Lithium-ion roj teeb (tom qab no hu ua lithium roj teeb) yog tam sim no nyob rau hauv lub hwj chim qhov chaw lag luam ntawm portable hluav taws xob thiab hluav taws xob khoom txij li thaum nws lag luam vim high voltage siab, muaj peev xwm loj, lub neej ntev thiab tsis nco qab, thiab sai sai nyob rau hauv lub hwj chim qhov chaw lag luam ntawm portable hluav taws xob khoom siv hluav taws xob txij li thaum nws ua lag luam. Loj. Lithium roj teeb yog ib qho khoom siv hluav taws xob, lub neej yog li 3A.

Cov roj teeb lithium tom qab cov khoom pov tseg, xws li kev kho tsis raug, hexafluorophosphate muaj nyob rau hauv hexafluorophosphate, carbonate organic teeb meem, thiab cobalt, tooj liab, thiab lwm yam, yuav ua rau muaj kev phom sij rau ib puag ncig. Ntawm qhov tod tes, cobalt, lithium, tooj liab thiab yas hauv cov roj teeb lithium pov tseg yog cov peev txheej muaj txiaj ntsig, nrog cov nqi rov qab siab heev.

Yog li ntawd, kev kho mob zoo rau cov roj ntsha lithium pov tseg, tsis tsuas yog muaj txiaj ntsig zoo ib puag ncig, tab sis kuj muaj txiaj ntsig zoo rau kev lag luam. Lub roj teeb lithium feem ntau yog tsim los ntawm vaj tse, zoo electrode, tsis zoo electrode, thiab electrolyte thiab membrane. Qhov zoo electrode yog ua los ntawm lithium cobalt hmoov rau ob sab ntawm aluminium foil concentration kua los ntawm kev sib koom ua ke PVDF; Cov qauv tsis zoo electrode zoo ib yam li qhov zoo electrode, thiab yog sib koom ua ke los ntawm cov hmoov carbon ntawm ob sab ntawm tooj liab ntawv nyiaj collector.

Tam sim no, cov pov tseg lithium roj teeb cov kev tshawb fawb feem ntau yog tsom rau kev rov qab los ntawm cov khoom muaj txiaj ntsig zoo ntawm cov hlau cobalt thiab lithium, thiab kev sib cais thiab rov qab cov ntaub ntawv tsis zoo electrode. Txhawm rau txhawm rau txhawm rau txhim kho kev lag luam sai, qhov muaj peev txheej loj zuj zus ntxiv thiab kev ua qias tuaj ib puag ncig, thiab tag nrho cov khoom siv rov ua dua tshiab thiab siv cov khoom pov tseg tau dhau los ua kev pom zoo thoob ntiaj teb. Tooj liab (cov ntsiab lus ntawm 35%) nyob rau hauv qhov tsis zoo electrode ntawm cov khib nyiab lithium roj teeb yog siv dav siv cov khoom tseem ceeb, uas yog adhered rau toner, uas yuav siv tau raws li additives xws li yas, roj hmab.

Yog li ntawd, nws muaj txiaj ntsig zoo rau kev sib cais ntawm lithium roj teeb tsis zoo cov khoom siv, thiab nws tau txhawb nqa kom muaj peev xwm ntawm kev tshem tawm, tshem tawm nws cov kev cuam tshuam ib puag ncig. Feem ntau siv cov khib nyiab lithium roj teeb muaj xws li ntub dej metallurgy, hluav taws ua metallurgy thiab mechanical physics. Piv nrog rau cov ntub dej thiab hluav taws kub, cov tshuab physics tsis tas yuav siv cov tshuaj reagents, thiab kev siv hluav taws xob qis dua yog ib txoj hauv kev zoo thiab muaj txiaj ntsig zoo.

