I-QuantumScape inikeze idatha yesimo esiqinile. Shaja 4 C, imelana nokungu-25 C, 0-> 80%. emizuzwini eyi-15

I-QuantumScape, isiqalisi sokuthuthukisa amaseli e-electrolyte aqinile, yaqhosha ngemingcele yamaseli ayo. Amakhono abo ahlaba umxhwele: avumela ukushaja ku-4 ° C, ukumelana no-25 ° C, anikeze ukuminyana kwamandla ebangeni lika-0,3-0,4 kWh / kg futhi azungeze 1 kWh / l. U-JB Straubel, umsunguli we-Tesla, ubona lokhu njengempumelelo.

Amaseli e-QuantumScape aqinile ezimotweni zakwaVolkswagen ngemuva kweminyaka engaba ngu-5?

I-QuantumScape isidume kabili esikhathini esidlule: kanye, lapho iVolkswagen iba umnikazi wamasheya oyinhloko wenkampani, futhi okwesibili, lapho u-JB Straubel, umsunguli we-Tesla, eba yilungu lebhodi labaqondisi. Manje sekunomsindo okwesithathu: inkampani ikhiphe imiphumela yocwaningo lwayo. Zihlaba umxhwele ngezizathu ezimbalwa: iseli elinosayizi ojwayelekile liyaboniswa elisebenza ezingeni lokushisa elivamile (30 degrees Celsius), futhi imiphumela iboniswa ingaphinda ikhiqizeke.

I-QuantumScape Ceramic Cage iyipuleti eliguquguqukayo elilingana nekhadi lokudlala. Ekhoneni eliphezulu kwesokudla, ungabona umongameli wenkampani, uJagdeep Singh (c) QuantumScape.

Sikhuluma ngani? Amaseli e-QuantumScape angamaseli e-lithium asebenzisa i-electrolyte eqinile esikhundleni se-electrolyte ewuketshezi, ngaphandle kwe-anode ehlukile. I-anode yabo iqukethe i-lithium ion ngesikhathi sokushaja (i-Li-metal). Lapho iseli likhishwa, i-lithium ion iya ku-cathode, i-anode iyayeka ukuba khona.

Umdwebo wesakhiwo weseli yesimanje ye-lithium-ion (kwesokunxele) kanye neseli ye-QuantumScape. Kuseli yakudala evela phezulu, sine-electrode, i-graphite/silicon anode, ulwelwesi olunezimbotshana, i-lithium source cathode, kanye ne-electrode. Konke lokhu kucwiliswa ku-electrolyte eyenza kube lula ukugeleza (c) kwama-ion e-QuantumScape.

Ishaja ngo-4 C ngaphandle kokuncishiswa

Intuthuko ebalulekile ikhono lokushaja amaseli e-QuantumScape afika ku-4 ° C ngaphandle kokuwacekela phansi. Akukho ukuwohloka, njengoba i-electrolyte ye-ceramic ivumela ukugeleza kwe-lithium ion, kodwa ayivumeli i-lithium dendrites ukuba ikhule. I-4 C isho ukuthi ngebhethri engu-60 kWh sizofinyelela emandleni okushaja angu-240 kW, nama-80 kWh kakade angu-320 kW, njll.. Ngesikhathi esifanayo, sizokhokhisa amaphesenti angu-80 emaminithini angu-15, ngakho-ke amandla okushaja aphakathi ngeke abe ngaphansi kakhulu kunomkhawulo - azoba ngu-192 no-256 kW, ngokulandelana.

Amandla anjalo azophenduka abe ukugcwaliswa kabusha kobubanzi ngesivinini esingu-+1 200 km / h, i.e. +20 km/min... Ukuma kwemizuzu eyishumi nanhlanu ukuze welule amathambo akho kanye nendlu yangasese kuzokunika cishe amakhilomitha angu-300 noma ngaphezu kwamakhilomitha angu-200 othelawayeka.

Amathuba "okwenza ngokwezifiso" amaseli nawo ayathakazelisa. Inkampani yaqhosha ngezivivinyo ezifika ku-25 C. Sicabanga ukuthi sizosebenzisa "kuphela" 20 C, imoto enebhethri engu-60 kWh ingamelana nokudutshulwa okungu-1,2 MW!

Imijikelezo yemisebenzi engaphezu kuka-800 ene-~ 10% yokuwohloka

Enye inzuzo enkulu yamaseli e-QuantumScape ukuhamba kwawo ngamabhayisikili aphezulu. Bafinyelela kalula emijikelezweni elinganiselwa ku-800 (umsebenzi = ukushaja okugcwele nokukhishwa) ku-1°C futhi bathembisa ukuqina okwengeziwe ngamandla aphansi - kanti lena yakamuva ingatholakala ezimotweni zikagesi.

Kungase kubonakale sengathi imijikelezo yemisebenzi engu-800 ayiningi, kodwa uma sibeka leli nani emshinini, sithola izinombolo ezinkulu. Ake sithi sinamaseli e-QuantumScape ahlanganiswe abe ibhethri elingu-60 kWh. Lo mthamo ikuvumela ukuthi ushayele kalula amakhilomitha angaphezu kuka-300. Imijikelezo engu-800 yomsebenzi iyi-mileage okungenani amakhilomitha ayizinkulungwane ezingu-240 (umdwebo ongenhla).

Nge-mileage enjalo, izakhi zisagcina cishe amaphesenti angu-90 omthamo wazo, ngakho zikuvumela ukuthi ushayele amakhilomitha angaphezu kuka-300, kodwa amakhilomitha angu-300 nje ngaphandle kokushaja! Uma ukucekelwa phansi komugqa kuqhubeka, esingakazi ngakho, kumakhilomitha angama-480 80 sizofinyelela cishe amaphesenti angu-XNUMX wamandla nokunye.

Sengeza ukuthi namuhla isignali yokushintsha noma ukulungisa ibhethri iwumthamo wamaphesenti angaba ngu-65-70 womthamo wangempela.

Phela, izixhumanisi ezindizeni?

U-JB Straubel, umsunguli kaTesla futhi manje oyilungu lebhodi labaqondisi be-QuantumScape, ubona impumelelo yenkampani njengempumelelo.... Ugcizelela ukuthi ukukhuphuka kwamandla okungazelelwe okunjalo akuvamile kakhulu, futhi uTesla ulinganise inqubekelaphambili ngamaphesenti anedijithi eyodwa eminyakeni yamuva. Amaphrezentheshini asuka kwezinye iziqalo ngokuvamile ayegxile kumapharamitha akhethiwe futhi ashiya amanye, kuyilapho i-QuantumScape ibonise inani lezilinganiso eziphathelene kokubili ukuqina nomthwalo nokubekezela.

Ngokombono wakhe, izakhi ezintsha zingavumela ukudalwa kwezindiza zikagesi ezinobubanzi esizijwayele.

Azikho izithombe ezibonisa amaseli e-QuantumScape ashajiwe. Uma sibheka i-animation, zivuvukele kakhulu. Umehluko ubonakala okungenani uphindwe izikhathi ezingu-2-3 kunasesimweni samaseli e-lithium-ion ane-anode esekelwe ku-graphite, okungaba umkhawulo lapho udala amabhethri aphezulu.

Ifanele ukubonwa (cishe amahora angu-1,5 wezinto):
