Txoj kev tuav pov tseg Lithium Ion roj teeb

Muaj ntau cov khoom siv tsis yog rov ua dua tshiab nrog cov txiaj ntsig kev lag luam siab, xws li cobalt, lithium, npib tsib xee, tooj liab, txhuas, thiab lwm yam Nws tuaj yeem tsis tsuas yog txo cov pa phem los ntawm cov roj teeb pov tseg, tab sis kuj tsis txhob nkim cov khoom siv hlau ntawm cobalt, npib tsib xee. , thiab lwm yam los ntawm kev rov ua dua cov khoom pov tseg lossis tsis tsim nyog lithium ion roj teeb.

Ktkbofan Energy New Material Co. Ltd nyob rau hauv Changzhou tau koom tes nrog tsev kawm ntawv qib siab thiab nrhiav tau ib pab pawg tshawb fawb raws li kev txhawb nqa los ntawm Jiangsu cov kws qhia ntawv University of thev naus laus zis, Jiangsu tsis tshua muaj hlau txheej txheem thev naus laus zis thiab daim ntawv thov tseem ceeb hauv chav kuaj. Nws lub ntsiab lus tshawb fawb yog rov ua dua cov hlau muaj txiaj ntsig los ntawm cov roj teeb lithium ion pov tseg. Tom qab peb xyoos kev tshawb fawb thiab kev tsim kho, nws tau daws cov teeb meem ntawm kev tsim khoom nyuaj, cov txheej txheem ntev, ib puag ncig kev phom sij los ntawm cov kuab tshuaj organic, txo cov txheej txheem thev naus laus zis, txo kev siv hluav taws xob, txhim kho cov hlau rov ua dua tshiab, purity thiab rov qab los, uas ua rau kev ua tiav ntawm txhua xyoo. 8000 tuj pov tseg lithium ion roj teeb tag nrho-pob rov siv dua thiab siv.

Qhov project no yog los ntawm kev siv cov khoom siv pov tseg. Lub hauv paus ntsiab lus yog cais thiab rov ua dua cov hlau tsis muaj hlau los ntawm hydrometallurgical extraction, suav nrog cov kua qaub, kua purification thiab concentration, hnyav extraction, thiab lwm yam. Nws kuj tsim cov khoom siv hlau los ntawm cov txheej txheem electrometallurgy (electrodeposition).

Cov txheej txheem cov txheej txheem yog: pretreatment ntawm pov tseg lithium ion roj teeb thaum xub thawj, nrog rau kev tso tawm, disassembling, smashing thiab sorting. Tom qab ntawd rov ua dua cov yas tom qab disassemble thiab hlau txheej. Extract cov ntaub ntawv electrode tom qab alkaline leaching, acid leaching thiab refining.

Extracting yog cov kauj ruam tseem ceeb cais tooj liab los ntawm cobalt thiab nickel. Tom qab ntawd cov tooj liab tau muab tso rau hauv qhov hluav taws xob electrodeposition thiab tsim cov electro deposited tooj liab ntau lawm. Extract dua tom qab rho tawm ntawm cobalt thiab npib tsib xee. Peb tuaj yeem tau txais cobalt ntsev thiab nickel ntsev tom qab crystallized concentration. Los yog coj cov cobalt thiab npib tsib xee tom qab rho tawm mus rau hauv electrodeposition slot, ces ua electro deposited cobalt thiab nickel khoom.

Kev rov qab los ntawm cobalt, tooj liab thiab npib tsib xee ntawm cov txheej txheem electro-deposition yog 99.98%, 99.95% thiab 99.2% ~ 99.9%. Ob qho tib si cobaltous sulfate thiab npib tsib xee sulfate cov khoom tau mus txog cov qauv tsim nyog.

Muaj scale-expansion & industrialization kev tshawb fawb thiab txhim kho nyob rau hauv optimized kev tshawb fawb ua tau zoo, teeb ib tug tag nrho enclosed huv huv ntau lawm kab ntawm pov tseg lithium ion roj teeb nrog ib xyoos rov qab ntawm tshaj 8000 tons, recycle 1500 tons cobalt, 1200 tons tooj liab, 420 tons nickel, uas yog tag nrho raug nqi ntau tshaj 400 lab yuan.

Nws tau hais tias tsis muaj hydrometallurgy hauv tsev. Nws kuj tsis tshua pom nyob rau txawv teb chaws. Tej zaum peb tuaj yeem sim coj txoj kev no mus rau hauv daim ntawv thov dav.

Qhov kev ua tiav no ua lub luag haujlwm tseem ceeb ntawm lub teb chaws pov tseg Li ion roj teeb recycling, thiab ua tau zoo ntxiv lub zog cia. Piv nrog rau lwm lub lag luam roj teeb, nws muaj qhov zoo tshaj plaws nrog rau ib puag ncig tus phooj ywg, tus nqi qis thiab cov txiaj ntsig siab.

Nws tuaj yeem koom ua ke thiab tsuas yog cov txheej txheem thev naus laus zis los ntawm hydrometallurgy, uas muaj kev siv hluav taws xob tsawg tab sis cov khoom lag luam siab.
