Amaseli e-Zinc ane-breakouts encane. Ukuminyana kwamandla aphezulu kanye nezinkulungwane zemijikelezo yomsebenzi
Amabhethri e-lithium-ion ayindinganiso ephelele kanye nebhentshimakhi yokugcina amandla. Kodwa abacwaningi bahlale befuna izakhi ezinikeza okungenani ukusebenza okufanayo ngezindleko zokukhiqiza eziphansi kakhulu. Enye yezinto ezithembisayo i-zinc (Zn).
Amabhethri e-Zn-x ashibhile futhi azobiza kakhulu. Kufanele nje bakhokhelwe
I-Zinc deposits ihlakazekile emhlabeni wonke, singayithola nasePoland - njengomphakathi esabaxhaphaza kusukela ku-2020 (!) Ikhulu leminyaka kuze kube sekupheleni kweminyaka eyi-12,9. I-Zinc iyinsimbi eshibhile futhi kulula ukuyithola kune-lithium njengoba iwusizo embonini, ukukhiqizwa komhlaba wonke kuyizigidi (izigidi ezingu-2019 ku-82) kunamashumi ezinkulungwane zamathani (izinkulungwane ezingu-2020 ku-XNUMX) njengoba kucatshangwa. beka encwadini. Ngaphezu kwalokho, i-zinc ibilokhu iyisisekelo samaseli kusukela ngekhulu lesi-XNUMX futhi isasetshenziswa kumaseli alahlwayo (isibonelo, amaseli e-alkaline asuselwa ku-zinc oxide ne-manganese).
Inselele ukuthola amaseli e-zinc ukuthi asebenze okungenani imijikelezo engamakhulu ambalwa ngenkathi egcina umthamo ohleliwe.... Inqubo yokushaja ibhethri nge-anode ye-zinc ibangela ukubekwa okungavamile kwama-athomu ensimbi ku-electrode, esikwazi ngokuthi ukukhula kwe-dendrite. Ama-dendrite akhula aze abhodloze izihlukanisi, afinyelele ku-electrode yesibili, abangele ukujikeleza okufushane, futhi abangele ukufa kweseli.
NgoMeyi 2021, kwashicilelwa iphepha lesayensi lapho kwachazwa ukuziphatha kweseli eline-electrolyte enosawoti we-fluorine. Usawoti uhlangana ne-zinc endaweni ye-anode ukwenza i-zinc fluoride. Isendlalelo se-junction sasikwazi ukungena kuma-ion, kodwa sivimbe ama-dendrites.... Kodwa-ke, into evikelwe ngale ndlela yayingafuni ngempela ukubuyisela ukukhokhiswa (ibinokumelana okuphezulu kwangaphakathi, umthombo).
Indlela engenzeka yokwandisa ukusebenza kwayo kabusha ichazwa komunye umsebenzi wocwaningo onikezwe ama-zinc cell cathodes asekelwe ethusi, i-phosphorus nesulfure. Imiphumela? Ngenkathi iseli elijwayelekile le-zinc linikeza amandla afinyelela ku-0,075 kWh / kg, amaseli akamuva e-zinc-air anama-cathode amasha. isithembiso 0,46 kWh / kg... Ngokungafani namaseli e-Zn-air edlule, ayevame ukulahlwa, kufanele ahlale izinkulungwane zemijikelezo yokusebenza, okungukuthi, ilungele ukusetshenziswa kwezimboni (umthombo).
Uma konke okutholakele kungahlanganiswa, kuqinisekiswe futhi kwandiswe ukukhiqizwa, amaseli e-zinc angaba yisisekelo sokugcina amandla ashibhile esikhathini esizayo.
Ukuvula isithombe: ibhethri le-zinc elisebenziseka kabusha ("ibhethri le-alkaline"). Ngokuya ngokujula kokukhishwa, ingakwazi ukumelana nemijikelezo yokusebenza engamakhulu amaningana (c) Lukas A CZE
Inothi elivela kubahleli be-www.elektrowoz.pl: Ezincwadini zolimi lwesiNgisi, ama-zinc air cell abizwa ngama-fuel cell ngoba athatha umoya-mpilo emoyeni. Ngokombono wethu, akunandaba ukuthi inqubo iyabuyiseleka emuva, i.e. amaseli angashajwa futhi akhishwe izikhathi eziningi.
Lokhu kungase kube nentshisekelo kuwe:
