Cobalt yog hlau siv hauv ntau lub tsheb roj teeb. Cov xov xwm yog TESLA no yuav siv "cobalt-dawb" roj teeb, tab sis dab tsi "cov peev txheej" yog cobalt? Kuv yuav nthuav tawm los ntawm cov kev paub yooj yim uas koj xav paub.
Nws lub npe yog teeb meem cov zaub mov muab tau los ntawm dab
Koj puas paub lub caij cobalt? Tsis tsuas yog muaj nyob rau hauv cov roj teeb ntawm cov hluav taws xob tsheb (EVS) thiab cov tshuab ntxhua khaub ncaws xws li cov neeg hais lus, thiab, cov hlau nplaum rau cov neeg hais lus, thiab, kuj ceeb tias, roj ntxiv. Cobalt yog muaj npe tom qab "kobold," tus dab uas nquag tshwm nyob rau hauv qhov chaw tseeb scenieval, thiab tau ntseeg nyob rau hauv cov mines los tsim cov mines thiab lom neeg. Yog lawm.
Tam sim no, txawm hais tias tsis muaj dab nyob rau hauv kuv li, cobalt yog lom thiab tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv xws li pneumoconiosis yog tias koj tsis hnav cov khoom siv tiv thaiv kev tiv thaiv kev mob nkeeg. Thiab txawm hais tias cov koom pheej ywj pheej ntawm cov Congo ua ntau dua ib nrab ntawm cov neeg txom nyem me (artisanal mine nrog cov cuab yeej yooj yim yam tsis muaj kev nyab xeeb kev cob qhia. ), Collapse kev huam yuaj tshwm sim ntau zaus, cov menyuam yaus yuam kom ua haujlwm ntev nrog 200 yen ib pawg, thiab txawm tias yog ib pab kub, yog li cov kub, tungsten, tinsten, tin, thiab tungstum. , Tau hu ua kev tsis sib haum xeeb minerals.
Txawm li cas los xij, nrog txoj kev sib kis ntawm Evs thiab Lithium-ion roj teeb, nyob rau hauv cov tuam txhab thoob ntiaj teb txawm tias muaj cov khoom siv tsis ntev los no, suav nrog cov khoom siv tsis txaus ntseeg, suav nrog cov khoom siv tsis txaus ntseeg
Piv txwv li, roj teeb Giants Catl thiab LG Chem yog koom nrog Suav-coj "lub luag haujlwm cobal teg num (RCI)", feem ntau ua haujlwm los rhuav tshem menyuam yaus ua haujlwm.
Nyob rau hauv 2018, Fairalt Alliance (FCA), Cobalt Fair Compangies, tau tsim los ua ib qho kev pib ua kom txhawb nqa cov txheej txheem cobalvalt. Cov neeg koom nrog ntsuas tesla, uas tau noj cov roj teeb lithium-ion
Saib ntawm Nyij Pooj, Sumitomo Hlau Mining Co., Ltd. Hauv qab.
Nyob rau yav tom ntej, raws li cov tuam txhab loj yuav tau tua kom muaj kev tswj hwm kom muaj kev pheej hmoo thiab dhia dej rau hauv cov mines me me, thiab thov kom maj mam poob.
Pom tseeb tsis muaj kev cobalt
Tam sim no, tus naj npawb ntawm Evs tseem me, muaj tag nrho ntawm 7 lab, suav nrog cov khoom siv hluav taws xob hauv ntiaj teb
Tag nrho cov nyiaj ntawm kev cobalt siv hauv cov roj teeb ntawm 2019 yog 19,000 tons, uas txhais tau tias qhov nruab nrab ntawm 9 kg ntawm kev cobalt yog xav tau ib lub tsheb. Ua 1 Cillion Evs nrog 9 kg txhua qhov yuav tsum tau cobalt, tab sis lub ntiaj teb tons, thiab hais thaum pib, 100,000 tons hauv lwm yam kev lag luam txhua txhua xyoo. Vim nws yog tus hlau uas siv ntau heev, nws yog pom tau zoo li nws yog.
EP kev muag khoom yuav tsum loj hlob tenfold hauv 2025, nrog Tonnes, suav nrog cov roj teeb tshwj xeeb thiab lwm yam kev siv. Txawm hais tias EV thov cov qib tawm, nws yuav khiav tawm ntawm txhua yam tam sim no muaj peev xwm nyob rau hauv 30 xyoo.
