Incazelo:
Njenge-carbon material ene-conductivity ephezulu kanye nendawo ethile ephezulu, i-carbon nanotubes ingathuthukisa inhlayiya nokusatshalaliswa kwezinto ezisebenzayo, ithuthukise ukushaja nokwamukeleka kokukhishwa kwama-electrode, ikhulise amandla okukhipha ibhethri nokusebenza komjikelezo.
Umthelela wokwengeza okuqukethwe okuhlukile kwe-carbon nanotubes (CNT) kanye ne-carbon black ekusebenzeni kwe-electrochemical kwepuleti elingalungile lebhethri le-lead-asidi uye wacwaningwa.Ukwengeza inani elifanele lama-CNT kungakhuphula ivolumu yembotshana yangaphakathi ye-electrode engalungile, kuthuthukise i-particle morphology yezinto ezisebenzayo, kwenze usayizi wezinhlayiyana ufane kakhulu, futhi kuthuthukise ukusebenza kwe-kinetic ye-electrochemical reaction.Lapho i-0.5% CNT yengezwa, umthamo wokuqala wokukhipha ku-1 C wanda ngo-3%, futhi impilo yepuleti le-electrode ku-2C no-60s umjikelezo wokukhipha ucishe uphindwe kabili.Imithelela yezinhlobo ezahlukene nokuqukethwe kwama-carbon nanotubes okwengezwe ku-electrode eyinegethivu yebhethri le-lead-acid endaweni engaphezulu yepuleti le-electrode kanye nokusebenza kwebhethri kwacwaningwa ngokuhlolwa.
Ukuhlola kubonisa ukuthi ama-carbon nanotubes angakhuthaza ukusatshalaliswa okufanayo kwezinto ezisebenzayo futhi enze inethiwekhi ephumelelayo ye-three-dimensional conductive;ama-carbon nanotubes angathuthukisa ukusebenza kwebhethri, futhi umthamo wokuqala webhethri ungakhuphuka ufike ku-6.8%.Umthamo ungandiswa kakhulu ekushiseni okuphansi -15 °C 20.7%.Ingathuthukisa ngempumelelo izinga lokugcinwa komthamo webhethri.
Ama-carbon nanotubes anezindonga eziningi aphathwe ngamakhemikhali afakwe ezintweni ze-anode zamabhethri e-lead-acid, enziwe ama-electrode, futhi izici zomjikelezo ngaphansi kwenkokhiso ehlukene nezimo zamanje zokukhipha zahlolwa.Umthelela we-carbon nanotubes kumthamo, impilo yomjikelezo kanye nomsebenzi waphenywa Ukuhlaziywa kwe-X-ray diffraction kuqinisekisile ukwakheka kwe-PbO2 ku-anode plate, kanye nokwengezwa kwama-carbon nanotubes anezindonga eziningi epuleti le-anode kungathuthukisa izinga lokusebenzisa elisebenzayo. izinto zokwakha kanye nokucindezela ngempumelelo ukunciphisa ukusebenza kahle.
Isimo Sesitoreji:
I-Carbon nanotubes (CNTs) kufanele igcinwe endaweni evaliwe, gwema ukukhanya, indawo eyomile.Isitoreji sezinga lokushisa legumbi silungile.
