Toyota tab tom sim F-ion roj teeb. Kev cog lus: 1 km ib tus nqi
Toyota tab tom sim tshiab fluoride-ion (F-ion, FIB) roj teeb nrog Kyoto University. Raws li cov kws tshawb fawb, lawv yuav muaj peev xwm khaws tau txog li xya zaus ntau zog rau ib chav tsev loj dua li cov lithium-ion classical. Qhov no sib raug rau lub zog ceev ntawm 2,1 kWh / kg!
Toyota nrog F-ion hlwb? Tsis ceev
Tus qauv fluoride ion cell muaj anode ntawm unspecified fluoride, tooj liab thiab cobalt thiab ib tug cathode ntawm lanthanum. Lub teeb yuav zoo li txawv txawv - piv txwv li, dawb fluorine yog ib qho roj - yog li cia peb ntxiv tias lanthanum (ib lub ntiaj teb tsis tshua muaj hlau) yog siv rau hauv cov nickel hlau hydride (NiMH) hlwb, uas yog siv nyob rau hauv ntau Toyota hybrids.
Yog li ntawd, ib qho khoom siv nrog F-ions tuaj yeem pib suav tias yog qhov txawv ntawm NiMH nrog qiv los ntawm lub ntiaj teb ntawm lithium-ion hlwb, tab sis nrog tus nqi rov qab. Lub version tsim los ntawm Toyota kuj siv cov khoom electrolyte.
Cov kws tshawb fawb hauv Kyoto tau suav tias qhov theoretical zog ceev ntawm cov qauv qauv yog xya npaug ntawm lithium-ion cell. Qhov no yuav txhais tau hais tias qhov ntau ntawm lub tsheb hluav taws xob (300-400 km) nrog lub roj teeb qhov loj ntawm lub qub qub hybrid, xws li Toyota Prius:
Tshem tawm Toyota Prius roj teeb
Toyota txiav txim siab los tsim F-ion hlwb los tsim cov tsheb uas tuaj yeem mus txog 1 km ntawm ib qho nqi. Raws li cov kws tshaj lij hais los ntawm Nikkei portal, peb tab tom mus txog qhov txwv ntawm lithium-ion roj teeb, tsawg kawg yog cov uas tam sim no tau tsim.
Muaj ib yam dab tsi hauv qhov no: nws yog kwv yees tias classic lithium-ion hlwb nrog graphite anodes, NCA / NCM / NCMA cathodes thiab kua electrolytes yuav tsis tso cai rau lub davhlau ntau tshaj 400 kilometers rau cov tsheb me thiab txog 700-800 kilometers rau cov tsheb loj. . Yuav tsum muaj kev hloov kho thev naus laus zis.
Tab sis qhov kev puas tsuaj tseem nyob deb heev: Toyota F ion cell ua haujlwm tsuas yog nyob rau hauv qhov kub thiab txias, thiab kub kub ua rau cov electrodes. Yog li ntawd, txawm tias Toyota tau tshaj tawm tias cov khoom siv electrolyte yuav ntaus lub lag luam thaum ntxov li xyoo 2025, cov kws tshaj lij ntseeg tias cov tshuaj fluoride-ion yuav tsis ua lag luam mus txog rau kaum xyoo tom ntej (qhov chaw).
