“…The assembled ASC device exhibits a significant energy density of 33.05 Wh kg –1 at a quite high power density (1.68 kW kg –1 ) and remains 20.52 Wh kg –1 even at a very high power density (8.29 kW kg –1 ). The excellent all‐solid‐state storage performance can be compared with the reported nickel sulfide‐based ASC, including rose‐like Ni 3 S 4 (18.625 Wh kg –1 at 1.5 kW kg –1 ) [ 25 ] , NiS/Ni 3 S 4 (37.3 Wh kg –1 at 398 W kg –1 ), [ 26 ] NC/Ni−Ni 3 S 4 / CNTs (39.8 Wh kg –1 at 749.8 W kg –1 ), [ 27 ] MoS 2 /NiS (31 Wh kg –1 at 155.7 W kg –1 ), [ 28 ] NiO/NiS@CNT (29.87 Wh kg –1 at 0.8 kW kg –1 ), [ 29 ] NiS‐CFs (13.8 Wh kg –1 at 373.9 W kg –1 ), [ 30 ] NiS (24.4 Wh kg –1 at 767 W kg –1 ), [ 31 ] NiS@C (21.6 Wh kg –1 at 400 W kg –1 ), [ 32 ] as presented in Figure 4f. To validate the practicability of the ASC commercial applications, the LED bulb can be lightened (Figure 4h) by connecting three fully charged devices in series.…”

“…[21] Different GObased nano composites have been developed with excellent photo-electro-chemical performance. [3,[22][23][24][25] Among all the composites identified, GO-nano NiS composites have been reported as electrode materials in lithium ion batteries, [26][27][28] supercapacitors, [29][30][31] dye-sensitized solar cells, [32][33][34] chemical sensors, [35,36] and so on. They all expressed superior photoelectro-chemical performances and potential application prospects, by virtue of the excellent synergistic-enhancement effect among GO substrate and various functional nano particles.…”

“…For instance, on the basis of the crystal growth principle, introducing nucleating species, such as Ni foam, Cu foam, carbon cloth, graphene, graphene oxide, and N-doping graphene into the solution to induce M m + or A n − to adsorb on their surface for in situ growth can effectively control the growth process of [M x m + / m ] x + [A x n − / n ] x − , forming a large number of [M x m + / m ] x + [A x n − / n ] x − with different morphologies such as layer-shaped structures, core–shell structures, and heterojunctions. 18–20 In a homogeneous reaction system, introducing additives such as ammonia, urea, ligand, and anion ( e.g. , OH − , CO 3 2− ) to adjust the chemical environment of M m + or control the formation rate of A n − also easily changes the morphology of products.…”
