IiNanotubes zeCarbon ezinodonga olunye (SWCNTs)zisetyenziswa kakhulu kwiintlobo ezahlukeneyo zeebhetri. Nazi iintlobo zebhetri apho i-SWCNTs ifumana usetyenziso:
1) Ii-Supercapacitors:
Ii-SWCNTs zisebenza njengezixhobo ezifanelekileyo ze-electrode kwii-supercapacitors ngenxa yendawo yazo ethile ephezulu kunye nokuhanjiswa okugqwesileyo. Benza amaxabiso okukhutshwa ngokukhawuleza kwaye babonise ukuzinza komjikelo obalaseleyo. Ngokubandakanya ii-SWCNTs kwiipolymers eziqhubayo okanye ii-oxide zetsimbi, ubuninzi bamandla kunye nobuninzi bamandla e-supercapacitors bunokuphuculwa ngakumbi.
2) Iibhetri zeLithium-ion:
Kwintsimi yeebhetri ze-lithium-ion, i-SWCNTs ingasetyenziselwa njengezongezo eziqhubayo okanye izinto ze-electrode. Xa zisetyenziswa njengezongezo eziqhubayo, ii-SWCNTs zongeza ukuqhutywa kwemathiriyeli ye-electrode, ngaloo ndlela iphucula ukusebenza kwebhetri ukukhupha intlawulo. Njengezinto ze-electrode ngokwabo, ii-SWCNTs zibonelela ngeendawo ezongezelelweyo ze-lithium-ion zokufakela, ezikhokelela ekwandiseni umthamo kunye nokuzinza komjikelo ophuculweyo webhetri.
3) Iibhetri zesodium:
Iibhetri ze-sodium-ion zifumene ingqwalasela enkulu njengezinye iibhetri ze-lithium-ion, kwaye ii-SWCNTs zibonelela ngamathemba athembisayo kwesi sizinda ngokunjalo. Ngokuqhuba kwabo okuphezulu kunye nokuzinza kwesakhiwo, i-SWCNTs yinto efanelekileyo yokukhetha izinto ze-sodium-ion battery electrode.
4) Ezinye iintlobo zebhetri:
Ukongeza kwezi zicelo zikhankanywe ngasentla, ii-SWCNTs zibonisa amandla kwezinye iindidi zebhetri ezifana neeseli zepetroli kunye neebhetri zomoya we-zinc. Ngokomzekelo, kwiiseli zepetroli, i-SWCNTs inokusebenza njengenkxaso ye-catalyst, iphucula umsebenzi kunye nokuzinza kwe-catalyst.
Indima ye-SWCNTs kwiibhetri:
I-1) I-Additives Conductive: I-SWCNTs, kunye ne-conductivity ephezulu yombane, inokudibaniswa njengezongezo eziqhubayo kwi-solid-state electrolytes, ukuphucula i-conductivity yazo kwaye ngaloo ndlela iphucula ukusebenza kwebhetri-ukukhutshwa kwebhetri.
I-2) Izinto ze-Electrode: I-SWCNTs ingasebenza njenge-substrates ye-electrode materials, eyenza ukulayishwa kwezinto ezisebenzayo (ezifana ne-lithium metal, sulfure, i-silicon, njl.) ukuphucula i-conductivity kunye nokuzinza kwesakhiwo se-electrode. Ngaphaya koko, indawo ethile ephezulu ephezulu yee-SWCNTs ibonelela ngeziza ezisebenza ngakumbi, ezikhokelela kuxinano lwamandla aphezulu ebhetri.
I-3) Izixhobo zoKwahlula: Kwiibhetri eziqinileyo, ii-SWCNTs zingaqeshwa njengezinto zokwahlula, ezinikezela ngeziteshi zothutho ze-ion ngelixa zigcina amandla omatshini kunye nokuzinza kweekhemikhali. Ubume be-porous ye-SWCNTs igalelo ekuphuculeni i-ion conductivity kwibhetri.
I-4) Izinto ezixubileyo: I-SWCNTs inokudibaniswa kunye nezinto eziqinileyo ze-electrolyte ukuze zenze i-electrolyte edibeneyo, idibanise i-conductivity ephezulu ye-SWCNTs kunye nokhuseleko lwe-electrolyte eqinile. Izixhobo ezinjalo ezidibeneyo zisebenza njengezinto ezifanelekileyo ze-electrolyte kwiibhetri eziqinileyo.
I-5) Izinto zokuQinisekisa: I-SWCNTs inokuphucula iimpawu zemishini ye-electrolytes eqinile, iphucula ukuzinza kwesakhiwo sebhetri ngexesha leenkqubo zokukhutshwa kwentlawulo kunye nokunciphisa ukuthotywa kokusebenza okubangelwa utshintsho lwevolumu.
I-6) Ulawulo lwe-Thermal: Ngokuhamba kakuhle kwe-thermal conductivity, i-SWCNTs ingaqeshwa njengezinto zokulawula ukushisa, ukuququzelela ukutshatyalaliswa kobushushu obusebenzayo ngexesha lokusebenza kwebhetri, ukuthintela ukushisa, kunye nokuphucula ukhuseleko lwebhetri kunye nobomi.
Ukuqukumbela, ii-SWCNTs zidlala indima ebalulekileyo kwiintlobo ezahlukeneyo zebhetri. Iipropathi zabo ezizodwa zenza ukuhanjiswa okuphuculweyo, ukuxinana kwamandla okuphuculweyo, ukuzinza kolwakhiwo oluphuculweyo, kunye nolawulo olusebenzayo lobushushu. Ngokuqhubela phambili kunye nophando kwi-nanotechnology, ukusetyenziswa kwe-SWCNTs kwiibhetri kulindeleke ukuba kuqhubeke nokukhula, okukhokelela ekusebenzeni okuphuculweyo kwebhetri kunye namandla okugcina amandla.
