“…They noticed that the Li adsorption energies on monolayer Sb vary from 1.70 to 1.91 eV with a charge transfer of ~0.85|e|, indicating the adsorption is relatively strong, as shown in Figure 6b,c. It is interesting to note that the semi-metallic monolayer Sb exhibits a semiconductor to metal transition (see Figure 6d) upon Li intercalation, accompanied by significant electron transfer from Li to Sb, consistent with earlier reports on different 2D materials [51]. The study also investigated the diffusion barrier of Li atoms on the surface of monolayer Sb and observed fast diffusion with a low energy barrier of 0.20 eV.…”

To mitigate the use of fossil fuels and maintain a clean and sustainable environment, electrochemical energy storage systems are receiving great deal of attention, especially rechargeable batteries. This is also associated with the growing demand for electric vehicles, which urged the automotive industries to explore the capacities of new materials for use in lithium–ion batteries (LIBs). Graphite is still employed as an anode in large majority of currently available commercial LIBs preserving their better cyclic stability despite enormous research efforts to identify viable alternatives with improved power and energy density. From this point of view, antimony acts as a promising material because it has good theoretical capacity, high volumetric capacity, good reactivity with lithium and good electronic conductivities. Recently, there have been many works that focused on the development of antimony as an alternative anode. This review tries to give a bird’s eye view comprising the experimental and theoretical insights on the developments in the direction of using antimony and antimony composites as anodes for rechargeable Li.

“…Afterwards, mechanical isolation [73], liquid-phase exfoliation [74], aqueous shear exfoliation [75], molecular beam epitaxy [76], van der Waals epitaxy growth [77] and so forth have been demonstrated to obtain high-quality few-layer Sb exfoliated nanosheets. From the view of first-principles calculations, antimonene exhibits high specific capacity, a small diffusion barrier and low lattice expansion as an anode for SIBs [78,79] and shows relatively small structure deformation upon Li adsorption [80]. Notably, Su et al proposed a trilayer graphene/antimonene/graphene heterostructure as a potential anode, and their calculation results confirmed that a heterostructure can provide strong binding with Na and a low-migration barrier for Na (Figure 4c-h) [81].…”

Engineering Nanostructured Antimony-Based Anode Materials for Sodium Ion Batteries

et al. 2021

View full text Add to dashboard Cite

Sodium-ion batteries (SIBs) are considered a potential alternative to lithium-ion batteries (LIBs) for energy storage due to their low cost and the large abundance of sodium resources. The search for new anode materials for SIBs has become a vital approach to satisfying the ever-growing demands for better performance with higher energy/power densities, improved safety and a longer cycle life. Recently, antimony (Sb) has been extensively researched as a promising candidate due to its high specific capacity through an alloying/dealloying process. In this review article, we will focus on different categories of the emerging Sb based anode materials with distinct sodium storage mechanisms including Sb, two-dimensional antimonene and antimony chalcogenide (Sb2S3 and Sb2Se3). For each part, we emphasize that the novel construction of an advanced nanostructured anode with unique structures could effectively improve sodium storage properties. We also highlight that sodium storage capability can be enhanced through designing advanced nanocomposite materials containing Sb based materials and other carbonaceous modification or metal supports. Moreover, the recent advances in operando/in-situ investigation of its sodium storage mechanism are also summarized. By providing such a systematic probe, we aim to stress the significance of novel nanostructures and advanced compositing that would contribute to enhanced sodium storage performance, thus making Sb based materials as promising anodes for next-generation high-performance SIBs.

“…Su et al showed that nano-scale modification is an alternative strategy to improve the cycling performance of Sb in LIBs. 264 They systematically investigated the Li adsorption of monolayer antimonene using first-principles calculations based on vdW corrected DFT. b-Phase monolayer antimonene with a buckled hexagonal structure was selected for their calculation because of its higher thermodynamic stability as shown in Fig.…”
