“…While, SnSb:Ni shows moderately high fading than SnSb:Fe alloy, it could be due to the excess amount of Sn shown by XRD and involves some structural variation in the Sn and Sb lattice which is observed from FTIR, Raman and thermal analysis, which resulted in mechanical pulverization of the electrode and poor cycling performance caused be large volume expansion during lithiation process of electrode [37]. However, the reversible capacity value is higher than the other reported alloys [37,46,48,49].…”

“…Many kinds of carbon materials, such as amorphous carbon, graphene, carbon nanotube, carbon nanofiber, graphite,, have been extensively introduced to further improve the cycling performance and rate capability of the M‐Sn alloy anodes for LIBs. For instance, B. Scrosati group reported an electrochemical investigation of a Sn‐Co‐C ternary electrode in a Sn 31 Co 28 C 41 /LiFePO 4 full cell with output voltage at around a 3V level and good cycling performance, as shown in Figure a,b .…”

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.

“…Lithium (Li)-ion batteries (LIBs) have become the most popular class of energy storages and power sources for portable electronics and mobile devices because of their high energy density, rate capability, cycle stability, and market availability [1,2]. To cope with the rapidly increasing challenges by other classes of energy storages and power sources, it is urgent to develop higher performance electrocatalytic anodes to extend the application scopes of LIBs, especially in the fast-growing fields of electric vehicles and renewable energies [3,4].…”

“…First, the large volume change of FeSn 2 alloy nanoparticle during the lithiation-delithiation process induce increasing inner stress, that cause pulverization of the active electrocatalyst, thereby inducing loss of electrical connection with the current collectors [2,10,11]. Though stannide alloy anodes with Fe or Co as electrocatalytically inactive act as buffering agent (e.g., FeSn 2 and CoSn 2 ) are capable of improving the cyclability of the LIBs by redistributing the volume change-induced fragmentation, yet the minimization of pulverization of the nanoparticles is still a major concern that needs to be addressed [2,12]. Second, the new surfaces formed by the pulverized active electrocatalyst consume higher amount of Li, leading to the formation of solid-electrolyte interphase (SEI) that subsequently passivates the anode and increases the undesired electrochemical resistance [11].…”

Core/shell-structured FeSn2/onion-like carbon (FeSn2/OLC) nanocapsules of confined size range of sub-50 nm are synthesized via an in-situ arc-discharge process, and are evaluated in comparison with FeSn2 nanoparticles as an improved stannide-based electrocatalytic anode material for Li-ion batteries (LIBs). The in-situ arc-discharge process allows a facile one-pot procedure for forming crystalline FeSn2 stannide alloy nanoparticle cores coated by defective OLC thin shells in addition to a confined crystal growth of the FeSn2 nanoparticle cores. The LIB cells assembled using the FeSn2/OLC nanocapsules as the electrocatalytic anodes exhibit superior full specific discharge capacity of 519 mAh·g−1 and specific discharge capacity retention of ~62.1% after 100 charge-discharge cycles at 50 mA·g−1 specific current. The electrochemical stability of FeSn2/OLC nanocapsules is demonstrated from the good cycle stability of the LIBs with a high specific discharge capacity retention of 67.5% on a drastic change in specific current from 4000 to 50 mA·g−1. A formation mechanism is proposed to describe the confined crystal growth of the FeSn2 nanoparticle cores and the formation of the FeSn2/OLC core/shell structure. The observed electrochemical performance enhancement is ascribed to the synergetic effects of the enabling of a reversible lithiation process during charge-discharge of the LIB cells by the FeSn2 nanoparticle cores as well as the protection of the FeSn2 nanoparticle cores from volume change-induced pulverization and solid electrolyte interphase-induced passivation by the OLC shells.
