Ososayensi badale amaseli e-sodium-ion (Na-ion) ane-electrolyte eqinile • ELECTRIC CARS
Ososayensi baseNyuvesi yase-Austin (Texas, USA) benze amaseli e-Na-ion ane-electrolyte eqinile. Azikakalungeli ukukhiqizwa, kodwa zibukeka zithembisa: kwezinye izici zifana namaseli e-lithium-ion, angakwazi ukumelana nemijikelezo yokusebenza engamakhulu amaningana, futhi asebenzise into eshibhile futhi efinyelelekayo - i-sodium.
I-asphalt, i-graphene, i-silicon, isulfure, i-sodium - lezi zinto nezakhi zizokwenza kube nokwenzeka ukuthuthukisa izakhi zikagesi esikhathini esizayo. Zinento eyodwa abafana ngazo: zitholakala kalula (ngaphandle kwe-graphene) futhi zithembisa ukusebenza okufana, futhi mhlawumbe okungcono nakakhulu esikhathini esizayo, i-lithium.
Umbono othakazelisayo ukufaka i-lithium esikhundleni se-sodium. Zombili izakhi ziyingxenye yeqembu elifanayo lezinsimbi ze-alkali, zombili zisebenza ngokulinganayo, kodwa i-sodium iyisici sesithupha esigcwele kakhulu oqweqweni lomhlaba futhi singayithola ngemali ephansi. Kumaseli e-Na-ion athuthukiswe eTexas, i-lithium ku-anode ithathelwa indawo yi-sodium, futhi ama-electrolyte avuthayo athathelwa indawo ngama-electrolyte esibabule aqinile. (umthombo).
Ekuqaleni, i-ceramic cathode yayisetshenziswa, kodwa ngesikhathi sokusebenza (ukwamukela ukushaja / ukudluliswa kwemali) yashintsha usayizi futhi yabhidlika. Ngakho-ke, yathathelwa indawo i-cathode eguquguqukayo eyenziwe ngezinto eziphilayo. Iseli elakhiwe ngale ndlela lisebenze ngaphandle kokwehluleka emijikelezweni yokushaja / yokukhipha engaphezu kuka-400, futhi i-cathode ithole amandla amakhulu angama-0,495 kWh / kg (leli xabiso akufanele lididaniswe namandla alo lonke iseli noma ibhethri).
> I-Tesla Robotaxi kusukela ngo-2020. Uyolala futhi uTesla uyahamba uyokwenzela imali.
Ngemva kokuthuthukiswa okuqhubekayo kwe-cathode, kwakungenzeka ukuthi kufinyelele izinga lika-0,587 kWh / kg, cishe elihambisana namanani atholakala ku-cathode yamaseli e-lithium-ion. Ngemuva kwemijikelezo yokushaja engu-500, ibhethri ikwazile ukubamba amaphesenti angama-89 womthamo wayo.ephinde ihambisane nemingcele [ebuthakathaka] yamaseli e-Li-ion.
Amaseli e-Na-ion asebenza nge-voltage ephansi kunamaseli e-lithium-ion, ngakho-ke angasetshenziswa ukunika amandla ama-electronics aphathwayo. Kodwa-ke, iqembu lase-Austin liphinde lanquma ukuthuthela kuma-voltage aphezulu ukuze amaseli asetshenziswe ezimotweni zikagesi. Kungani? Enye yemingcele eyinhloko yemoto ingamandla ayo, futhi incike ngokuqondile kumandla wamanje kanye ne-voltage kuma-electrode.
Kuyafaneleka ukungeza ukuthi uJohn Goodenough, umsunguli wamaseli e-lithium-ion, uvela eNyuvesi yase-Austin.
