Kev Taw Qhia:
Raws li lub hom phiaj thoob ntiaj teb "carbon neutrality", kev lag luam tsheb fais fab tshiab tab tom loj hlob sai heev. Raws li "lub plawv" ntawm cov tsheb fais fab tshiab,roj teeb lithiumtau ua ib qho kev pab cuam uas tsis muaj qhov kawg. Nrog nws lub zog ceev ceev thiab lub neej ntev, nws tau dhau los ua lub cav muaj zog rau qhov kev hloov pauv kev thauj mus los ntsuab no. Ib yam li ob sab ntawm lub npib, txhua yam muaj ob sab. Thaum cov roj teeb lithium coj peb lub zog huv thiab siv tau zoo, lawv kuj muaj teeb meem uas tsis tuaj yeem tsis quav ntsej - kev pov tseg cov roj teeb lithium pov tseg.
Kev kub ntxhov ntawm cov roj teeb lithium pov tseg
Xav txog seb cov tsheb fais fab tshiab tab tom khiav hla txoj kev hauv nroog. Lawv nyob ntsiag to thiab zoo rau ib puag ncig, thiab lawv kos duab zoo nkauj ntawm kev mus ncig yav tom ntej rau peb. Tab sis thaum cov tsheb no ua tiav lawv txoj haujlwm, yuav muaj dab tsi tshwm sim rau lawv "lub siab" - lubroj teeb lithiumCov ntaub ntawv qhia tau tias txog xyoo 2025, cov roj teeb fais fab hauv Suav teb uas so haujlwm lawm yuav nce mus txog 1,100 GWh, sib npaug rau kev tsim hluav taws xob txhua xyoo ntawm tsib lub chaw tsim hluav taws xob Three Gorges. Tus lej loj heev no, yog tias tsis siv kom zoo, yuav ua rau muaj kev nyuaj siab loj heev rau ib puag ncig thiab cov peev txheej.
Cov roj teeb lithium pov tseg muaj ntau yam hlau muaj nqis xws li lithium, cobalt, thiab nickel. Yog tias peb cia lawv ploj mus, nws yuav zoo li tso tseg "cov chaw khawb av hauv nroog". Qhov txhawj xeeb ntxiv yog tias cov roj teeb lithium pov tseg kuj muaj cov tshuaj lom xws li electrolytes thiab cov hlau hnyav. Yog tias lawv tsis raug tswj hwm kom zoo, lawv yuav ua rau muaj kuab paug loj rau cov av, cov dej, thiab huab cua, thiab txawm tias hem tib neeg txoj kev noj qab haus huv.
Thaum ntsib cov teeb meem uas cov roj teeb lithium pov tseg coj los, peb tsis tuaj yeem zaum ntsiag to, thiab peb tsis tuaj yeem ntshai cov roj teeb. Hloov chaw, peb yuav tsum nrhiav kev daws teeb meem, hloov "kev phom sij" mus ua "lub cib fim", thiab pib txoj kev loj hlob ruaj khov nrog cov voj voog ntsuab. Hmoov zoo, kev nce qib ntawm kev tshawb fawb thiab thev naus laus zis tau taw qhia qhov kev taw qhia rau peb. Kev hloov pauv ntsuab uas tsav los ntawm kev tsim kho tshiab thev naus laus zis tau tshwm sim ntsiag to, coj kev cia siab tshiab rau "kev yug dua tshiab" ntawm cov roj teeb lithium pov tseg.
Kev hloov pauv ntsuab ntawm lub roj teeb lithium, tig cov khib nyiab mus ua khoom muaj nqis
Hauv qhov kev hloov pauv ntsuab no, ntau yam thev naus laus zis thiab khoom siv siab heev tau tshwm sim. Lawv zoo li cov "alchemists" uas rov rho tawm cov peev txheej muaj nqis los ntawm cov roj teeb lithium pov tseg, hloov lawv mus ua cov khoom muaj nqis thiab ua kom lawv rov muaj zog.
