“…Gao et al utilized tailored engineering to exfoliate b-phase antimonene from bulk Sb, and evaluated it experimentally as an anode in LIBs. 265 Using ultrasonication with different power intensities, two types of tailored engineering, vertical direction and omnidirectional, were used to produce 2D antimonene and Sb nanoparticles (NPs). Both antimonene and antimony NPs exhibited stable electrochemical performances.…”

antimonene, representing for a single or few-layer antimony, has been considered as a unique one among other 2D materials due to its strong spin-orbit coupling and a number of extraordinary physical properties. [1,2] While the emergence of a new material brings both excitement and puzzles, until very recently, antimonene was successfully isolated by mechanical exfoliation [3] and liquid phase exfoliation, [4] which offers conditions for studying its applications in an experimental way. In addition, density functional theory (DFT) has allowed researchers to make a number of predictions about antimonene's structural and electronic properties, including puckered lamellar structure, [5] high carrier mobility, [6] large interlayer channel size, [3] and fast ion diffusion, [7] combined with the good electrical conductivity (1.6 × 10 4 S m −1 ) demonstrated by experimental test, [8] rendering antimonene an ideal candidate for electrochemical energy storage applications. As a result, there are several works addressing the utilization of antimonene as an anode material in batteries. [9][10][11] However, as for supercapacitor applications, the explorations are extremely scarce. Until now, only one work reported the basic characterization of antimonene as an electrochemically active material for capacitive energy storage (which demonstrated delightful results), [12] while further design and in-depth investigations of antimonene-based supercapacitor electrode, especially freestanding flexible electrode, are highly favorable.As for the constant evolution of freestanding flexible electrode, MXenes, a new burgeoning family of 2D transition metal carbides, offer a particularly suitable assembly platform due to their highly reversible surface redox reactions, [13] graphene-like flexibility and metallic electrical conductivity (up to 8000 S cm −1 ). [14] As a result, the multistacked MXene "paper" freestanding electrodes demonstrate excellent energy storage performances, which are on the topmost level among conventional freestanding electrodes based on graphene and carbon nanotube. [15,16] However, although breakthroughs were made by pristine MXene films, development of the energy storage performances of MXene-based flexible supercapacitors is still in its infancy.Advanced 2D materials have spurred great interest as a new paradigm in pursuing improved energy storage performance. Herein, for the first time, antimonene is utilized as an effective active component for constructing highly deformable and editable freestanding film electrodes, as the basis of a supercapacitor with record-breaking electrode performance. The insertion of antimonene is able to improve the environmental stability of the antimonene/ MXene composite electrode and remarkably enhance the energy storage capability in both protic and neutral electrolytes. Notably, an ultrahigh specific volumetric capacitance of 4255 F cm −3 is achieved by the electrode tested in a 1 m H 2 SO 4 electrolyte, which represents the state-of-the-art value reported to date for supercapa...

“…Recently, antimonene (Sb) possessing a buckled hexagonal structure has been successfully fabricated by mechanical exfoliation [10], van der Waals epitaxy on the PdTe 2 [11], as well as liquid-phase exfoliation [12]. Due to its low price, high theoretical capacity, moderate working voltage, and unique puckered-layer structure, antimonene has become an attractive choice as an anode material for high-performance LIBs and sodium-ion batteries (SIBs) [13,14,15,16]. The capacity of a few layers of antimonene for Li storage can be maintained at 584.1 mAhg −1 after 100 charging/discharging cycles, and the capacity fading during 100 cycles was only 3.8%, which is superior to those of Sb bulk and Sb nanoparticles [15].…”

To suppress the volume expansion and thus improve the performance of antimonene as a promising anode for lithium-ion batteries, we have systematically studied the stability, structural and electronic properties of the antimonene capped with graphene (G/Sb heterostructure) upon the intercalation and diffusion of Li atoms by first-principles calculations based on van der Waals (vdW) corrected density functional theory. G/Sb exhibits higher Young’s modulus (armchair: 145.20, zigzag: 144.36 N m−1) and improved electrical conductivity (bandgap of 0.03 eV) compared with those of antimonene. Li favors incorporating into the interlayer region of G/Sb rather than the outside surfaces of graphene and antimonene of G/Sb heterostructure, which is caused by the synergistic effect. The in-plane lattice constants of G/Sb heterostructure expand only around 4.5%, and the interlayer distance of G/Sb increases slightly (0.22 Å) at the case of fully lithiation, which indicates that the capping of graphene on antimonene can effectively suppress the volumetric expansion during the charging process. Additionally, the hybrid G/Sb heterostructure has little influence on the migration behaviors of Li on the outside of graphene and Sb surfaces compared with their free-standing monolayers. However, the migration energy barrier for Li diffusion in the interlayer region (about 0.59 eV) is significantly affected by the geometry structure, which can be reduced to 0.34 eV simply by increasing the interlayer distance. The higher theoretical specific capacity (369.03 mAh g−1 vs 208 mAh g−1 for antimonene monolayer) and suitable open circuit voltage (from 0.11 V to 0.89 V) of G/Sb heterostructure are beneficial for anode materials of lithium-ion batteries. The above results reveal that G/Sb heterostructure may be an ideal candidate of anode for high recycling–rate and portable lithium-ion batteries.
