Lithium-ion roj teeb rov ua dua qhov system

Peb tuaj yeem muab tag nrho cov kab rau lub lithium-ion roj teeb rov ua haujlwm kom tau txais cov hmoov anode thiab cathode, thiab cov hlau xws li hlau, tooj liab thiab txhuas.Peb tuaj yeem tshawb xyuas cov roj teeb lithium-ion hauv qab no thiab cov txheej txheem rov ua dua tshiab.

Cov roj teeb lithium-ion tuaj yeem muab faib ua ntau hom raws li lawv qhov sib xyaw thiab tsim.Ntawm no yog cov hom ntau tshaj plaws:

1. Lithium Cobalt Oxide (LiCoO2) - Qhov no yog hom roj teeb lithium-ion ntau tshaj plaws thiab siv dav hauv cov khoom siv hluav taws xob.
2. Lithium Manganese Oxide (LiMn2O4) - Hom roj teeb no muaj qhov tso tawm ntau dua li LiCoO2 roj teeb thiab feem ntau siv hauv cov cuab yeej hluav taws xob.
3. Lithium Nickel Manganese Cobalt Oxide (LiNiMnCoO2) - Kuj hu ua NMC roj teeb, hom no yog siv rau hauv tsheb hluav taws xob vim lawv lub zog ceev thiab cov nqi tso tawm siab.
4. Lithium Iron Phosphate (LiFePO4) - Cov roj teeb no muaj lub neej ntev dua thiab suav tias yog ib puag ncig zoo dua vim tias lawv tsis muaj cobalt.
5. Lithium Titanate (Li4Ti5O12) - Cov roj teeb no muaj lub neej voj voog siab thiab tuaj yeem them thiab tawm sai sai, ua rau lawv zoo tagnrho rau kev siv zog cia.
6. Lithium Polymer (LiPo) - Cov roj teeb no muaj cov qauv siv tau yooj yim thiab tuaj yeem ua rau cov duab sib txawv, ua rau lawv zoo tagnrho rau cov khoom siv me me xws li smartphones thiab ntsiav tshuaj.Txhua hom lithium-ion roj teeb muaj nws qhov zoo thiab qhov tsis muaj zog, thiab lawv cov ntawv thov sib txawv nyob ntawm lawv cov yam ntxwv.

Cov txheej txheem rov ua dua lithium-ion roj teeb yog txheej txheem ntau kauj ruam uas suav nrog cov kauj ruam hauv qab no:

1. Kev sau thiab txheeb xyuas: Thawj kauj ruam yog los sau thiab txheeb xyuas cov roj teeb uas siv los ntawm lawv cov chemistry, cov ntaub ntawv, thiab cov xwm txheej.
2. Tshem Tawm: Cov kauj ruam tom ntej yog tso cov roj teeb kom tsis txhob muaj lub zog seem ntawm qhov ua rau muaj kev phom sij thaum lub sijhawm rov ua dua.
3. Txo qhov loj me: Cov roj teeb ces muab txiav rau hauv me me kom cov khoom sib txawv tuaj yeem sib cais.
4. Kev sib cais: Cov khoom siv shredded yog ces muab cais rau hauv nws cov hlau thiab tshuaj lom neeg siv ntau txoj kev xws li sieving, sib nqus sib nqus, thiab flotation.
5. Purification: Cov khoom sib txawv tau ua kom huv ntxiv kom tshem tawm cov impurities thiab cov kab mob.
6. Refining: Cov theem kawg yuav ua kom cov hlau thiab cov tshuaj sib cais rau hauv cov ntaub ntawv tshiab uas tuaj yeem siv los tsim cov roj teeb tshiab, lossis lwm yam khoom.Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov txheej txheem rov ua dua tshiab yuav txawv nyob ntawm seb hom roj teeb thiab nws cov khoom tshwj xeeb, nrog rau cov kev cai hauv zos thiab cov peev txheej rov ua dua tshiab.