Cia peb taug kev mus rau hauv "lub Hoobkas rhuav tshem" ntawm cov khib nyiabroj teeb lithiumNtawm no, cov khoom siv zom thiab cais cov roj teeb lithium zoo li "kws phais neeg" uas muaj kev txawj ntse. Lawv tuaj yeem rhuav tshem thiab faib cov roj teeb lithium pov tseg kom raug, cais cov khoom siv roj teeb sib txawv, thiab teeb tsa lub hauv paus rau kev rov ua dua tshiab thiab kev ua tiav tom qab.
Tom qab ntawd, cov khoom siv roj teeb uas tau muab faib ua pawg no yuav nkag mus rau hauv "chaw ua haujlwm" sib txawv rau kev ua cov txheej txheem sib cais. Cov khoom siv electrode zoo uas muaj cov hlau xws li lithium, cobalt, thiab nickel yuav raug xa mus rau "chaw ua haujlwm rho tawm hlau". Los ntawm hydrometallurgy, pyrometallurgy thiab lwm yam txheej txheem, cov hlau muaj nqis no yuav raug rho tawm rau kev tsim cov roj teeb lithium tshiab lossis lwm yam khoom.
Cov khoom siv roj teeb uas muaj cov tshuaj lom xws li electrolytes thiab cov hlau hnyav yuav raug xa mus rau "chav ua haujlwm kho ib puag ncig" tshwj xeeb, qhov chaw uas lawv yuav dhau los ntawm ntau cov txheej txheem kho kom nruj kom ntseeg tau tias cov tshuaj lom raug pov tseg kom zoo thiab tsis muaj kuab paug rau ib puag ncig.
Nws tsim nyog hais tias nyob rau hauv cov txheej txheem rov ua dua tshiab ntawm cov roj teeb lithium pov tseg, kev tiv thaiv ib puag ncig yog qhov tseem ceeb tshaj plaws. Txhawm rau kom txo qis kev ua qias tuaj ib puag ncig, ntau lub tuam txhab tau siv cov thev naus laus zis thiab cov khoom siv tiv thaiv ib puag ncig siab heev, xws li cov khoom siv rov ua dua tshiab ntse ntawm cov roj teeb lithium pov tseg.
Cov khoom siv no zoo li "tus neeg tiv thaiv ib puag ncig" uas muaj riam phom tag nrho. Nws koom ua ke ntau yam kev tiv thaiv xws li cov txheej txheem kaw thiab cov txheej txheem ntxuav, uas tuaj yeem tiv thaiv cov pa phem thiab cov dej khib nyiab kom tsis txhob xau, kom ntseeg tau tias tag nrho cov txheej txheem rov ua dua tshiab yog ntsuab, zoo rau ib puag ncig thiab muaj kev nyab xeeb.
Cov txiaj ntsig kev lag luam ntawm kev siv cov roj teeb lithium rov ua dua tshiab
Qee lub tuam txhab kuj tseem tab tom tshawb nrhiav ntau cov txheej txheem rov ua dua tshiab uas txuag hluav taws xob thiab zoo rau ib puag ncig, xws li cov txheej txheem tshiab ntawm "kev sib xyaw ua ke ntawm qhov kub qis + electrolyte cryogenic recycling". Cov txheej txheem no zoo li "tus neeg saib xyuas tsev pheej yig", uas tuaj yeem txo tus nqi ntawm kev siv roj teeb lithium rov ua dua tshiab. Kev siv hluav taws xob thiab kev tso pa tawm carbon, thiab koom ua ke lub tswv yim ntawm kev txuag hluav taws xob thiab kev txo qis pa tawm rau hauv txhua qhov txuas.
Nrog kev nce qib tas mus li thiab kev siv thev naus laus zis, kev siv rov qab ua haujlwm zoo thiab qib kev tiv thaiv ib puag ncig ntawm cov roj teeb lithium siv tau zoo dua qub, ua rau muaj txiaj ntsig zoo rau kev siv cov peev txheej rov ua dua tshiab thiab kev tiv thaiv ib puag ncig.
