1. Cov teeb meem muaj kuab paug tom qab rov ua dua lithium hlau phosphate
Lub zog roj teeb rov ua lag luam yog qhov loj, thiab raws li cov chaw tshawb fawb cuam tshuam, Tuam Tshoj cov roj teeb hluav taws xob so haujlwm tag nrho yuav tsum ncav cuag 137.4MWh los ntawm 2025.
noj lithium hlau phosphate roj teebRaws li ib qho piv txwv, muaj ob txoj hauv kev rau kev rov ua dua tshiab thiab siv cov roj teeb uas muaj feem xyuam nrog cov nyiaj laus: ib qho yog siv cascade, thiab lwm qhov yog dismantling thiab recycling.
Kev siv Cascade yog hais txog kev siv lithium hlau phosphate roj teeb uas muaj peev xwm ntxiv ntawm 30% mus rau 80% tom qab disassembly thiab recombination, thiab siv lawv mus rau qhov chaw qis zog xws li lub zog cia.
Dismantling thiab recycling, raws li lub npe qhia, hais txog kev rhuav tshem ntawm lithium hlau phosphate fais fab roj teeb thaum lub peev xwm seem tsawg dua 30%, thiab rov qab los ntawm lawv cov khoom siv raw, xws li lithium, phosphorus, thiab hlau hauv qhov zoo electrode.
Lub dismantling thiab recycling ntawm lithium-ion roj teeb tuaj yeem txo cov mining ntawm cov ntaub ntawv tshiab los tiv thaiv ib puag ncig thiab tseem muaj txiaj ntsig zoo rau kev lag luam, txo cov nqi mining, kev tsim khoom, nqi zog, thiab cov nqi tsim khoom.
Lub hom phiaj ntawm lithium-ion roj teeb dismantling thiab recycling feem ntau muaj cov kauj ruam hauv qab no: ua ntej, sau thiab faib cov roj teeb lithium pov tseg, tom qab ntawd tshem cov roj teeb, thiab thaum kawg cais thiab ua kom zoo dua cov hlau.Tom qab kev ua haujlwm, cov hlau thiab cov khoom siv tau zoo tuaj yeem siv rau kev tsim cov roj teeb tshiab lossis lwm yam khoom, txuag nqi ntau heev.
Txawm li cas los xij, tam sim no suav nrog ib pab pawg ntawm cov tuam txhab siv roj teeb, xws li Ningde Times Holding Co., Ltd. cov tuam txhab koom nrog Guangdong Bangpu Circular Technology Co., Ltd., txhua tus ntsib teeb meem pos: roj teeb rov ua dua tshiab yuav tsim cov khoom muaj kuab lom thiab tawm cov pa phem. .Kev ua lag luam xav tau cov thev naus laus zis tshiab los txhim kho cov pa phem thiab toxicity ntawm cov roj teeb rov ua dua tshiab.
2.LBNL pom cov ntaub ntawv tshiab los daws cov teeb meem muaj kuab paug tom qab siv roj teeb.
Tsis ntev los no, Lawrence Berkeley National Laboratory (LBNL) hauv Tebchaws Meskas tau tshaj tawm tias lawv tau pom cov khoom tshiab uas tuaj yeem siv cov roj teeb lithium-ion pov tseg nrog dej xwb.
Lawrence Berkeley National Laboratory tau tsim nyob rau xyoo 1931 thiab yog tswj hwm los ntawm University of California rau US Department of Energy's Science Office.Nws tau yeej 16 Nobel nqi zog.
Cov khoom tshiab tsim los ntawm Lawrence Berkeley National Laboratory hu ua Quick-Release Binder.Cov roj teeb lithium-ion ua los ntawm cov khoom siv no tuaj yeem siv tau yooj yim, ib puag ncig tus phooj ywg, thiab tsis muaj tshuaj lom.Lawv tsuas yog yuav tsum tau disassembled thiab muab tso rau hauv dej alkaline, thiab maj mam shaken kom cais cov ntsiab lus xav tau.Tom qab ntawd, cov hlau yog lim tawm ntawm cov dej thiab qhuav.
Piv nrog rau tam sim no lithium-ion recycling, uas koom nrog shredding thiab sib tsoo roj teeb, ua raws li los ntawm combustion rau hlau thiab cov khoom sib cais, nws muaj toxicity loj thiab tsis zoo ib puag ncig kev ua tau zoo.Cov khoom tshiab zoo li hmo ntuj thiab nruab hnub hauv kev sib piv.
Thaum lub Cuaj Hlis 2022, cov thev naus laus zis no tau raug xaiv los ua ib qho ntawm 100 kev hloov pauv thev naus laus zis tsim thoob ntiaj teb xyoo 2022 los ntawm R & D 100 Khoom plig.
Raws li peb paub, lithium-ion roj teeb muaj qhov zoo thiab tsis zoo electrodes, ib qho cais, electrolyte, thiab cov khoom siv, tab sis yuav ua li cas cov khoom sib xyaw ua ke hauv lithium-ion roj teeb tsis paub zoo.
Hauv cov roj teeb lithium-ion, cov khoom siv tseem ceeb uas tswj cov qauv roj teeb yog cov nplaum.
Tus tshiab Quick-Release Binder nrhiav tau los ntawm Lawrence Berkeley National Laboratory cov kws tshawb fawb yog ua los ntawm polyacrylic acid (PAA) thiab polyethylene imine (PEI), uas yog kev cob cog rua ntawm cov nyiaj them rau nitrogen atoms zoo nyob rau hauv PEI thiab tsis zoo nqi oxygen atoms nyob rau hauv PAA.
Thaum Quick-Release Binder muab tso rau hauv dej alkaline uas muaj sodium hydroxide (Na + OH-), cov sodium ions dheev nkag mus rau hauv qhov chaw nplaum, sib cais ob lub polymers.Cov polymers sib cais yaj mus rau hauv cov kua, tso tawm cov khoom siv electrode.
Hais txog tus nqi, thaum siv los tsim cov roj teeb lithium zoo thiab tsis zoo electrodes, tus nqi ntawm cov nplaum no yog kwv yees li ib feem kaum ntawm ob feem ntau siv.
