Don tura iyakar ƙarfin ƙarfi na super-capacitors, sabon nau'in kayan lantarki tare da ingantattun gine-gine ana buƙata sosai.
Binary karfe sulfides rike babban alkawari a matsayin lantarki abu don high-yi makamashi ajiya na'urorin saboda suna bayar da mafi girma electrochemical ayyuka da kuma mafi girma iya aiki fiye da mono-metal sulfide.
A nan, an gabatar da ƙira da ƙera zanen nano na NiCo 2 S 4 waɗanda aka tallafa musu akan kumfa mai ɗauke da nitrogen (NCF) (bisa ga kumfa mai ɗauke da carbon melamine na SINOYQX) a matsayin sabon lantarki mai sassauƙa ga manyan masu ƙarfin lantarki.
An ƙirƙiri wata hanya mai sauƙi ta matakai biyu don haɓaka zanen NiCo 2 S 4 akan NCF tare da manne mai ƙarfi, wanda ya haɗa da haɓakar abin da ke gaba na Ni-Co da kuma canzawa zuwa zanen NiCo 2 S 4 ta hanyar tsarin sulfidation.
Da yake amfana daga fasalulluka na kayan aiki da kuma tsarin lantarki na 3D, na'urar lantarki ta NiCo 2 S 4 /NCF tana nuna ingantaccen aikin lantarki tare da ƙarfin lantarki mai ƙarfi (877 F g −1 a 20 A g −1 ) da kuma kyakkyawan kwanciyar hankali na keke.
Bugu da ƙari, ana ƙera na'urar super-capacitor mara asymmetric wacce ba ta da ɗaurewa ta hanyar amfani da NiCo2 S4 / NCF a matsayin electrode mai kyau kuma an tsara mesoporous carbon (OMC)/NCF a matsayin electrode mara kyau; wannan yana nuna yawan kuzari mai yawa (≈45.5 Wh kg −1 a 512 W kg −1 ).
