Ku cusub baabuur leh baytari graphene? GAC: Haa, Aion V hadda waanu tijaabinaynaa. Ku dallacaya 6C!
GAC ee Shiinaha ayaa sheegtay in ay heshay shahaadada badbaadada milatariga ee "batteriga graphene". Waxaa loo malaynayaa in la oggolaado in lagu dallaco laba jeer awoodda maanta: marka maanta heerka ugu sarreeya ee horumarinta korantada uu yahay 3-3,5 C (awood = 3-3,5 x awoodda batteriga), waxaa la sheegay in batteriga graphene ee gaariga GAC uu oggol yahay isticmaalka 6 C.
Baytariyada Graphene - maxay na siin karaan?

- GAC Aion V - maxaan naqaan
Xusuusnow: baytariyada lithium-ion-ka caadiga ah ee leh dareeraha dareeraha ah, anodes-yada waxaa badanaa laga sameeyaa kaarboon ama kaarboon oo leh silikoon. Katoodhada, markeeda, waxaa laga samayn karaa lithium-nickel-manganese-cobalt (NCM) ama lithium-nickel-cobalt-aluminium (NCA). Inta lagu jiro hawlgalka batteriga, ions lithium-ku waxay u dhexeeyaan laba electrodes, ku deeqaya ama aqbalaya electrons. Aaway meesha graphene ee waxaas oo dhan?
Hagaag, marka lagu shubo awood sare, atamka lithium-ku waxay samayn karaan soo-baxyo loo yaqaan dendrites. Si loo xakameeyo, waxaan u bedeli karnaa electrolyte dareere ah mid adag oo aan tabsyadu geli doonin - tani waa sida ay uga shaqeyso baytariyada adag ee adag (electrolyte adag). Waxaan sidoo kale ka tagi karnaa dareeraha dareeraha ah, laakiin ku duub cathode walxo leh awood cufan oo aad u sareysa isla markaana la dhaafi karo ions.
Oo halkan graphene waxay u timaadaa samatabbixinta - ku dhawaad hal-cabbir xaashida atamka kaarboon ee xidhan:
GAC Aion V - maxaan naqaan
Hadda aan u gudubno ku dhawaaqista GAC. Soo saaraha Shiinaha ayaa hadda ku tijaabinaya baytariyada graphene model Aion V ee Mohe, Shiinaha. Sida muuqata, wuxuu ka helay shahaadada badbaadada milatariga, malaha u oggolaanaya in loo isticmaalo gawaarida korontada. Cufnaanta tamarta ee baytariyada graphene waa inay noqotaa 0,28 kWh / kg, kuwaas oo unugyada NCM ee horumarsan ay bixiyaan - ma jiraan wax horumar ah halkan (ilo).
Horumarka yar waa rajada nolosha. 1,6k wareegyo dhaqanka. Si sax ah looma garanayo wareegyada lagu sheegay, laakiin haddii ay tahay 1 C (ku dallacaadda / ku shubista awoodda la mid ah awoodda batteriga), natiijadu aad bay u wanaagsan tahay. Heerka warshaduhu waa 500-1 wareegyo.
Xiisaha ugu weyn awoodda ugu badan ee dallacaadda. Waa inay noqotaa 6 C, i.e. baytari awood u leh, dheh, 64 kWh - sida Kia e-Niro - waxaan ku dallaci karnaa ugu badnaan 384 kW. Tesla Model 3 oo wata baytari 74 kWh ah ayaa dardar galin kara 444 kW! Taas macnaheedu waa ka dib 5 daqiiqo oo lacag ah mashiinka waa la dhamaystiri doonaa ugu yaraan 170 kiiloomitir oo kala duwan oo dhab ah (200 oo unug WLTP ah).
Bateriga graphene ee loo isticmaalo GAC Aion V ayaa la rumeysan yahay inuu yahay kaliya 5-8 boqolkiiba ayaa ka qaalisan baytariga caadiga ah ee lithium-ion. Wax soo saarka taxanaha ah ee baabuurka leh baytariyada cusub waa inuu bilaabmaa Sebtembar 2021.

Xusuus qor www.elektrowoz.pl: Codsiga graphene ee la soo bandhigay ee unugga lithium-ion waa mid ka mid ah codsiyada suurtagalka ah. Cilmi baaristii sanadihii ugu dambeeyay waxay muujineysaa in tignoolajiyadan gaarka ah ay tahay tan ugu horumarsan, sidaa darteed waxaan fileynaa in GAC ay tagto wadada graphene-NMC. Si kastaba ha ahaatee, soo saaraha baabuurtu ma soo bandhigo faahfaahinta, sidaas darteed sharraxaadda kor ku xusan waa in loo tixgeliyaa mala-awaal.
Tani waxay ku xiisaynaysaa:
