Qhov zoo thiab qhov tsis zoo ntawm Lithium Iron Phosphate Batteries

Lithium hlau phosphate roj teeb kuj yog hom roj teeb lithium. Ib yam li cov roj teeb uas siv hauv peb lub xov tooj ntawm tes, cov khoom siv hluav taws xob zoo ntawm lithium hlau phosphate roj teeb feem ntau yog cov phosphorus, acid, hlau, thiab lithium. Qee tus neeg kuj hu nws lithium hlau (LiFe) lub zog roj teeb.

Qhov zoo:
1: Lub neej ntawm hlau phosphate roj teeb, raws li tus qauv them nqi, tus lej ntawm cov voj voog tuaj yeem ncav cuag ntau dua 2, 000 zaug. Tus nqi thiab tawm lub voj voog lub neej ntawm cov roj teeb lithium zoo ib yam yog ntau tshaj 500 zaug. Thiab nws lub zog cia tus nqi yuav qis dua thiab qis dua thaum lub sijhawm dhau mus.
2: Muaj peev xwm loj thiab siab ceev. Lithium hlau phosphate roj teeb muaj peev xwm cia 2 mus rau 3 zaug siab dua lithium roj teeb ntawm tib lub ntim. .
3: 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 roj teeb txhuas-acid, thiab nws qhov hnyav yog 1/3 ntawm lub roj teeb txhuas-acid.
4: Muaj peev xwm tsis tu ncua. Kuv ntseeg tias txhua tus neeg yuav ntsib cov teeb meem zoo li no, uas yog, peb lub xov tooj ntawm tes roj teeb, roj teeb khoos phis tawj, thiab txawm tias cov roj teeb tsheb hluav taws xob. Tom qab lawv tau siv rau ib lub sijhawm, peb yuav pom tias cov hluav taws xob khaws cia hauv lawv ua tsawg dua. Qhov no yog vim hais tias yog cov roj teeb zoo tib yam tsis tau them tag nrho rau lub sijhawm ntev, lub roj teeb lub peev xwm yuav txo qis sai. Cov yam ntxwv ntawm cov roj teeb lithium phosphate yog tias lawv tuaj yeem siv tau txhua lub sijhawm! Thiab nws yuav tsis cuam tshuam nws lub peev xwm cia.
5: Ntsuab thiab ib puag ncig tus phooj ywg. Cov roj teeb lithium hlau phosphate muaj ib puag ncig kev ua haujlwm uas lwm cov roj teeb tsis muaj vim lawv tsis muaj cov hlau hnyav. Yog li ntawd, txoj kev loj hlob tau txhawb nqa los ntawm lub teb chaws tau siv rau hauv kev lag luam tsheb kauj vab lossis hluav taws xob tsheb.
6: Kev kub siab ua haujlwm zoo. Qhov hluav taws xob cua sov ncov ntawm lithium hlau phosphate tuaj yeem ncav cuag 350 degree -500 degree, thaum lub ncov tus nqi ntawm lithium manganate thiab lithium cobalt oxide tsuas yog nyob ib ncig ntawm 200 degree. Nws muaj qhov kub thiab txias ua haujlwm ntau (-20C--75C) thiab muaj qhov kub tsis kam. Lub ncov tus nqi ntawm lithium hlau phosphate hluav taws xob cua sov tuaj yeem ncav cuag 350 degree -500 degree, thaum lithium manganate thiab lithium cobalt oxide tsuas yog nyob ib ncig ntawm 200 degree.

Qhov tsis zoo:Kev ua haujlwm tsis zoo ntawm qhov kub thiab txias, tsis tshua muaj kais ntom ntawm cov khoom siv cathode, thiab lub ntim ntawm lithium hlau phosphate roj teeb ntawm tib lub peev xwm loj dua li ntawm lithium-ion roj teeb xws li lithium cobalt oxide, yog li nws tsis muaj txiaj ntsig zoo hauv cov roj teeb micro. Thaum siv cov roj teeb fais fab, cov roj teeb lithium hlau phosphate, zoo li lwm cov roj teeb, yuav tsum tau ntsib teeb meem roj teeb.
1. Thaum lub sij hawm sintering txheej txheem thaum lub sij hawm kev npaj ntawm lithium hlau phosphate, hlau oxide tej zaum yuav raug txo mus rau elemental hlau nyob rau hauv ib tug high-kub txo qhov cua. Elemental hlau tuaj yeem ua rau micro-short circuits hauv cov roj teeb thiab yog cov khoom tseem ceeb tshaj plaws hauv cov roj teeb.
2. Lithium hlau phosphate muaj qee qhov kev ua haujlwm tsis zoo, xws li cov kais dej tsis tshua muaj zog thiab compaction ceev, uas ua rau cov roj teeb lithium-ion tsawg zog. Kev ua haujlwm kub qis yog qhov tsis zoo, thiab txawm tias nanonization thiab carbon txheej tsis daws qhov teeb meem no.
3. Cov nqi ntawm cov khoom siv thiab cov nqi tsim khoom ntawm cov roj teeb yog siab, lub roj teeb tawm los qis, thiab qhov sib xws tsis zoo. Txawm hais tias cov nanonization thiab carbon txheej ntawm lithium hlau phosphate txhim kho cov khoom siv hluav taws xob, nws kuj ua rau lwm yam teeb meem, xws li txo qis zog, nce nqi synthesis, kev ua haujlwm tsis zoo electrode, thiab hnyav ib puag ncig. Txawm hais tias cov tshuaj lom neeg Li, Fe thiab P hauv lithium hlau phosphate muaj ntau thiab cov nqi qis, tus nqi ntawm cov khoom npaj lithium hlau phosphate tsis tsawg. Txawm hais tias thawj zaug kev tshawb fawb thiab kev tsim cov nqi raug tshem tawm, cov txheej txheem nqi ntawm cov khoom siv ntxiv rau qhov siab Tus nqi ntawm kev npaj cov roj teeb yuav ua rau tus nqi kawg ntawm ib chav tsev ntawm lub zog cia siab dua.
4. Cov khoom sib xws tsis zoo. Tam sim no, tsis muaj lithium hlau phosphate khoom Hoobkas hauv Suav teb uas tuaj yeem daws qhov teeb meem no. Los ntawm qhov kev xav ntawm kev npaj cov khoom, cov tshuaj synthesis ntawm lithium hlau phosphate yog ib tug complex multi-phase cov tshuaj tiv thaiv, nrog rau cov khoom theem phosphate, hlau oxide thiab lithium ntsev, ntxiv rau carbon precursor thiab txo cov roj theem. Nyob rau hauv cov txheej txheem tshuaj tiv thaiv complex, nws yog ib qho nyuaj los xyuas kom meej qhov sib xws ntawm cov tshuaj tiv thaiv.
