8 qhov zoo yog LFP roj teeb

Qhov zoo electrode ntawm lithium ion roj teeb yog ua los ntawm cov khoom siv lithium hlau phosphate, uas muaj cov txiaj ntsig zoo ntawm kev nyab xeeb kev ua haujlwm thiab lub neej voj voog. Cov no yog ib qho tseem ceeb tshaj plaws kev ntsuas ntawm lub hwj chim roj teeb. Lifepo4 roj teeb 1C them thiab tso tawm lub neej mus txog 2000 zaug, puncture tsis tawg, overcharge tsis yooj yim rau hlawv thiab tawg. Lithium hlau phosphate cathode cov ntaub ntawv ua kom muaj peev xwm loj lithium-ion roj teeb yooj yim siv hauv cov koob.

Lithium Hlau Phosphate Cathode Khoom

Lifepo4 roj teeb hais txog lub roj teeb lithium ion siv lithium hlau phosphate ua cov khoom siv electrode zoo. Lithium-ion roj teeb cathode cov ntaub ntawv feem ntau suav nrog lithium cobalt oxide, lithium manganate, lithium nickelate, ternary cov ntaub ntawv, thiab lithium hlau phosphate. Ntawm lawv, lithium cobalt oxide yog cov khoom siv cathode siv nyob rau hauv feem ntau lithium-ion roj teeb. Nyob rau hauv txoj cai, lithium hlau phosphate kuj yog ib qho txheej txheem intercalation thiab deintercalation. Lub hauv paus ntsiab lus no yog tib yam li lithium cobalt oxide thiab lithium manganese oxide.

Lifepo4 roj teeb kom zoo dua

1. Kev them nyiaj siab thiab tso tawm ua haujlwm

Lub roj teeb Lifepo4 yog lithium ion thib ob roj teeb. Ib qho kev siv tseem ceeb yog rau cov roj teeb fais fab. Nws muaj qhov zoo tshaj plaws ntawm nickel-hlau hydride thiab nickel-cadmium roj teeb. Lifepo4 roj teeb muaj kev them nqi siab thiab kev ua haujlwm tawm, uas tuaj yeem ncav cuag ntau dua 90% hauv lub xeev tawm, thaum lub roj teeb txhuas-acid yog li 80%.

2. Lifepo4 roj teeb muaj kev ruaj ntseg zoo

PO daim ntawv cog lus nyob rau hauv lithium hlau phosphate siv lead ua yog ruaj khov thiab nyuaj rau decompose. Txawm tias nyob rau hauv qhov kub thiab txias los yog overcharge, nws yuav tsis tawg los yog kub lithium cobalt oxide, thiab nws yuav tsis tsim muaj zog oxidizing tshuaj, yog li nws muaj kev ruaj ntseg zoo.

Nws tau tshaj tawm tias hauv kev ua haujlwm tiag tiag, qee qhov piv txwv tau pom tias kub hnyiab hauv acupuncture lossis luv luv-circuit test, tab sis tsis muaj qhov tawg. Nyob rau hauv qhov kev sim overcharge, ib tug high voltage nqi uas yog ob peb zaug siab dua tus kheej-tso tawm voltage yog siv, thiab nws tau pom tias tseem muaj ib tug blasting tshwm sim. Txawm li cas los xij, nws txoj kev ruaj ntseg overcharge tau zoo dua qub piv rau cov kua roj electrolyte lithium cobalt oxide zoo tib yam.

3. Lifepo4 roj teeb muaj lub neej voj voog ntev

Lifepo4 roj teeb hais txog lub roj teeb lithium ion siv lithium hlau phosphate ua cov khoom siv electrode zoo.

Lub voj voog lub neej ntawm lub neej ntev ntawm cov roj ntsha lead-acid yog li 300 zaug, txog li 500 zaug. Lub neej voj voog ntawm lithium hlau phosphate roj teeb lub zog yog ntau tshaj 2000 zaug, thiab tus qauv nqi (5 teev tus nqi) tuaj yeem ncav cuag 2000 zaug.

Cov roj ntsha lead-acid zoo tib yam “ib nrab xyoo tshiab, ib nrab xyoo, thiab ib nrab xyoo rau kev saib xyuas” tuaj yeem ncav cuag li 1 txog 1.5 xyoo, thaum lub roj teeb lifepo4 yuav muaj lub neej theoretical ntawm 7 mus rau 8 xyoo thaum siv. nyob rau hauv tib yam mob.

Kev txiav txim siab dav dav, theoretically tus nqi-kev ua tau zoo piv yog ntau tshaj plaub npaug ntawm cov roj ntsha lead-acid. Kev tawm tam sim no tuaj yeem siv 2C siab tam sim no kom them sai sai thiab tawm. Nyob rau hauv lub charger tshwj xeeb, lub roj teeb tuaj yeem them tag nrho hauv 1.5 feeb ntawm 1.5C, thiab qhov pib tam sim no tuaj yeem ncav cuag 2C, thaum lub roj teeb txhuas-acid tsis muaj qhov ua tau zoo.

4. Kev ua haujlwm kub zoo

Lub ncov kub 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), kub tsis kam, lithium hlau phosphate hluav taws xob cua sov ncov tuaj yeem ncav cuag 350 ° C-500 ° C, thaum lithium manganate thiab lithium cobaltate tsuas yog nyob ntawm 200 ° C.

5. Lifepo4 roj teeb muaj peev xwm

Nws muaj peev xwm loj dua li cov roj teeb zoo tib yam (lead-acid, thiab lwm yam). Lub peev xwm monomer yog 5AH-1000AH.

6. Tsis nco qab

Thaum lub roj teeb rechargeable feem ntau tsis tso tawm tag nrho, lub peev xwm yuav sai sai poob qis dua lub peev xwm. Qhov tshwm sim no hu ua lub cim xeeb nyhuv. Lub cim xeeb yog tib yam li Ni-MH thiab Ni-Cd roj teeb, tab sis lub roj teeb lifepo4 tsis muaj qhov tshwm sim no. Txawm hais tias lub roj teeb nyob hauv lub xeev dab tsi, nws tuaj yeem raug them thiab siv yam tsis tau tso tawm thiab rov them dua.

7. Lub teeb yuag ntawm lifepo4 roj teeb

Lub lifepo4 roj teeb ntawm tib lub specification thiab muaj peev xwm yog 2/3 ntawm lub ntim ntawm cov lead-acid roj teeb, thiab qhov hnyav yog 1/3 ntawm lead-acid roj teeb.

8. Lifepo4 roj teeb yog ib puag ncig tus phooj ywg

Lub roj teeb feem ntau suav hais tias tsis muaj cov hlau hnyav thiab cov hlau tsis tshua muaj (cov roj teeb nickel-hydrogen yuav tsum muaj cov hlau tsawg), tsis muaj tshuaj lom (SGS ntawv pov thawj), tsis muaj kuab paug, raws li European RoHS cov cai, thiab yog 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 kev xav txog ib puag ncig. Yog li ntawd, thaum lub sij hawm “Tsib Hlis Tsib Xyoo” lub sij hawm, lub roj teeb tau muab tso rau hauv “863” lub teb chaws high-tech txoj kev npaj thiab tau dhau los ua ib qho tseem ceeb hauv lub teb chaws kev txhawb nqa thiab kev txhawb nqa project.

Nrog rau kuv lub teb chaws nkag mus rau WTO, kuv lub teb chaws kev 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.

Kev ua haujlwm ntawm cov roj teeb lithium-ion feem ntau yog nyob ntawm cov khoom zoo thiab tsis zoo. Lithium hlau phosphate yog cov khoom siv roj teeb lithium uas tau tshwm sim hauv xyoo tas los no. Nws kev nyab xeeb kev ua tau zoo thiab lub voj voog lub neej tsis sib xws los ntawm lwm cov ntaub ntawv. Qhov tseem ceeb tshaj plaws kev qhia ntawm lub roj teeb.

Lifepo4 roj teeb muaj qhov zoo ntawm cov khoom tsis muaj tshuaj lom, tsis muaj kuab paug, kev nyab xeeb zoo, ntau yam khoom siv raw, tus nqi qis thiab lub neej ntev. Nws yog cov khoom siv cathode zoo tshaj plaws rau lub cim tshiab ntawm lithium-ion roj teeb.
