“…Then for Sb 2 S 3 /ZnS sample, additional stronger peaks at 15.6°, 17.5°, 22.3°, 24.9°, 32.4°, 45.6°, 39.9°, and 43.0° appear, corresponding to (020), (120), (220), (130), (221), (420), (340), and (421) planes of Sb 2 S 3 (PDF 42–1393). For Sb/ZnS@C, XRD peaks centered at 23.7°, 28.7°, 40.1°, 41.9°, 51.6°, 59.4°, 65.9°, 68.5°, 75.3°, and 76.6° match well with (003), (012), (104), (110), (202), (024), (116), (122), (214), and (300) planes of Sb (PDF 35–0732), confirming the conversion process from Sb 2 S 3 to Sb in the annealing process due to the carbon reducing reaction. Moreover, Raman spectrum peaks at 1345 and 1580 cm −1 in Figure b reveal the existence of the carbon outer shell, corresponding to D band and G band.…”

Combining the advantage of metal, metal sulfide, and carbon, mesoporous hollow core-shell Sb/ZnS@C hybrid heterostructures composed of Sb/ZnS inner core and carbon outer shell are rationally designed based on a robust template of ZnS nanosphere, as anodes for high-performance sodium-ion batteries (SIBs). A partial cation exchange reaction based on the solubility difference between Sb S and ZnS can transform mesoporous ZnS to Sb S /ZnS heterostructure. To get a stable structure, a thin contiguous resorcinol-formaldehyde (RF) layer is introduced on the surface of Sb S /ZnS heterostructure. The effectively protective carbon layer from RF can be designed as the reducing agent to convert Sb S to metallic Sb to obtain core-shell Sb/ZnS@C hybrid heterostructures. Simultaneously, the carbon outer shell is beneficial to the charge transfer kinetics, and can maintain the structure stability during the repeated sodiation/desodiation process. Owing to its unique stable architecture and synergistic effects between the components, the core-shell porous Sb/ZnS@C hybrid heterostructure SIB anode shows a high reversible capacity, good rate capability, and excellent cycling stability by turning the optimized voltage range. This novel strategy to prepare carbon-layer-protected metal/metal sulfide core-shell heterostructure can be further extended to design other novel nanostructured systems for high-performance energy storage devices.

“…Based on the potential difference between redox couples of Zn 2+ /Zn (− 0.76 V vs. SHE) and Bi 3+ /Bi (0.31 V) [ 45 ], bismuth nanoparticles were anchored on the carbon matrix through a replacement reaction. The carbon matrix afforded an electronically conductive network and served as support to restrain the aggregation of bismuth nanoparticles [ 46 ]. Most importantly, the pores in the carbon matrix provided space to alleviate the mechanical strain of bismuth during lithiation/delithiation.…”

A novel bismuth–carbon composite, in which bismuth nanoparticles were anchored in a nitrogen-doped carbon matrix (Bi@NC), is proposed as anode for high volumetric energy density lithium ion batteries (LIBs). Bi@NC composite was synthesized via carbonization of Zn-containing zeolitic imidazolate (ZIF-8) and replacement of Zn with Bi, resulting in the N-doped carbon that was hierarchically porous and anchored with Bi nanoparticles. The matrix provides a highly electronic conductive network that facilitates the lithiation/delithiation of Bi. Additionally, it restrains aggregation of Bi nanoparticles and serves as a buffer layer to alleviate the mechanical strain of Bi nanoparticles upon Li insertion/extraction. With these contributions, Bi@NC exhibits excellent cycling stability and rate capacity compared to bare Bi nanoparticles or their simple composites with carbon. This study provides a new approach for fabricating high volumetric energy density LIBs.Electronic supplementary materialThe online version of this article (10.1007/s40820-018-0209-1) contains supplementary material, which is available to authorized users.

“…The third element (M′), such as Sb, Zn, Co,, and B could be both active and inactive for lithium storage. For example, the Sb is lithium‐active, which can alloy with lithium to form the Li 3 Sb in the alloying process, deriving a theoretical capacity of 660 mAh g −1 . Ternary Cu x Sb y Sn z alloy has been prepared by a ball‐milling technique and used as an anode in LIBs.…”

On account of the lower theoretical capacity of the traditional graphite, the development of reliable anode materials with high capacity and energy density for application in lithium‐ion batteries (LIBs) is zealously pursued to meet the ever‐increasing power demands for portable mobile devices or (hybrid) electronic vehicles. Recently, Sn‐based intermetallic compounds have attracted considerable research interests as the promising candidate anode materials for high‐performance LIBs in consideration of the high theoretical capacity of Sn (994 mAh g−1) and low operating voltage (below 0.6 V vs Li+/Li). The fabrication of Sn‐based intermetallic compounds is aiming at buffering the huge volumetric variation of Sn anode during lithiation/delithiation processes. Therefore, the rational construction of those anode materials with enhanced electrochemical performance is meaningful. This review is focusing on sum up the recent development in the structures, lithiation mechanism and electrochemical performances of various Sn‐based intermetallic compounds as anode materials in LIBs. The developments of modified methods for further enhancement of lithium storage performances of Sn‐based intermetallic compounds are also systematically summarized. We hope this review could provide a fundamental understanding of the Sn‐based intermetallic compounds for the application in LIBs.
