QuantumScape: Tayamba kuyesa zolimba zosanjikiza 10 munjira yamalonda. Mabatire pakatha zaka 2 kapena kupitilira apo
QuantumScape, imodzi mwazoyambitsa zomwe zimagwira ntchito pama cell olimba a electrolyte, idadzitamandira poyesa mayeso ndi ma cell 10-wosanjikiza. Mu 2022, kampaniyo ikufuna kuwonetsa ma cell omwe ali ndi zigawo zingapo ndipo akufuna kumasula gulu loyamba loyeserera loyenera magalimoto mu 2023.
Maselo olimba a electrolyte ayenera kukhala amphamvu komanso opatsa mphamvu. Iwo akadali okhazikika
Maselo opangidwa ndi QuantumScape ndi machitidwe Kaya zitsulo popanda anode. Anode imapangidwa ndi lithiamu pa electrode pamene batire imayikidwa ndipo imawonongeka ikatulutsidwa. Mu cell lithiamu-ion, anode amapangidwa kuchokera ku mtundu wina wa kaboni (monga graphite), nthawi zina amapangidwa ndi silicon. Ngati mulibe graphite m'selo, sizitenga malo, kotero kuti mphamvu zambiri za selo ndi kulemera kwake zingagwiritsidwe ntchito kusunga charger.
QuantumScape yakhala ikuwoneka ngati yoyambira yabwino kwambiri ikafika pazinthu zolimba, koma ngakhale kampaniyo imati chitukuko chidzachedwa. Pambuyo pa maselo amodzi ndi anayi osanjikiza, zinali zotheka kupanga selo la 1-wosanjikiza, lomwe m'magawo angapo oyambirira a ntchito mu 4C-10C mode (kulipiritsa ndi kutulutsa ndi mphamvu yofanana ndi mphamvu ya selo) ndi C. / 1-C / 1 mode ikuwonetsa kuwonongeka pang'ono. Koma izi zimangozungulira 3-3 pama cell ochepa chabe, kampaniyo imanena mwachindunji za magawo oyambilira a ntchito:
Mayeso oyamba a 10-wosanjikiza ma cell a QuantumScape. Grafu ikuwonetsa kuti mizungu 20-36 yokha (c) ya QuantumScape idamalizidwa.
Ubwino wa kuyesera ndikuti umachitika pa kutentha pafupi ndi kutentha kwa chipinda (yerekezerani: kutentha kwa batire ya eCitaro kuchokera ku BlueSolutions). Ndipo kuti tikuchita ndi maselo akuluakulu mumtundu wa 7,5 × 8 cm. kuthekera kophatikiza ma electrolyte olimba a QuantumScape ndi ma cathodes otsika mtengo a lithiamu-iron-phosphate. Pomaliza, mwayi ndicholinga cha QuantumScape, chomwe chimalemba magawo onse oyeserera.
Maselo okhala ndi ma electrolyte olimba am'badwo wakale, ma cell osanjikiza 4. Maselo omwe adachita bwino kwambiri adataya pafupifupi 5-6 peresenti ya mphamvu zawo atagwiritsidwa ntchito mozungulira 400. Zosangalatsa ndizowoneka bwino zakusintha kwamphamvu yakutulutsa (ie, kuchuluka kwa batri) nthawi yomweyo isanakwane nambala 400 (c) QuantumScape.
Koma ndiko kutha kwa phindu. Maselo achitsulo a lithiamu amatupa panthawi yogwira ntchito chifukwa lifiyamu yomwe idamangidwa kale imapanga chinthu chosiyana mkati mwawo, anode. Chifukwa chake QuantumScape imawayesa ku 3,4 atmospheres of pressure kuti muchepetse njirayi. Izi zikutanthauza kuti kupsinjika komwe kungachitike kwa batire kungayambitse kulephera kwa batri mtsogolomo. N'chimodzimodzinso ndi tayala (puncture si zabwino), koma tayala si ofunika ngakhale 1/3 galimoto.
Komabe, kuthamanga kwambiri kwa thanki mwina ndizovuta kwambiri. Maselo 10-wosanjikiza ndi gawo lapakati poyerekeza ndi ma cell omwe ali ndi zigawo zingapo, mtundu womaliza uyenera kuyambitsidwa mu 2022. Okhawo adzapereka mphamvu zokwanira mphamvu kachulukidwe kuti athe kupikisana ndi tingachipeze powerenga lithiamu-ion maselo pa mtengo / ntchito chiŵerengero [QuantumScape sakunena]. Ma prototypes oyamba a cell oyenera kugwiritsidwa ntchito pamagalimoto adzawonekera pafakitale ya QS-0 ku California mu 2023, zaka ziwiri kuchokera pano, pomwe kampaniyo ikugwira ntchito yokulitsa kupanga zolekanitsa za ceramic (electrolytes).
10-layer QuantumScape Rigid Cell (kumanzere) ndi fakitale yatsopano yoyika QS-0 annealing line (c) QuantumSCape
Kuthekera kotchulidwa kogwiritsa ntchito ma electrolyte a QuantumScape m'maselo a LFP kumawoneka olimbikitsa kwambiri. Chifukwa cha izi, maselo oterowo amafika ku mphamvu ya 0,6-0,7 kWh / l, yomwe ikugwirizana ndi maselo abwino kwambiri a lithiamu-ion amakono okhala ndi nickel-manganese-cobalt cathodes ndi electrolytes yamadzimadzi. Munthu wolankhula: yokhala ndi electrolyte yolimba QuantumScape Porsche imatha kusunga batire la Taycan popanda kusintha chidebecho ndi kutsika kwakukulu kwa mtengo wake pogwiritsa ntchito LFP.
Zikuyembekezeka kuti ma cell azagulitsidwa kale kuposa kumapeto kwa 2023 ndi 2024.
Izi zingakusangalatseni:
