Yini efakwe ebhethri ye-lithium-ion evela emotweni kagesi? Ingakanani i-lithium, ingakanani i-cobalt? Nansi impendulo
I-Volkswagen Group Components ishicilele ishadi elibonisa okuqukethwe kwebhethri yemoto kagesi esekelwe [lithium] nickel-cobalt-manganese cathodes. Lolu uhlobo lweseli oludume kakhulu emakethe, ngakho izinombolo zimelela kakhulu.
Ibhethri likagesi: 8 kg lithium, 9 kg cobalt, 41 kg nickel.
Isibonelo kwakuyibhethri yemodeli enesisindo esingamakhilogremu angu-400, i.e. namandla angu-60-65 kWh. Kuvela ukuthi iningi lesisindo salo (126 kg, amaphesenti angu-31,5) yilo I-Aluminium izikhwama zeziqukathi namamojula. Akumangazi: ivikela ibhethri ekulimaleni kokushayisana, ngakho-ke kufanele iqine.
Inani elincane le-aluminium (i-aluminium foil) liyavela kuma-electrode. Isebenza ukukhulula umthwalo ngaphandle kweseli.
Isithako sesibili esinzima kakhulu i-graphite (71 kg, 17,8%), lapho kwenziwa khona i-anode. I-lithium inqwabelana endaweni eyimbotshana yegraphite lapho ibhethri ishajwa. Futhi iyaphuma uma ibhethri likhishwa.
Isithako sesithathu esinzima kakhulu yi i-nickel (41 kg, 10,3%), okuyisici esiyinhloko, ngaphezu kwe-lithium, i-cobalt ne-manganese, ekudaleni ama-cathodes anamuhla. I-Manganese amakhilogremu angu-12 (amaphesenti angu-3), cobalt kukhona okuncane nakakhulu, ngoba amakhilogremu angu-9 (amaphesenti angu-2,3), futhi ukhiye usebhethri lithu - 8 kilograms (2 amaphesenti).
I-cobalt cube enomkhawulo oyisentimitha elingu-1. Siqale sasebenzisa lesi sithombe ukubala okuqukethwe kwe-cobalt kwebhethri lemoto kagesi. Kwabe sekuphuma cishe ngo-10 kg, okucishe kufane. (C) I-Alchemist-hp / www.pse-mndelejew.de
I-Copper inesisindo esingamakhilogremu angama-22 (amaphesenti angu-5,5) futhi indima yaso wukuqhuba ugesi. Kancane kancane plastic, lapho amaseli, izintambo, izixhumi zivaliwe, futhi amamojula afakwe ecaleni - amakhilogremu angu-21 (amaphesenti angu-5,3). Uketshezi i-electrolyte, lapho i-lithium ion ihamba phakathi kwe-anode ne-cathode, ihlanganisa amakhilogremu angu-37 (amaphesenti angu-9,3) wesisindo sebhethri.
Na elekthronikhi amakhilogremu angu-9 (amaphesenti angu-2,3), ngo waba, ngezinye izikhathi ezisetshenziswa nezingcwecwe zokuqinisa ezengeziwe noma kuhlaka, zingamakhilogremu angu-3 kuphela (0,8%). ezinye izithako zinesisindo esingamakhilogremu angu-41 (amaphesenti angu-10,3).
Ukuvula isithombe: Okuqukethwe kweseli kusampula yebhethri ye-lithium-ion (c) Izingxenye Zeqembu le-Volkswagen.
Inothi lokuhlela elithi www.elektrowoz.pl: liboniswa ohlwini izilinganiso zihambisana kahle kakhulu namaseli e-NCM712Ngakho-ke, siphetha ngokuthi zisetshenziswe ezimotweni zokukhathazeka kwe-Volkswagen, kuhlanganise nezimoto endaweni yesikhulumi se-MEB, isibonelo, i-Volkswagen ID.3. I-PushEVs isivele icabange ngalokhu ezinyangeni eziyisithupha ezedlule, kodwa ngenxa yokuntuleka kokuqinisekiswa okusemthethweni, sinikeze lolu lwazi kanye kuphela kwimodi eyimfihlo.
