I-QuantumScape: Siqale ukuhlola okuqinile kwezendlalelo ezingu-10 ngefomethi yokuthengisa. Amabhethri ngemva kweminyaka emi-2 noma ngaphezulu
I-QuantumScape, enye yeziqalo ezisebenza kumaseli e-electrolyte aqinile, yaziqhenya ngokwethula izivivinyo ngamaseli anezendlalelo eziyi-10. Ngo-2022, inkampani ifuna ukukhombisa amaseli anezendlalelo eziyishumi nambili futhi ihlela ukukhipha iqoqo lokuqala lokuhlola elilungele izimoto ngo-2023.
Amaseli e-electrolyte aqinile kufanele abe namandla futhi abe namandla. Zisalokhu zinjalo
Amaseli athuthukiswe yi-QuantumScape amasistimu Ukuthi i-metallic ngaphandle kwe-anode... I-anode iqukethe i-lithium ku-electrode lapho ibhethri lishajwa futhi liyabhujiswa lapho likhishwa. Kuseli elivamile le-lithium-ion, i-anode yenziwe ngohlobo oluthile lwekhabhoni (njenge-graphite), ngezinye izikhathi olufakwe nge-silicon. Uma ingekho i-graphite esitokisini, ayithathi isikhala, ngakho iningi lomthamo wengqamuzana nesisindo kungasetshenziswa ukugcina ukushaja.
I-QuantumScape sekuyisikhathi eside ithathwa njengesiqalo esithembisa kakhulu uma kukhulunywa ngamaseli aqinile, kodwa ngisho nale nkampani ithi ukuthuthukiswa kuzohamba kancane... Ngemuva kwamaseli anesendlalelo esisodwa nezine, kwakungenzeka ukudala iseli elingungqimba olu-1, okwathi emashumini ambalwa okuqala emijikelezo yokusebenza kumodi ye-4C-10C (ukushaja nokukhipha amandla alingana nomthamo weseli) futhi Imodi ye-C / 1-C / 1 ibonisa ukuwohloka okuncane. Kepha lokhu kuyimijikelezo engu-3-3 kuphela yamaseli ambalwa, inkampani isho ngokuqondile ngezigaba zokuqala zomsebenzi:
Ukuhlolwa kokuqala kwamaseli e-QuantumScape anezendlalelo ezingu-10. Igrafu ibonisa ukuthi imijikelezo engu-20-36 kuphela ye-QuantumScape eqediwe.
Inzuzo yokuhlolwa ukuthi yenziwa ezingeni lokushisa eliseduze negumbi lokushisa (qhathanisa: izinga lokushisa elisebenzayo lebhethri le-eCitaro kusuka ku-BlueSolutions). Nokuthi sibhekene namaseli amakhulu kakhulu ngefomethi engu-7,5 × 8 cm. Lokhu futhi kuyinhlanganisela ithuba lokuhlanganisa i-electrolyte eqinile ye-QuantumScape ne-lithium-iron-phosphate cathodes eshibhile... Okokugcina, inzuzo wumgomo we-QuantumScape, obala yonke imingcele yokuhlola efanele.
Isizukulwane sangaphambilini samaseli e-electrolyte aqinile, amaseli anezingqimba ezi-4. Amaseli asebenza kabi kakhulu alahlekelwa cishe ngamaphesenti angu-5-6 womthamo wawo ngemva kwemijikelezo engama-400 yokusetshenziswa. Okuthakaselayo ama-pulsations abonakala ngokucacile oshintsho kumandla okukhipha (okungukuthi, umthamo webhethri) ngokushesha ngaphambi kwenombolo yomjikelezo 400 (c) QuantumScape
Kodwa lokho ukuphela kwezinzuzo. Amaseli ensimbi ye-lithium ayakhukhumala ngesikhathi sokusebenza ngoba i-lithium ebiboshwe ngaphambilini idala into ehlukile kuwo - i-anode. Ngakho-ke i-QuantumScape iyabavivinya ku-3,4 atmospheres ukuze yehlise ijubane inqubo. Lokhu kusho ukuthi ukucindezeleka okungenzeka kwekhompathimenti yebhethri kungaholela ekwehlulekeni kwebhethri ngokuzayo. Okufanayo, yiqiniso, ngesondo (i-puncture ayilungile), kodwa isondo alifanelekile ngisho ne-1/3 yemoto.
Kodwa-ke, umfutho wethangi ophezulu cishe yiwona omncane wezinkinga. Hhayi-ke, amaseli anezendlalelo eziyi-10 ayisinyathelo esimaphakathi uma kuqhathaniswa namaseli anezendlalelo eziyishumi nambili, inguqulo yokugcina okufanele ibe ngo-2022. Yibo kuphela abazonikeza ukuminyana kwamandla okwanele ukuze bakwazi ukuncintisana namaseli e-lithium-ion akudala ngokwenani / ukusebenza [I-QuantumScape ayisho]. Amaseli okuqala e-prototype afanele ukusetshenziswa kwezimoto azovela embonini ye-QS-0 e-California ngo-2023, eminyakeni emibili kusukela manje, njengoba inkampani okwamanje isebenzela ukwandisa ukukhiqizwa kwayo kwezihlukanisi ze-ceramic (ama-electrolytes).
Iseli ye-QuantumScape enezingqimba ezi-10 eziqinile (kwesobunxele) kanye nolayini wokudonsa amanzi ofakwe e-QS-0 (c) embonini ye-QuantumSCape
Amathuba okukhulunywe ngawo okusebenzisa i-QuantumScape electrolyte kumaseli e-LFP abukeka ethembisa kakhulu. Ngenxa yalokhu, amaseli anjalo afinyelela ukuminyana kwamandla ka-0,6-0,7 kWh / l, okuhambisana namaseli e-lithium-ion anamuhla angcono kakhulu ane-nickel-manganese-cobalt cathodes kanye nama-electrolyte awuketshezi. Umuntu okhulumayo: nge-QuantumScape Porsche electrolyte eqinile ingagcina umthamo webhethri le-Taycan ngaphandle kokushintsha usayizi wesitsha ngokwehla okukhulu kwenani layo ngokusebenzisa i-LFP.
Amaseli akulindelekile ukuthi enziwe ezentengiso kuze kube sekupheleni kuka-2023 no-2024.
Lokhu kungase kube nentshisekelo kuwe:
