Lub zog tshiab lub tsheb lag luam tau pib nce hauv 2014, thiab lub zog tshiab lub tsheb tau tshwm sim thaum lub sijhawm Olympic Games 2008. Raws li cov txheej txheem seem, lub zog lithium roj teeb seem ntawm tes lag luam tau pib. Nws yog kwv yees hais tias los ntawm 2018 kuv lub teb chaws kev txhawb siab lithium hlau phosphate yog Ameslikas Kev lag luam pov tseg rov ua lag luam yuav pib pib qhov ntsuas, nce 12.

08GWH ntawm kev siv cov roj teeb lithium pov tseg, thiab cov khoom seem yuav ncav cuag ib ncig ntawm 1.72,500 tons. Raws li kev ntsuas, tus naj npawb ntawm kev lag luam rov qab tsim los ntawm kev rov qab los ntawm cobalt, npib tsib xee, manganese, lithium, hlau thiab txhuas thiab txhuas hauv cov khib nyiab dynamic lithium-ion roj teeb yuav ncav cuag 5.

323 billion yuan, mus txog 10.1 billion yuan hauv 2020, 2023 pov tseg Lub zog lithium-ion roj teeb lag luam yuav ncav cuag 25 billion yuan. Lithium-ion roj teeb rov qab yog lub luag haujlwm hauv zej zog, lithium-ion roj teeb ib puag ncig, kev pov tseg tsis zoo, nyob rau hauv txoj kab nrog kev txhim kho kom ruaj khov.

Yog li ntawd, tsoomfwv tau siv cov neeg tsim khoom lub luag haujlwm txuas ntxiv, xav kom cov neeg tsim khoom muaj lub luag haujlwm rau cov roj teeb rov qab, lav lub roj teeb qhov chaw tswj tau, kom meej meej, txhawm rau txo qis kev ua haujlwm ntawm cov khoom siv rov ua dua tshiab; thaum tawm tswv yim rau hauv daim ntawv ntawm Pob Roj Teeb Pab Pawg, Txo cov teeb meem rov ua dua tshiab thiab txhim kho kev lag luam efficiency. Yuav ua li cas rov qab lithium hlau mov ntawm hlau phosphate? Lithium-ion roj teeb rov qab 1, tus ntaiv siv nrog cov khoom siv raw khoom rov qab so lub zog lithium ion roj teeb, nqa txoj kev siv txoj kev, yog tus ntaiv tom qab siv, cov khoom siv rov qab; cov ntaub ntawv ncaj qha rov qab yog tsawg dhau, tsis muaj keeb kwm, kev saib xyuas kev nyab xeeb tsis tsim nyog, thiab lwm yam. Ua raws cov txiaj ntsig kev lag luam yog lub zog tsav ntawm cov tuam txhab thiab kev coj noj coj ua.

Raws li qhov tseeb, tus ntaiv yog siv, thiab tus nqi muaj nyob rau hauv lub roj teeb yog txo rau tus nqi txij nkawm, thiab tom qab ntawd cov khoom siv raw cov ntaub ntawv rov qab yog lub roj teeb siab tshaj plaws. Txawm li cas los xij, qhov teeb meem tiag tiag yog tias cov roj teeb lithium thaum ntxov yog traceable, zoo, qauv tsis sib xws. Thaum ntxov roj teeb tus ntaiv yog siab, thiab tus nqi ntawm kev tshem tawm qhov kev pheej hmoo yog siab.

Yog li ntawd, nws tuaj yeem hais tau tias nyob rau theem pib ntawm lub zog lithium roj teeb rov qab, lub roj teeb lub hom phiaj yog ua raws li cov khoom siv raw rov qab. 2, cov khoom zoo electrode nqi hlau rho tawm txoj kev Lub zog tam sim no lithium ion roj teeb rov qab, qhov tseeb, tsis muaj kev rov qab zoo ntawm ntau yam khoom ntawm lub roj teeb. Cov ntaub ntawv zoo electrode muaj xws li: lithium cobaltate, lithium manganate, peb-dimensional lithium, lithium hlau phosphate ion roj teeb, thiab lwm yam.

Cov khoom siv roj teeb zoo raug nqi nyob hauv lub roj teeb monomer nqi 1/3 lossis ntau dua, thiab vim tias qhov tsis zoo electrode tam sim no siv ntau cov ntaub ntawv carbon xws li graphite, muaj tsawg daim ntawv thov ntawm lithium titanate Li4TI5O12 thiab silicon carbon tsis zoo electrode Si / C, yog li tam sim no lub roj teeb rov qab siv dua yog qhov tseem ceeb rau kev siv roj teeb zoo. Recycling method of waste lithium ion batteries Cov kev cai lij choj lub cev tseem ceeb, chemical method thiab biological law peb pawg. Piv nrog rau lwm txoj hauv kev, ntub dej metallurgy yog suav tias yog ib txoj hauv kev zoo tshaj plaws rov qab los vim nws qhov zoo ntawm kev siv hluav taws xob tsawg, kev ua haujlwm siab rov qab thiab cov khoom siab purity.

Lithium-ion roj teeb 1 Lub cev txoj kev physics txoj kev yog kho nrog lithium hlau phosphate ion roj teeb uas siv los ntawm cov txheej txheem tshuaj tiv thaiv lub cev. Cov txheej txheem kev kho lub cev feem ntau yog qhov tseem ceeb rau kev sib tsoo flotation txoj kev thiab kev sib tsoo tshuab. 2 Cov txheej txheem tshuaj yog ib txoj hauv kev kho cov roj teeb lithium-ion siv cov txheej txheem tshuaj lom neeg, thiab feem ntau muab faib ua ob txoj hauv kev ntawm hluav taws kub-raws li metallurgy thiab ntub dej metallurgy.

3 Txoj Cai Lij Choj Biological Metallurgical tam sim no tab tom ua tiav, uas siv cov txheej txheem metabolic ntawm cov kab mob microbial kom ua tiav cov kev xaiv leaching ntawm cov hlau xws li cobalt thiab lithium. Kev siv hluav taws xob lom neeg, tus nqi qis, thiab cov kab mob tuaj yeem rov qab siv tau, cov pa phem me me; Txawm li cas los xij, cov kev cai rau kev cog cov kab mob microbial yuav tsum tau ua, lub sijhawm kab lis kev cai ntev, kev ua haujlwm tsis zoo, thiab cov txheej txheem yuav tsum tau ua kom zoo dua ntxiv. Lub roj teeb muaj zog lithium-ion tam sim no yog qhov tseem ceeb rau kev rov ua dua cov kev cob qhia me me, cov tuam txhab kev lag luam rov ua dua tshiab thiab tsoomfwv cov chaw rov ua dua tshiab, thiab tsis tau tshwm sim hauv cov txheej txheem rov ua dua tshiab ntawm cov tuam txhab tsim hluav taws xob lithium roj teeb lossis hluav taws xob tsheb.
