“…[22][23][24][25][26][27] These NiCo 2 S 4 nanostructures, such as spheres and wires, have all exhibited good bifunctional OER and ORR activity, 5,6,8,9,12,[28][29][30] which may be further enhanced by improving electron transfer via the engineering of surface morphology, incorporating highly conductive support materials, and doping with selected tertiary atoms. 5,[31][32][33][34][35][36][37] Previous studies show that NiCo 2 S 4 possesses a mixedvalence redox chemistry. 5,12,18 However, it remains largely not understood how individual cobalt and nickel cations affect the electrocatalytic performance of NiCo 2 S 4 .…”

“…For one aspect, we can change the molar ratio of Ni to Co, for example, CoNi2S4, [50,[70][71][72] Ni3-xCoxS4. [73][74][75] For another aspect, the element in A and B position can be changed to other transition metals, such as MnCo2S4, [76,77] CuCo2S4, [78,79] FeNi2S4. [80] Through such modification, the electrochemical performance of the NiCo2S4 related materials can be tuned.…”

NiCo2S4 has attracted worldwide attention in the field of energy storage/conversion. In this paper, we summarize the up-to-date progress on the preparation strategies, the applications as electrode materials for supercapacitors, lithium-ion batteries and dye sensitized solar cells, as well as electrocatalysts for the hydrogen evolution reaction, oxygen reduction reaction and oxygen evolution reaction. We also discuss the strategies to improve the electrochemical performance, and future trends of the NiCo2S4-based materials.

“…[1][2][3][4][5][6] It is imperative to develop more excellent electrode materials for application in LIBs to meet the demand of high powere lectricale quipment. [7,8] Metal sulfides have drawn significant attention as anode materials for LIBs, because they can exhibit much higher theoretical capacities (e.g.,S nS:1 136 mA hg À1 )t han that of commercialg raphite (372 mA hg À1 ). [9,10] Moreover, metal sulfides display highere lectronic conductivities (approximately 10 À3 Scm À1 )t han those of metal oxides, which can avoid capacity fading that results from poor electronic conductivity.…”

Porous core–shell CuCo2S4 nanospheres that exhibit a large specific surface area, sufficient inner space, and a nanoporous shell were synthesized through a facile solvothermal method. The diameter of the core–shell CuCo2S4 nanospheres is approximately 800 nm„ the radius of the core is about 265 nm and the thickness of the shell are approximately 45 nm, respectively. On the basis of the experimental results, the formation mechanism of the core–shell structure is also discussed. These CuCo2S4 nanospheres show excellent Li storage performance when used as anode material for lithium‐ion batteries. This material delivers high reversible capacity of 773.7 mA h g−1 after 1000 cycles at a current density of 1 A g−1 and displays a stable capacity of 358.4 mA h g−1 after 1000 cycles even at a higher current density of 10 A g−1. The excellent Li storage performance, in terms of high reversible capacity, cycling performance, and rate capability, can be attributed to the synergistic effects of both the core and shell during Li+ ion insertion/extraction processes.
