“…It is notable that a couple of typically reversible redox peaks with an outstanding symmetrical profile can be distinctly detected, reflecting the faradaic characteristics of battery-type electrodes and the excellent reversibility of the r-Ni 3 S 2 NSs. The detailed mechanism during the electrochemical reaction refers to the faradaic redox process of Ni(II)/Ni(III) based on the following equation: − Ni 3 S 2 + 3OH – → Ni 3 S 2 (OH) 3 + 3e – . All CV curves display a similar shape, while r-Ni 3 S 2 NSs possess a substantially increased integration area and peak current response than those of Ni 3 S 2 NSs, revealing the primarily enhanced capacity.…”

The development of an efficient metal sulfide cathode is of great importance and an ongoing challenge for the practical application of an aqueous rechargeable Ni-Zn battery. Herein, Ni 3 S 2 nanosheets with abundant sulfur vacancies (r-Ni 3 S 2 ) have been successfully prepared via hydrothermal reaction and surface engineering, which are further employed as the binder-free cathode of the aqueous Ni-Zn battery. Benefitting from the features of substantially improved electrical conductivity, low band gap, abundant active sites, and good intrinsic capacity, the r-Ni 3 S 2 electrode delivers an impressive reversible specific capacitance (1621.6 F g −1 at 0.2 A g −1 ) and extraordinary rate capability (62.1% retention under 8 A g −1 ). Moreover, the aqueous rechargeable r-Ni 3 S 2 //Zn battery exhibits a remarkable specific capacity (240.8 mAh g −1 at 1 A g −1 ) and preeminent cycling durability (only 8.4% decay after 3000 cycles). Besides, a glorious energy density of 419.6 Wh kg −1 together with a peak power density of 1.84 kW kg −1 could be achieved, surpassing a significant percentage of the reported Ni-Zn batteries. The results reveal that the r-Ni 3 S 2 cathode with abundant sulfur vacancies and the adopted facile approach possesses huge promotion potential for Ni-Zn batteries and is promising to numerous electronics and electric vehicle applications in the future.

SCs suitable for many different occasions. [1][2][3][4][5][6][7] However, the low energy density limits their extensive commercial applications. Based on the above, hybrid supercapacitors (HSCs) also called supercapattery with battery-type positive electrode as the energy source and electric double-layer capacitor negative electrode as the power source have been designed, it combines the dual advantages of high power density of traditional SCs and high energy density of batteries. [7][8][9][10] Further, the electrochemical properties of the HSCs are mainly determined by the battery-type electrode, so selecting suitable electrode materials or optimizing the electrode structure is essential for obtaining high-performance hybrid devices.Transition metal oxides and sulfides have become the most widely studied battery-type electrodes due to their remarkable electrochemical activity and high specific capacity. [11][12][13] For example, Chen et al. reported the self-supported Ni 3 S 2 nanosheet arrays by a two-step method. Benefiting from its unique 3D sheet structure, the electrode shows superb rate capability and energy density. [14] Kim et al. designed the independent electrode of NiMo 2 S 4 using the successive ionic layer adsorption and reaction (SILAR) method, which also showed high reversible specific capacity. [15] Although some progress has been made in the research of battery-type electrodes, the inherent physical and chemical properties of the single electrode materials may limit the further development. In order to achieve higher electrochemical performance, complex and stable electrode structures are required to be constructed.In the previous work, the first-principles calculations show that amorphous oxides (such as MnO 2 , [16] ) can produce lots of unsaturated suspension bonds, which makes them have a broad application prospect in the field of energy storage. [18][19][20] Liu et al. proposed amorphous manganese oxide as the pseudocapacitive electrode, which proved to possess excellent rate capability and high cycle stability. [21] This may be due to the fact that the loose arrangement of atoms and ions is more conducive to rapid ion transport of the active materials in the bulk of oxides. Sun et al. successfully synthesized MoO 3 by electrochemical deposition technique and pointed out that the disordered structure is likely to release the structural stress caused by the repeated ion deintercalation/intercalation behavior, thus Hybrid supercapacitors (HSCs), also called supercapattery, which can substitute for low power density batteries have attracted extensive interest. However, when HSCs comes to commercial applications, there is still space for improvement in energy density. It seems that designing of electrode with high capacity is an effective measure. Herein, amorphous-crystalline MoO 3 -Ni 3 S 2 /NF-0.5 nanosheet arrays are developed as battery-type electrodes. Specifically, the sheet-like structure of crystalline Ni 3 S 2 can achieve rich structural nanocrystallization, improving the redox reacti...

The rational design of a multicomponent electrode material with hollow structures grown on the conductive substrate is an effective approach to boost the electrochemical performance of supercapacitors (SCs). However, there is still a challenge in the in situ construction of such unique structures on the conductive substrate. Herein, a heterostructured multicomponent electrode material, a Zn−Mo−Ni−O−S hollow microflower (Zn−Mo−Ni−O−S HMF) in situ grown on a Ni foam (NF), is fabricated by a simple top-down strategy. Based on the ion-exchange and Kirkendall effect, the microflowers are composed of numerous hollow nanosheets, which are covered by uniform ZnS nanoparticles with a robust adherence. Profiting from the structural merits and the synergistic effect of multiple components, the Zn−Mo−Ni−O−S HMF electrode exhibits a high areal capacitance of 4.39 C cm −2 (6.27 F cm −2 ) at 1 mA cm −2 , which is 3.6 times higher than the 0.86 C cm −2 (1.72 F cm −2 ) of the Zn−Mo−O precursor and 1.7 times higher than the 2.65 C cm −2 (3.79 F cm −2 ) of Ni 3 S 2 /NiMoO 4 (Mo−Ni−O−S). The Zn−Mo−Ni−O−S HMF displays an excellent cycling performance (maintaining 87.9% after 3000 cycles). The hybrid supercapacitor device is assembled by the Zn−Mo−Ni−O−S HMF as the positive electrode and active carbon (AC) as the negative electrode. The device delivers a high energy density of 60.8 Wh kg −1 at a power density of 750.2 W kg −1 . The synthetic route provides a reference to the in situ construction of a heterostructured multicomponent electrode material for high-energy SCs.