Kev siv dua cov khoom sivroj teeb lithiumtsis yog tsuas yog ib qho project tiv thaiv ib puag ncig xwb, tab sis kuj muaj txiaj ntsig zoo rau kev lag luam. Cov lithium, cobalt, nickel thiab lwm yam hlau uas tau rho tawm los ntawm cov roj teeb lithium siv lawm zoo li cov khoom muaj nqis uas pw tsaug zog. Thaum sawv los, tuaj yeem rov qab tau nws cov ci ntsa iab thiab tsim cov txiaj ntsig zoo rau kev lag luam.
Tsis tas li ntawd xwb, kev tsim kho tshiab hauv thev naus laus zis kuj yog lub cav tseem ceeb los txhawb kev txhim kho kev lag luam rov ua dua roj teeb lithium pov tseg. Tsuas yog los ntawm kev rhuav tshem cov teeb meem kev siv tshuab thiab txhim kho kev siv rov ua dua tshiab thiab kev siv cov peev txheej peb thiaj li daws tau cov teeb meem ib puag ncig uas tshwm sim los ntawm cov roj teeb lithium pov tseg thiab ua tiav kev txhim kho kev lag luam.
Vim li no, ntau lub tuam txhab thiab cov tsev kawm tshawb fawb tau nce lawv cov peev txheej R&D thiab tshawb nrhiav cov thev naus laus zis thiab cov txheej txheem rov ua dua tshiab, thiab tau ua ntau yam kev tshawb pom tshiab. Qee lub tuam txhab tau tsim cov khoom siv rho tawm ntau dua uas tuaj yeem ua tiav kev rho tawm cov roj teeb lithium pov tseg kom zoo dua thiab muaj kev nyab xeeb; qee lub tsev kawm tshawb fawb tau cog lus los tsim cov thev naus laus zis rho tawm hlau uas zoo rau ib puag ncig thiab ua haujlwm tau zoo, siv zog los txhim kho cov nqi rov qab hlau thiab txo cov pa phem ib puag ncig.
Xaus lus
Kev siv cov roj teeb lithium uas siv lawm rov qab tsis yog tsuas yog lub luag haujlwm ntawm cov tuam txhab thiab tsoomfwv xwb, tab sis kuj xav tau kev koom tes ntawm tag nrho lub zej zog. Raws li cov neeg siv khoom ib txwm, peb tuaj yeem pib los ntawm peb tus kheej thiab koom nrog hauv kev siv cov roj teeb lithium uas siv lawm rov qab los pab txhawb kev tiv thaiv ib puag ncig.
Peb tuaj yeem xaiv xa cov xov tooj ntawm tes, laptops thiab lwm yam khoom siv hluav taws xob uas siv lawm mus rau cov chaw rov ua dua tshiab tsis tu ncua es tsis txhob pov tseg lawv thaum twg 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 pabcuam rov ua dua tshiab roj teeb; peb kuj yuav tsum txhawb nqa qhov tseem ceeb ntawm kev rov ua dua tshiab cov roj teeb lithium siv lawm thiab txhawb kom ntau tus neeg koom nrog hauv qhov kev tiv thaiv ib puag ncig no.
Kev siv dua cov khoom sivroj teeb lithiumyog ib txoj haujlwm ntev thiab nyuaj, tab sis peb muaj laj thawj ntseeg tias nrog kev sib koom tes ntawm tsoomfwv, cov tuam txhab lag luam thiab txhua lub koom haum hauv zej zog, peb yuav muaj peev xwm pib txoj kev txhim kho ntsuab thiab ruaj khov, yog li cov roj teeb lithium siv lawm yuav tsis yog lub nra hnyav rau ib puag ncig, tab sis dhau los ua cov peev txheej muaj txiaj ntsig thiab pab txhawb rau kev tsim lub ntiaj teb zoo nkauj.
Yog tias koj muaj lus nug lossis xav paub ntxiv, thov tsis txhob yig tiv tauj pebncav tes rau peb.
