Qhov zoo ntawm lithium hlau phosphate roj teeb
Lub npe tag nrho ntawm lithium hlau phosphate roj teeb yog lithium hlau phosphate lithium ion roj teeb, uas yog hais txog lithium ion roj teeb uas siv lithium hlau phosphate ua cov khoom zoo electrode. Muaj ntau yam khoom siv cathode rau cov roj teeb lithium-ion, feem ntau yog lithium cobalt oxide, lithium manganate, lithium nickelate, ternary cov ntaub ntawv, lithium hlau phosphate thiab lwm yam. Ntawm lawv, lithium cobalt oxide tam sim no yog cov khoom siv cathode siv hauv cov roj teeb lithium-ion feem ntau, thaum lwm cov ntaub ntawv cathode tsis tau tsim tawm hauv khw vim muaj ntau yam laj thawj. Lithium hlau phosphate kuj yog ib qho ntawm cov roj teeb lithium-ion. Nyob rau hauv cov nqe lus ntawm cov ntaub ntawv hauv paus ntsiab lus, lithium hlau phosphate kuj yog ib tug intercalation / deintercalation txheej txheem, uas yog raws nraim tib yam li lithium cobaltate thiab lithium manganate.
Cov roj teeb lithium hlau phosphate yog cov roj teeb lithium-ion thib ob. Ib qho ntawm nws cov kev siv tseem ceeb yog raws li lub roj teeb hluav taws xob. Nws muaj qhov zoo ntawm NI-MH thiab Ni-Cd roj teeb.
Advantage
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 sov lithium cobalt oxide los yog tsim cov oxidizing muaj zog, yog li nws muaj kev nyab xeeb zoo. Ib daim ntawv tshaj tawm tau taw qhia tias hauv kev ua haujlwm tiag tiag ntawm kev siv tshuaj acupuncture lossis kev sim luv luv, ib feem me me ntawm cov qauv tau pom tias hlawv, tab sis tsis muaj qhov tawg. Nyob rau hauv kev sim overcharge, high voltage them uas yog ob peb zaug siab dua tus kheej-tso tawm voltage tau siv, thiab nws tau pom tias tseem muaj qhov tshwm sim tawg. Txawm li cas los xij, nws txoj kev ruaj ntseg overcharge tau zoo dua qub piv nrog cov kua roj electrolyte lithium cobalt oxide zoo tib yam.
2, txhim kho lub neej ntev
“Lithium hlau phosphate roj teeb” yog 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 roj teeb lithium hlau phosphate muaj lub neej voj voog ntau dua 2000 zaug, thiab nws tuaj yeem siv tau 2000 zaug nrog txheem them nqi (5 teev tus nqi). Lead-acid roj teeb uas zoo ib yam yog “ib nrab xyoo tshiab, ib nrab xyoo, thiab ib nrab xyoo rau kev kho”, uas tuaj yeem siv li 1 txog 1.5 xyoo. Thaum siv nyob rau hauv tib yam kev mob, lithium hlau phosphate roj teeb muaj lub neej theoretical ntawm 7 mus rau 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. Nrog rau 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.
3, kev ua haujlwm kub 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, lithium hlau phosphate hluav taws xob cua sov ncov tuaj yeem ncav cuag 350 ℃ -500 ℃, thaum lithium manganate thiab lithium cobaltate tsuas yog nyob ib ncig ntawm 200 ℃.
4, muaj peev xwm loj
∩ Lub peev xwm ntawm cov roj teeb uas tuaj yeem rov qab tau sai dua yuav qis dua qhov muaj peev xwm ntsuas thaum lawv feem ntau them tag nrho thiab tsis tso tawm. 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 them thiab siv yam tsis tas yuav tso tawm ua ntej.
6, lub teeb nyhav
Lub ntim ntawm lithium hlau phosphate roj teeb ntawm tib lub specification thiab muaj peev xwm yog 2/3 ntawm lub ntim ntawm lead-acid roj teeb, thiab qhov hnyav yog 1/3 ntawm cov lead-acid roj teeb.
7, 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 (lub roj teeb nickel-hydrogen yuav tsum muaj cov hlau tsis tshua muaj), tsis muaj tshuaj lom (SGS tau lees paub), tsis muaj kuab paug, raws li European RoHS cov cai, thiab ib qho ntsuab ntsuab. roj teeb daim ntawv pov thawj. Yog li, vim li cas vim li cas cov 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 loj hlob high-tech hauv lub sijhawm “Kaum Tsib Tsib Xyoo” thiab tau dhau los ua qhov tseem ceeb hauv kev txhawb nqa thiab txhawb nqa lub tebchaws. Nrog rau Tuam Tshoj txoj kev nkag mus rau WTO, Tuam Tshoj cov khoom xa tawm ntawm 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 tsis muaj kuab lom.
Tab sis qee tus 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 lub tuam txhab cov txheej txheem tsim khoom tsis tu ncua thiab cov txheej txheem rov ua dua tshiab. Ib yam li ntawd, cov roj teeb lithium muaj 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 tuaj yeem tso rau hauv plua plav thiab dej. Lub roj teeb nws tus kheej yog ib hom tshuaj lom neeg, yog li nws muaj peev xwm tsim tau ob hom kev ua qias tuaj: ib qho yog cov pa phem ntawm cov txheej txheem excrement hauv kev tsim engineering; lwm qhov yog cov pa phem ntawm lub roj teeb tom qab nws tau muab pov tseg.
Cov roj teeb lithium hlau phosphate kuj tseem muaj lawv qhov tsis txaus: piv txwv li, kev ua haujlwm tsis zoo ntawm qhov kub thiab txias, tsis tshua muaj kais ntawm cov khoom siv cathode, thiab lub ntim ntawm lithium hlau phosphate roj teeb ntawm qhov sib npaug ntawm lub peev xwm loj dua li ntawm lithium-ion roj teeb xws li lithium. cobalt oxide, yog li nws tsis muaj qhov zoo dua hauv 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 roj teeb.
