“…4 d, including Sb–O–C, C=O, C–O, –OH, and –SO x bonds. The unusual peak at 530.9 eV further confirms the formation of Sb–O–C bonds in Sb/C interface [ 8 ]. As a profitable construction of interfacial chemical bond, Sb–O–C can be served as an amphibious bridge to enhance the fast transport of electron/ion as well as structure stability.…”

“…Nevertheless, the practical application of Sb 2 S 3 suffers from poor conductivity, weak structural stability, lower initial Coulombic efficiency (ICE), and “shuttling effect” of polysulfide [ 2 , 3 ]. In order to tackle these key problems, multifarious ways have been proposed, such as combining with highly conductive carbonaceous materials [ 4 , 5 ], designing greatly stable structures [ 6 , 7 ], building interfacial bonds [ 8 ], and introducing doping heteroatoms [ 9 ]. Constructing Sb 2 S 3 /carbon composite is the most common and effective strategy [ 10 – 12 ].…”

Highlights The chemical process of local oxidation–partial reduction–deep coupling for stibnite reduction of carbon dots (CDs) is revealed by in-situ high-temperature X-ray diffraction. Sb2S3@xCDs anode delivers high initial coulombic efficiency in lithium ion batteries (85.2%) and sodium ion batteries (82.9%), respectively. C–S bond influenced by oxygen-rich carbon matrix can restrain the conversion of sulfur to sulfite, well confirmed by X-ray photoelectron spectroscopy characterization of solid electrolyte interphase layers helped with density functional theory calculations. CDs-induced Sb–O–C bond is proved to effectively regulate the interfacial electronic structure. Abstract The application of Sb2S3 with marvelous theoretical capacity for alkali metal-ion batteries is seriously limited by its poor electrical conductivity and low initial coulombic efficiency (ICE). In this work, natural stibnite modified by carbon dots (Sb2S3@xCDs) is elaborately designed with high ICE. Greatly, chemical processes of local oxidation–partial reduction–deep coupling for stibnite reduction of CDs are clearly demonstrated, confirmed with in situ high-temperature X-ray diffraction. More impressively, the ICE for lithium-ion batteries (LIBs) is enhanced to 85%, through the effect of oxygen-rich carbon matrix on C–S bonds which inhibit the conversion of sulfur to sulfite, well supported by X-ray photoelectron spectroscopy characterization of solid electrolyte interphase layers helped with density functional theory calculations. Not than less, it is found that Sb–O–C bonds existed in the interface effectively promote the electronic conductivity and expedite ion transmission by reducing the bandgap and restraining the slip of the dislocation. As a result, the optimal sample delivers a tremendous reversible capacity of 660 mAh g−1 in LIBs at a high current rate of 5 A g−1. This work provides a new methodology for enhancing the electrochemical energy storage performance of metal sulfides, especially for improving the ICE.

“…According to the theoretical calculation, the metal nanoparticles composed of group IVA and VA elements, such as Co ( Yang et al, 2021a ), Sb ( Guan et al, 2019 ), Sn ( Jiang et al, 2019 ), Bi ( Wang et al, 2020a ), and the metal chalcogenide nanoparticles, such as Fe 2 O 3 ( Sultana et al, 2017 ), MoSSe ( Tian et al, 2020c ), and Sb 2 Se 3 ( Yang et al, 2022 ), have higher K + storage capacity than carbonaceous materials owing to their polymerous conversion and alloying reaction ( Yuan et al, 2021 ). Thus, the coupling of metal and chalcogenide nanoparticles can largely offset the weakness of the scarcity of K + storage sites and the poor wettability of the pristine carbon-based flexible electrode.…”

In recent years, carbon-based flexible anodes for potassium-ion batteries are increasingly investigated owing to the low reduction potential and abundant reserve of K and the simple preparation process of flexible electrodes. In this review, three main problems on pristine carbon-based flexible anodes are summarized: excessive volume change, repeated SEI growth, and low affinity with K+, which thus leads to severe capacity fade, sluggish K+ diffusion dynamics, and limited active sites. In this regard, the recent progress on the various modification strategies is introduced in detail, which are categorized as heteroatom-doping, coupling with metal and chalcogenide nanoparticles, and coupling with other carbonaceous materials. It is found that the doping of heteroatoms can bring the five enhancement effects of increasing active sites, improving electrical conductivity, expediting K+ diffusion, strengthening structural stability, and enlarging interlayer spacing. The coupling of metal and chalcogenide nanoparticles can largely offset the weakness of the scarcity of K+ storage sites and the poor wettability of pristine carbon-based flexible electrodes. The alloy nanoparticles consisting of the electrochemically active and inactive metals can concurrently gain a stable structure and high capacity in comparison to mono-metal nanoparticles. The coupling of the carbonaceous materials with different characteristics can coordinate the advantages of the nanostructure from graphite carbon, the defects and vacancies from amorphous carbon, and the independent structure from support carbon. Finally, the emerging challenges and opportunities for the development of carbon-based flexible anodes are presented.

Transition metal sulfides, due to excellent redox reversibility and considerable electronic conductivity, have been proposed as an available alternative material for rechargeable batteries. In this work, porous Zn0.76Co0.24S (ZCS) yolk‐shell microspheres are favorably obtained through a facile solvothermal manner, followed by a vulcanization process. The effects of vulcanization temperature on the morphology, structure, and electrochemical performance of the products are also explored. Owing to the unique buffering space and generous active sites of yolk‐shell structure, the electrode material exhibits excellent cycle and rate performance. Comparatively, Zn0.76Co0.24S vulcanized at 140 °C (ZCS‐140) retains a capacity of 671 mAh g−1 at 100 mA g−1 after 100 cycles and delivered a reversible capacity of 389 mAh g−1 at 1 A g−1 after 1000 cycles with a decay of only 0.029 % per cycle, which is better than that of ZCS‐120 and ZCS‐160, indicating its potential to be a promising next‐generation anode for SIBs.
