U-Tesla ufaka ilungelo lobunikazi lamaseli amasha e-NMC. Izigidi zamakhilomitha kanye nokucekelwa phansi okuncane

I-Tesla Canada ifake isicelo samaseli amasha nge-NMC (nickel-manganese-cobalt) cathodes. Lezi zibonakala ziyizinto ezifanayo nalezo elebhu ka-Jeff Dan ezakhelwe umenzi ezivumela izigidi zamamayela ukuthi zimbozwe ngokuguga okuncane.

I-Tesla izoshintsha isuka ku-NCA iye ku-NMC?

Njengamanje, i-Tesla isebenzisa amangqamuzana e-lithium-ion ane-NCA cathodes, okungukuthi, i-nickel-cobalt-aluminium, enokuqukethwe kwe-cobalt engaphansi kwamaphesenti angu-10, okungenani ku-Tesla Model 3. Lokhu kuyisimo ngokwayo, ngoba yesimanje engcono kakhulu. amaseli anama-cathodes e-NMC811 ahlanganisa amaphesenti angu-10 e-cobalt asetshenziswa - kodwa aqala ukusebenza kancane, asusa izakhi ze-NMC622.

> Amaseli angu-2170 (21700) kumabhethri e-Tesla 3 angcono kune-NMC 811 ku-_future_

Njengoba u-Elon Musk athembisa, I-Tesla yesimanje kufanele ihambe isuka kumakhilomitha ayi-0,48 iye ku-0,8 million ngebhethri. Nokho, esikhathini esizayo esiseduze, angathanda ukuzuza amakhilomitha ayizigidi ezingu-1,6 ngamandla ebhethri, into okufanele isekelwe yi-Tesla Model 3 nomzimba we-powertrain.

Futhi lapha usizwa impumelelo yelabhorethri kaJeff Dan, esebenzele uTesla isikhashana futhi okwathi ngoSepthemba 2019 yaziqhenya ngekhemikhali entsha ye-electrolyte yamaseli e-lithium-ion ane-NMC532 cathodes.

Ngenxa yokusetshenziswa kwe-cathode "ye-crystal eyodwa" kanye ne-electrolyte enezithasiselo ezisetshenziswa njengamanje ezinothiswe ku-dioxazolones kanye ne-sulfite ester nitriles, kuye ngokwakheka kwe-electrolyte (umthombo), okulandelayo kufinyelelwe:

ukuwohloka kancane kwamaseli ngenxa yokuvinjelwa ukukhula kongqimba oludlulayo (SEI) olubopha ama-ion e-lithium, abhekele ngqo amandla,
ukusebenza kahle kwamaseli njengomsebenzi wokushisa.

A) Isithombe esincane se-NMC 532 powder B) Isithombe esincane se-electrode surface ngemva kokucindezelwa, C) Elinye lamaseli ahloliwe we-402035 esikhwameni eduze kohlamvu lwemali lwamadola amabili aseCanada, i-BOTTOM, umdwebo ongakwesokunxele) ukuchithwa kwamaseli okuhlola uma kuqhathaniswa ngemuva kwamaseli emodeli, BOTTOM. umdwebo ongakwesokudla) impilo yeseli ngokumelene nezinga lokushisa ngesikhathi sokushaja (c) Jesse E. Harlow et al. / Ijenali ye-Electrochemical Society

Konke kuzwakala kuyinkimbinkimbi, kodwa imiphumela iyamangalisa:

umthamo wamaphesenti angu-70 ngemva kwemijikelezo yokushaja emi-3 ku-650 degrees (cishe amakhilomitha ayizigidi ezingu-40),
amandla afinyelela kumaphesenti angama-90 ngemuva kwamakhilomitha ayizigidi ezi-3uma izinga lokushisa leseli ligcinwe ku-20 degrees Celsius futhi ukushaja kwenziwa ku-1 ° C (umthamo webhethri 1x, okungukuthi 40 kW nebhethri engu-40 kWh, i-100 kW nebhethri engu-100 kWh, njll.).

Akwaziwa ukuthi isicelo selungelo lobunikazi esifakiwe sisho ukuthi uTesla uzodlulisela i-NCA ku-NCM. Kuze kube manje, sekushiwo ngokungafanele ukuthi amaseli e-NCM lithium-ion kufanele avele kumamodeli enziwe eChina.

> I-Asphalt (!) Izokwandisa umthamo futhi isheshise ukushajwa kwamabhethri e-lithium-ion.

Kodwa-ke, singasho ngokuqinisekile ukuthi umkhiqizi waseCalifornian usekulungele ukunikeza amalungelo akhe obunikazi. Ngokushicilela umsebenzi wezithasiselo ezintsha ze-electrolyte, angase afune ukusheshisa umsebenzi womhlaba kumaseli e-lithium esizukulwane esilandelayo.

Nasi isicelo esigcwele se-patent ye-Tesla (landa i-PDF LAPHA):

Inothi Lomhleli www.elektrowoz.pl: Ngenkathi sithuthukisa le timu, sibe nomuzwa wokuthi ukwakhiwa kwemoto kagesi yasePoland kuzobiza KAKHULU KAKHULU. Asikwazanga ukuthola noma yikuphi okushiwo nge-dioxazolones ne-sulphite ester nitriles ku-inthanethi yesi-Polish. Lokhu kusho ukuthi cishe akekho umuntu e-Poland ongaqonda lolu hlelo lokusebenza lwelungelo lobunikazi neziphetho zalo. Sinama-PhD amaningi ngokubhala, ukumaketha, i-philology, nomlando, kodwa inqubekelaphambili yangempela yenzeka kwenye indawo, khona lapha, phambi kwamehlo ethu.

Lokhu kungase kube nentshisekelo kuwe:
