Cov roj teeb lithium-ion muaj ntau yam tshuaj lom neeg, siab corrosive thiab muaj kuab paug. Tsis tas li ntawd, cov roj teeb lithium-ion electrolyte muaj cov tshuaj lom heev, flammable thiab tawg, corrosive electrolyte thiab organic hnyav, ces yuav ua li cas nrog cov roj teeb lithium ion khib nyiab? Lub neej ntawm lithium-ion roj teeb feem ntau yog peb xyoos, tam sim no siv ntau thiab ntau hom roj teeb lithium-ion. Thaum rov qab los, nws kuj txawv ntawm tus nqi ntawm hom lithium ion roj teeb.

Qhov tseeb, lub roj teeb lithium-ion muaj ntau cov hlau tooj liab thiab lithium hmoov, uas yog cov peev txheej tsawg heev. Cov roj teeb lithium ion pov tseg ntawm kev ua lag luam yuav muaj ntau txhiab tons ntawm kev tsim khoom ib xyoos. Yog tias cov kev rov qab los no yuav muaj kev lag luam siab heev.

Cov roj teeb lithium-ion khib nyiab muaj nyob rau hauv cov khoom hlau xws li cobalt, lithium, npib tsib xee, tooj liab, txhuas thiab hlau. Qhov loj feem ntawm cobalt ions tuaj yeem siab li 15%, uas yog 850 npaug ntawm cov ntsiab lus cobalt ore, deb tshaj qhov tsim ntawm cobalt mines hauv kuv lub tebchaws. tawm.

Nyob rau tib lub sijhawm, cov ntawv ci tooj liab ntawm aluminium ntawv ci thiab cov kua dej tsis zoo electrode raws li cov kua dej electrode zoo hauv cov qauv ntawm lithium ion roj teeb kuj tseem muaj txiaj ntsig zoo. Kev nqis peev hauv Kaidi mob qog noj ntshav ion roj teeb crusher cov khoom siv, rov ua kom zoo dua hauv cov roj teeb lithium-ion, txo cov pa phem los ntawm ib puag ncig muaj kuab paug, txo cov peev txheej tsis muaj, thiab lwm yam, muaj qhov tseem ceeb ntawm kev sib raug zoo thiab kev lag luam.

Kev kho cov khib nyiab lithium ion roj teeb Kev kho cov txheej txheem ntub dej los kho cov roj lithium-ion pov tseg tam sim no tau kawm ntau thiab ntau cov txheej txheem paub tab, kev paub tseem ceeb 3 theem: 1) Kev tshem tawm tag nrho ntawm cov khoom siv pov tseg lithium ion roj teeb, kev sib cais yooj yim Tos pretreatment, tom qab kev tshuaj ntsuam tau txais, ib qho tseem ceeb electrode cov khoom tau txais, thiab cov khoom siv organic tau txais, 2) Cov khoom siv hluav taws xob tau txais los ntawm kev ua kom cov khoom siv hluav taws xob tau txais tom qab kev kho mob ua ntej, kom cov hlau sib txawv thiab lawv cov khoom sib txuas rau hauv cov leach hauv daim ntawv ntawm ions. Tuam Tshoj; 3) Kev sib cais thiab rov qab ntawm cov hlau hauv cov kua leaching yog qhov tseem ceeb thiab nyuaj rau kev kawm txog cov txheej txheem kho cov roj teeb lithium-ion pov tseg.

Tam sim no, txoj kev sib cais thiab rov qab yog qhov tseem ceeb nrog cov kuab tshuaj extraction, nag lossis daus, electrolysis, ion exchange method, salting thiab etiology. .
