Kukankhira malire kachulukidwe mphamvu ya ma super-capacitor, kalasi yatsopano ya zida za elekitirodi yokhala ndi zomangamanga zabwino ndiyofunika kwambiri.
Binary metal sulfides amakhala ndi lonjezo lalikulu ngati ma elekitirodi pazida zosungiramo mphamvu zogwira ntchito kwambiri chifukwa amapereka ma elekitiromu apamwamba kwambiri komanso mphamvu zapamwamba kuposa ma mono-metal sulfides.
Apa, kapangidwe kabwino ndi kapangidwe ka ma nano-sheet a NiCo 2 S 4 omwe amathandizidwa ndi ma thovu a kaboni opangidwa ndi nayitrogeni (NCF) (ochokera ku thovu la melamine lopangidwa ndi kaboni la SINOYQX) akuwonetsedwa ngati electrode yatsopano yosinthasintha ya ma super-capacitors.
Njira yosavuta ya magawo awiri yapangidwa kuti ikule ma nanosheet a NiCo 2 S 4 pa NCF yokhala ndi kumatirira kolimba, komwe kumakhudza kukula kwa Ni-Co precursor ndikusinthidwa kukhala ma nanosheet a NiCo 2 S 4 kudzera mu njira ya sulfidation.
Popindula ndi mawonekedwe ake ophatikizika ndi mapangidwe a ma electrode a 3D, ma electrode a NiCo 2 S 4 /NCF ali ndi magwiridwe antchito abwino kwambiri a electrochemical okhala ndi capacitance yapamwamba kwambiri (877 F g −1 pa 20 A g −1 ) komanso kukhazikika kwabwino kwambiri pakuyenda kwa njinga.
Komanso, chipangizo chopanda ma binder asymmetric super-capacitor chimapangidwanso pogwiritsa ntchito NiCo 2 S 4 /NCF ngati electrode yabwino komanso ordered mesoporous carbon (OMC)/NCF ngati electrode yoyipa; izi zikuwonetsa kuchuluka kwa mphamvu (≈45.5 Wh kg −1 pa 512 W kg −1 ).
Kuti mudziwe zambiri za polojekitiyi, chonde musazengereze kulankhulana ndi SINOYQX kudzera pa: [email protected] kapena imelo pa [email protected] Laifa Shen, Jie Wang, Guiyin Xu, Hongsen Li, Hui Dou ndi Xiaogang Zhang ochokera ku College of Materials Science and Engineering Jiangsu Key Laboratory of Materials and Technologies for Energy Conversion, Nanjing, PR China Kuti muwonjezere mphamvu ya ma super-capacitors, gulu latsopano la zipangizo zama electrode zokhala ndi zomangamanga zabwino likufunika kwambiri.
