Nws Yog Qhov Zoo Uas Siv Lithium Hlau Phosphate Roj Teeb Rau Cov Tsheb Hluav Taws Xob Tshiab lossis Nickel-cobalt Roj Teeb?
Sep 21, 2020
Txhua tus neeg uas muaj kev nkag siab zoo txog cov tsheb hluav taws xob tshiab tam sim no paub tias qhov teeb meem loj tshaj plaws rau kev tsim kho lub zog hluav taws xob tshiab yog qhov nyuaj rau kev nce qib hauv cov roj teeb thev naus laus zis uas muaj roj teeb lub neej. Vim tias tus nqi tsim ntawm cov roj teeb hluav taws xob tshiab tseem nyob siab, feem ntau cov tsheb tshiab lub zog tsis tuaj yeem ua rau muaj kev vam meej ntawm lawv cov nqi siv roj tsawg, uas txwv rau lawv daim ntawv thov feem ntau thiab txo lawv cov kev sib tw piv rau cov roj tsheb ib txwm muaj. Cov tsoomfwv ntawm ntau lub tebchaws yuav tsum tau siv lub zog loj los pab txhawb nqa cov tsheb hluav taws xob tshiab.
Yog li no, qhov tseem ceeb ntawm kev tsim kho tshiab lub zog siv hluav taws xob roj rau cov cuab yeej hluav taws xob tshiab yog yuav luag sib luag rau qhov tseem ceeb ntawm lub cav thiab lub thawv rau cov roj tsheb hauv lub cev.
1. Lub zog tshiab tsheb roj teeb kev faib tawm
Ib hom yog lub zog cia roj teeb. Cov roj ntsha lithium peb nquag tham txog poob rau hauv pawg no. Ib hom yog roj teeb ntawm tes, uas siv Toyota Toyota Mirai. Muaj ntau hom roj teeb cia zog, xws li roj teeb lithium, roj teeb kua qaub-kua qaub, roj teeb sodium-leej faj thiab lwm yam.
Lithium roj teeb yog cov feem ntau siv. Ntawm lawv, lithium roj teeb raug faib ua ternary lithium roj teeb, lithium hlau phosphate roj teeb, lithium titanate roj teeb, thiab lwm yam Ternary lithium roj teeb tau siv dav hauv cov neeg caij tsheb vim lawv cov hluav taws xob muaj zog ntau. Cov neeg tsim khoom suav nrog Panasonic thiab LG txawv teb chaws, domestic Ningde era thiab BYD; lithium iron phosphate feem ntau siv rau hauv cov tsheb thauj neeg vim tias nws qhov kev nyab xeeb zoo, thiab tus tsim lub sawv cev yog BYD.
Lead-acid roj teeb yuav tsis siv roj teeb rau hauv tsheb. Vim tias lawv tsis yog phooj ywg ib puag ncig, lawv tau raug tshem tawm.
2. cov roj ntsha lithium hlau phosphate yog nrhiav tom qab
Tus nqi sib tw, kev nyab xeeb thiab tsis tshua muaj siab rau cov nqi khoom lag luam zoo ntawm lithium hlau phosphate roj teeb tau ua nws nrov dua hauv kuv lub teb chaws' s hluav taws xob tsheb lag luam.
BYD, kuv lub teb chaws loj tshaj plaws ua lub zog tsim hluav taws xob tshiab, qhia tias ib qho ntawm nws lub SUV tshiab yuav siv cov roj tsheb tshiab tsis muaj cov roj av tsis muaj roj nplua nuj nyob hauv ib nrab xyoo no. Lub tuam txhab tau tshaj tawm nyob rau hauv tsab ntawv tshaj tawm tias nws qhov tseeb SUV BYD Han yuav siv cov roj ntsha lithium iron phosphate roj teeb, uas tuaj yeem mus ntau dua 600 mais ib zaug, uas yog sib npaug rau kev tsav tsheb deb ntawm roj teeb nickel-cobalt.
Raws li cov lus ceeb toom, lithium iron phosphate battery yog 20% pheej yig dua li roj teeb nickel. Lithium iron phosphate battery cov cuab yeej siv tshuaj sib xyaw yog cov nqi pheej yig dua vim tias lawv cov kev sib txuas yooj yim thiab cov nqi qis ntawm cov khoom siv. Lwm cov roj teeb uas siv cov ntaub ntawv xws li nickel, manganese, aluminium, thiab cobalt yog cov ntau cov nyom, thiab tus nqi ntawm cov hlau no hloov ntau heev.
Kev rov qab los ntawm cov roj ntsha lithium iron phosphate roj teeb rau hauv lub tsheb hluav taws xob sab saum toj kuj tseem qhia tau tias raws li tsoomfwv thiab cov tuam txhab tsheb thoob ntiaj teb sib zog ntawm txoj kev mus rau lub tsheb hluav taws xob thoob ntiaj teb, kev txawj ntse roj teeb thiab cov kev txhawj xeeb ntawm cov neeg siv yog qhov deb ntawm kev hais daws.
Cov laj thawj vim li cas roj teeb nickel-cobalt tau txais kev pom zoo los ntawm cov khw yuav khoom yog tias lawv muaj lub roj teeb lub neej ntev ntawm cov nqi ib zaug xwb, uas daws cov teeb meem ntawm" deb kev ntxhov siab" rau cov neeg yuav khoom kom deb ntawm cov tsheb fais. Piv txwv, cov phiaj xwm roj teeb tshiab tsim los ntawm CATL thiab BYD tuaj yeem nce ntau ntawm cov tsheb hluav taws xob siv cov roj ntsha lithium iron phosphate roj, yog li txhim kho kev sib tw ntawm lithium iron phosphate battery thiab nickel-cobalt roj teeb.
3. nickel-cobalt roj teeb yog lub zoo tshaj plaws rau kev sib tw
Txawm li cas los xij, tib neeg yuav tsis siv sijhawm ntev siv roj teeb lithium iron phosphate battery. Raws li Morgan Stanley, lub sijhawm nruab nrab rau lub sijhawm nruab nrab rau cov roj ntsha lithium iron phosphate roj teeb yuav nce ntxiv, tab sis raws li roj teeb nickel-cobalt ua ntau dua, lithium iron phosphate battery yuav hloov thaum kawg. Nws tau kwv yees tias tus nqi ntawm roj teeb nickel-cobalt yuav nqis txog 20 hauv peb xyoos tom ntej no. %.
Raws li kev tshaj tawm xov xwm Reuters tau ua ntej lub hli no, txhawm rau txo nqi, Tesla yog sib tham ntxiv nrog Ningde SA ntawm kev muab cov roj ntsha lithium iron phosphate battery. Tesla tsis kam tawm tswv yim, thiab tus kws tshaj lij los ntawm Ningde Times tau hais tias:" Peb tuaj yeem muab peb cov neeg siv khoom muaj txiaj ntsig zoo thiab muaj kev sib tw."
Nws pom tau tias txawm nws yog ib qho ntawm ib qho ntawm tes los yog roj teeb lub pob, lub zog ntog tas li, thiab tus nqi ntawm lub roj teeb kuj poob sai. Yog li no, yav tom ntej, ntau ntawm cov tsheb hluav taws xob tshiab yuav nce ntxiv, thiab tus nqi yuav tseem poob. Qhov kev hem thawj ntawm kev sib tw rau roj tsheb yuav txuas ntxiv mus.
