Tesla lab ili ndi zinthu zomwe zimatha kupirira mamiliyoni a kilomita.
Laboratory yofufuza yomwe Tesla adalemba kuti azigwira ntchito pama cell a lithiamu-ion adadzitamandira ndi chemistry yatsopano. Chifukwa cha cathode ya NMC (nickel-manganese-cobalt) ndi electrolyte yatsopano, akuyenera kupirira ma kilomita 1,6 miliyoni agalimoto yamagalimoto.
Pakalipano, ambiri a dziko la magalimoto amagwiritsa ntchito mitundu yosiyanasiyana ya maselo a NMC, pamene Tesla amagwiritsa ntchito kusakaniza kosiyana pang'ono kwa zinthu: NCA (nickel-cobalt-aluminium). Mabatire amakono a Tesla akuyenera kupirira ma kilomita 480 mpaka 800. Komabe, Elon Musk akufuna kuonetsetsa kuti kuwonongeka kwawo kukucheperachepera kawiri, kuti athe kupirira monga magiya ndi matupi - mpaka makilomita 1,6 miliyoni a mileage.
Monga tafotokozera ndi portal Electrek (gwero), labotale ya Jeff Dahn, yomwe imafufuza mwayi wowongolera ma cell a Li-ion a Tesla, idapereka zotsatira za ntchito yake. Maselo atsopanowa amagwiritsa ntchito "crystal crystal" cathode NMC 532 ndi electrolyte yapamwamba. Pambuyo poyesedwa, zomwe nthawi zina zimatha mpaka zaka zitatu. asayansi adayika pachiwopsezo chonena kuti ma cell atha kupirira mpaka ma kilomita 1,6 miliyoni mgalimoto. kapena zaka zosachepera makumi awiri m'sitolo yamagetsi.
Ngakhale ndi kutentha kwa ma cell kumatenthetsa mpaka madigiri 40, adasunga 70 peresenti yamphamvu pambuyo pa milandu 3 yonse, zomwe ziyenera kumasulira mtunda wa makilomita pafupifupi 1,2 miliyoni. Pamene kusunga kutentha kwa madigiri 20 pambuyo pa mtunda wa makilomita pafupifupi 3 miliyoni mphamvu ya maselo ayenera kutsika pafupifupi 90 peresenti ya mphamvu zoyambirira.
> Tesla akufuna kupanga mpaka 1 GWh ya maselo pachaka. Tsopano: 000 GWh, nthawi 28 zochepa
Pakuyesa kofananako, ma cell a lithiamu-ion omwe amapezeka pamalonda amatha kupirira kuzungulira kwa 1, komwe kumayenera kumasulira kukhala ma kilomita 000 amtunda. Ngakhale ziyenera kuwonjezeredwa apa kuti ma cell omwe amagwiritsidwa ntchito pamakampani amagalimoto amakhala ndi zosakaniza zosiyanasiyana za ma electrolyte, ntchito yayikulu yomwe ndikuchepetsa kuwononga:
Ndikoyenera kuwerenga (gwero), chifukwa ntchitoyi imakonza chidziwitso cha maselo a lithiamu-ion ndikuwonetsa kupita patsogolo komwe kwachitika zaka 4-6 zapitazi:
Chithunzi chotsegulira: A) chithunzi cha microscopic cha NMC 532 powder B) chithunzi chochepa kwambiri cha electrode pamwamba pambuyo pa kuponderezedwa, C) imodzi mwa maselo a 402035 oyesedwa m'matumba pafupi ndi ndalama za dollar ziwiri za Canada, PASI, chithunzi kumanzere) kuwonongeka za ma cell oyesedwa motsutsana ndi ma cell achitsanzo, PASI, chithunzi kumanja) moyo wa cell kutengera kutentha panthawi yolipira (c) Jessie E.
