Technology, Qhov zoo, thiab cov nqi ntawm Lithium-ion roj teeb

Lub roj teeb lithium-ion ua haujlwm li cas?Nws muaj txiaj ntsig dab tsi ntawm cov roj teeb lead-acid?Thaum twg lithium-ion roj teeb cia them tawm?A lithium-ion roj teeb(luv luv: lithiumion roj teeb lossis Li-ion roj teeb) yog lub ntsiab lus dav dav rau accumulators raws li cov khoom siv lithium hauv tag nrho peb theem, hauv qhov tsis zoo electrode, hauv qhov zoo electrode thiab hauv electrolyte, electrochemical cell.Lithium-ion roj teeb muaj lub zog tshwj xeeb piv rau lwm hom roj teeb, tab sis yuav tsum muaj hluav taws xob tiv thaiv hluav taws xob hauv feem ntau cov ntawv thov, vim tias lawv cuam tshuam tsis zoo rau ob qho tib si sib sib zog nqus tawm thiab overcharge.Cov roj teeb lithium ion hnub ci tau them nrog hluav taws xob los ntawm photovoltaic system thiab tawm rov qab raws li qhov xav tau.Rau lub sijhawm ntev, cov roj teeb txhuas tau suav tias yog lub hnub ci zoo tshaj plaws rau lub hom phiaj no.Txawm li cas los xij, raws li cov roj teeb lithium-ion muaj qhov ua tau zoo, txawm tias qhov kev yuav khoom tseem cuam tshuam nrog cov nqi ntxiv, uas yog, txawm li cas los xij, rov qab los ntawm kev siv lub hom phiaj.Technical Structure thiab Energy Storage Behavior of Lithium-ion BatteryCov roj teeb lithium-ion tsis txawv ntawm cov roj teeb lead-acid hauv lawv cov qauv.Tsuas yog tus nqi thauj khoom sib txawv: Thaum lub roj teeb raug them, lithium ions "migrate" los ntawm qhov zoo electrode mus rau qhov tsis zoo electrode ntawm lub roj teeb thiab nyob twj ywm "kho" nyob rau ntawd kom txog thaum lub roj teeb tawm dua.High-zoo graphite conductors feem ntau yog siv los ua electrodes.Txawm li cas los xij, kuj tseem muaj qhov sib txawv nrog cov hlau conductors lossis cobalt conductors.Raws li cov neeg siv khoom siv, cov roj teeb lithium-ion yuav muaj qhov sib txawv.Cov electrolyte nws tus kheej yuav tsum tsis muaj dej hauv lub lithium-ion roj teeb vim lithium thiab dej ua rau muaj kev kub ntxhov.Nyob rau hauv sib piv rau lawv cov lead-acid predecessors, niaj hnub lithium-ion roj teeb muaj (yuav luag) tsis muaj lub cim xeeb los yog nws tus kheej-tso tawm, thiab lithium-ion roj teeb khaws lawv lub zog tag nrho ntev.Lithium-ion fais fab cia roj teeb feem ntau muaj cov tshuaj manganese, npib tsib xee thiab cobalt.Cobalt (lub sij hawm tshuaj lom neeg: cobalt) yog ib yam khoom tsis tshua muaj thiab yog li ntawd ua rau cov khoom ntawm Li cia roj teeb kim dua.Tsis tas li ntawd, cobalt yog teeb meem rau ib puag ncig.Yog li ntawd, muaj ntau txoj kev tshawb fawb los tsim cov khoom siv cathode rau lithium-ion high-voltage roj teeb yam tsis muaj cobalt.Qhov zoo ntawm Lithium-ion roj teeb tshaj cov roj teeb-acidKev siv cov roj teeb lithium-ion niaj hnub coj nrog nws ntau qhov zoo uas cov roj teeb lead-acid yooj yim tsis tuaj yeem xa.Rau ib yam, lawv muaj lub neej ua haujlwm ntev dua li cov roj ntsha lead-acid.Lub roj teeb lithium-ion muaj peev xwm khaws cia lub hnub ci zog rau lub sijhawm ze li 20 xyoo.Tus naj npawb ntawm cov voj voog them thiab qhov tob ntawm qhov tso tawm kuj yog ntau zaus ntau dua nrog cov roj teeb txhuas.Vim yog cov khoom siv sib txawv siv hauv kev tsim khoom, cov roj teeb lithium-ion kuj tseem sib zog dua li cov roj teeb txhuas thiab ntau dua.Lawv, yog li ntawd, siv qhov chaw tsawg dua thaum lub sijhawm teeb tsa.Cov roj teeb lithium-ion kuj tseem muaj cov khoom khaws cia zoo dua ntawm kev tso tawm tus kheej.Tsis tas li ntawd, ib qho yuav tsum tsis txhob hnov ​​​​qab txog ib puag ncig: Vim tias cov roj teeb txhuas tsis yog ib puag ncig zoo hauv lawv cov khoom vim yog siv lead ua.Technical Key Figures ntawm Lithium-ion roj teebNtawm qhov tod tes, nws tseem yuav tsum tau hais tias, vim lub sijhawm ntev ntawm kev siv cov roj teeb txhuas, muaj ntau qhov kev tshawb fawb ntev ntev dua li cov roj teeb lithium-ion tseem tshiab, kom lawv siv thiab cuam tshuam cov nqi. tuaj yeem suav tau zoo dua thiab ntseeg tau ntau dua.Tsis tas li ntawd, kev nyab xeeb ntawm cov roj teeb txhuas niaj hnub no yog ib feem zoo dua li cov roj teeb lithium-ion.Hauv txoj ntsiab cai, kev txhawj xeeb txog qhov tsis xws luag hauv li ion hlwb kuj tsis yog qhov tsis muaj tseeb: Piv txwv li, dendrites, piv txwv li taw tes lithium deposits, tuaj yeem tsim rau ntawm anode.Qhov tshwm sim uas cov no ua rau luv luv Circuit Court, thiab yog li thaum kawg kuj ua rau thermal runaway (ib qho tshuaj tiv thaiv exothermic nrog muaj zog, nws tus kheej ua kom kub ceev), tshwj xeeb tshaj yog muab rau hauv lithium hlwb uas muaj cov khoom siv ntawm tes tsis zoo.Qhov phem tshaj plaws, kev nthuav tawm ntawm qhov ua txhaum no rau cov neeg nyob sib ze tuaj yeem ua rau muaj kev sib txuas lus thiab hluav taws kub hauv lub roj teeb.Txawm li cas los xij, raws li ntau thiab ntau tus neeg siv khoom siv roj teeb lithium-ion lithium-ion roj teeb, kev kawm los ntawm cov tuam txhab tsim khoom nrog ntau cov khoom loj kuj ua rau kev txhim kho ntxiv ntawm kev khaws cia thiab kev ua haujlwm siab dua ntawm cov roj teeb lithium-ion thiab tseem txo nqi ntxiv. .Cov txheej txheem kev txhim kho tam sim no ntawm Li-ion roj teeb tuaj yeem suav nrog hauv cov ntaub ntawv tseem ceeb hauv qab no:
