Toyota ikuyesa mabatire a F-ion. Lonjezo: 1 km pa mtengo uliwonse
Toyota ikuyesa mabatire atsopano a fluoride-ion (F-ion, FIB) ndi Kyoto University. Malinga ndi asayansi, azitha kusunga mphamvu zochulukirapo kasanu ndi kawiri pa misa yama unit kuposa maselo akale a lithiamu-ion. Izi zikufanana ndi kachulukidwe mphamvu pafupifupi 2,1 kWh / kg!
Toyota yokhala ndi ma F-ion cell? Osati mofulumira
The prototype fluoride ion cell ali ndi fluoride yosadziwika, mkuwa, ndi cobalt anode ndi lanthanum cathode. Setiyi imatha kuwoneka ngati yachilendo - mwachitsanzo, fluorine yaulere ndi gasi - tiyeni tiwonjezere kuti lanthanum (chitsulo chosowa padziko lapansi) chimagwiritsidwa ntchito m'maselo a nickel-metal hydride (NiMH), omwe amagwiritsidwa ntchito mumitundu yambiri ya Toyota.
Chifukwa chake, chinthu chokhala ndi F-ion chimatha kuwonedwa ngati chosinthika cha NiMH ndikubwereka kudziko la maselo a lithiamu-ion, koma ndi mtengo wobwerera. Mtundu wopangidwa ndi Toyota umagwiritsanso ntchito electrolyte yolimba.
Ofufuza ku Kyoto awerengetsa kuti mphamvu yamphamvu ya cell ya prototype ndi kasanu ndi kawiri kuposa ya cell ya lithiamu-ion. Izi zikutanthawuza kuchuluka kwa galimoto yamagetsi (makilomita 300-400) yokhala ndi batri yofanana ndi yosakanizidwa yakale, monga Toyota Prius:
Kuchotsa batire ya Toyota Prius
Toyota idaganiza zopanga ma cell a F-ion kuti apange magalimoto omwe amatha kuyenda mtunda wa kilomita imodzi pamtengo umodzi. Malinga ndi akatswiri omwe atchulidwa ndi portal ya Nikkei, tikuyandikira malire a mabatire a lithiamu-ion, osachepera omwe akupangidwa pano.
Pali chinachake mu izi: akuti tingachipeze powerenga lithiamu-ion maselo ndi graphite anodes, NCA / NCM / NCMA cathodes ndi electrolytes madzi sangalole kuthawa osiyanasiyana upambana makilomita 400 kwa magalimoto ang'onoang'ono ndi pafupifupi 700-800 makilomita kwa magalimoto aakulu. . Kupambana kwaukadaulo ndikofunikira.
Koma kupambana kudakali kutali: selo la Toyota F ion limagwira ntchito pa kutentha kwakukulu, ndipo kutentha kumawononga ma electrode. Choncho, ngakhale kulengeza kwa Toyota kuti electrolyte yolimba idzafika pamsika kumayambiriro kwa 2025, akatswiri amakhulupirira kuti maselo a fluoride-ion sangagulitsidwe mpaka zaka khumi zikubwerazi (gwero).
