Cov tuam txhab roj teeb lithium-ion tham txog qhov xwm txheej tam sim no ntawm kev lag luam pov tseg lithium roj teeb thiab lithium-ion roj teeb rov qab thev naus laus zis. Nrog rau kev nce ntxiv ntawm lub zog tshiab tsheb, tsuas yog qhov loj-scale muaj zog lithium-ion roj teeb xav tau, thiab kev lag luam muaj peev xwm rau lithium-ion roj teeb rov qab thiab siv ntaiv, txhim kho lithium-ion roj teeb rov ua dua thiab siv ntaiv hauv kev tiv thaiv cov khoom pov tseg ntawm cov pa phem kuj tseem yuav muaj txiaj ntsig kev lag luam thiab kev nqis peev ntau. Cov tuam txhab roj teeb lithium-ion hauv qab no tham txog qhov xwm txheej tam sim no ntawm kev lag luam pov tseg lithium roj teeb thiab cov cuab yeej siv rov qab ntawm lithium-ion roj teeb.

Cov xwm txheej tam sim no ntawm lithium cov ntsiab lus hauv kev lag luam pov tseg lithium-eM raws li cov khoom siv dav siv hauv cov roj teeb lithium-ion, uas tau siv dav, thiab tam sim no tus nqi ntawm lithium carbonate ntawm lub khw yog pheej yig heev, kev thov, tshwj xeeb tshaj yog lub zog tsav tsheb tshiab, kev xav tau nthuav dav, thiab cov khoom siv-rau-muab cov khoom lag luam, qhov nyuaj ntawm kev tso tawm yog qhov zoo rau cov nqi ntawm lithium carbonate ntawm cov khw muag khoom, uas tau txais txiaj ntsig zoo dua rau cov tuam txhab lithium thiab carbonate. roj teeb. Xyoo 2018, nws tau suav tias yog thawj xyoo ntawm cov roj teeb lithium dynamic, tsav tsheb nrawm nrawm ntawm cov ntsuas hluav taws xob lithium-ion roj teeb, thiab kev siv cov roj teeb pov tseg lithium-ion tau dhau los ua qhov tseem ceeb ntawm cov roj teeb rov qab. Lub roj teeb lithium ion ntawm lub tsheb fais fab muaj ntau ntawm lithium, manganese, npib tsib xee, thiab cobalt, thiab lwm yam.

, kuj muaj cov nqi qis dua xws li hlau thiab tooj liab. Recycling no priceless hlau los ntawm lub hwj chim lithium roj teeb muaj kev khwv nyiaj txiag siab, thaum tseem txo cov pa phem rau ib puag ncig. Kev lag luam loj ntawm 2020 pov tseg lithium roj teeb rov ua dua thiab ntaiv yuav tsum ncav cuag 10 billion yuan.

Lub zog tam sim no muaj zog lithium roj teeb rov qab lub cev tseem ceeb muaj qhov tseem ceeb ntawm kev rov ua haujlwm me me, lub tuam txhab kev lag luam rov ua dua tshiab thiab tsoomfwv cov chaw rov ua dua tshiab, thiab tsis tau tshwm sim hauv kev rov ua dua tshiab ntawm lub tuam txhab hluav taws xob lithium roj teeb lossis lub tuam txhab hluav taws xob tsheb. Tam sim no, cov khoom siv rov ua dua tshiab ntawm cov roj teeb lithium-ion dynamic yog qhov tseem ceeb rau kev rov ua haujlwm me me, thiab cov tuam txhab kev lag luam rov ua dua tshiab thiab tsoomfwv cov chaw rov ua dua tshiab tsawg dua, cov txheej txheem yuav tsum tau rov ua dua tshiab. Feem ntau ntawm cov khib nyiab dynamic lithium roj teeb tau ntws mus rau hauv qhov tsis muaj qhov tsim nyog refurbishment Rhiav, cov tuam txhab txheej txheem cov cuab yeej yog qab.

Txawm li cas los xij, yog tias nws raug xa mus rau npe rau cov se them raws li txoj cai, cov kev tsim nyog tau txais thiab emissions raws li lub teb chaws tus qauv yuav ua rau tsis muaj kev sib tw. Yog li ntawd, nws yog ib qho tsim nyog los txhim kho kev txhim kho kom ruaj khov ntawm txoj cai kom ntseeg tau tias kev lag luam roj teeb rov qab los. Lithium-ion roj teeb rov qab technology 1.

Kev kub kub metallurgical txoj kev: Kub-kub calcination tsuas yog mechanically crushed los ntawm ib tug pov tseg lithium-ion roj teeb, thiab cov hmoov zoo uas muaj hlau thiab hlau oxides sieved. Kub kub metallurgy txheej txheem cov yam ntxwv: txheej txheem yog kuj yooj yim, haum rau loj-scale ua; roj teeb electrolytes thiab lwm yam khoom xyaw tuaj yeem ua rau huab cua paug. Thib ob, ntub dej metallurgy: Tom qab tawg lub roj teeb, xaiv yaj nrog cov tshuaj reagent tsim nyog, cais cov ntsiab lus hlau hauv cov kua leaching.

Cov txheej txheem ntub dej ntub dej nta: cov txheej txheem zoo ruaj khov yog tsim nyog rau kev rov qab los ntawm cov roj teeb lithium-ion me me thiab nruab nrab; tus nqi siab, cov kua khib nyiab yuav tsum tau ua ntxiv. Thib peb, physics dismantling: faib cov roj teeb pob, kuaj xyuas, sib nqus sib nqus sib cais, nplua pulverization thiab kev faib tawm kom tau txais cov ntsiab lus siab, thiab tom qab ntawd ua cov txheej txheem ntawm kev rov qab los tom ntej. Lub cev dismantling txheej txheem cov yam ntxwv: kev ua haujlwm qis, siv sijhawm tsawg; txheej txheem yog ib puag ncig zoo heev, yuav tsis ua rau cov pa phem thib ob rau ib puag ncig.

Feem ntau, cov khib nyiab lithium-ion roj teeb ib puag ncig yog siab, tab sis tus nqi rov qab yog siab, thiab cov khoom hlau tsis tshua muaj, cov khoom lag luam tuaj yeem cia siab rau cov khoom siv hlau ntau dua. Nyob rau tib lub sijhawm, rau lub tuam txhab, kev rov ua dua ntawm cov pov tseg lithium hluav taws xob kuj muaj cov hauv kev lag luam. Tom qab kev rov ua haujlwm zoo, nws tuaj yeem muaj ntau tus nqi tsim khoom rau cov roj teeb ntau lawm, nrog rau kev lag luam loj heev.
