Izinzuzo kanye nebubi kaphethiloli

Othile wabuza ku-inthanethi: Uma kuqhathaniswa namabhethri e-lithium, yiziphi izinzuzo nezingozi zamaseli kaphethiloli? Okulandelayo yimpendulo yabasebenzi bebhethri.

Mayelana nezinzuzo zokuqhathanisa nokubi, isisekelo siwukusebenzisa inhloso ngaphansi kwesisekelo esifanayo.

Qala uqhathanise ukufana nomehluko phakathi kwamabhethri amandla kaphethiloli namabhethri e-lithium, bese usebenzisa izinzuzo zokuqhathanisa ezihlukene kanye nokubi.

Izindlela zokusebenza ezihlukene: amandla kaphethiloli ebhethri afaka amandla amakhemikhali kanye nemiphumela yamandla kagesi; ibhethri ye-lithium ifaka amandla kagesi futhi ikhipha amandla kagesi. Ngakho-ke, i-fuel cell iyithuluzi lokuguqula amandla, futhi ibhethri ye-lithium iyidivayisi yokugcina amandla.

Isimiso sokukhishwa siyafana: ukukhishwa kwamandla ngebhethri yamandla kaphethiloli kanye nebhethri ye-lithium akuyona inqubo yokushisa, kodwa inqubo yomthombo wamandla we-isothermal, i-adiabatic electrochemical, ngakho amandla aphezulu.

Advantage

1. Uma kunegebe emphakathini wesintu emhlabeni, ukubaluleka kokulungiswa kwesakhiwo samandla esizayo sebhethri lamandla kaphethiloli ne-GT kulele kokuthi: izinsalela eziningi zebhethri ye-lithium zingamelela isabelo samandla seminyaka engu-1200, indlela yokuthuthukisa umsebenzi owusizo. we-terminal kusuka ekusetshenzisweni kwamandla ezinto ezimbiwa phansi, Indlela yokuvimbela umsebenzi owusizo ngendlela ethile futhi uqinisekise isakhiwo esihambisanayo esiguqukayo, ukhiye injini entsha ye-steam yenguquko yezimboni yemishini yokuguqula amandla (abantu bamane bayihlaziye), futhi ijwayele ukwandisa ukusetshenziswa kwamandla kumishini yokugcina amandla kagesi.

2. Lapho igebe livela ezimotweni, ikakhulukazi phansi, izimoto ezisebenza ngophethiloli zinamathuba amaningi kakhulu kunezimoto ezisebenza ngebhethri ye-lithium ukuba zifane nemboni yezimoto zanamuhla: amandla angabuyiselwa ngemizuzu engaphansi kwemi-3, futhi ibanga lidlule ku-400. amakhilomitha. Ezingxenyeni zokusabela kwamakhemikhali kanye nezingxenye zokusabela ze-oxidant ne-ejenti yokunciphisa (evame ukwaziwa ngokuthi uphethiloli), izimoto zamabhethri ezinamandla kaphethiloli zidinga kuphela ukuthwala izinhlobo ezimbili: izimoto zebhethri ye-lithium zizophatha amasampula womathathu nge-oxidizer kanye ne-ejenti yokunciphisa yebhethri ye-lithium. . (I-diaphragm engu-100-micron-thick) Uma ingasebenzi, kuzoba khona ukuzikhulula. Amabhethri e-lithium kufanele afinyelele umjikelezo ogcwele futhi avame ukubonakala ephaphathekile. Ngokungafani nezimoto zendabuko, zizoba namafutha, zomile, futhi zifakwe uphethiloli njalo lapho zijikeleza, ngakho-ke lapho ushayela Uma usebenzisa inkolelo-mbono embaxambili yebanga. Kungakho izimoto zanamuhla zama-fuel cell zinebanga lokuhamba elingaphezu kwamakhilomitha angama-600, kanti uhla lokuhamba lwezimoto ze-lithium-ion ngokuvamile lungaphansi kwamakhilomitha ayi-100. Amabhethri wamandla kaphethiloli wesitimela sikadizili afana negesi yemvelo, futhi ukusabela kuhlukaniswa ngokomzimba. Uphethiloli wangempela uyinqubo engokomzimba enejubane elisheshayo, kodwa iyonga, kuyilapho ukubuyiswa kwamandla amabhethri e-lithium kuyinqubo yokushaja, okungukuthi, ukusabela kwe-electrolysis, ukuphathwa noma ukuhlasela, sizokwenza Kukhona intuthuko yezobuchwepheshe ekuphenduleni Umkhawulo Wejubane.

ukuntuleka

1. Uma igebe liyidivayisi ye-elekthronikhi ephathekayo, ngenxa yokuhlukaniswa kwezingxenye ze-oxidizer, i-reductant ne-echo, ukuhlanganiswa kwesistimu ye-fuel power cell kunzima kakhulu kunebhethri ye-lithium ehlanganiswe ngokugcwele noma ezinye izinhlobo zamabhethri esibili;

2. Uma igebe liyisipele esingaphazanyiswa segridi, i-2NS Electronics idinga iseli lamandla kaphethiloli ukuthi ilethe i-oxidizer ehlukanisiwe kanye ne-reductant ebhethri, cishe okungenakwenzeka ukuyifeza;

Iziqu zezimboni: ukukhiqizwa kwemikhiqizo yamabhethri angenawo uphethiloli; amabhethri e-lithium asetshenziswa kumishini kagesi ephathekayo angenile embonini yokukhiqiza ngobuningi. Kepha ezimotweni, lezi zombili azihlanganisi ukukhiqizwa komkhiqizo. Ubunzima obujwayelekile bezobuchwepheshe ukuthi ungajwayelanisa kanjani impendulo ye-electrochemical nesidingo esikhulu esiguqukayo somthwalo wemoto ozwakalayo.

Ngamafuphi, lokhu kuyadida: Njengoba le mboni isivele ikhona, izimoto ze-lithium-ion zizothatha indawo yezimoto zenjini evuthayo yangaphakathi kalula kunezimoto zikaphethiloli. Iphutha lesimiso: Ukuthuthukiswa komkhiqizo kuqala ngezidingo zekhasimende. Imishini yokugunda utshani kanye nezinjini ezivuthayo ezingakaze zizwakale zingathuthukiswa ukuze kuzuzwe izinjini ezivuthayo zangaphakathi; izimoto zebhethri, amabhethri e-lithium ayigagasi lesine kusukela ngo-1900, futhi kubonakala sengathi abengekho kule minyaka eyishumi. Mancane kakhulu amathuba okuthi uzophumelela. Lona umsebenzi onzima.

Isibonisi esithembisa kakhulu yilesi: imoto eyi-hybrid eyakhiwe injini ye-fuel cell kanye nebhethri ye-lithium ingaphinda kabili amandla; 2) ukukhishwa kwezimoto zero; 3) ukufika okulula kokuphila kanye nenhloko-dolobha; 4) ukuqeda ukusetshenziswa kwemoto kwemithombo kawoyela ongahluziwe Ukuncika kuphela.