Tawm tsam cov keeb kwm yav dhau los, roj teeb tsim tawm ua haujlwm nyuaj hnub thiab hmo ntuj txog yuav ua li cas txo qis dua cobalt. For example, NMC batteries using nickel, manganese, and cobalt are being improved by NMC111 (nickel, manganese, and cobalt are 1: 1. The amount of cobalt has been steadily reduced from 1: 1) to NMC532 and NMC811, and NMC9.5.5 (cobalt ratio is 0.5) is currently under development.
NCA (Nickel, cobalt, Txhuas) Siv los ntawm tesla muaj cov ntsiab lus cobal txiav tawm mus rau Suav Tebchaws Suav Teb Roj Teeb (LFP). Tseem muaj cov qib uas tau saws. Txawm hais tias LFP yog qis dua rau NCA nyob rau hauv cov nqe lus ntawm kev ua tau zoo, nws muaj cov yam ntxwv ntawm cov ntaub ntawv pheej yig, cov khoom siv khov, thiab lub neej ntev.
Thiab ntawm "Tesla roj teeb hnub" tau teem sijhawm thaum 6:30 teev sawv ntxov rau lub Cuaj Hlis 23, 2020 nyob rau hauv Suav teb, thiab nws yuav pib pawg ntau lawm nrog panasonic hauv ob peb xyoos. Yuav tsum tau.
Los ntawm txoj kev, hauv Nyiv, "Feem ntau cov hlau" thiab "cov av tsis tshua muaj" feem ntau tsis meej pem. Cov hlau tsis tshua muaj siv nyob rau hauv kev lag luam vim tias "kev nyab xeeb yog qhov tseem ceeb ntawm lub ntiaj teb uas muaj kev nplua nuj los ntawm kev lag luam thiab kev lag luam (Ministry of Economy, Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam thiab Kev Lag Luam Nws yog cov hlau uas tsis yog-kab uas feem ntau siv, thiab yog ib lo lus dav dav rau cov lus lithium, titrorium, chromalle, platinum, thiab cov av tsis tshua muaj. Ntawm cov no, tsis tshua muaj lub ntiaj teb, thiab 17 hom tsiaj xws li neodymium thiab dysposium siv rau cov hlau nplaum yog txhais.
Ntawm keeb kwm ntawm qhov tsis muaj cov cobalt cov peev txheej, cobalt hlau ntawv & hmoov, thiab cobalt chloride xws li cobalt chloride txawm tias Hexaammobalt (III) Chloride yog luv.
Lub luag hauj lwm tawg los ntawm cobalt
Raws li qhov kev ua tau zoo yuav tsum tau rau EVS nce, nws cia siab tias cov roj teeb, zoo li muaj cov roj teeb-accidfur, yog li cov hmoov av uas tsis xav tias cov peev txheej yuav daig. Txawm li cas los xij, qhov ntawd txhais tau tias qhov kev thov rau kev cob lub zog collapse qee qhov chaw.
Qhov kev hloov pauv yuav tuaj nyob rau hauv 5 mus rau 10 xyoo ntawm qhov ntxov tshaj plaws, thiab cov tuam txhab me me tsis kam txais kev nqis peev ntev hauv kev cog lus. Txawm li cas los xij, vim tias peb tab tom pom qhov kawg, peb xav tau cov miners hauv zos kom tawm ib puag ncig kev ua haujlwm zoo dua li ua npuas.
Thiab cov roj teeb hluav taws xob tam sim no ntawm kev ua lag luam tseem yuav tsum tau siv sijhawm tom qab lawv tau ua tiav lawv cov haujlwm 10 txog 20 xyoo tom qab, tus thawj coj ntawm lub xov tooj cua JB yav dhau los JB Strobel. -Muaj nyiaj thiab lwm tus tau tsim tsa Cobalt rov qab thev naus laus zis thiab yuav rov siv nws nrog lwm cov peev txheej.
Txawm hais tias qhov kev thov rau qee cov khoom siv ib ntus nce mus nyob hauv cov txheej txheem hluav taws xob, peb yuav tsis kam yuav qhov kev npau taws ntawm kobolts lurking hauv lub qhov tsua. Kuv xav xaus zaj dab neeg no nrog kev cia siab ntawm kev ua ib haiv neeg.
