QuantumScape: Peb pib sim 10-txheej khib nyiab hauv hom lag luam. Cov roj teeb tom qab 2 xyoos lossis ntau dua
QuantumScape, ib qho ntawm cov kev pib ua haujlwm ntawm cov khoom siv hluav taws xob electrolyte, khav theeb ntawm kev sim pib nrog 10-txheej hlwb. Xyoo 2022, lub tuam txhab xav qhia cov hlwb nrog ntau lub kaum ob txheej thiab npaj yuav tso tawm thawj qhov kev sim ua kom haum rau tsheb hauv 2023.
Cov khoom electrolyte cell yuav tsum muaj zog thiab capacious. Lawv tseem nyob tas li
Cov hlwb tsim los ntawm QuantumScape yog cov kab ke Seb nws yog xim hlau tsis muaj anode... Lub anode muaj lithium ntawm lub electrode thaum lub roj teeb raug them thiab raug puas tsuaj thaum nws tawm. Nyob rau hauv ib tug raug lithium-ion cell, lub anode yog ua los ntawm ib co hom ntawm carbon (xws li graphite), tej zaum doped nrog silicon. Thaum tsis muaj graphite hauv cell, nws tsis siv qhov chaw, yog li feem ntau ntawm cov cell ntim thiab qhov hnyav tuaj yeem siv los khaws cov nqi.
QuantumScape tau ntev tau suav tias yog qhov kev pib ua lag luam zoo tshaj plaws thaum nws los txog rau lub xeev cov hlwb, tab sis txawm tias lub tuam txhab no thov tias kev loj hlob yuav qeeb... Tom qab ib- thiab plaub-txheej hlwb, nws muaj peev xwm tsim 1-txheej cell, uas nyob rau hauv thawj ob peb kaum ntawm lub voj voog ntawm kev ua hauj lwm nyob rau hauv 4C-10C hom (them them thiab tso tawm nrog lub hwj chim sib npaug ntawm lub peev xwm ntawm tes) thiab C / 1-C / 1 hom qhia tau tias muaj kev puas tsuaj me ntsis. Tab sis qhov no tsuas yog 3-3 lub voj voog rau ob peb lub hlwb xwb, lub tuam txhab ncaj qha hais txog cov theem pib ntawm kev ua haujlwm:
Thawj qhov kev sim ntawm 10-txheej QuantumScape hlwb. Daim duab qhia tau hais tias tsuas yog 20-36 lub voj voog (s) ntawm QuantumScape tau ua tiav.
Qhov kom zoo dua ntawm qhov kev sim yog tias nws tau ua tiav ntawm qhov kub thiab txias ze rau chav tsev (piv: qhov kub thiab txias ua haujlwm ntawm eCitaro roj teeb los ntawm BlueSolutions). Thiab hais tias peb tab tom cuam tshuam nrog cov hlwb loj hauv 7,5 × 8 cm hom.Qhov no kuj yog ib qho ntxiv. Qhov muaj peev xwm ntawm kev sib txuas cov khoom QuantumScape electrolyte nrog pheej yig lithium-iron-phosphate cathodes... Thaum kawg, qhov kom zoo dua yog lub hom phiaj ntawm QuantumScape, uas teev tag nrho cov kev ntsuas cuam tshuam.
Yav dhau los tiam khoom electrolyte hlwb, 4-txheej hlwb. Cov hlwb ua tau zoo tshaj plaws poob txog 5-6 feem pua ntawm lawv lub peev xwm tom qab 400 lub voj voog ntawm kev siv. Qhov kev txaus siab yog qhov pom tseeb pom pom ntawm qhov kev hloov pauv ntawm lub zog tawm (piv txwv li, lub peev xwm roj teeb) tam sim ntawd ua ntej lub voj voog tus lej 400 (c) QuantumScape
Tab sis qhov ntawd yog qhov kawg ntawm cov txiaj ntsig. Lithium hlau hlwb swell thaum lub sij hawm ua hauj lwm vim hais tias yav tas los khi lithium tsim ib qho khoom cais nyob rau hauv lawv - lub anode. Yog li QuantumScape sim lawv ntawm 3,4 atmospheres kom qeeb cov txheej txheem. Qhov no txhais tau hais tias muaj peev xwm depressurization ntawm lub roj teeb compartment tuaj yeem ua rau lub roj teeb tsis ua haujlwm yav tom ntej. Ib yam, ntawm chav kawm, nrog lub log tsheb (qhov kev sib tsoo tsis zoo), tab sis lub log tsheb tsis tsim nyog txawm tias 1/3 ntawm lub tsheb.
Txawm li cas los xij, lub siab tank siab yog qhov tsawg kawg ntawm cov teeb meem. Zoo, 10-txheej hlwb yog ib kauj ruam nruab nrab piv rau cov hlwb nrog ntau lub kaum ob txheej, qhov kawg version yuav tsum yog nyob rau hauv 2022. Tsuas yog lawv yuav muab lub zog txaus kom muaj peev xwm sib tw nrog classic lithium-ion hlwb ntawm tus nqi / kev ua haujlwm [QuantumScape tsis hais]. Thawj cov qauv qauv tsim nyog rau kev siv tsheb yuav tshwm sim ntawm QS-0 cog hauv California hauv 2023, ob xyoos txij li tam sim no, vim tias lub tuam txhab tam sim no ua haujlwm nthuav dav nws cov khoom siv hluav taws xob ceramic (electrolytes).
Rigid 10-txheej QuantumScape Cell (sab laug) thiab cov kab tshiab annealing ntsia ntawm QS-0 (c) QuantumScape cog
Qhov hais txog qhov muaj peev xwm siv QuantumScape electrolyte hauv LFP hlwb zoo li pheej hmoo heev. Vim li no, cov hlwb no ncav cuag lub zog ceev ntawm 0,6-0,7 kWh / l, uas sib haum rau cov lithium-ion zoo tshaj plaws niaj hnub nrog nickel-manganese-cobalt cathodes thiab kua electrolytes. Tus neeg hais lus: nrog QuantumScape Porsche khoom electrolyte tuaj yeem tuav lub peev xwm ntawm Taycan roj teeb tsis resizing lub thawv nrog rau qhov txo qis hauv nws tus nqi los ntawm kev siv LFP.
Cov hlwb tsis xav tias yuav ua lag luam mus txog thaum tig ntawm 2023 thiab 2024.
Qhov no yuav txaus siab rau koj:
