Tsav los ntawm lub ntiaj teb "carbon neutrality" lub hom phiaj, lub zog tshiab tsheb kev lag luam yog booming ntawm qhov xav tsis thoob. Raws li "lub plawv" ntawm lub zog tshiab tsheb,lithium roj teebtau ua ib qho kev pab txhawb tsis tau. Nrog nws lub zog siab ceev thiab lub neej voj voog ntev, nws tau dhau los ua lub cav muaj zog rau lub kiv puag ncig kev thauj mus los ntsuab no. Ib yam li ob sab ntawm ib npib, txhua yam muaj ob sab. Thaum cov roj teeb lithium coj peb lub zog huv thiab muaj txiaj ntsig, lawv kuj tau nrog cov teeb meem uas tsis tuaj yeem tsis quav ntsej - qhov pov tseg ntawm cov roj teeb lithium pov tseg.
Cov teeb meem lithium roj teeb pov tseg
Xav txog tias cov tsheb tshiab muaj zog tau kaw los ntawm txoj kev hauv nroog. Lawv nyob ntsiag to thiab ib puag ncig tus phooj ywg, thiab lawv pleev xim rau daim duab zoo nkauj ntawm kev mus ncig yav tom ntej rau peb. Tab sis thaum cov tsheb no tau ua tiav lawv txoj haujlwm, yuav ua li cas rau lawv "lub siab" - lublithium roj teeb? Cov ntaub ntawv qhia tau hais tias los ntawm 2025, Tuam Tshoj cov roj teeb hluav taws xob so haujlwm yuav tsum ncav cuag 1,100 GWh, sib npaug rau lub zog tsim hluav taws xob txhua xyoo ntawm tsib lub zog hluav taws xob Peb Gorges. Xws li tus lej loj, yog tias tsis ua haujlwm kom raug, yuav ua rau muaj kev kub ntxhov rau ib puag ncig thiab cov peev txheej.
Cov roj teeb lithium pov tseg muaj ntau cov khoom siv hlau zoo xws li lithium, cobalt, thiab npib tsib xee. Yog tias peb tso cai rau lawv ploj, nws yuav ua rau muaj kev tso tseg "lub nroog mines". Dab tsi yog qhov txhawj xeeb tshaj yog tias cov roj teeb lithium pov tseg kuj muaj cov khoom tsis zoo xws li electrolytes thiab cov hlau hnyav. Yog tias lawv tsis ua haujlwm zoo, lawv yuav ua rau muaj kuab paug loj rau cov av, cov dej hauv av, thiab cov huab cua, thiab tseem ua rau tib neeg kev noj qab haus huv.
Tau ntsib cov teeb meem uas coj los ntawm cov roj teeb lithium pov tseg, peb tsis tuaj yeem zaum ntawm qhov chaw, thiab peb tsis tuaj yeem ntshai cov roj teeb. Hloov chaw, peb yuav tsum nquag nrhiav kev daws teeb meem, tig "kev phom sij" mus rau "lub cib fim", thiab pib rau txoj hauv kev ntawm kev txhim kho kom ruaj khov nrog cov voj voog ntsuab. Hmoov zoo, kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tau taw qhia cov kev taw qhia rau peb. Lub kiv puag ncig ntsuab uas tau tsav los ntawm kev tsim kho thev naus laus zis tau tshwm sim ntsiag to, ua rau muaj kev cia siab tshiab rau "rov yug dua tshiab" ntawm cov roj teeb lithium pov tseg.
Lithium roj teeb ntsuab kiv puag ncig, tig pov tseg rau hauv cov khoom muaj nqis
Hauv kev hloov pauv ntsuab no, ntau yam thev naus laus zis thiab khoom siv tau tshwm sim. Lawv zoo li tej yam yees siv "alchemists" uas rov rho tawm cov peev txheej tseem ceeb los ntawm cov roj teeb lithium pov tseg, tig lawv mus rau hauv cov khoom muaj nqis thiab txhawb nqa lawv.
Cia peb taug kev mus rau hauv "lub Hoobkas disassembly" ntawm pov tseglithium roj teeb. Ntawm no, lithium roj teeb crushing thiab sorting khoom yog zoo li ib tug kws "surgeon". Lawv tuaj yeem raug tshem tawm thiab faib cov roj teeb lithium pov tseg, cais cov khoom siv roj teeb sib txawv, thiab tsim lub hauv paus rau kev rov ua dua tshiab thiab ua tiav.
Tom qab ntawd, cov khoom siv roj teeb cais no yuav nkag mus rau "kev cob qhia" sib txawv rau kev ua haujlwm sib cais. Cov khoom siv hluav taws xob zoo uas muaj cov hlau xws li lithium, cobalt, thiab npib tsib xee yuav raug xa mus rau "kev cob qhia hlau rho tawm". Los ntawm hydrometallurgy, pyrometallurgy thiab lwm yam txheej txheem, cov hlau tseem ceeb no yuav raug muab rho tawm rau kev tsim cov roj teeb lithium tshiab lossis lwm yam khoom.
Cov khoom siv roj teeb uas muaj cov khoom tsis zoo xws li electrolytes thiab cov hlau hnyav yuav raug xa mus rau qhov tshwj xeeb "rhiav kev kho ib puag ncig", uas lawv yuav dhau los ntawm cov txheej txheem kev kho mob nruj heev kom ntseeg tau tias cov khoom tsis zoo muaj kev nyab xeeb thiab zoo pov tseg yam tsis muaj kuab paug rau lub cev. ib puag ncig
Nws tsim nyog hais tias nyob rau hauv cov txheej txheem rov ua dua ntawm cov roj teeb lithium pov tseg, kev tiv thaiv ib puag ncig yog qhov tseem ceeb tshaj plaws. Yuav kom txo qis ib puag ncig muaj kuab paug, ntau lub tuam txhab tau txais kev tiv thaiv kev tiv thaiv ib puag ncig thiab cov cuab yeej siv, xws li cov khoom siv pov tseg lithium roj teeb dissociation ntse ub no cov cuab yeej siv.
Cov cuab yeej no zoo ib yam li cov tub rog tag nrho "kev tiv thaiv ib puag ncig". Nws koom nrog ntau yam kev tiv thaiv xws li kev sib khi tshuab thiab cov tshuab ua kom huv, uas tuaj yeem tiv thaiv cov pa tawm thiab cov dej khib nyiab pov tseg, kom ntseeg tau tias tag nrho cov txheej txheem rov ua dua tshiab yog ntsuab, ib puag ncig zoo thiab nyab xeeb.
Cov txiaj ntsig kev lag luam ntawm kev rov ua dua lithium roj teeb
Qee lub tuam txhab tseem tab tom tshawb nrhiav ntau lub zog-txuag thiab ib puag ncig tus phooj ywg cov txheej txheem rov ua dua tshiab, xws li cov txheej txheem tshiab ntawm "kub kub volatilization + electrolyte cryogenic recycling ua ke". Cov txheej txheem no zoo li "tus neeg saib xyuas hauv tsev", uas tuaj yeem txo tus nqi ntawm lithium roj teeb rov ua dua tshiab. kev siv hluav taws xob thiab cov pa roj carbon emissions, thiab sib koom ua ke lub tswv yim ntawm kev txuag hluav taws xob thiab txo qis emission rau hauv txhua qhov txuas
Nrog rau kev nce qib txuas ntxiv thiab kev siv thev naus laus zis, kev ua haujlwm rov ua dua tshiab thiab kev tiv thaiv ib puag ncig ntawm cov roj teeb lithium tau raug txhim kho, ua rau muaj txiaj ntsig zoo rau kev rov ua dua tshiab thiab kev tiv thaiv ib puag ncig.
