Amabhethri e-Tesla amasha ashibhile ngenxa yokubambisana ne-CATL okokuqala ngqa e-China. Ngaphansi kuka-$80 kWh ngayinye ezingeni lephakheji?
Umlayezo oyimfihlo ovela kwaReuters. U-Tesla usebenzisana ne-CATL ukwethula ibhethri elisha le-lithium-ion eliguquliwe elishibhile e-China. Lokhu kubizwa ngokuthi “ibhethri lebhethri elingamakhilomitha ayizigidi ezingu-1,6,” kodwa ukwaziswa akukona ngempela lokho eliyikho.
Amaseli e-Tesla amasha = i-LiFePO4? I-NMC 532
Ngokusho kweReuters, "ibhethri lesigidi samamayela" elisha lizobiza futhi kufanele lihlale isikhathi eside. Ekuqaleni, amaseli kwakufanele enziwe yi-CATL yaseChina, kodwa uTesla ufuna ukuthuthukisa ubuchwepheshe ukuze kancane kancane - ngenxa yokunye ukuvuza - aqale ukukhiqiza kwawo.
I-Reuters ayinikezi noma yimiphi imininingwane mayelana namaseli, ngakho-ke singaqagela kuphela mayelana nokwakheka kwawo. Lokhu kungaba izakhi ze-lithium iron phosphate (LFP, LiFePO4), ehambisana kakhulu nezichasiso zombili ("shibhile", "ukuphila isikhathi eside"). Kungase futhi kube enye inguqulo yamaseli e-lithium-ion ane-NMC 532 (nickel-manganese-cobalt) ama-cathodes asuka kukristalu olulodwa:
> U-Tesla ufaka isicelo selungelo lobunikazi lamaseli amasha e-NMC. Izigidi zamakhilomitha zishayelwa kanye nokuwohloka okuncane
Lokhu kokugcina kungase kungabi "eshibhile" ngenxa yokuqukethwe kwe-cobalt ku-cathode (amaphesenti angu-20), kodwa ngubani owaziyo ukuthi uTesla uhlanganise ngokugcwele yonke into ekusetshenzisweni kwelungelo lobunikazi? Mhlawumbe okuhlukile kwe-NMC 721 noma 811 sekuhloliwe? ... Umkhiqizi ngokuqinisekile uyaziqhayisa ikhono lokufeza imijikelezo yokushaja emi-4.
Okokugcina, kungenzeka ukuthi lawa maseli e-CATL ayinguqulo ethuthukisiwe yalabo abakhona nge-NCA (Nickel-Cobalt-Aluminium) cathodes, equkethe ngaphansi kwamaphesenti angu-2018 e-cobalt kusukela okungenani ngo-3.
“Umthombo” ocashunwe yile nhlangano uthi inani lamanje lamaseli e-LiFePO4 ekhiqizwa yi-CATL - ngaphansi kwamadola angama-60 nge-1 kWh ngayinye... Ngalo lonke ibhethri, lokho kungaphansi kuka-$80 nge-kilowatt-hora. Kumaseli e-cobalt e-NMC aphansi, izindleko zebhethri zisondele ku-$ 100 / kWh.
Ngokusho kweReuters, izindleko zokukhiqiza amangqamuzana angaqondakali ziphansi kangangokuthi izimoto eziwagijimayo zingaqhathaniswa nenani lezimoto ezivuthayo zangaphakathi (umthombo). Kodwa futhi, imfihlakalo: ingabe sikhuluma ngokwamanani entengo e-Tesla ethengiswayo njengamanje? Noma mhlawumbe ezinye izinhlobo ezingaziwa zabakhiqizi? Kuyaziwa nje lokho amaseli azoqala ukuya e-China, futhi kancane kancane angase athulwe kwezinye izimakethe "ezimotweni ze-Tesla ezengeziwe.".
Singezwa okwengeziwe ngalokhu ngoSuku Lwebhethri, okumele lwenzeke engxenyeni yesibili kaMeyi.
> Usuku Lwebhethri ye-Tesla "lungaba maphakathi noMeyi." Kungenzeka…
Isithombe esivulayo: Iphakethe lebhethri le-Tesla Model S (c) elivela ku-Ted Dillard. Izixhumanisi ezintsha akudingeki zibe yi-cylindrical; zingahle zihlelwe ngezindlela ezahlukene.
Lokhu kungase kube nentshisekelo kuwe:
