Lub zog cia siv lithium hlau phosphate roj teeb pob muaj kev nyab xeeb los yog tsis? Thaum nws los txog rau cov roj teeb lithium hlau phosphate, peb yuav ua ntej yuav txhawj xeeb txog nws txoj kev nyab xeeb, ua raws li nws cov kev siv. Hauv kev siv lub zog cia, lub zog cia yuav tsum muaj kev ruaj ntseg zoo, lub neej voj voog siab, txo tus nqi ntawm cov roj teeb lithium. Yog li, lithium hlau phosphate roj teeb muaj kev nyab xeeb los yog tsis? Nyob rau hauv daim ntawv no, XUANLI quab yuam hluav taws xob editor coj koj mus nrhiav.
Hauv Suav teb, cov cai tseem tau tshaj tawm tsis ntev los no los txhawb thiab tswj kev txhim kho ntawm lub zog cia thiab muab cov kev cai rau cov qauv kev nyab xeeb cuam tshuam. Rau electrochemical zog cia fais fab nroj tsuag hluav taws xob tiv thaiv, cov ncauj lus kom ntxaws yuav tsum tau muab tso rau pem hauv ntej, nrog rau.
(1) nruab nrab thiab loj electrochemical zog cia fais fab nroj tsuag yuav tsum tsis txhob xaiv ternary lithium roj teeb, sodium-sulfur batteries, yuav tsum tsis txhob xaiv kev siv ntawm lwm yam fais fab roj teeb;
(2) kev xaiv thib ob ntawm kev siv cov roj teeb hluav taws xob, yuav tsum muaj kev tshuaj xyuas zoo ib yam thiab ua ke nrog cov ntaub ntawv traceability rau kev ntsuam xyuas kev nyab xeeb;
(3) lithium-ion roj teeb cov khoom siv chav tsev yuav tsum yog ib txheej txheej, nyiam dua siv prefabricated chav tsev hom.
Txawm hais tias nws yog lub ntiaj teb lub zog loj khaws cia siv ternary lithium roj teeb, los yog Tuam Tshoj tus tam sim no mainstay lithium hlau phosphate, lub zog cia tshuab yuav tsum rov qab mus rau qhov tseem ceeb tshaj plaws kev nyab xeeb, yog lub hauv paus ntawm txoj kev loj hlob.
Nyob rau hauv xyoo tas los no, lithium hlau phosphate thev naus laus zis tau ua tiav tag nrho, thiab ternary lithium roj teeb, lithium hlau phosphate roj teeb tsis muaj kev nyab xeeb, siab dua qhov kev nyab xeeb ntawm cov roj ntsha lead-acid. Hauv qab no yog kev sib piv ntawm cov khoom tseem ceeb ntawm lithium hlau phosphate cov ntaub ntawv thiab cov ntaub ntawv ternary.
Raws li koj paub, lub roj teeb uas siv hauv lub zog cia yuav tsum muaj lub neej ntev, kev nyab xeeb siab thiab tus nqi qis. Txawm hais tias lub zog ntom ntom ntawm lithium hlau phosphate roj teeb yog qhov tsawg, tab sis nws qhov kev ua haujlwm kub, qhov tseem ceeb tshaj plaws yog thermal stability yog kev ruaj ntseg zoo, lub neej ntev, thiab tam sim no, kuj hais lus, nws cov nqi qis dua ternary.
Nyob rau hauv cov nqe lus ntawm ternary cov ntaub ntawv, nws muaj siab gram muaj peev xwm thiab siab paug platform, uas txhais tau hais tias siab zog ceev. Nws qhov kev ua haujlwm kub qis yog qhov zoo dua, kev ua haujlwm kub kub yog qhov dav, thermal stability yog dav, kev nyab xeeb kev ua haujlwm kuj yog dav dav.
Los ntawm tag nrho cov kev xav, los ntawm lub zog cia yuav tsum muaj kev nyab xeeb, lub neej ntev, tus nqi qis, lithium hlau phosphate roj teeb pob yog qhov kev xaiv zoo tshaj plaws ntawm cov ntaub ntawv rau lub zog cia.
Lithium hlau phosphate roj teeb pob muaj qhov zoo ntawm kev nyab xeeb thiab kev ntseeg tau, lub neej ntev kev pab cuam, me me hneev taw, yooj yim khiav lag luam thiab tu. Cov khoom siv lithium hlau phosphate roj teeb ntawm tes, nws cov txheej txheem ntau lawm txais cov khoom siv tsis siv neeg, nrog cov khoom zoo sib xws, tsis muaj tawg thiab tsis muaj hluav taws, uas yog lub roj teeb zoo tshaj plaws hauv lithium roj teeb.
Them thiab tso tawm yog ob lub xeev ua haujlwm ntawm lithium roj teeb. Thaum lub lithium hlau phosphate roj teeb them thiab tawm, vim hais tias cov hlau ion oxidation muaj peev xwm tsis muaj zog, yuav tsis tso oxygen, nws yog ib qho nyuaj rau tshwm sim nrog cov electrolyte redox cov tshuaj tiv thaiv, uas ua rau cov lithium hlau phosphate roj teeb them thiab tso tawm txheej txheem nyob rau hauv ib tug. ib puag ncig nyab xeeb. Tsis tas li ntawd xwb, lithium hlau phosphate roj teeb nyob rau hauv lub loj multiplier tso tawm, thiab txawm overcharge thiab paug txheej txheem, nws yog ib qhov nyuaj rau tshwm sim nyob rau hauv lub nruj redox tshuaj tiv thaiv.
Nyob rau tib lub sij hawm, lithium nyob rau hauv lub de-embedding, lub lattice hloov thiaj li hais tias lub cell (qhov tsawg tshaj plaws chav tsev ntawm crystal muaj pes tsawg leeg) yuav nws thiaj li me me, uas tsuas yog offset qhov nce nyob rau hauv lub ntim ntawm carbon cathode nyob rau hauv cov tshuaj tiv thaiv, yog li ntawd. tus nqi thiab tso tawm ntawm lithium hlau phosphate roj teeb tuaj yeem tswj kev ruaj ntseg ntawm cov qauv ntawm lub cev, tshem tawm qhov muaj peev xwm nce ntim thiab qhov tshwm sim ntawm cov roj teeb tawg.
Qhov tshiab lithium-ion roj teeb thev naus laus zis kev txhim kho ntawm cov ntsiab lus ntawm kev nyab xeeb yog qhov tseem ceeb, cuam tshuam nrog kev txhim kho yav tom ntej ntawm cov nplai ntawm lithium lub sij hawm ntev zog. Lub zog cia lithium hlau phosphate roj teeb muaj kev nyab xeeb siab, tus nqi qis, kev ruaj ntseg yog lub hom phiaj kev loj hlob ntawm cov lag luam, tab sis kuj yog lub zog cia kev lag luam yog qhov xav tau ceev ceev ntawm kev taw qhia tseem ceeb ntawm kev tawm tsam.
