Lub chaw soj ntsuam kev tshawb fawb koom tes nrog Tesla tau patented tshiab roj teeb hlwb. Nws yuav tsum ceev, zoo dua thiab pheej yig dua.
NSERC / Tesla Canada Kev Tshawb Fawb Kev Tshawb Fawb Kev Tshawb Fawb Kev Tshawb Fawb Thov rau Patent ib tug tshiab muaj pes tsawg leeg ntawm hluav taws xob hlwb, tsim los ntawm nws. Ua tsaug rau cov tshuaj muaj pes tsawg leeg ntawm cov electrolyte tshiab, cov hlwb tuaj yeem raug them thiab tawm sai dua thiab tib lub sijhawm yuav tsum decompose qeeb dua.
Tus tshiab cell chemistry yog tsim los ntawm pab pawg ntawm Jeff Dahn, nws lub chaw kuaj mob tau ua haujlwm rau Tesla txij li xyoo 2016. Cov patent yog hais txog cov roj teeb tshiab uas siv cov electrolytes nrog ob qho ntxiv. Nws yog tsim nyog ntxiv ntawm no tias txawm hais tias qhov yooj yim muaj pes tsawg leeg ntawm electrolyte ntawm lithium-ion hlwb paub, qhov tseeb nws yog. Txhua lub xov tooj ntawm tes manufacturers siv ntau yam khoom siv los txo tus nqi ntawm kev degradation ntawm lub tshuab thaum them thiab tawm..
Cov naj npawb tsis muaj nyob rau hauv pej xeem, tab sis cov kws tshawb fawb ntawm tes hais tias cov tuam txhab roj teeb tau siv cov khoom sib xyaw ntawm ob, peb, lossis tsib cov tshuaj ntxiv kom qeeb cov txheej txheem tsis zoo uas ua rau cov roj teeb poob qis.
> Volkswagen xav ua kom MEB platform muaj rau lwm cov tuam ntxhab. Puas yuav Ford thawj?
Dahn txoj hauv kev txo tus naj npawb ntawm kev ntxiv rau ob, uas hauv nws tus kheej txo cov nqi tsim khoom. Tus kws tshawb fawb tau thov tias cov tshuaj muaj pes tsawg leeg tsim los ntawm nws tuaj yeem siv rau hauv NMC hlwb, uas yog, nrog cathodes (zoo electrodes) uas muaj cov nickel-manganese-cobalt, thiab qhov no yuav ua rau lawv cov kev ua tau zoo, yuav ua rau kom them nqi thiab ua kom qeeb. aging txheej txheem (qhov chaw).
NMC hlwb siv los ntawm ntau lub tuam txhab tsheb, tab sis tsis yog Tesla, uas siv NCA (Nickel-Cobalt-Aluminium) hlwb hauv tsheb, thiab NMC variant tsuas yog ntsia rau hauv lub zog cia khoom.
Nco qab tias thaum Lub Rau Hli 2018, thaum lub rooj sib tham nrog Tesla cov tswv lag luam, Elon Musk tau hais tias nws pom txoj hauv kev los ua kom cov roj teeb muaj peev xwm nce 30-40 feem pua tsis tas yuav nce ntxiv. Qhov no yuav tshwm sim hauv 2-3 xyoos. Nws tsis paub tias qhov no yog vim kev tshawb fawb ntawm NSERC lossis rau daim ntawv thov patent uas tau hais tseg (saib kab lus saum toj no: NCM vs NCA).
Txawm li cas los xij, nws yooj yim los xam qhov ntawd Tesle S thiab X, tsim nyob rau hauv 2021, yuav tsum muab 130 kWh pob, tso cai rau lawv mus 620-700 kilometers ntawm ib tug nqi..
Cov lus piav qhia ntxaws ntxaws ntawm patent thiab ntxiv tuaj yeem pom ntawm Scribd portal NO.
