Toyota na gwada batir F-ion. Alkawari: 1 km kowace caji
Toyota na gwada sabbin batir fluoride-ion (F-ion, FIB) tare da Jami'ar Kyoto. A cewar masana kimiyya, za su iya tara kuzari har sau bakwai a kowace naúrar fiye da na al'ada na lithium-ion. Wannan yayi daidai da yawan kuzarin da ke kusa da 2,1 kWh/kg!
Toyota tare da sel F-ion? Ba sauri ba
Samfuran tantanin halitta na fluoride ion cell yana da fluoride, jan ƙarfe, da cobalt anode da ba'a bayyana ba da lanthanum cathode. Saitin na iya zama kamar na ban mamaki - alal misali, fluorine kyauta gas ne - don haka bari mu ƙara cewa ana amfani da lanthanum (ƙarfe mai ƙarancin ƙasa) a cikin ƙwayoyin nickel-metal hydride (NiMH), waɗanda ake amfani da su a yawancin matasan Toyota.
Saboda haka, tantanin halitta mai F-ions za a iya la'akari da farko azaman bambance-bambancen NiMH, aro daga duniyar ƙwayoyin lithium-ion, amma tare da cajin baya. Bambance-bambancen da Toyota ya ƙera shi ma yana amfani da ƙarfi mai ƙarfi.
Masu bincike daga Kyoto sun ƙididdige cewa yawan kuzarin ka'idar ƙirar tantanin halitta ya ninka na tantanin halitta na lithium-ion sau bakwai. Wannan yana nufin kewayon motar lantarki (kilomita 300-400) tare da baturi mai girman girman tsohuwar matasan, kamar Toyota Prius:

Toyota ya yanke shawarar samar da ƙwayoyin F-ion don ƙirƙirar motocin da za su iya tafiya kilomita 1 akan caji ɗaya. A cewar masana da tashar Nikkei portal ta ambata, muna gabatowa iyakar batirin lithium-ion, aƙalla waɗanda ake samarwa a halin yanzu.
Akwai wani abu zuwa ga wannan: an kiyasta cewa classic lithium-ion Kwayoyin da graphite anodes, NCA / NCM / NCMA cathodes da ruwa electrolytes ba za su ƙyale kewayo ya wuce 400 kilomita ga kananan motoci da kuma game da 700-800 kilomita ga manyan motoci. Ana buƙatar ci gaban fasaha.
Amma nasarar har yanzu yana da nisa: Toyota F ionic cell yana aiki ne kawai a yanayin zafi, kuma yanayin zafi yana lalata na'urorin lantarki. Saboda haka, duk da sanarwar Toyota cewa wani m electrolyte zai kasance a kasuwa a farkon 2025, masana sun yi imanin cewa fluoride ion Kwayoyin ba za a sayar har zuwa shekaru goma masu zuwa (source).
