“…The XPS results reveal the existence of Sb 3+ in Sb 2 S 3 . [ 36 , 37 ] At the same time, it is noted that the peak at 533 eV can be designated to the oxygen absorbed on surface of Sb 2 S 3 . For the S 2p spectrum (Figure 2c ), peaks centered at 161.5 eV (S 2p 3/2 ) and 162.6 eV (S 2p 1/2 ) could be testified, which are corresponded to the signals of S 2− in Sb 2 S 3 .…”

Li metal is considered as one of the most promising candidates for constructing advanced high‐energy energy storage due to its ultrahigh theoretical capacity and lowest electrochemical potential. However, its practical commercialization is seriously hindered by the challenges of Li dendrite growth, low Coulombic efficiency, and huge volumetric variation. Herein, an efficient in situ generated Li2S‐rich interface layer joint with preplanted Sb nano active sites in hosted Li metal anode is easily achieved with the nanosized Sb2S3 decorated carbonaceous network. The yielded CC@Sb2S3@Li anode demonstrates uniform Li deposition, high Coulombic efficiency, and alleviated volumetric variation. Therefore, the Li symmetric cells show ultralong lifespan stable cycling over 3200 cycles with a very low voltage hysteresis (≈18 mV) at 5 mA cm−2. Impressively, the Li|LiFePO4 full cell delivers an exceptionally prolonged cycling over 180 cycles with a superior capacity retention as high as ≈90% even under the harsh condition of an extremely low negative to positive capacity ratio of ≈0.44 with lean electrolyte (4.4 µL mAh−1). Moreover, the Li|LiNi0.5Co0.2Mn0.3O2 full cell also maintains an excellent cycling performance under the more realistic harsh conditions. This work provides a new avenue and significant step paving the Li metal toward the practical application.

“…All the facts can confirm the hierarchical electrochemical reactions of the NSSCs anode, which are in accord with the reported Sb2S3 anode materials. 21,22,43 The total discharge-charge process of the NSSCs anode are stated using the following equations: High cycle performance is a critical factor for battery-operated applications. The NSSCs anode shows unchanging cycle performances at 0.2 A g -1 with a good initial discharge capacity of 1110 mA h g -1 and a finished capacity of 606.3 mA h g -1 after 150 cycles (Figure 3d).…”

Antimony trisulfide (Sb2S3) is a prospective electrode material for lithium-ion batteries (LIBs) because of its thermal stability, low price and high specific capacity.However, the commercialization of the Sb2S3 as an anode material is greatly hindered by its poor electronic conductivity and massive volume variation during charge/discharge cycles. Moreover, growing demand in reducing greenhouse gas emissions requires the materials preparation process to be pollution-free and high energy-efficient. Herein, we introduce, for the first time, an eco-friendly and highly efficient one-step annealing method to construct a 3D flexible conductive network and buffer matrix for N-doped Sb2S3-carbon fibers (NSSCs) as a high-performance anode.

In charge‐discharge cycles, carbon shell or carbon skeleton type structures precisely confine the volume change of active materials particles while the mesopores and conductive walls provide efficient mass transport and fast charge transfer routes.…”

To meet the high‐speed commercialization demands of electrochemical energy storage and conversion devices, the development of high‐performance and low‐cost electrode materials is urgently necessary. Mesoporous carbon, which shows excellent intrinsic characteristics and flexible structure, has raised a surge of interest recently since it offers opportunities for improving the energy or power density and durability as well as reducing the cost of electrodes. In this paper, we first review primary methods for preparing mesoporous carbons. Next, the obstacles in lithium batteries, supercapacitors, proton exchange membrane fuel cells and water electrolyzers are analyzed and the recent progresses of mesoporous carbon based electrode designs in solving these obstacles are systematically introduced. Finally, we outline current challenges and future directions of developing mesoporous carbon based electrode materials in electrochemical energy storage and conversion devices. In creating this review, we hope to give a succinct introduction to the mesoporous carbon and provide meaningful references for its future research.
