The comparison demonstrates the tight bonding connection between N-doped carbon coating and SnS nanograins.…”

Tin monosulfide (SnS), showing great prospect for lithium-ion batteries (LIBs), is restricted by its low conductivity and severe volume change during cycling. Moreover, severe agglomeration of SnS grains is ineluctable in the synthesis processes. Herein, the composite with both amorphous carbon and reduced graphene oxide (rGO) has been considered as an effective strategy to solve these problems. We have constructed a layered-structure of SnS particles anchored on rGO sheets with Ndoped carbon coated on the grain surface. This dual-carbon structure successfully achieves uniform dispersion and restricted growth of grains, which is demonstrated by XRD, SEM, and TEM analyses. Besides, the introduction of N-doped carbon coating and rGO supporting effectively mitigates drastic volume change as well as enables excellent electronic conductivity of SnS during discharge/charge processes. Therefore, as anode for LIBs, the N-doped carbon coated SnS/rGO composite (SnS@N-C/rGO) shows outstanding rate capability and cycling performance. At 0.1 A g −1 , it delivers a high initial reversible capacity of 1068.9 mAh g −1 . Even at 1.0 A g −1 , it also shows a high initial reversible capacity of 885.3 mAh g −1 and maintains 824 mAh g −1 after 550 cycles. Thus, the dual-carbon modification is a feasible strategy to promote the electrochemical properties of SnS and contribute alternative anodes for LIBs.
