E-China, ii-supercapacitors zisetyenziswe kwiimoto zombane iminyaka emininzi.Ke ziziphi iingenelo ze-supercapacitors kwiimoto zombane?Kutheni i-super capacitors iphezulu kangaka?
Ii-capacitors eziphezulu
super capacitor, imoto yombane, ibhetri lithium
Abanikazi beemoto zombane bahlala bexhalabile ngoluhlu lokuhamba, kwaye zonke iiholide kuya kubakho izikhalazo.Makhe siqale sijonge umthombo wexhala lokuhamba ngenqanawa:
Ubuninzi bamandla epetroli kwizithuthi eziqhelekileyo yi-13,000 Wh/kg.Okwangoku, ubuninzi bamandla beebhetri ze-lithium eziqhelekileyo ziyi-200-300Wh / kg.Nangona kunjalo, ukuguqulwa kwamandla okusebenza kakuhle kwezithuthi zombane ezihlambulukileyo kumaxesha angama-2-3 aphezulu kunama-locomotives e-diesel.Ke ngoko, ukuze kusetyenziswe amandla ngobuchule obuphezulu, eyona ndlela ilungileyo kukunyusa ukuxinana kwamandla kwiibhetri ze-lithium.
Nangona ubuninzi bamandla bonyusiwe ukuya kumaxesha ali-10 elabhoratri, ibhetri ibuyiselwa emva kweentlawulo ezininzi kunye nokukhutshwa.
Ngoko ngaba kunokwenzeka ukwandisa ubuninzi bamandla ukuya kwinqanaba eliphakathi kwaye ulondoloze inani elifanelekileyo lentlawulo kunye nokukhutshwa?
Ii-Supercapacitors
I-Capacitor yenye yezona zinto zisisiseko ze-elektroniki.Ngamafutshane, iileyiti ezimbini ze-metal foils sandwich sheet insulating sheet, kunye negobolondo ekhuselayo yongezwa ngaphandle.Phakathi kwezi foil ezimbini kukho indawo apho amandla ombane agcinwa khona.I-capacitor isetyenziswa njengonikezelo lwamandla kwangoko, ngoko ke amandla ombane agciniweyo awaninzi, kwaye ubuninzi bamandla bubi kakhulu kunebhetri.
Kodwa i-capacitor inenzuzo yokuba ibhetri ayinayo: umrhumo kunye nobomi bokukhutshwa bude kakhulu - nokuba ngamakhulu amawaka amaxesha okuhlawula kunye nokukhutshwa, ukuthotywa kokusebenza kuncinci kakhulu.Ngoko ubomi bayo buyafana nemveliso ngokwayo.
Isizathu sokuba inentlawulo egqwesileyo kwaye ikhuphe ubomi kukuba i-capacitor yokugcina amandla isekelwe kwimigaqo yomzimba kwaye ayivelisi ukuphendula kweekhemikhali.
Ngoko ngoku umsebenzi kukwandisa amandla okugcina amandla ombane we-capacitor.Ngoko i-supercapacitor ibonakala.Injongo kukwenza i-capacitor i-reservoir, kungekhona nje ukunikezelwa kwamandla ngokukhawuleza.Kodwa ubunzima obukhulu yindlela yokuphucula ukuxinana kwamandla e-supercapacitors.
I-supercapacitor ingasetyenziselwa njengomthombo wamandla wezithuthi zombane emva kokunyusa ubuninzi bamandla.I-China sele iqalile ukusebenzisa le teknoloji.Kwi-2010 Shanghai World Expo, 36 iibhasi super capacitor zaboniswa.Ezi bhasi kudala zisebenza ngokuzinzileyo kwaye zisasebenza ngokwesiqhelo kude kube ngoku.
Iibhasi zeSupercapacitor eShanghai zinokubaleka iikhilomitha ezingama-40 ngemizuzu esi-7
Kodwa iteknoloji ayizange isasazeke kwezinye iindlela kunye nezinye izixeko.Oku kukwayingxaki "yokuhamba ngenqanawa" ebangelwa kukuxinana kwamandla aphantsi.Nangona ixesha lokutshaja lifinyeziwe kakhulu, kuthatha nje imizuzu embalwa ukutshaja ixesha elinye, kodwa linokuhlala malunga neekhilomitha ezingama-40 kuphela.Ukusetyenziswa kokuqala, ibhasi yayide ifune ukutshajwa ngalo lonke ixesha imisa.
Ukuxinana kwamandla kwezi supercapacitors akulunganga njengaleyo yeebhetri ze-lithium.Esona sizathu sisisiseko kukuba i-dielectric constant of the carbon-based materials in the supercapacitors is still not high enough.Kwinqaku elilandelayo, siza kuthetha ngokuphumelela kweTshayina ekuphuculeni ubuninzi bamandla e-supercapacitors.
I-JYH HSU (JEC)) ngumenzi we-supercapacitor waseTshayina okhethekileyo kuphando kunye nophuhliso, ukuveliswa kunye nokuthengiswa kwezinto ezahlukeneyo ze-elektroniki.Ukuba unemibuzo malunga namacandelo e-elektroniki okanye ufuna ukufuna intsebenziswano yezoshishino, ungaqhagamshelana nathi nangaliphi na ixesha.
