Kusundidzira iyo simba density muganho we-super-capacitor, kirasi nyowani yemagetsi emagetsi ane yakanaka ekuvaka inodiwa zvakanyanya.
Binary metal sulfides inobata chivimbiso chikuru sechigadzirwa che electrode chepamusoro-chinoita simba rekuchengetedza simba nokuti inopa yakakwirira electrochemical chiitiko uye yakakwirira yepamusoro kupfuura mono-metal sulfides.
Pano, dhizaini ine musoro uye kugadzirwa kweNiCo 2 S 4 nano-sheets dzakatsigirwa nenitrogen-doped carbon foams (NCF) (yakavakirwa paSINOYQX carbonized melamine foam) inoratidzwa seelectrode itsva inochinjika ye super-capacitors.
Nzira iri nyore ine matanho maviri yakagadzirwa yekukura kwema nanosheets eNiCo 2 S 4 paNCF ane kunamatira kwakasimba, zvichisanganisira kukura kweNi-Co precursor uye kushandurwa kuita ma nanosheets eNiCo 2 S 4 kuburikidza nekuita sulfidation.
Ichibatsirwa nemabasa ayo ekuumba uye magadzirirwo emagetsi e3D, electrode yeNiCo 2 S 4 /NCF inoratidza kushanda kwayo kwemagetsi kwakawedzera zvikuru ine capacitance yepamusoro-soro (877 F g −1 pa20 A g −1 ) uye kugadzikana kwakanaka kwekufamba kwemhepo.
Uyezve, mudziyo we super-capacitor usina binder unogadzirwawo uchishandisa NiCo 2 S 4 /NCF se positive electrode uye wakarongwa mesoporous carbon (OMC)/NCF se negative electrode; izvi zvinoratidza simba rakawanda (≈45.5 Wh kg −1 pa512 W kg −1 ).
Kuti uwane rumwe ruzivo nezve projekiti iyi, ndapota inzwa wakasununguka kubata SINOYQX kuburikidza ne: [email protected] kana kutumira email pa [email protected] Laifa Shen, Jie Wang, Guiyin Xu, Hongsen Li, Hui Dou naXiaogang Zhang vanobva kuCollege of Materials Science and Engineering Jiangsu Key Laboratory of Materials and Technologies for Energy Conversion, Nanjing, PR China Kuti tiwedzere simba remagetsi re super-capacitors, kirasi itsva yezvinhu zve electrode zvine magadzirirwo akanaka inodiwa zvikuru.
