I-Toyota ihlola amabhethri e-F-ion. Isithembiso: 1 km ngenkokhiso ngayinye

I-Toyota ihlola amabhethri amasha e-fluoride-ion (F-ion, FIB) ne-Kyoto University. Ngokusho kososayensi, bazokwazi ukugcina amandla aphindwe kasikhombisa ngobuningi beyunithi kunamaseli e-lithium-ion classical. Lokhu kuhambisana nokuminyana kwamandla okungaba ngu-2,1 kWh/kg!

IToyota enamaseli e-F-ion? Hhayi ngokushesha

I-prototype fluoride ion cell ine-fluoride engashiwongo, ithusi, ne-cobalt anode kanye ne-lanthanum cathode. Isethi ingase ibonakale ingavamile - isibonelo, i-fluorine yamahhala iyigesi - ngakho-ke ake sengeze ukuthi i-lanthanum (insimbi yomhlaba engavamile) isetshenziswa kumaseli we-nickel-metal hydride (NiMH), asetshenziswa kuma-hybrid amaningi akwaToyota.

Ngakho-ke, i-elementi enama-F-ion ekuqaleni ingabhekwa njengokuhlukile kwe-NiMH ngokuboleka emhlabeni wamaseli e-lithium-ion, kodwa ngenkokhiso ehlehlayo. Inguqulo eyakhiwe yiToyota nayo isebenzisa i-electrolyte eqinile.

Abacwaningi e-Kyoto baye babala ukuthi ukuminyana kwamandla okucatshangelwayo kweseli ye-prototype kuphindwe kasikhombisa kuneseli ye-lithium-ion. Lokhu kungasho ububanzi bemoto kagesi (300-400 km) enebhethri elilingana nehybrid endala evamile, njengeToyota Prius:

Ikhipha ibhethri leToyota Prius

AbakwaToyota banqume ukuthuthukisa ama-F-ion cell ukuze bakhe izimoto ezikwazi ukuhamba ikhilomitha elingu-1 ngenkokhelo eyodwa. Ngokusho kochwepheshe abacashunwe yi-portal ye-Nikkei, sisondela emkhawulweni wamabhethri e-lithium-ion, okungenani lawo akhiqizwayo okwamanje.

Kukhona okuthile kulokhu: kulinganiselwa ukuthi amaseli e-lithium-ion asendulo ane-graphite anode, ama-cathodes e-NCA / NCM / NCMA kanye nama-electrolyte aketshezi ngeke avumele ibanga lendiza lidlule amakhilomitha angama-400 ezimotweni ezincane kanye namakhilomitha angama-700-800 ezimotweni ezinkulu. . Kudingeka intuthuko kwezobuchwepheshe.

Kodwa ukuphumelela kusekude kakhulu: i-Toyota F ion cell isebenza kuphela emazingeni okushisa aphezulu, futhi amazinga okushisa aphezulu abhubhisa ama-electrode. Ngakho-ke, naphezu kwesimemezelo sikaToyota sokuthi i-electrolyte eqinile izofika emakethe ekuqaleni kuka-2025, ochwepheshe bakholelwa ukuthi amaseli e-fluoride-ion ngeke adayiswe kuze kube yiminyaka eyishumi ezayo (umthombo).