Raws li cov yam ntxwv ntawm cov qauv tsis zoo electrode ntawm lithium roj teeb, tus sau siv lub vijtsam tawg thiab cov txheej txheem airflow sorting ua ke kom cais cov kev tshawb fawb ntxiv kom ua tiav kev sib cais ua haujlwm siab thiab rov qab los ntawm anematic tooj liab thiab toner. Cov khoom pov tseg lithium roj teeb zoo thiab qhov tsis zoo rov qab siv cov cuab yeej ua haujlwm: Raws li cov qauv zoo thiab tsis zoo electrode ntawm lithium roj teeb thiab nws cov khoom muaj pes tsawg leeg ntawm tooj liab thiab toner, nws yog tsim los ntawm ib feem rauj, kev vibration screening thiab airflow sorting ua ke txheej txheem kom pov tseg lithium roj teeb tsis zoo electrode Khoom siv rau kev sib cais thiab rov ua dua tshiab. Kev sim siv ICP-AES kev soj ntsuam kuaj cov qauv thiab cov xim hlau sib cais cov khoom muaj txiaj ntsig.

Cov txiaj ntsig tau pom tias tom qab cov khoom siv aperture tau tawg, cov tooj liab yog 92.4% hauv cov khoom tawg ntau dua 0.250 hli, thaum lub particle loj tsawg dua 0.

125 hli yog 96.6%, uas tuaj yeem rov qab ncaj qha. Hauv cov khoom tawg uas muaj qhov loj me ntawm 0.

125 mus rau 0.250 hli, qib ntawm tooj liab yog tsawg, thiab kev sib cais zoo ntawm cov tooj liab thiab cov toner tuaj yeem ua tiav los ntawm airflow sorting; Thaum lub sij hawm airflow sorting, kev khiav hauj lwm roj ntws tus nqi yog 1.00m / s, tooj liab Tus nqi rov qab yog 92.

3%, nrog rau saj ntawm 84.4%. Lo lus tseem ceeb: pov tseg lithium-ion roj teeb; cov khoom tsis zoo electrode; tawg; airflow tsi.

Qhov zoo thiab qhov tsis zoo electrode rov qab cov cuab yeej ntawm cov khib nyiab lithium roj teeb: 1) Los ntawm kev sib tsoo, kev tshuaj ntsuam kev vibration thiab airflow sorting txheej txheem tuaj yeem paub txog kev siv cov khoom siv hlau tooj liab thiab toner hauv cov khoom siv hluav taws xob tsis zoo ntawm cov roj teeb lithium. 2) Cov khoom siv hluav taws xob tsis zoo tuaj yeem paub txog kev sib nrig sib tev ntawm lub toner thiab cov ntawv ci tooj liab, thiab tom qab ntawd cov ntawv ci tooj liab thiab cov hmoov carbon hmoov tau pib sib cais los ntawm vibrating sieve ntawm qhov me me thiab qhov sib txawv ntawm cov duab. Lub rauj chammeters thiab sieve sib cais tshwm sim qhia tau hais tias cov tooj liab thiab carbon hmoov yog enriched nyob rau hauv ib tug particle loj dua 0.

250 hli thiab particle loj ntawm tsawg dua 0.125 hli, raws li, thiab cov qib siab li 92.4% thiab 96.

6%, thiab lawv tuaj yeem xa ncaj qha rau cov lag luam hauv qab. siv. 3) Rau crushing hais muaj ib tug particle loj ntawm 0.

125 mus rau 0.250 hli, tooj liab tsis tshua muaj, cov roj ntws sorting tuaj yeem siv los ua kom muaj kev sib cais zoo ntawm tooj liab thiab toner, thiab tau txais cov txiaj ntsig zoo rov qab thaum lub airflow ceev yog 1.00 m / s.

Tus nqi rov qab ntawm cov hlau tooj liab tuaj yeem ncav cuag 92.3%, thiab cov khoom yog 84.4%.

Cov khoom siv no tsuas yog siv rau cov tuam txhab roj teeb lithium-ion, sib cais cov aluminium Bo, tooj liab hoops hauv cov ntawv scrapped zoo thiab tsis zoo electrode, thiab cais cov khoom zoo thiab tsis zoo electrode rau kev siv tau. Cov cuab yeej ua tiav yog ua haujlwm nyob rau hauv lub xeev siab tsis zoo, tsis muaj plua plav raws plab, kev sib cais ua haujlwm tuaj yeem ncav cuag ntau dua 98%. .
