Zomwe zili mu batri ya lithiamu-ion kuchokera kugalimoto yamagetsi? Lithiamu ingati, cobalt ingati? Nali yankho
Volkswagen Group Components yasindikiza tchati chosonyeza kuchuluka kwa batri m'galimoto yamagetsi kutengera [lithium] nickel-cobalt-manganese cathodes. Uwu ndiye mtundu wodziwika kwambiri wa cell pamsika, kotero manambala amayimira kwambiri.
Batire yamagetsi: 8 kg lithiamu, 9 kg cobalt, 41 kg nickel.
Chitsanzo chinali batri yachitsanzo yolemera makilogalamu 400, i.e. mphamvu ya 60-65 kWh. Zikuoneka kuti ambiri kulemera kwake (126 makilogalamu, 31,5 peresenti) ndi Aluminiyamu matumba a zitsulo ndi ma modules. Ndizosadabwitsa: imateteza batri kuti isawonongeke, chifukwa chake iyenera kukhala yolimba.
Aluminiyamu pang'ono (zojambula za aluminiyamu) zimawonekeranso pamagetsi. Zimathandizira kutulutsa katundu kunja kwa selo.
Chachiwiri cholemera kwambiri ndi graphite (71 kg, 17,8%), pomwe anode amapangidwa. Lithiamu amaunjikana mu porous danga la graphite pamene batire ndi mlandu. Ndipo imatuluka pamene batire yatulutsidwa.
Chinthu chachitatu cholemera kwambiri ndi nickel (41 kg, 10,3%), chomwe ndi chinthu chachikulu, kuwonjezera pa lithiamu, cobalt ndi manganese, popanga ma cathodes amakono. Manganese 12 kilogalamu (3 peresenti), cobalt pali ngakhale zochepa, chifukwa 9 kilogalamu (2,3 peresenti), ndipo fungulo lili mu batire liti - 8 makilogalamu (2 peresenti).
Cobalt cube yokhala ndi 1 centimita m'mphepete. Tidagwiritsa ntchito chithunzichi powerengera kuchuluka kwa cobalt mu batri yagalimoto yamagetsi. Kenako pafupifupi 10 kg idatuluka, yomwe ili pafupifupi yabwino. (C) Alchemist-hp / www.pse-mndelejew.de
Mkuwa imalemera makilogalamu 22 (5,5 peresenti) ndipo ntchito yake ndi kuyendetsa magetsi. Pang'ono pang'ono pulasitiki, momwe maselo, zingwe, zolumikizira zimatsekedwa, ndipo ma modules amatsekedwa mumlandu - 21 kilogalamu (5,3 peresenti). Madzi ma elekitirodi, momwe ma ion a lithiamu amasuntha pakati pa anode ndi cathode, amapanga ma kilogalamu 37 (9,3 peresenti) ya kulemera kwa batri.
Na zamagetsi ndi 9 kilograms (2,3 peresenti), ndi wakhala, yomwe nthawi zina imagwiritsidwa ntchito ndi mbale zowonjezera zowonjezera kapena mu chimango, ndi ma kilogalamu atatu okha (3%). zosakaniza zina amalemera makilogalamu 41 (10,3 peresenti).
Chithunzi chotsegulira: Zomwe zili m'maselo mu chitsanzo cha batri ya lithiamu-ion (c) Volkswagen Group Components.
Zolemba mkonzi www.elektrowoz.pl: zowonetsedwa pamndandanda Magawo amagwirizana bwino ndi ma cell a NCM712Choncho, timaganiza kuti adagwiritsidwa ntchito m'magalimoto okhudzidwa ndi Volkswagen, kuphatikizapo magalimoto pa nsanja ya MEB, mwachitsanzo, Volkswagen ID.3. Ma PushEVs adanena kale pa izi miyezi isanu ndi umodzi yapitayo, koma chifukwa chosowa chitsimikiziro chovomerezeka, tapereka izi kamodzi kokha mwachinsinsi.
