QuantumScape idapereka chidziwitso chokhazikika. Malizitsani 4 C, kupirira 25 C, 0-> 80%. mu mphindi 15

QuantumScape, poyambira kupanga maselo olimba a electrolyte, adawonetsa magawo ake. Maluso awo ndi ochititsa chidwi: amalola kuti azilipira pa 4 ° C, kupirira mpaka 25 ° C, amapereka mphamvu zamagetsi mumtundu wa 0,3-0,4 kWh / kg ndi kuzungulira 1 kWh / l. JB Straubel, woyambitsa nawo Tesla, akuwona izi ngati zopambana.

Maselo olimba a QuantumScape m'magalimoto a Volkswagen patatha zaka pafupifupi 5?

QuantumScape yakhala yotchuka kawiri m'mbuyomu: kamodzi, pamene Volkswagen adakhala wogawana nawo wamkulu wa kampaniyo, ndipo kachiwiri, pamene JB Straubel, woyambitsa nawo Tesla, adakhala membala wa bungwe la oyang'anira. Tsopano zakhala zikumveka kachitatu: kampaniyo yatulutsa zotsatira za kafukufuku wake. Zimakhala zochititsa chidwi pazifukwa zingapo: selo lowoneka bwino limawonetsedwa lomwe limagwira ntchito kutentha kwanthawi zonse (madigiri 30 Celsius), ndipo zotsatira zake zimawonetsedwa kuti zitha kubwezeredwa.

QuantumScape Ceramic Cage ndi mbale yosinthika ya kukula kwa khadi yosewera. Pakona yakumanja yakumanja, mutha kuwona Purezidenti wa kampaniyo, Jagdeep Singh (c) QuantumScape.

Kodi tikukamba za chiyani? Maselo a QuantumScape ndi maselo a lithiamu omwe amagwiritsa ntchito electrolyte yolimba m'malo mwa electrolyte yamadzimadzi, popanda anode yosiyana. Anode yawo imakhala ndi ma ion a lithiamu panthawi yolipira (Li-zitsulo). Selo likatulutsidwa, ma lithiamu ion amapita ku cathode, anode imasiya kukhalapo.

Chithunzi chojambula cha selo yamakono ya lithiamu-ion (kumanzere) ndi selo la QuantumScape. Mu cell yachikale yochokera pamwamba, tili ndi electrode, graphite / silicon anode, nembanemba ya porous, lithiamu source cathode, ndi electrode. Zonsezi zimamizidwa mu electrolyte yomwe imathandizira kuyenda (c) kwa ma ion a QuantumScape.

Kulipira pa 4 C popanda kutsika

Kutsogola kofunikira ndikutha kulipiritsa ma cell a QuantumScape mpaka 4 ° C osawawononga. Palibe kuwonongeka, popeza electrolyte ya ceramic imalola kutuluka kwa ayoni a lithiamu, koma salola kuti lithiamu dendrites ikule. 4 C imatanthauza kuti ndi batire ya 60 kWh tidzafika pa mphamvu ya 240 kW, ndi 80 kWh kale 320 kW, ndi zina zotero.. Panthawi imodzimodziyo, tidzapereka mpaka 80 peresenti mu maminiti a 15, kotero kuti mphamvu yowonjezera sikhala yotsika kwambiri - idzakhala 192 ndi 256 kW, motero.

Mphamvu zotere zidzasanduka kubwezeretsanso kwamtunduwu pa liwiro la +1 200 km / h, i.e. + 20 Km / mphindi... Kuima kwa mphindi khumi ndi zisanu kuti mutambasule mafupa anu ndi chimbudzi kukupatsani pafupifupi makilomita 300 kapena kupitirira makilomita 200 a msewu waulere.

Kuthekera kwa "kusintha mwamakonda" kwa ma cell ndikosangalatsanso. Kampaniyo idadzitamandira kuyesa mpaka 25 C. Poganiza kuti tikhala tikugwiritsa ntchito "20 C yokha" galimoto yokhala ndi batire ya 60 kWh imatha kupirira kuwombera kwa 1,2 MW!

Kupitilira 800 ntchito zozungulira ndi ~ 10% kuwonongeka

Ubwino winanso waukulu wa ma cell a QuantumScape ndikukwera njinga zawo. Amafika mosavuta kuzungulira kwa 800 (ntchito = kulipira kwathunthu ndi kutulutsa) pa 1 ° C ndikulonjeza kukhazikika kwambiri pamagetsi otsika - ndipo chomalizacho chimapezeka m'magalimoto amagetsi.

Zitha kuwoneka kuti 800 ntchito zozungulira si zochuluka, koma ngati tiyika mtengo uwu pamakina, timapeza ziwerengero zazikulu. Tinene kuti tili ndi ma cell a QuantumScape ophatikizidwa kukhala batire ya 60 kWh. Kuthekera kumeneku kumakupatsani mwayi woyendetsa makilomita oposa 300 mosavuta. 800 m'zinthu ntchito ndi mtunda wa makilomita osachepera 240 zikwi (chithunzi pamwambapa).

Ndi mtunda wotero, maelementi akadalibe pafupifupi 90 peresenti ya mphamvu zawo, kotero amakulolani kuyendetsa makilomita oposa 300, koma makilomita 300 okha popanda kubwezeretsanso! Ngati kuwonongeka kwa mzere kukupitilirabe, komwe sitikudziwabe, pa 480 80 makilomita tidzafika pafupifupi XNUMX peresenti ya mphamvu ndi zina zotero.

Timawonjezera kuti lero chizindikiro chosinthira kapena kukonza batri ndi mphamvu ya pafupifupi 65-70 peresenti ya mphamvu yoyambirira.

Kupatula apo, kulumikizana ndi ndege?

JB Straubel, woyambitsa nawo Tesla ndipo tsopano ndi membala wa bungwe la oyang'anira a QuantumScape, akuwona zomwe kampaniyo ikuchita ngati yopambana.... Akugogomezera kuti kuwonjezereka kwadzidzidzi kwadzidzidzi kotereku sikofala kwambiri, ndipo Tesla adayesa kupita patsogolo kwa chiwerengero chimodzi m'zaka zaposachedwa. Maulaliki ochokera kuzinthu zina zoyambira nthawi zambiri amangoyang'ana pazigawo zosankhidwa ndikusiya ena, pomwe QuantumScape idawonetsa miyeso ingapo yokhudzana ndi kulimba komanso kulemedwa ndi kupirira.

M'malingaliro ake, zinthu zatsopanozi zitha kulola kupangidwa kwa ndege zamagetsi zomwe zili ndi mitundu yomwe timadziwa.

chiwonongeko

Palibe zithunzi zomwe zikuwonetsa ma cell a QuantumScape opangidwa. Tikayang'ana makanema, iwo ndi otupa kwambiri. Kusiyanaku kumawoneka ngati kokulirapo kwa 2-3 kuposa momwe ma cell a lithiamu-ion ali ndi anode opangidwa ndi graphite, omwe amatha kukhala ochepera popanga mabatire apamwamba kwambiri.

Zofunika kuziwona (pafupifupi maola 1,5):
