Dab tsi yog suav nrog hauv lithium-ion roj teeb los ntawm lub tsheb fais fab? Lithium ntau npaum li cas, cobalt ntau npaum li cas? Nov yog cov lus teb
Volkswagen Group Cheebtsam tau luam tawm ib daim ntawv qhia qhia lub roj teeb ntawm tes ntawm lub tsheb fais fab raws li [lithium] nickel-cobalt-manganese cathodes. Qhov no yog hom xovtooj nrov tshaj plaws ntawm kev ua lag luam, yog li tus lej yog tus sawv cev heev.
Hluav taws xob cov roj teeb: 8 kg lithium, 9 kg cobalt, 41 kg nickel.
Ib qho piv txwv yog cov qauv roj teeb uas hnyav 400 kilograms, i.e. muaj peev xwm ntawm 60-65 kWh. Nws hloov tawm tias feem ntau ntawm nws qhov hnyav (126 kg, 31,5 feem pua) yog Aluminium casings ntawm ntim thiab modules. Tsis xav tsis thoob: nws tiv thaiv lub roj teeb los ntawm kev sib tsoo kev puas tsuaj, yog li nws yuav tsum ua kom ntev.
Ib qho me me ntawm aluminium (aluminium foil) kuj tshwm sim ntawm cov electrodes. Nws ua hauj lwm kom tso tawm lub load sab nraum lub cell.
Qhov thib ob hnyav tshaj cov khoom xyaw yog graphite (71 kg, 17,8%), los ntawm cov anode yog tsim. Lithium accumulates nyob rau hauv qhov chaw ntxeem tau ntawm graphite thaum lub roj teeb them. Thiab nws tawm thaum lub roj teeb tawm.
Qhov thib peb hnyav tshaj cov khoom xyaw yog npib tsib xee (41 kg, 10,3%), uas yog lub ntsiab tseem ceeb, ntxiv rau lithium, cobalt thiab manganese, rau cov creation ntawm niaj hnub cathodes. Manganese yog 12 kg (3 feem pua), cobalt muaj tsawg dua, vim hais tias 9 kilograms (2,3 feem pua), thiab tus yuam sij yog nyob rau hauv lub roj teeb xim - 8 kg (2 feem pua).
Cobalt lub voos xwmfab nrog 1 centimeter ntug. Peb thawj zaug siv daim duab no los xam cov ntsiab lus cobalt ntawm lub tsheb fais fab roj teeb. Tom qab ntawd hais txog 10 kg tawm, uas yuav luag zoo tagnrho. (C) Alchemist-hp / www.pse-mendelejew.de
Tooj liab hnyav 22 kg (5,5 feem pua) thiab nws lub luag haujlwm yog ua hluav taws xob. Tsawg me ntsis los ntawm yas, nyob rau hauv uas cov hlwb, cables, connectors raug kaw, thiab modules yog kaw nyob rau hauv ib rooj plaub - 21 kilograms (5,3 feem pua). Ua kua cov roj ntsha, nyob rau hauv uas lithium ions txav ntawm lub anode thiab cathode, ua ib tug whopping 37 kilograms (9,3 feem pua) ntawm lub roj teeb qhov hnyav.
Na hluav taws xob yog 9 kg (2,3 feem pua), los ntawm tau ua, uas yog qee zaum siv nrog cov phaj ntxiv los yog hauv cov ncej, nws tsuas yog 3 kilograms (0,8%). lwm cov khoom xyaw lawv hnyav 41 kg (10,3 feem pua).

Editorial note www.elektrowoz.pl: tso tawm hauv daim ntawv proportions zoo heev nrog NCM712 hlwbYog li, peb xaus lus tias lawv tau siv nyob rau hauv cov tsheb ntawm Volkswagen kev txhawj xeeb, nrog rau cov tsheb ntawm MEB platform, piv txwv li, Volkswagen ID.3. PushEVs twb tau xav txog qhov no dhau rau lub hlis dhau los, tab sis vim tsis muaj kev lees paub tseeb, peb tau muab cov ntaub ntawv no tsuas yog ib zaug hauv hom zais cia.
Qhov no yuav txaus siab rau koj:
