Cov yam ntxwv ua tus yam ntxwv ntawm Lithium Iron phosphate roj teeb

Kev loj hlob sai thiab cov seem loj
Txij li thaum tsim kho cov tsheb lag luam hluav taws xob, Tuam Tshoj tau ua lag luam loj tshaj plaws hauv ntiaj teb rau cov hlau Lithium phosphate. Tshwj xeeb, txij xyoo 2012 mus rau xyoo 2012, nws tau loj hlob ntawm tus nqi ntawm ze li 200%, thiab muag ntawm Lithium iron phosphate hauv 2013 tau hais txog ntau tshaj 50% ntawm kev muag khoom thoob ntiaj teb.
Hauv 2014, 75% ntawm cov roj ntsha lithium phosphate cathode cov roj teeb yog 7 ~ 800 tons hauv 7 xyoo phosphate yuav raug hloov los ntawm 2021.

Qhov kev phom sij yog qhov tseem ceeb
Cov tshuaj lom neeg muaj cov tshuaj lom muaj nyob hauv cov roj ntsha lithium phosphate roj teeb xws li LIPP6, organic carbonate, thiab tooj yog txhua qhov chaw pov tseg hauv tebchaws. Lipf6 yog cov xeb zoo thiab yooj yim rau kev txiav txim siab hauv dej los tsim HF. Organic cov kuab tshuaj thiab lawv cov khoom siv thiab cov khoom siv hydrourysis yuav ua rau muaj kuab paug loj rau cov huab cua, dej thiab ua kom raug mob rau cov ecosystem. Cov hlau hnyav xws li tooj liab accumulfulate nyob rau hauv ib puag ncig thiab thaum kawg ua rau tib neeg lawv tus kheej los ntawm kev siv roj ntsha saw; Thaum phosphorus nkag rau hauv cov pas dej thiab lwm lub cev dej, nws yooj yim heev rau kev ua kom muaj Eutstrophication ntawm cov dej lub cev. Nws tuaj yeem pom tau hais tias yog lub pov thawj lithium hluav taws xob phosphate roj teeb tsis rov ua kom muaj kev phom sij, nws yuav tsis muaj kev phom sij li, nws yuav tsis muaj kev phom sij li, nws yuav muaj kev noj qab haus huv thiab kev noj qab haus huv.

Kev siv thev naus laus zis yog tsis paub qab hau
Cov ntaub ntawv uas twb muaj lawm qhia tias kev rov ua dua lithium hluav taws xob roj teeb tau muab faib ua ob hom: ib qho yog kom rov ua haujlwm lithium phosphate cathore cov ntaub ntawv.
(1) Kev Rov Qab Los Ntawm Lithium Thiab Hlau
Hom txheej txheem no yog feem ntau yog raws lithium kev rov qab, vim lithium hlau phosphate tsis muaj cov hlau muaj txiaj ntsig, yog li txoj kev rov qab los ntawm cov roj ntsha cobalval oxide. Ua ntej, Lithium Iron phosphate roj teeb yog disassembled kom tau canhode cov khoom, thiab cov hmoov yog crushed thiab tshuaj ntsuam. Tom qab ntawd, cov kev daws teeb meem alkali tau ntxiv rau cov hmoov kom yaj aluminium thiab txhuas oxides, thiab lim lub lim slag muaj cov lithium thiab hlau. Leaching lub lim slag nrog cov tshuaj sib tov ntawm cov sulfuric acid thiab hydrogen peroxide (txo tus neeg sawv cev) kom tau txais qhov chaw ua haujlwm; Alkali tau ntxiv rau cov precaisitate hlau hydroxide thiab lim kom tau txais filtrate; Hlau oxide tuaj yeem tau los ntawm hlawv hlau hydroxide; Thaum kawg, tus nqi PHIB ntawm kev lim (5.0
(2) regenerated lithium iron phosphate
Ib qho kev rov ua kom rov zoo rau cov txiaj ntsig nyiaj txiag ntawm cov roj ntsha tsis ua haujlwm lithium iron phosphate uas tsis muaj cov khoom muaj peev xwm tsawg. Yog li ntawd, cov khoom {{-} theem theem yog siv los kho cov roj teeb lithium piv, uas muaj cov txiaj ntsig rov qab siv hluav taws xob thiab cov peev txheej muaj txiaj ntsig zoo.
Ua ntej, Lithium Iron phosphate roj teeb yog disassembled kom tau canhode cov khoom, thiab cov hmoov yog crushed thiab tshuaj ntsuam. Tom qab ntawd, kev kho cua sov tshem tawm cov ntawv seem thiab cov phau ntawv qhia, thiab tom qab ntawd cov kev daws teeb meem alkali tau ntxiv rau cov hmoov kom yaj aluminium thiab txhuas oxides; Lub taub lim dej slag muaj cov lithium thiab hlau tau lim, cov tshuaj pleev li cas, thiab cov hlau thiab phosphorus piv rau ntawm 1:1:1 Cov Lithium tshiab phosphate cathhore cov khoom siv tau los ntawm kev ntxiv cov pa roj carbon ntau thiab calcining rau hauv qhov chaw inert tom qab pob milling.

Lub cev rov ua dua tshiab tsis zoo tag nrho
Lub teb chaws "{{{863" Txoj Kev Npaj, tab sis siv roj teeb siab, tsuas yog siv roj teeb siab, tsuas yog siv hauv hluav taws xob hluav taws xob thiab ib qho me me. Yog li no, automotive roj teeb tseem tsis tau raug kaw hauv cov khoom loj, thiab cov txheej txheem kev siv hluav taws xob kev siv hluav taws xob uas tseem tsis tau tsim. Cov txheej txheem rov qab ua dua tshiab muaj qee cov teeb meem thiab kev ua tau zoo dua.
