(1) Baƙar fata Carbon: Tsarin baƙar fata na carbon ana bayyana shi ta matakin haɗuwa da baƙar fata na carbon zuwa sarkar ko siffar innabi.Kyawawan barbashi, sarkar cibiyar sadarwa mai cike da ɗimbin yawa, ƙayyadaddun yanki na musamman, da naúrar, waɗanda ke da fa'ida don samar da tsarin sarrafa sarkar a cikin lantarki.A matsayin wakilin na'urori masu ɗorewa na gargajiya, baƙar fata carbon a halin yanzu shine mafi yawan abin da ake amfani da shi.Rashin hasara shi ne cewa farashin yana da yawa kuma yana da wuya a tarwatsa.

(2)Graphite: Conductive graphite ne halin da barbashi size kusa da cewa na tabbatacce kuma korau aiki kayan, a matsakaici takamaiman surface area, da kuma mai kyau lantarki watsin.Yana aiki a matsayin kumburi na cibiyar sadarwa mai gudanarwa a cikin baturi, kuma a cikin ƙananan lantarki, ba zai iya inganta haɓakawa kawai ba, har ma da iya aiki.

(3) P-Li: Super P-Li yana da ƙananan ƙananan ƙwayar ƙwayar cuta, kama da baƙar fata na carbon, amma matsakaicin takamaiman yanki, musamman a cikin nau'i na rassa a cikin baturi, wanda yake da fa'ida sosai don samar da hanyar sadarwa.Rashin hasara shi ne cewa yana da wuya a tarwatse.

(4)Carbon nanotubes (CNTs): CNTs sune wakilai masu gudanarwa waɗanda suka fito a cikin 'yan shekarun nan.Gabaɗaya suna da diamita na kusan 5nm da tsayin 10-20um.Ba za su iya yin aiki kawai a matsayin "wayoyi" a cikin hanyoyin sadarwa ba, amma kuma suna da tasirin Layer na lantarki sau biyu don ba da wasa ga manyan halaye na supercapacitors.Kyakkyawan yanayin zafinsa kuma yana taimakawa ga ɓarkewar zafi yayin cajin baturi da fitarwa, rage polarization baturi, inganta girman baturi da ƙarancin zafin jiki, da tsawaita rayuwar baturi.

A matsayin wakili na gudanarwa, ana iya amfani da CNTs a haɗe tare da wasu ingantattun kayan lantarki don haɓaka iya aiki, ƙididdigewa, da aikin sake zagayowar abu/batir.Ingantattun kayan lantarki da za a iya amfani da su sun haɗa da: LiCoO2, LiMn2O4, LiFePO4, polymer positive electrode, Li3V2(PO4)3, manganese oxide, da makamantansu.

Idan aka kwatanta da sauran jami'an gudanarwa na gama gari, carbon nanotubes suna da fa'idodi da yawa a matsayin ingantattun abubuwan gudanarwa na batir lithium ion.Carbon nanotubes suna da babban ƙarfin lantarki.Bugu da kari, CNTs suna da babban al'amari rabo, kuma ƙananan adadin adadin zai iya cimma madaidaicin ƙofa mai kama da sauran abubuwan ƙari (tsare nisan electrons a cikin fili ko ƙaura na gida).Tun da carbon nanotubes iya samar da wani sosai m electron kai cibiyar sadarwa, a conductivity darajar kama da na wani mai siffar zobe barbashi ƙari za a iya samu da kawai 0.2 wt% na SWCNTs.

(5)Graphenesabon nau'in nau'in nau'in nau'in nau'in nau'in carbon mai sassauƙa ne mai nau'i biyu tare da ingantacciyar wutar lantarki da yanayin zafi.A tsarin damar graphene takardar Layer zuwa manne da aiki abu barbashi, da kuma samar da wani babban adadin conductive lamba shafukan ga m da korau lantarki aiki barbashi, sabõda haka, da electrons za a iya gudanar a cikin wani biyu-girma sarari don samar da wani abu. babban yanki mai gudanar da cibiyar sadarwa.Don haka ana la'akari da shi azaman madaidaicin wakili a halin yanzu.

Baƙar fata na carbon da kayan aiki suna cikin lamba, kuma suna iya shiga cikin barbashi na kayan aiki don haɓaka ƙimar amfani da kayan aiki gabaɗaya.The carbon nanotubes ne a cikin batu line lamba, kuma za a iya interspersed tsakanin aiki kayan don samar da wani cibiyar sadarwa tsarin, wanda ba kawai ƙara conductivity, A lokaci guda, shi kuma iya aiki a matsayin wani partial bonding wakili, da kuma lamba yanayin graphene. lamba-da-fuska lamba ce, wanda zai iya haɗa saman kayan aiki don samar da babbar hanyar sadarwa ta yanki azaman babban jiki, amma yana da wahala a rufe kayan aiki gabaɗaya.Ko da adadin graphene ƙara da aka ci gaba da karuwa, yana da wuya a gaba daya yi amfani da aiki abu, da kuma yada Li ions da deteriorate da lantarki yi.Saboda haka, waɗannan abubuwa guda uku suna da kyakkyawan yanayin haɓakawa.Haɗa baƙar fata na carbon ko carbon nanotubes tare da graphene don gina ingantaccen hanyar sadarwa na iya ƙara haɓaka aikin lantarki gaba ɗaya.

Bugu da ƙari, daga hangen nesa na graphene, aikin graphene ya bambanta daga hanyoyi daban-daban na shirye-shirye, a cikin matakin raguwa, girman takardar da rabon baƙar fata na carbon, dispersibility, da kauri na lantarki duk suna shafar yanayi. na conductive jamiái sosai.Daga cikin su, tunda aikin wakili shine gina hanyar sadarwa don jigilar lantarki, idan wakiliyar da kanta ba ta warwatse ba, yana da wahala a gina hanyar sadarwa mai inganci.Idan aka kwatanta da wakilin baƙar fata na gargajiya na carbon, graphene yana da takamaiman yanki na musamman mai tsayi, kuma tasirin haɗin gwiwar π-π yana sa ya zama sauƙin haɓaka cikin aikace-aikace masu amfani.Saboda haka, yadda za a yi graphene ya zama tsarin watsawa mai kyau da kuma yin cikakken amfani da kyakkyawan aikinsa shine babbar matsala da ke buƙatar warwarewa a cikin aikace-aikacen graphene.
