Hei turaki i te rohe kiato o te kaha o nga punga-nui, me tino hiahia tetahi karaehe hou o nga rawa hiko me nga hoahoanga pai.
Ko nga sulfide whakarewa-rua e mau ana i te oati nui hei taonga hiko mo nga taputapu rokiroki hiko mahi nui na te mea he nui ake te mahi hiko me te kaha teitei ake i te sulfide whakarewa-mono.
I konei, ka whakaatuhia te hoahoa whaitake me te hanga o ngā rau-nano NiCo 2 S 4 e tautokona ana i runga i ngā pahuka waro kua tāpirihia ki te hauota (NCF) (i runga i te pahuka melamine kua whakakīia ki te waro SINOYQX) hei hiko ngāwari hou mō ngā super-capacitors.
Kua whakawhanakehia he tikanga ngāwari, e rua ngā taahiraa, mō te whakatipu i ngā nanosheets NiCo 2 S 4 ki runga i te NCF me te piri pakari, e uru ana ki te whakatipu i te Ni-Co precursor me te hurihanga i muri mai hei nanosheets NiCo 2 S 4 mā te tukanga sulfidation.
I runga i ngā āhuatanga hanganga me ngā hoahoanga hiko 3D, ka whakaatuhia e te hiko NiCo 2 S 4 /NCF te mahi hiko matū kua tino pai ake me te kaha tino teitei (877 F g −1 i te 20 A g −1 ) me te pumau huringa tino pai.
Hei tāpiritanga, ka hangaia hoki he taputapu super-capacitor kore-here mā te whakamahi i te NiCo 2 S 4 /NCF hei irahiko pai me te waro mesoporous kua whakaritea (OMC) /NCF hei irahiko kino; e whakaatu ana tēnei i te kiato pūngao teitei (≈45.5 Wh kg −1 i te 512 W kg −1 ).
Mō ētahi atu pārongo e pā ana ki te kaupapa, tēnā whakapā atu ki a SINOYQX mā te: [email protected] īmēra rānei ki [email protected] Laifa Shen, Jie Wang, Guiyin Xu, Hongsen Li, Hui Dou me Xiaogang Zhang o te Kāreti Pūtaiao Rauemi me te Hangarau Jiangsu Key Laboratory of Materials and Technologies for Energy Conversion, Nanjing, PR China Hei pana i te rohe kiato pūngao o ngā super-capacitors, me tino hiahiatia he akomanga hou o ngā rauemi hiko me ngā hoahoanga pai.