Recycling ntawm kev sivlithium roj teebtsis yog tsuas yog ib qho kev tiv thaiv ib puag ncig nkaus xwb, tab sis kuj tseem muaj txiaj ntsig kev lag luam loj. Cov lithium, cobalt, npib tsib xee thiab lwm yam hlau muab rho tawm los ntawm cov roj teeb lithium siv tau zoo li cov khoom muaj nqis pw tsaug zog. Thaum sawv ntxov, Tau txais nws cov luster thiab tsim cov txiaj ntsig kev lag luam ntau heev.
Tsis tas li ntawd, kev tsim kho thev naus laus zis kuj tseem yog lub cav tseem ceeb los txhawb txoj kev loj hlob ntawm cov khib nyiab lithium roj teeb rov ua lag luam. Tsuas yog los ntawm kev cuam tshuam tas li los ntawm cov kev tsis sib haum xeeb thiab kev txhim kho kev ua haujlwm rov ua dua tshiab thiab kev siv cov peev txheej tuaj yeem daws cov teeb meem ib puag ncig los ntawm cov roj teeb lithium pov tseg thiab ua tiav txoj kev loj hlob ntawm kev lag luam.
Txog rau qhov kawg no, ntau lub tuam txhab thiab cov chaw tshawb fawb tshawb fawb tau nce lawv cov peev txheej R & D thiab nquag tshawb nrhiav cov thev naus laus zis tshiab thiab cov txheej txheem, thiab tau ua ntau txoj hauv kev. Qee lub tuam txhab tau tsim cov khoom siv hluav taws xob disassembly ntau dua uas tuaj yeem ua kom tiav cov khoom pov tseg ntawm cov roj teeb lithium ntau dua thiab nyab xeeb; qee lub tsev tshawb fawb tshawb fawb tau cog lus los txhim kho ib puag ncig tus phooj ywg thiab siv tau zoo hlau rho tawm thev naus laus zis, siv zog los txhim kho cov hlau rov qab thiab txo cov pa phem ib puag ncig.
Xaus
Kev rov ua dua tshiab ntawm cov roj teeb lithium siv tsis yog tsuas yog lub luag haujlwm ntawm cov tuam txhab thiab tsoomfwv, tab sis kuj yuav tsum muaj kev koom tes ntawm tag nrho cov zej zog. Raws li cov neeg siv khoom zoo tib yam, peb tuaj yeem pib los ntawm peb tus kheej thiab koom nrog hauv kev rov ua dua tshiab ntawm cov roj teeb lithium los pab txhawb kev tiv thaiv ib puag ncig.
Peb tuaj yeem xaiv xa cov xov tooj ntawm tes, khoos phis tawj thiab lwm yam khoom siv hluav taws xob mus rau cov khoom siv hluav taws xob tsis tu ncua es tsis txhob muab pov tseg ntawm qhov xav tau; thaum yuav cov tsheb fais fab tshiab, peb tuaj yeem muab qhov tseem ceeb rau cov hom lag luam uas muab cov kev pab cuam rov siv roj teeb; peb yuav tsum nquag txhawb qhov tseem ceeb ntawm kev rov ua dua cov roj teeb lithium thiab txhawb kom ntau tus neeg koom nrog qhov kev tiv thaiv ib puag ncig.
Recycling ntawm kev sivlithium roj teebyog ib txoj haujlwm ntev thiab nyuaj, tab sis peb muaj laj thawj ntseeg tias nrog kev sib koom tes ntawm tsoomfwv, kev lag luam thiab tag nrho cov haujlwm hauv zej zog, peb yuav muaj peev xwm pib rau txoj kev loj hlob ntsuab thiab muaj txiaj ntsig, yog li cov roj teeb lithium siv yuav tsis muaj. ntev dhau los ua lub nra hnyav rau ib puag ncig, tab sis dhau los ua cov peev txheej muaj txiaj ntsig thiab pab txhawb kev tsim kho lub ntiaj teb zoo nkauj.
Yog tias koj muaj lus nug lossis xav paub ntxiv, thov tsis txhob yighu rau peb.
