Multidimensional antimony nanomaterials tailored by electrochemical engineering for advanced sodium-ion and potassium-ion batteries

Recent advances in Sb-based anodes for Li/Na/K-ion batteries and all-solid-state Li-ion batteries

“…Nanostructural design and low-dimensional engineering aimed at accelerating reaction kinetics are considered the most efficient strategies for addressing the abovementioned drawbacks, including the sluggish rate capability and rapid capacity decay associated with the excessive volume change experienced by Sb [67,[91][92][93][94][95][96] . Liu et al fabricated highly uniform Sb nanotubes (NTs) using a galvanic replacement approach using a Cu 2 Sb-mediated formation mechanism [91] .…”

“…Furthermore, empty carbon boxes with rich hierarchical pores and high conductivities exhibited excellent rate performance by promoting fast Na-ion/ electron transfer. Li et al synthesized various multidimensional Sb nanostructures as SIB anode materials using a chemical dealloying approach [95] . The 0D Sb nanoparticles (Sb-NPs), 2D Sb nanosheets (Sb-NSs), and 3D nanoporous (NP) Sb were synthesized by modifying the dealloying reaction kinetics using different etching solvents.…”

State-of-art progress and perspectives on alloy-type anode materials for potassium-ion batteries

“…Therefore, the rational design of the structure of Sb-based electrodes to maintain their long-term stability is vital to improve the K storage performance. 110 To date, several practical strategies have been proposed to overcome this issue.…”

“…13(b)). Recently, Yang et al 110 successfully prepared a 0D, 2D (antimonene nanosheets) and 3D porous Sb network via electrochemical delamination of bulk Sb in different organic solution and found that the 2D antimonene nanosheets exhibited an outstanding K + storage performance of a high specific capacity of 550.3 mA h g −1 after 300 cycles at a current density of 200 mA g −1 . These results demonstrate that suitable design of the Sb structure is very important for Sb in high-performance PIBs.…”

Chemical Scissor-Enabled synthesis of Ti3C2Tx MXene nanowires for selective oxygen reduction to hydrogen peroxide

“…MXene is usually obtained by selectively etching A layer from Mn+1AXn, where M is an early transition metal, A is an element of group IIIa or IVa (mainly Al or Si), X is C and/or N, and n=1, 2 or 3 [3,4]. As a typical MXene, accordion-like Ti3C2 can be obtained by etching Ti3AlC2 with HF or LiF/HCl, and further exfoliated to Ti3C2Tx nanosheets through intercalation and ultrasonication, where T stands for termination groups (-H, -F, -O or -OH) and x indicates uncertain amount of surface groups [5,6].…”
