Txhawm rau thawb lub zog ceev txwv ntawm super-capacitors, chav kawm tshiab ntawm cov khoom siv hluav taws xob nrog cov qauv zoo nkauj yog xav tau.
Binary hlau sulfides tuav cov lus cog tseg zoo li cov khoom siv hluav taws xob rau cov khoom siv hluav taws xob ua haujlwm siab vim tias lawv muaj cov khoom siv hluav taws xob ntau dua thiab muaj peev xwm ntau dua li mono-hlau sulfides.
Ntawm no, qhov kev tsim qauv thiab kev tsim khoom ntawm NiCo2S4 nano - sheets txhawb nqa ntawm cov pa roj carbon nitrogen-doped (NCF) (raws li SINOYQX carbonized melamine ua npuas ncauj) yog nthuav tawm ua lub electrode hloov pauv tshiab rau super-capacitors.
Ib txoj kev yooj yim ob kauj ruam tau tsim los rau kev loj hlob ntawm NiCo2S4 nanosheets ntawm NCF nrog kev nplaum zoo, uas cuam tshuam txog kev loj hlob ntawm Ni-Co precursor thiab tom qab ntawd hloov mus rau hauv NiCo2S4 nanosheets los ntawm cov txheej txheem sulfidation.
Tau txais txiaj ntsig los ntawm cov yam ntxwv ntawm cov khoom sib xyaw thiab 3D electrode architectures, NiCo2S4 / NCF electrode qhia txog kev ua tau zoo electrochemical zoo heev nrog lub peev xwm ultrahigh (877 Fg −1 ntawm 20 Ag −1 ) thiab kev ruaj khov zoo heev.
Ntxiv mus, ib lub cuab yeej asymmetric super-capacitor uas tsis muaj binder kuj tseem tsim los ntawm kev siv NiCo2S4 / NCF ua lub electrode zoo thiab cov pa roj carbon mesoporous (OMC)/NCF ua lub electrode tsis zoo; qhov no qhia tau tias muaj zog ceev ceev (≈45.5 Wh kg −1 ntawm 512 W kg −1 ).
