“…1D single crystal WO 3 nanowires fabricated by Gu et al delivered a discharge capacity of 218 mAh g −1 for the first cycle under a current of 50 mA g −1 , and a capacity retention of 75.2% after 50 cycles, which can be largely attributed to the robust structural stability given by the 1D structure (Gu et al, 2007;Huang et al, 2020;Li et al, 2020). On the other hand, hierarchical structures have demonstrated their favorable Li-ion storage properties (Zhao et al, 2019;Liang et al, 2022). ) mesocrystals by an ionic liquid-assisted hydrothermal route; the specific capacity of h-WO 3 mesocrystals can be maintained at 426 mAh g −1 at 50 mA g −1 after 50 cycles, benefiting from its inherent uniform porosity associated with well-defined nanoparticle orientation (Duan et al, 2015;Liu C. et al, 2020).…”

The pursuit of electrochemical energy storage has led to a pressing need on materials with high capacities and energy densities; however, further progress is plagued by the restrictive capacity (372 mAh g−1) of conventional graphite materials. Tungsten trioxide (WO3)-based anodes feature high theoretical capacity (693 mAh g−1), suitable potential, and affordable cost, arousing ever-increasing attention and intense efforts. Nonetheless, developing high-performance WO3 electrodes that accommodate lithium ions remains a daunting challenge on account of sluggish kinetics characteristics and large volume strain. Herein, the well-designed hierarchical WO3 agglomerates assembled with straight and parallel aligned nanoribbons are fabricated and evaluated as an anode of lithium-ion batteries (LIBs), which exhibits an ultra-high capacity and excellent rate capability. At a current density of 1,000 mA g−1, a reversible capacity as high as 522.7 mAh g−1 can be maintained after 800 cycles, corresponding to a high capacity retention of ∼80%, demonstrating an exceptional long-durability cyclic performance. Furthermore, the mechanistic studies on the lithium storage processes of WO3 are probed, providing a foundation for further optimizations and rational designs. These results indicate that the well-designed hierarchical WO3 agglomerates display great potential for applications in the field of high-performance LIBs.

“…Lithium-ion batteries (LIBs) have been wildly used in small consumer electronics, electric vehicles, and medical apparatus as energy storage devices due to their advantages of high energy density, long cycle life, high working voltage, no memory effect, small self-discharge, and wide operating temperature range ( Sun et al, 2010 ; Wang et al, 2020c ; Gu et al, 2021 ; Li et al, 2021a ; Li et al, 2021b ; Li et al, 2021c ; Li et al, 2021d ; Zhao et al, 2021 ; Liang et al, 2022 ). However, to apply in large-scale energy storage projects and other high-power systems, the electrochemical properties of power density, rate capacity, cycle stability, and safety issue should be further improved ( Sun et al, 2011 ; Zhang et al, 2019b ; Wang et al, 2020b ; Zhang et al, 2020a ; Wang et al, 2021b ).…”

In order to solve the poor cycle stability and the pulverization of cobalt sulfides electrodes, a series of amorphous and crystalline cobalt sulfides were prepared by one-pot solvothermal synthesis through controlling the reaction temperatures. Compared to the crystalline cobalt sulfide electrodes, the amorphous cobalt sulfide electrodes exhibited superior electrochemical performance. The high initial discharge and charge capacities of 2,132 mAh/g and 1,443 mAh/g at 200 mA/g were obtained. The reversible capacity was 1,245 mAh/g after 200 cycles, which is much higher than the theoretical capacity. The specific capability was 815 mAh/g at 800 mA/g and increased to 1,047 mAh/g when back to 100 mA/g, indicating the excellent rate capability. The outstanding electrochemical performance of the amorphous cobalt sulfide electrodes could result from the unique characteristics of more defects, isotropic nature, and the absence of grain boundaries for amorphous nanostructures, indicating the potential application of amorphous cobalt sulfide as anodes for lithium-ion batteries.

“…Nanomaterials have shown excellent physical and chemical properties in many fields due to their larger specific surface area and higher activity (Wang et al, 2014;Wang et al, 2017;Li H. et al, 2019;Zhou et al, 2019;Gu et al, 2021;Zhao et al, 2021;Liang et al, 2022;Wang et al, 2022). Transition metal sulfide (TMS) nanomaterials have been extensively researched in the field of the anode materials of LIBs due to low redox potential, good conductivity, strong cycling stability, and high theoretical capacity (Zhao et al, 2018;Wang et al, 2020;Yang et al, 2021).…”

Nickel sulfide has been widely studied as an anode material for lithium-ion batteries due to its environmental friendliness, low cost, high conductivity, and high theoretical capacity. A simple hydrothermal method was used to prepare NiS nanospheres materials with the size in the range of 100–500 nm. The NiS nanospheres electrodes exhibited a high reversible capacity of 1402.3 mAh g−1 at 200 mA g−1 after 280 cycles and a strong rate capability of 814.8 mAh g−1 at 0.8 A g−1 and 1130.5 mAh g−1 when back to 0.1 A g−1. Excellent electrochemical properties and the simple preparation method of the NiS nanospheres make it possible to prepare NiS on a large scale as the anode of lithium-ion batteries.
