Qhov zoo ntawm lithium hlau phosphate roj teeb

1. Kev txhim kho kev nyab xeeb kev ua haujlwm

PO daim ntawv cog lus nyob rau hauv lithium hlau phosphate siv lead ua yog ruaj khov thiab nyuaj rau decompose.Txawm tias qhov kub thiab txias, nws yuav tsis tawg thiab ua kom muaj cua sov zoo li lithium cobalt oxide lossis tsim cov oxidizing muaj zog, yog li nws muaj kev nyab xeeb zoo.Ib daim ntawv tshaj tawm tau taw qhia tias nyob rau hauv qhov kev ua haujlwm tiag tiag, qee qhov qauv me me tau pom tias kub hnyiab hauv acupuncture lossis kev sim luv luv, tab sis tsis muaj qhov tawg.tawg phenomenon.Txawm li cas los xij, nws txoj kev nyab xeeb overcharge tau zoo dua qub piv nrog cov kua roj electrolyte lithium cobalt oxide zoo tib yam.

2. Kev txhim kho lub neej ntev

Lithium hlau phosphate roj teeb hais txog lithium ion roj teeb uas siv lithium hlau phosphate ua cov khoom siv electrode zoo.

Lub neej voj voog ntawm lub neej ntev ntawm cov roj ntsha lead-acid yog li 300 zaug, thiab qhov siab tshaj plaws yog 500 zaug, thaum lub neej voj voog ntawm lithium hlau phosphate roj teeb muaj peev xwm ncav cuag ntau dua 2,000 zaug, thiab tus qauv them nqi (5-teev tus nqi) siv tau mus txog 2,000 zaug.Lub roj teeb txhuas-acid zoo tib yam yog "ib nrab xyoo tshiab, ib nrab xyoo, thiab kev tu thiab tu ib nrab xyoo", uas yog 1 ~ 1.5 xyoo feem ntau, thiab lithium hlau phosphate roj teeb yog siv nyob rau hauv tib lub sijhawm, lub neej theoretical yuav ncav cuag 7 ~ 8 xyoo.Kev txiav txim siab dav dav, qhov kev ua tau zoo-tus nqi piv yog theoretically ntau dua 4 npaug ntawm cov roj ntsha lead-acid.Kev tso tawm siab tam sim no tuaj yeem them sai sai thiab tso tawm siab tam sim no 2C.Nyob rau hauv lub charger tshwj xeeb, lub roj teeb tuaj yeem them tag nrho hauv 40 feeb ntawm 1.5C them, thiab qhov pib tam sim no tuaj yeem ncav cuag 2C, tab sis cov roj teeb lead-acid tsis muaj qhov ua tau zoo no.

3. Kev kub siab ua haujlwm zoo

Qhov hluav taws xob cua sov ncov ntawm lithium hlau phosphate tuaj yeem ncav cuag 350 ℃ -500 ℃, thaum lithium manganate thiab lithium cobaltate tsuas yog nyob ib ncig ntawm 200 ℃.Kev khiav hauj lwm kub ntau (-20C-75C), nrog rau kub tsis kam, hluav taws xob cua sov ncov ntawm lithium hlau phosphate tuaj yeem ncav cuag 350 ℃ -500 ℃, thaum lithium manganate thiab lithium cobaltate tsuas yog nyob ib ncig ntawm 200 ℃.

4. Muaj peev xwm loj

Cov roj teeb feem ntau ua haujlwm nyob rau hauv cov xwm txheej uas tau them tag nrho, thiab lub peev xwm yuav sai sai poob qis dua lub peev xwm.Qhov tshwm sim no hu ua lub cim xeeb nyhuv.Zoo li nickel-hlau hydride thiab nickel-cadmium roj teeb, muaj kev nco, tab sis lithium hlau phosphate roj teeb tsis muaj qhov tshwm sim no.Txawm hais tias lub roj teeb nyob hauv lub xeev dab tsi, nws tuaj yeem siv tau txhua lub sijhawm yam tsis tas yuav tso tawm ua ntej them nyiaj.

5. Lub teeb nyhav

Lub ntim ntawm lithium hlau phosphate roj teeb nrog tib lub ntsiab lus thiab lub peev xwm yog 2/3 ntawm lub ntim ntawm cov hmoov lead-acid roj teeb, thiab qhov hnyav yog 1/3 ntawm cov roj lead-acid.

6. Kev tiv thaiv ib puag ncig

Cov roj teeb lithium hlau phosphate feem ntau suav hais tias tsis muaj cov hlau hnyav thiab cov hlau tsis tshua muaj (nickel-hlau hydride roj teeb xav tau cov hlau tsis tshua muaj), tsis muaj tshuaj lom (SGS tau lees paub), tsis muaj kuab paug, ua raws li European RoHS cov cai, thiab yog qhov tseeb. ntsuab roj teeb daim ntawv pov thawj.Yog li ntawd, vim li cas vim li cas lub roj teeb lithium tau nyiam los ntawm kev lag luam feem ntau yog vim muaj kev tiv thaiv ib puag ncig.Yog li ntawd, lub roj teeb tau suav nrog hauv "863" lub teb chaws txoj kev npaj tsim kho high-tech hauv lub sijhawm "Kaum Tsib Tsib Xyoo" lub sijhawm, thiab tau dhau los ua ib txoj haujlwm tseem ceeb uas tau txhawb nqa thiab txhawb nqa los ntawm lub xeev.Nrog rau Tuam Tshoj txoj kev nkag mus rau WTO, cov khoom ntim ntawm Tuam Tshoj cov tsheb kauj vab hluav taws xob yuav nce sai, thiab cov tsheb kauj vab hluav taws xob nkag mus rau Tebchaws Europe thiab Tebchaws Meskas yuav tsum tau nruab nrog cov roj teeb uas tsis muaj kuab paug.

Txawm li cas los xij, qee cov kws tshaj lij tau hais tias kev ua qias tuaj ib puag ncig los ntawm cov roj ntsha lead-acid feem ntau tshwm sim hauv cov txheej txheem tsim khoom tsis yog txheej txheem thiab cov txheej txheem rov ua haujlwm ntawm cov lag luam.Ib yam li ntawd, cov roj teeb lithium yog nyob rau hauv lub zog tshiab kev lag luam, tab sis nws tsis tuaj yeem zam qhov teeb meem ntawm cov hlau hnyav hnyav.Lead, arsenic, cadmium, mercury, chromium, thiab lwm yam hauv kev ua cov khoom siv hlau yuav raug tso rau hauv plua plav thiab dej.Lub roj teeb nws tus kheej yog cov tshuaj lom neeg, yog li nws yuav ua rau muaj ob hom kev ua qias tuaj: ib qho yog cov txheej txheem pov tseg cov pa phem hauv qhov project ntau lawm;lwm yam yog lub roj teeb muaj kuab paug tom qab scrapping.

Cov roj teeb lithium hlau phosphate kuj muaj lawv qhov tsis txaus: piv txwv li, kev ua haujlwm kub tsis zoo, qhov ntom ntom ntawm cov khoom siv electrode tsawg tsawg, thiab lub ntim ntawm lithium hlau phosphate roj teeb uas muaj peev xwm sib npaug yog loj dua li ntawm lithium ion roj teeb xws li lithium. cobalt oxide, yog li nws tsis muaj qhov zoo ntawm cov roj teeb micro.Thaum siv cov roj teeb hluav taws xob, cov roj teeb lithium hlau phosphate, zoo li lwm cov roj teeb, yuav tsum tau ntsib teeb meem ntawm cov roj teeb sib xws.
