Kev lag luam roj teeb tau coj mus rau hauv lub zog lithium roj teeb "tso tawm"! kuv lub teb chaws yog tam sim no lub ntiaj teb loj tshaj plaws tshiab zog tsheb lag luam. Nrog rau qhov maj mam tas sij hawm ntawm lub roj teeb lub neej ntawm lub tsheb hluav taws xob, qhov ua pa ntawm lub zog lithium roj teeb kuj tau loj dua. .

Xyoo 2014, kuv lub teb chaws lub tsheb hluav taws xob muag tau 70,000; nyob rau hauv 2015, nws mus txog 300,000; nyob rau hauv 2016, nws mus txog 500,000; 2018, mus txog 10.53 lab. Nyob rau hauv 2018, CATL thiab BYD lub roj teeb nruab muaj peev xwm yog 23.

43 gWh thiab 11.43 gWh, feem; Nyob rau hauv thawj ib nrab ntawm 2019, CATL thiab BYD roj teeb nruab ntim yog 13.85 gWh thiab 7.

36g ua. Nws kwv yees tias los ntawm 2020, kuv lub teb chaws lub tsheb fais fab lithium roj teeb xav tau yuav ncav cuag 125GWH, thiab cov khib nyiab yuav ncav cuag 32GWH. Lub roj teeb seem yuav ncav cuag li 500,000 t; Txog rau xyoo 2030, lub zog lithium roj teeb yuav ncav cuag 101GWH, lub zog seem Lub roj teeb lithium yog li 1.

16 mln t. Tam sim no, muaj ob txoj hauv kev los rov ua dua cov khoom pov tseg dynamic lithium-ion roj teeb. Ua ntej, tus ntaiv yog siv, thiab qhov thib ob yog los rhuav tshem cov khoom siv rov ua dua tshiab.

Lub tuam txhab lithium-ion roj teeb rov ua dua tshiab yog qhov tseem ceeb rau kev rov ua dua cov khoom siv zoo ternary. Tsis tas li ntawd, qee lub tuam txhab me me feem ntau yog ua raws li cov ntaub ntawv zoo lithium hlau phosphate zoo, tab sis cov txheej txheem qis. Lub roj teeb uas tuaj yeem siv tau qis dua 50%, tsuas yog muab tshem tawm, thiab siv cov peev txheej rov qab los.

Tsis tas li ntawd, disassembly thiab kev siv cov khoom siv ntawm cov khoom siv khib nyiab kuj tseem xav tau rau cov roj teeb seem ntawm tus ntaiv. Hais txog cov khoom zoo electrode tso nyiaj rau lub roj teeb lithium-ion nrog tus nqi ntawm 40%, hauv kev rov qab los, tsom mus rau kev rov qab los thiab tom qab ntawd siv cov khoom zoo. Cov roj teeb lithium-ion tuaj yeem muab faib ua ob hom lithium hlau phosphate thiab cov ntaub ntawv ternary, thiab tseem ceeb rau cov tsheb npav thiab tsheb me me vim muaj kev nyab xeeb thiab lub voj voog.

Vim yog lub ntim loj ntawm cov khoom ntim, cov khoom siv roj teeb ternary yog qhov tseem ceeb rau lub coupe, kev lag luam hauv ob lub roj teeb yog nyob ib ncig ntawm 45%. Vim txoj kev loj hlob ntawm lithium hlau phosphate txoj kev loj hlob, tam sim no tus nqi ntawm silty phosphate ion roj teeb yog loj dua. Hais txog cov peev txheej rov qab los, cov tuam txhab kev lag luam tseem ceeb hauv tsev yog qhov tseem ceeb rau kev rov ua dua cov khoom zoo ntawm cov khoom siv peb sab.

Cov lithium hlau phosphate muaj 4% lithium, thiab lithium carbonate yog 1,70 kg, uas yog, 1T phosphate hmoov tuaj yeem rov qab tau 170 kg ntawm carbonate, thiab yog li ntawd, kev rov qab los ntawm lithium hlau phosphate daim hlau, tseem ceeb rov qab lithium thiab txhuas. Tam sim no, domestic recycling ntawm lithium hlau phosphate yog ib co tuam txhab me me. Vim yog vim li cas, qhov rov qab ntawm lithium hauv cov tuam txhab me yog li 85%, thiab lithium carbonate tuaj yeem rov qab los ntawm li 140 kg.

Tsis tas li ntawd, cov khoom tseem ceeb ntawm lithium hlau phosphate yog hlau phosphate, uas tau ua rau cov khoom pov tseg. Tam sim no, muaj qhov tseem ceeb ntawm cov khoom xyaw uas lysophosphate zoo electrode cov txheej txheem rov qab siv dua, thiab cov kua qaub-puag noj yog loj, tus nqi siab, thiab cov dej khib nyiab. Yog tias cov roj teeb lithium ion khib nyiab tsis raug kho, nws ncaj qha nkag mus rau hauv lub qhov cub smelting melting rau hauv ib qho hlau, thiab ntxiv yaj cov hlau, sib cais lub siab purity npib tsib xee thiab cobalt compound, thiab cov roj teeb meem hauv cov txheej txheem melting yuav tom qab purification.

Emissions, tseem ceeb siv nyob rau hauv pov tseg ntawm lithium-hydride thiab pov tseg cobalt acid lithium ion roj teeb. Cov txheej txheem hluav taws kub yog qhov yooj yim, yooj yim rau kev khiav lag luam, thiab muaj kev cuam tshuam ntau yam ntawm cov roj teeb pov tseg, tab sis cov txheej txheem ua haujlwm ntev, thiab kev rov qab zoo ntawm tus nqi qis. Tam sim no, cov txheej txheem tseem ceeb hauv tsev yog txoj hauv kev ntub dej, thiab nws yog ib qho tseem ceeb kom rov qab tau cov valbity hlau hauv cov khoom siv electrode zoo ntawm cov roj teeb lithium ion pov tseg.

Cov txheej txheem ntub dej yuav tsum tau pretreated rau lub roj teeb kom tau txais lub roj teeb pov tseg zoo electrode cov khoom siv hmoov, thiab cov hlau ion nyob rau hauv qhov zoo electrode ntawm inorganic acid yog tau, thiab cov hlau ion nkag mus rau hauv cov tshuaj, ces los nag, extraction, salting, ion pauv, electrochemical, thiab lwm yam. Kev sib cais ntxiv, cov khoom siv hlau xws li cobalt, npib tsib xee, thiab lithium yog purified. Hauv kev tsim khoom tiag tiag, cov txheej txheem leaching feem ntau siv hydrochloric acid, sulfuric acid thiab nitric acid los ntxuav cov khoom siv electrode, thiab ntxiv cov oxidizing tus neeg sawv cev, thiab hydrochloric acid yog leached.

Sodium hydrochloride yog siv los ua oxidant. Tam sim no, lub tuam txhab roj teeb rov ua dua cov pov tseg ntawm cov qub lithium tseem ceeb siv cov txheej txheem ntub dej, rov qab cov nqi ntawm cov khoom siv hluav taws xob zoo ternary. kuv lub teb chaws cov khoom pov tseg dynamic lithium-ion roj teeb rov ua dua yog nyob rau hauv thawj theem, thiab kev lag luam tseem ceeb feem ntau yog siv hauv cov ntaub ntawv ntub dej zoo electrode.

Lub pob txha pob txha lithium-ion roj teeb rov ua lag luam yog tsuas yog raws li kev rov ua dua ntawm peb yuan cov khoom zoo, thiab qee lub tuam txhab me tau ua cov khoom siv lithium hlau phosphate zoo kom rov qab tau cov khoom lag luam, tab sis tsuas yog cov lithium hauv cov khoom siv electrode zoo tsawg, qib kev ua haujlwm tsawg, thiab cov nqi tsim khoom siab dua. Yog li ntawd, txhawm rau kom ntseeg tau tias tag nrho cov khoom pov tseg ntawm lithium ion roj teeb, nws yog ib qho tsim nyog yuav tsum tau ua kev tshawb fawb ntawm cov electrode tsis zoo, electrolyte, diaphragm, thiab lwm yam, thiab ua tiav kev lag luam.

Tshwj xeeb tshaj yog nyob rau hauv dismantling, nws yog ib qhov tsim nyog los tsom rau lub cev sib cais ntawm cov nqi ntawm lithium-ion roj teeb uas muaj nuj nqis, txo cov nqi rov qab, ua kom muaj kev loj hlob ntawm kev lag luam lithium-ion roj teeb.
