Yog li ntawd, tsov rog! Tesla: cylindrical ntsiab nkaus xwb, 4680. Volkswagen: uniform rectangular ntsiab

Thaum Lub Kaum Hli Ntuj Hnub Tim 2020, Tesla tau tshaj tawm qhov kev tsim cov qauv ntawm tes cylindrical tshiab, 4680, uas yuav tshwm sim sai sai hauv cov tsheb. Rau lub hlis tom qab, Volkswagen tshaj tawm tus qauv cuboid txuas uas yuav dhau los ua lub hauv paus rau yuav luag tag nrho pawg, suav nrog cov tsheb thauj khoom.

Volkswagen tab tom ntes tau, tsim kom muaj kev swb tsuas yog 2-3 xyoos piv rau Tesla

Cov txheej txheem

• Volkswagen tab tom ntes tau, tsim kom muaj kev swb tsuas yog 2-3 xyoos piv rau Tesla
  • Tag nrho qhov no txhais li cas rau cov neeg siv nruab nrab?

Muaj peb hom hlwb tam sim no siv hauv tsheb fais fab:

• cylindrical (cylindrical puab) yog siv los ntawm Tesla,
• rectangular (Lus Askiv prismatic), tej zaum feem ntau ntawm cov tsoos manufacturers, nws txiav txim siab ua nws Kev txhawj xeeb Volkswagen nyob rau hauv lub "single cell",
• sachet (pouch), uas tshwm sim qhov tseem ceeb tshaj plaws yog kom "sab tawm" lub roj teeb ntau npaum li qhov ua tau los ntawm lub peev xwm muab.

Txhua hom no muaj qhov zoo thiab qhov tsis zoo: cylindrical ib zaug tau nrov tshaj plaws (siv hauv koob yees duab thiab laptops), yog li Tesla thiab Panasonic tshwj xeeb hauv lawv. Lawv kuj lav qhov kev ruaj ntseg siab. Sachet lawv tso cai rau lub zog siab kom ua tiav, tab sis cov neeg tsim qauv yuav tsum nco ntsoov tias lawv tuaj yeem ua kom qhov ntim tau zoo vim tias lawv tsis muaj qhov qhib kom tso tawm cov pa roj. Cuboids cov no yog cov ntsiab lus ntawm lub hnab hauv ib qho nyuaj, txoj kev yooj yim tshaj plaws los sib sau ua ke (piv txwv li, los ntawm cov blocks) yog lub roj teeb uas npaj txhij, ntxiv rau, lawv muaj zog dua mechanically.

Volkswagen twb siv cov duab plaub, tab sis nws zoo nkaus li tias lawv cov qauv yog qhov tsawg kawg yog ib feem ntawm cov qauv tsim ntawm lub tsheb. Unified cells yuav tsum tshwm sim thawj zaug hauv 2023, thiab hauv 2030 lawv yuav tsum ua 80 feem pua ​​​​ntawm tag nrho cov hlwb siv:

Cov hlwb tshiab yuav tsis raug teeb tsa rau hauv cov qauv (los ntawm cell mus rau ntim), thiab tib hom ntawv (daim ntawv) yuav tsum muaj ntau hom chemistry hauv:

• hauv cov tsheb uas pheej yig tshaj lawv yuav nws LFP hlwb (lithium hlau phosphate)
• nrog cov khoom lag luam loj yuav thov cell muaj manganese (thiab qee qhov nickel)
• ntawm cov qauv xaiv tshwm NMC hlwb (nickel-manganese-cobalt cathodes),
• ... thiab ntxiv rau lawv, Volkswagen kuj tseem nco txog cov khoom siv hluav taws xob electrolyte, vim nws muaj 25% ntawm cov khoom ntawm QuantumScape. Solid-state hlwb twb tso cai rau 30% nce nyob rau hauv ntau thiab ib tug nqi nyob rau hauv 12 feeb es tsis txhob ntawm 20 (cov ntaub ntawv raws li prototypes):

Raws li rau lub anode, lub tuam txhab tsis ua tej yam preconceptions, tab sis hnub no nws yog kuaj graphite nrog silicon. Tam sim no xav paub: Porsche Taycan thiab Audi e-tron GT muaj silicon anodesua tsaug uas lawv tuaj yeem them nrog lub zog loj (tam sim no: txog 270 kW).

Thaum kawg Volkswagen xav siv txuas raws li cov qauv ntawm lub tsheb (cell mus rau lub tshuab) thiab nws zoo li cov qauv txheej txheem yuav raug yoog rau qhov ntawd. Txawm li cas los xij, ua ntej Pab Pawg mus txog theem no, nws yuav tsum dhau mus rau theem no. roj teeb tsis muaj modules (cell-rau-pob) - thawj lub tshuab ua hauv txoj kev no yuav yog qauv tsim los ntawm Artemis Audi project... Nws yog qhov ua tau tias peb yuav pom lub tswv yim ntawm lub tsheb no nyob rau xyoo 2021.

Modular roj teeb. Nws lub cev yog txuas. Cov kauj ruam tom ntej yog cov kev sib txuas uas tsis yog ballast, tab sis cov qauv ntawm lub tsheb - Volkswagen cell-rau-tsheb (c)

Cov ntsiab lus tshiab zoo li yuav tsim nyob rau hauv tag nrho 6 lub chaw tsim khoom uas Volkswagen xav tsim los ntawm 2030. (ib txhia nrog cov neeg koom tes). Thawj qhov tsim los ntawm Northvolt yuav tsim hauv Skelleftea, Sweden. Qhov thib ob yog nyob rau hauv Salzgitter (Lub Tebchaws Yelemees, txij li xyoo 2025). Qhov thib peb yuav nyob hauv Spain, Portugal lossis Fabkis (los ntawm 2026). Nyob rau hauv 2027, ib tsob nroj nyob rau sab hnub tuaj teb chaws Europe yuav tsum tau launched, suav nrog Poland., Czech koom pheej thiab Slovakia txais - tsis tau txiav txim siab. Nws tseem tsis tau paub tias qhov twg ob tsob ntoo kawg yuav raug tsim.

Tag nrho qhov no txhais li cas rau cov neeg siv nruab nrab?

Los ntawm peb qhov kev xav qhov txiaj ntsig tseem ceeb ntawm kev sib koom ua ke ntawm tes yog qhov txo qis ntawm cov nqi tsim khoom... Txij li thaum lawv yuav universal, lub automatics configured nyob rau hauv tib txoj kev yuav ua tau hauj lwm nyob rau hauv tag nrho cov nroj tsuag ntawm kev txhawj xeeb. Ib qho kev tshawb fawb soj ntsuam yog txaus rau ib hom chemistry. Nws yog tag nrho tej zaum yuav hloov mus rau tus nqi qis rau cov tsheb fais fab.

Thiab txawm hais tias qhov ntawd tsis tshwm sim, Tesla, Volkswagen, Audi thiab Skoda tuaj yeem ua rau tus nqi siab rau tus so ntawm lub khw. Vim tias siv cov khoom siv sab nraud (saib Hyundai, BMW, Daimler,…) ib txwm txhais tau tias tsis yooj yim dua thiab cov nqi siab dua.
