“…As shown in Figure 7F , the capacitive capacity makes up about 29% of the total capacity at the scan rate of 0.1 mV s −1 , whereas this value increases to 56% and 64% at the scan rate of 1 and 2 mV s −1 , respectively. Similar results have also been reported for the nano-sized NiO and Ni(OH) 2 anode materials (Li Y. W. et al, 2017b ; Zheng Y. Y. et al, 2018 ). This significant surface or near surface charge storage due to capacitive behavior benefits the high rate capability and cycling stability of electrode active materials (Rauda et al, 2013 ; Augustyn et al, 2014 ; Li Y. W. et al, 2017a ).…”

Recycling Zn and Fe from jarosite residue to produce high value-added products is of great importance to the healthy and sustainable development of zinc industry. In this work, we reported the preparation of ZnFe2O4/α-Fe2O3 nanocomposites from the leaching liquor of jarosite residue by a facile chemical coprecipitation method followed by heat treatment at 800°C in air. The microstructure of the as-prepared ZnFe2O4/α-Fe2O3 nanocomposites were characterized by X-ray diffraction (XRD), Mössbauer spectroscopy, scanning transmission electron microscope (STEM), and X-ray photoelectron spectrum (XPS). The results demonstrated that the ZnFe2O4/α-Fe2O3 composites are composed of interconnected ZnFe2O4 and α-Fe2O3 nanocrystals with sizes in the range of 20–40 nm. When evaluated as anode material for Li-ion batteries, the ZnFe2O4/α-Fe2O3 nanocomposites exhibits high lithium storage activity, superior cyclic stability, and good high rate capability. Cyclic voltammetry analysis reveals that surface pseudocapacitive lithium storage has a significant contribution to the total stored charge of the ZnFe2O4/α-Fe2O3, which accounts for the enhanced lithium storage performance during cycling. The synthesis of ZnFe2O4/α-Fe2O3 nanocomposites from the leaching liquor of jarosite residue and its successful application in lithium-ion batteries open up new avenues in the fields of healthy and sustainable development of industries.

“…When the current changes back to 1 A g −1 , the capacity retains 715 mA h g −1 . The performances of the electrode outperformed most reported NiO‐based electrodes, including mesoporous NiO nanosheet, porous NiO nanorod, NACNT@NiO@G, porous NiO microtubules, NiO/CNTs, and C@NiO@NCSs electrodes, as shown in Figure E and Table S1. Moreover, the long cycle stability of the electrode at a higher 10 A g −1 is displayed in Figure F.…”

Transition metal oxides hold great promise for lithium‐ion batteries (LIBs) and electrocatalytic water splitting because of their high abundance and high energy density. However, designing and fabrication of efficient, stable, high power density electrode materials are challenging. Herein, we report rambutan‐like hollow carbon spheres formed by carbon nanosheet decorated with nickel oxide (NiO) rich in metal vacancies (denoted as h‐NiO/C) as a bifunctional electrode material for LIBs and electrocatalytic oxygen evolution reaction (OER). When being used as the anode of LIBs, the h‐NiO/C electrode shows a large initial capacity of 885 mA h g−1, a robust stability with a high capacity of 817 mA h g−1 after 400 cycles, and great rate capability with a high reversible capacity of 523 mA h g−1 at 10 A g−1 after 600 cycles. Moreover, working as an OER electrocatalyst, the h‐NiO/C electrode shows a small overpotential of 260 mV at 10 mA cm−2, a Tafel slope of 37.6 mV dec−1 along with good stability. Our work offers a cost‐effective method for the fabrication of efficient electrode for LIBs and OER.

“…TMC materials possess high theoretical lithium-storage capacity (~670 mAh g −1 with MoS 2 and 433 mAh g −1 with WS 2 ). However, the practical showed that a high abnormal capacity was recorded, which can contribute by conversion reaction, the derived solid electrolyte interface (SEI)-layer formation, or the high lithiation process in the interfacial lithium-storage spaces [ 19 , 20 , 21 ]. For example, Feng et al fabricated WS 2 nanoflakes for lithium-ion batteries (LIBs), which delivered a high initial discharge capacity of ~ 1700 mAh g −1 at a current of 47.5 mA g −1 [ 22 ].…”

The combination of W2C and WS2 has emerged as a promising anode material for lithium-ion batteries. W2C possesses high conductivity but the W2C/WS2-alloy nanoflowers show unstable performance because of the lack of contact with the leaves of the nanoflower. In this study, carbon nanotubes (CNTs) were employed as conductive networks for in situ growth of W2C/WS2 alloys. The analysis of X-ray diffraction patterns and scanning/transmission electron microscopy showed that the presence of CNTs affected the growth of the alloys, encouraging the formation of a stacking layer with a lattice spacing of ~7.2 Å. Therefore, this self-adjustment in the structure facilitated the insertion/desertion of lithium ions into the active materials. The bare W2C/WS2-alloy anode showed inferior performance, with a capacity retention of ~300 mAh g−1 after 100 cycles. In contrast, the WCNT01 anode delivered a highly stable capacity of ~650 mAh g−1 after 100 cycles. The calculation based on impedance spectra suggested that the presence of CNTs improved the lithium-ion diffusion coefficient to 50 times that of bare nanoflowers. These results suggest the effectiveness of small quantities of CNTs on the in situ growth of sulfides/carbide alloys: CNTs create networks for the insertion/desertion of lithium ions and improve the cyclic performance of metal-sulfide-based lithium-ion batteries.
