"Peb lub hlwb aluminium-ion (aluminium-ion) them 60 npaug sai dua lithium-ion hlwb." Wow! :)
Lub lim tiam tshiab thiab lub roj teeb tshiab. Australia's Graphene Manufacturing Group thov kom tsim cov hlwb raws li graphene thiab txhuas (ib yam khoom). Lawv hais tias "lawv them 60 npaug sai dua li cov lithium-ion zoo tshaj plaws," thiab "lawv tuaj yeem khaws peb lub zog ntau dua li lwm cov roj ntsha-ion txhuas."
Al-ion GMG hlwb. Nws tag nrho cov suab zoo dhau lawm
Cov txheej txheem
- Al-ion GMG hlwb. Nws tag nrho cov suab zoo dhau lawm
- Aluminium yog pheej yig, graphene yog kim
GMG aluminium ion hlwb yuav tsum yog nyob rau hauv daim ntawv ntawm laub-khawm cov ntsiab lus uas peb paub los ntawm, piv txwv li, cov yuam sij lossis cov khoom ua si me me. Tab sis them rau caum zaus sai dua suab zoo kawg li. Nws muaj raws li kev suav kawg los ntawm 1 rau 5 feeb. Zog ceev yog "peb zaug ntau dua li lwm cov ntsiab lus nrog aluminium ions." 0,15-0,16 kWh/kg.
Lub tuam txhab tuaj yeem khav theeb ntawm ib qho ntxiv: lub peev xwm kom tau txog li 7 kW ntawm lub zog los ntawm 1 kilogram ntawm cov hlwb. Qhov ntawd yog tawb nyob rau hauv ib tug qauv hluav taws xob tshebuas hnyav 250 kg, lawv tuaj yeem tsim hluav taws xob txog li 1,75 MW (!, 2 km) ntawm lawv lub ncov... Suab cosmic, yam tsawg kawg ntawm daim ntawv. Lub downside yog qhov kev khiav hauj lwm voltage ntawm tes, thaum lub sij hawm nws yog 1,7 V.
Siv graphene, ib qho txhuas ion cell qauv tsim los ntawm GMG
Thaum kawg, qhov hais txog kev siv graphene suab zoo txaus siab, vim hais tias cov kev daws teeb meem zoo li no tau tshwm sim: graphene cathode ua rau nws muaj peev xwm ncav cuag qib ntawm 0,2-0,3 kWh / kg thiab ua kom nws ua tau kaum lossis ntau pua txhiab tus khiav haujlwm. cycles (!). Daim ntawv tshaj tawm los ntawm Tuam Tshoj yog qhov txaus ntshai tshwj xeeb vim nws nyob ze rau Australia thiab kev sib raug zoo ntawm ob lub teb chaws. Zoo, Zhejiang University tau tsim ib qho yooj yim, tsis-flammable aluminium ion cell uas tuaj yeem them nqi hauv 1,1 vib nas this thiab khaws 91,7 feem pua ntawm nws cov peev txheej qub tom qab 250 cycles (qhov chaw).
Aluminium yog pheej yig, graphene yog kim
Ua hauj lwm ntawm txhuas ion hlwb tau mus rau ntau xyoo vim tias txhuas yog ib qho kev cog lus hlau zoo li lub tsev thaiv ntawm ion pub anode. Tab sis nws yuav tsum tau kim electrolytes thiab cathodes yog tias peb xav tiv thaiv nws los ntawm kev sib txuas nrog lwm cov ntsiab lus hauv lub xov tooj ntawm tes, vim tias cov ntawv cog lus zoo li no sai sai ua rau lub cev. Meanwhile, Graphene Manufacturing Group hais tias nws yuav tso tawm aluminium-ion khawm hlwb tom qab xyoo no lossis thaum ntxov 2022. Automotive sachets yuav tsum npaj kom txhij nyob rau hauv thaum ntxov 2024..
Automotive roj teeb raws li aluminium ion hlwb yuav tsis tsuas yog sib zog vim lawv lub zog ntau dua. Zoo GMG tshaj tawm tias Aluminium ion hlwb tsis muaj teeb meem nrog qhov kub thiab txias, yog li muaj lub caij nyoog uas lawv yuav tsis xav kom txias lossis rov ua kom sov.... Tsis tas li ntawd, yav tom ntej lawv yuav muaj cov duab zoo ib yam thiab muab cov hluav taws xob zoo ib yam li cov lithium-ion tam sim no, yog li lawv tuaj yeem hloov tau yooj yim rau cov roj teeb uas twb muaj lawm (qhov chaw).
Qhov no yuav txaus siab rau koj:
