Watsopano kugalimoto yokhala ndi batire la graphene? GAC: Inde, mu Aion V tikuyesa pompano. Kulipira 6C!
A Chinese GAC akuti adalandira chiphaso chachitetezo chankhondo cha "graphene battery". Akuyenera kulola kulipiritsa kawiri mphamvu yamasiku ano: pomwe lero chiwonjezeko chakupita patsogolo kwamagetsi ndi 3-3,5 C (mphamvu = 3-3,5 x mphamvu ya batri), batire ya graphene mugalimoto ya GAC akuti kulola kugwiritsa ntchito 6C.
Mabatire a graphene - angatipatse chiyani?

Kumbukirani: m'mabatire apamwamba a lithiamu-ion okhala ndi electrolyte yamadzimadzi, anode nthawi zambiri amapangidwa ndi kaboni kapena kaboni wopangidwa ndi silicon. Ma cathodes, nawonso, amatha kupangidwa kuchokera ku lithiamu-nickel-manganese-cobalt (NCM) kapena lithiamu-nickel-cobalt-aluminium (NCA). Panthawi yogwiritsira ntchito batri, ma ion a lithiamu amasuntha pakati pa ma electrode awiri, kupereka kapena kuvomereza ma elekitironi. Kodi graphene imalowa kuti mu zonsezi?
Eya, akadzazidwa ndi mphamvu zambiri, maatomu a lithiamu amatha kupanga zotuluka zotchedwa dendrites. Kuti atseke, titha kusintha ma electrolyte amadzimadzi kukhala olimba omwe ma tabu sangalowemo - umu ndi momwe amagwirira ntchito mu mabatire olimba (electrolyte yolimba). Tikhozanso kusiya electrolyte madzi, koma kukulunga cathode ndi zinthu ndi mkulu kwambiri kumakoka mphamvu ndipo nthawi yomweyo permeable kuti ayoni.
Ndipo apa graphene imabwera kudzapulumutsa - pafupifupi pepala limodzi la maatomu a carbon omangika:
GAC Aion V - tikudziwa chiyani
Tsopano tiyeni tipitirire ku chilengezo cha GAC. Wopanga waku China pano akuyesa mabatire a graphene amtundu wa Aion V ku Mohe, China. Mwachiwonekere, iye analandira chiphaso cha chitetezo cha usilikali kaamba ka iwo, mwinamwake chololeza kugwiritsiridwa ntchito m’magalimoto amagetsi. Kuchuluka kwa mphamvu zamabatire a graphene ziyenera kutero 0,28 kWh / kg, omwe maselo apamwamba a NCM amapereka - palibe chochita apa (gwero).
Kupambana kwakung'ono ndi kutalika kwa moyo. 1,6 zikwi zozungulira chitani. Sizidziwika ndendende zomwe zimatchulidwa, koma ngati ndi 1 C (kulipira / kutulutsa ndi mphamvu yofanana ndi mphamvu ya batri), zotsatira zake ndi zabwino kwambiri. Muyezo wamakampani ndi 500-1 mizungu.
Chidwi chachikulu pazipita kulipiritsa mphamvu... Ziyenera kukhala 6 C,ndi. batire yokhala ndi mphamvu, titi, 64 kWh - monga mu Kia e-Niro - titha kulipira ndi mphamvu yayikulu ya 384 kW. Tesla Model 3 yokhala ndi batire ya 74 kWh imatha kuthamanga mpaka 444 kW! Izo zikutanthauza kuti pambuyo 5 mphindi kulipiritsa galimoto idzatha osachepera makilomita 170 a utali weniweni (200 WLTP mayunitsi).
Batire ya graphene yomwe imagwiritsidwa ntchito mu GAC Aion V mwina ndiyotheka kokha 5-8 peresenti okwera mtengo kuposa muyezo lithiamu-ion batire... Kupanga kwamtundu wamagalimoto okhala ndi mabatire atsopano kuyenera kuyamba mu Seputembara 2021.

Ndemanga ya mkonzi www.elektrowoz.pl: Kugwiritsa ntchito graphene mu cell ya lithiamu-ion ndi imodzi mwazinthu zomwe zingatheke. Kafukufuku wazaka zaposachedwa akuwonetsa kuti ukadaulo womwewu ndiwotsogola kwambiri, kotero tikuyembekeza kuti GAC ipite njira ya graphene-NMC. Komabe, wopanga magalimoto samaulula tsatanetsatane, kotero kufotokozera pamwambapa kuyenera kuganiziridwa ngati zongopeka.
Izi zingakusangalatseni:
