“…This result, together with the XRD, confirms that NF‐S1 is mainly composed of β‐Ni(OH) 2 . For NF‐S2 and NF‐S3, the Raman spectra showed peaks at 188, 202, 225, 300 and 350 cm −1 , which are characteristic Raman peaks of Ni 3 S 2 . Although Ni(OH) 2 peaks at 310 and 445 cm −1 were also found in these samples, the presence of Ni(OH) 2 in NF‐S2 and NF‐S3 should be in trace amount based on the XRD results.…”

Hierarchicaln anostructures grown on conductive 3D scaffold materials are excellent candidates for supercapacitor electrodes. Herein, we report the fabrication and electrochemical performance of 3D Ni 3 S 2 nanoporous structures directly grown on nickel foam via af acile and cost-effective one-step process using Ni foam as both the template and Ni source. An ultrahigha real capacitance of 7.25 Fcm À2 was obtained at ac urrent density of 5mAcm À2 for the nanoporous Ni 3 S 2 structures. The encouraging performance of Ni 3 S 2 nanoporous structures allowed for the fabrication of asymmetrics upercapacitors (ASCs) using Ni 3 S 2 as cathode and activated carbon as anode. The resulting ASC exhibited high volumetric capacitance (4.48 Fcm À3 at 6mAcm À2 ), high energy density (1.54 mWh cm À3 at ap ower density of 0.07 Wcm À3 ), and excellent cycling stability (92.7 %r etention of the initial capacitance after 5000 cycles at ac urrent density of 16 mA cm À2 ).Recently,t ransition metal sulfides (CuS x ,C oS x and NiS x )h ave received intensive interesta ss upercapacitora ctivem aterials since they have excellent intrinsic chemical and physicalp roperties (higher electrical conductivity,a nd mechanical and thermal stability than their corresponding metal oxides) and good electrochemical performance. [4] Nickels ulfides, which can exist as NiS, NiS 2 ,N i 3 S 2 ,N i 6 S 5 ,N i 7 S 6 and Ni 3 S 4 phases, constitute ac onsiderable portion of transition metal sulfides and have been widely investigated due to av arietyo fp otential applications, such as supercapacitors, photovoltaic cells, rechargeable batteries and photocatalysts. [5] Among all nickel sulfides, Ni 3 S 2 is particularly of interest. It is an abundant and cheap material because it exists as heazlewoodite mineral in nature and possessesh igh theoretical capacity and good conductivity.N i 3 S 2 with variousm orphologies including nanoparticles, nanorods, nanosheets, dendrites and hollow nanospheresh ave been synthesized to date and these nanostructures have been reported to display high capacitive performance in supercapacitor application. [6] For example, Zhang et al. synthesized bacteria reduced graphene oxide/nickels ulfide networks on nickel foam (NF). [7] The networks exhibitedaspecificc apacitance of 1424 Fg À1 at 0.75 Ag À1 ,a nd 67.5 %o ft he capacitance was retained when the currentw as increased from 0.75 to 15 Ag À1 . Zhang and coworkers reportedh ydrothermals ynthesis of Ni 3 S 2 /graphene nanosheets on NF and employed the nanocomposite as as upercapacitore lectrode material. The electrode exhibited 1420 Fg À1 at 2Ag À1 with ah ighc ycle life. [8] Most recently,N i 3 S 2 nanoparticles were grown on graphene coatedN Ft hrough hydrothermal method and displayedaspecific capacitance of 3296 Fg À1 . [9] However,t he electrode could only retain 74 %o fi ts initial capacitance after 1000 cycles and the graphene coating process requires at emperature as high as 1000 8C. Similarly,Z hou et al. synthesized Ni 3 S 2 ,[a] G.Supporting information and the ORCID ...

“…[29] Among numerous pseudocapacitive materials used as electrode for supercapacitors, Ni 3 S 2 , presenting various morphologies and nanostructures, has become the most investigated one recently, because of its low cost, high specific capacitance and easy synthesis. [30][31][32][33][34] [37] as well as the environmentally friendly hydrothermal synthesis of nickel sulfide nanospheres. [38] Therefore, if 3D hierarchical nanosturtures were designed successfully and applied as supercapacitor electrode, it would exhibit a considerable increase of the active material availability for electrochemical performance.…”

“…9,[12][13][14][15] In addition, doping carbonaceous materials with exotic elements such as sulfur and nitrogen can also enhance the lithium storage performance, but still with limitations. [16][17][18][19] Recently, nickel suldes (e.g., NiS, NiS 2 , Ni 3 S 2 , and Ni 9 S 8 ) have been proposed as alternative anodes in LIBs owing to their high capacities achieved via a conversion mechanism. 15,17,[20][21][22] Among them, Ni 3 S 2 , one of the most important phases of nickel sulde, is abundant in nature and cheap and has been reported to exhibit unique properties for electrochemical energy storage and conversion in recent years.…”
