Tshiab rau lub tsheb nrog graphene roj teeb? GAC: Yog lawm, hauv Aion V peb tab tom sim nws tam sim no. Charge 6 C!
Tuam Tshoj GAC hais tias nws tau txais daim ntawv pov thawj kev nyab xeeb tub rog rau "graphene roj teeb". Nws yuav tsum tso cai them nyiaj ntawm ob zaug lub zog ntawm hnub no: thaum hnub no lub ncov ntawm kev nce qib hluav taws xob yog 3-3,5 C (lub zog = 3-3,5 x roj teeb muaj peev xwm), nws tau hais tias graphene roj teeb hauv lub tsheb GAC tso cai siv 6. C.
Graphene roj teeb - lawv tuaj yeem muab rau peb li cas?
Cov txheej txheem
- Graphene roj teeb - lawv tuaj yeem muab rau peb li cas?
- GAC Aion V - peb paub dab tsi
Nco qab: hauv cov roj teeb lithium-ion classic nrog cov kua electrolyte, cov anodes feem ntau yog ua los ntawm carbon lossis carbon doped nrog silicon. Cov cathodes, nyob rau hauv lem, tuaj yeem ua los ntawm lithium-nickel-manganese-cobalt (NCM) lossis lithium-nickel-cobalt-aluminium (NCA). Thaum lub sijhawm ua haujlwm roj teeb, lithium ions txav ntawm ob lub electrodes, pub dawb lossis txais cov khoom siv hluav taws xob. Qhov twg yog qhov chaw rau graphene nyob rau hauv tag nrho cov no?
Zoo, thaum loaded nrog lub zog siab, lithium atoms tuaj yeem tsim protrusions hu ua dendrites. Txhawm rau thaiv lawv, peb tuaj yeem hloov cov kua electrolyte mus rau ib qho khoom uas cov tabs yuav tsis nkag mus - qhov no yog nws ua haujlwm li cas hauv cov roj teeb hauv lub xeev (cov khoom electrolyte). Peb kuj tuaj yeem tso cov kua electrolyte, tab sis qhwv lub cathode nrog cov khoom siv nrog lub zog tensile siab heev thiab tib lub sijhawm permeable rau ions.
Thiab ntawm no graphene los rau kev cawm - yuav luag ib daim ntawv ntawm cov pa roj carbon atoms:
GAC Aion V - peb paub dab tsi
Tam sim no cia peb mus rau GAC tshaj tawm. Cov chaw tsim khoom suav tam sim no tab tom sim graphene roj teeb hauv Aion V qauv hauv Mohe, Suav. Thaj, nws tau txais daim ntawv pov thawj kev nyab xeeb ntawm tub rog rau lawv, tej zaum tso cai rau lawv siv hauv tsheb hluav taws xob. Lub zog ceev ntawm graphene roj teeb yuav tsum 0,28 kWh / kg, uas siab NCM hlwb muab - tsis muaj kev tawg ntawm no (qhov chaw).
Qhov kev tawg me me yog lub neej expectancy. 1,6, XNUMXk yiv xyaum. Nws tsis paub meej tias lub voj voog twg tau hais, tab sis yog tias nws yog 1 C (them / tso tawm nrog lub zog sib npaug ntawm lub peev xwm ntawm lub roj teeb), qhov tshwm sim yog qhov zoo heev. Cov txheej txheem kev lag luam yog 500-1 cycles.
Qhov loj tshaj xav paub lub zog them siab tshaj plaws. Nws yuav tsum yog 6 C, i.e. lub roj teeb uas muaj peev xwm ntawm, hais, 64 kWh - zoo li hauv Kia e-Niro - peb tuaj yeem them nrog lub zog siab tshaj plaws ntawm 384 kW. Tesla Model 3 nrog lub roj teeb 74 kWh tuaj yeem nrawm rau 444 kW! Nws txhais tau tias tom qab 5 feeb ntawm kev them nyiaj tshuab yuav ua kom tiav tsawg kawg yog 170 km ntawm qhov tseeb (200 WLTP units).
Cov roj teeb graphene siv hauv GAC Aion V ntseeg tau tias yog tsuas yog 5-8 feem pua ntau dua li tus qauv lithium-ion roj teeb. Kev tsim khoom ntawm lub tsheb nrog cov roj teeb tshiab yuav tsum pib thaum lub Cuaj Hlis 2021.

Editorial note www.elektrowoz.pl: Daim ntawv thov ntawm graphene hauv lithium-ion ntawm tes tsuas yog ib qho ntawm cov kev siv tau. Kev tshawb fawb nyob rau hauv xyoo tas los no qhia tau hais tias cov cuab yeej tshwj xeeb no yog qhov siab tshaj plaws, yog li peb cia siab tias GAC mus rau txoj kev graphene-NMC. Txawm li cas los xij, lub tuam txhab tsheb tsis tshaj tawm cov ntsiab lus, yog li cov lus piav qhia saum toj no yuav tsum raug suav hais tias yog kev kwv yees.
Qhov no yuav txaus siab rau koj:
