Dab tsi yog qhov zoo ntawm lub hnub ci LiFePo4 roj teeb?

Kev sib xyaw ntawm SolarLiFePo 4roj teeb Qhov tshwj xeeb feature ntawmHnub ci LiFePo4 roj teeb(lithium hlau phosphate roj teeb) yog siv cov txiv ntseej siv lead ua qauv, siv lead ua yog cov duab tom qab crystallization, muab faib ua ionic / molecular / atomic / hlau siv lead ua, lithium-ion roj teeb ionic siv lead ua yog muab los ntawm nws cov khoom siv cathode hauv kev npaj ntawm ionic compounds. nyob rau hauv cov duab ntawm lub ntsiab lus, uas yog, los ntawm qhov zoo thiab tsis zoo ion pawg nyob rau hauv ib tug tej yam kev faib ua feem ntawm cov siv lead ua tsim los ntawm ionic bonding. Feem ntau hais lus, ionic crystals yog nkig thiab tawv, muaj cov yam ntxwv ntawm melting thiab boiling point, thiab muaj peev xwm ua hluav taws xob thaum molten los yog yaj. Lub hauv paus ntawm tag nrho cov lithium-ion roj teeb, suav nrog lithium hlau phosphate technology, yog ionic conductivity. Feem ntau ntawm cov qauv siv lead ua sab hauv ntawm lithium-ion roj teeb cathode siv "spinel qauv" kev npaj, lithium manganate, lithium cobaltate, ternary lithium roj teeb yog li, cov qauv no muaj yim lub cubic me me uas muaj cov hlwb spinel (cov units uas ua rau li cov siv lead ua, tuaj yeem nkag siab tias yog cov hlwb siv lead ua), cov hlwb tom qab ntawd ua ke rau hauv cov qauv siv lead ua octahedral. Nyob rau hauv sib piv, cov txiv ntseej qauv ntawm lithium hlau phosphate crystals yog luv kab. Cov qauv spinel ntawm peb lub roj teeb lithium saum toj no muaj lawv tus kheej yam ntxwv. Lithium cobalt-acid roj teeb muaj kev ua tau zoo tag nrho, tab sis tsis tshua muaj peev xwm thiab teeb meem kev nyab xeeb, thiab kim dua rau kev ua lag luam; lithium manganate roj teeb vim muaj kev nkag tau zoo rau cov ntaub ntawv, tus nqi qis thiab kev nyab xeeb, tab sis kev ua haujlwm tsis zoo thiab kev cia khoom; ternary lithium roj teeb yog npaj los kho qhov tsis txaus ntawm ob, lub peev xwm tau nce, thiab kev ruaj ntseg ntawm cov qauv tau txhim kho kev nyab xeeb, tab sis tus nqi tseem kim heev, vim nws kuj yuav tsum muaj cov khoom siv raw cobalt. Qhov tsis zoo ntawm spinellithium-ion roj teebyog tias lub hwj chim tsis loj, tsis haum rau qhov loj. Dab tsi yog cov yam ntxwv ntawm Solar LiFePo4 roj teeb? Hnub ci LiFePo4 roj teeb thev naus laus zis nta thiab kev lag luam, ntawm qhov tod tes, tsuas yog txoj cai rau lub tsev lub zog cia khoom lag luam scenario. Tshwj xeeb. 1. hnub ci LiFePo4 roj teeb voltage yog nruab nrab: nominal voltage 3.2V, termination charging voltage 3.6V, termination discharge voltage 2.0V. 2. muaj peev xwm theoretical siab, nrog lub zog ceev ntawm 170mAh / g. 3. zoo thermal stability thiab kub tsis kam. 4. nruab nrab lub zog cia, cov khoom siv cathode sib haum nrog cov tshuab electrolyte feem ntau. 5. txiav tawm qhov hluav taws xob ntawm 2.0V, uas tuaj yeem tso tawm ntau lub peev xwm, loj thiab sib npaug tawm. 6. Cov yam ntxwv ntawm lub platform zoo, thiab qhov sib npaug ntawm nws qhov kev them nyiaj thiab kev tawm hluav taws xob hluav taws xob tuaj yeem nyob ze rau ntawm lub zog tswj hwm. Cov txheej txheem saum toj no ua rau lub zog siab thiab kev nyab xeeb zoo tshaj plaws kom ua tiav, uas txhawb nqa daim ntawv thov ntawm LiFePo4 roj teeb loj. Ntxiv nrog rau cov yam ntxwv ntawm kev ua haujlwm, LiFePo4 roj teeb muaj ob qhov kev lag luam zoo: 1. cov khoom siv pheej yig, cov khoom siv ntau; 2. tsis muaj cov khoom muaj txiaj ntsig zoo, tsis muaj tshuaj lom, yog cov khoom lag luam zoo ib puag ncig. Qhov no ua rau lithium hlau phosphate roj teeb daim ntawv thov nyob rau hauv lub tam sim no lub zog tshiab tsheb lag luam ci, thiab dhau los ua lub zog nyiam cia tshuab rau lub tsev hnub ci cia systems. Hnub Ci Lithium Hlau Phosphate thiab Lithium Manganate, Lithium Cobaltate, Ternary Lithium Roj Teeb Sib Piv LiFePo4 roj teeb thiab lithium manganate, lithium cobaltate, lithium ternary roj teeb yog tib ceg ntawm lithium-ion roj teeb, nws qhov kev ua tau zoo yog siv rau hnub ci zog siv, uas yog hu ua hnub ci lithium hlau phosphate roj teeb, tseem hu ua lithium-hlau roj teeb. Yog li ntawd, qhov zoo ntawm hnub ci lithium hlau phosphate roj teeb feem ntau yog hais txog nws qhov kev sib piv nrog rau lwm cov roj teeb hauv kev siv lub zog cia. Hauv qhov kev nkag siab no, nws feem ntau yuav sib piv nws cov txiaj ntsig zoo nrog ternary lithium roj teeb thiab cov roj ntsha lead-acid. Ua ntej, qhov zoo ntawm qhov kub-kub kuj piv nrog ternary lithium roj teeb. SolarLiFePo4batteries muaj qhov ua tau zoo ntawm qhov kub thiab txias, tuaj yeem tiv taus qhov kub thiab txias ntawm 350 ° C ~ 500 ° C, thaum lithium manganate / lithium cobaltate feem ntau tsuas yog li 200 ° C, hloov cov ntaub ntawv lithium ternary lithium roj teeb kuj tseem yuav luag 200 ° C decomposition. Qhov thib ob, peb ntawm "cov neeg laus" - qhov txiaj ntsig zoo ntawm lub neej ntev. Cov roj teeb lithium hlau phosphate dua li cov roj teeb lead-acid thiab ternary lithium roj teeb muaj lub neej ntev. Lead-acid roj teeb nyob rau hauv "ntev lub neej" tsuas yog hais txog 300 zaug, mus txog 500 zaug; ternary lithium roj teeb theoretically mus txog 2000 zaug, daim ntawv thov tiag tiag txog li 1000 zaug lub peev xwm yuav lwj mus rau 60%; thiab lithium hlau phosphate roj teeb lub neej tiag tiag uas 2000 zaug, thaum tseem muaj 95% ntawm lub peev xwm, lub tswv yim ntawm lub neej voj voog ncav cuag ntau dua 3000 zaug. Piv nrog Lead-acid roj teeb muaj ntau yam zoo 1. Muaj peev xwm loj.Monomer tuaj yeem ua rau 5Ah ~ 1000 Ah (1 Ah = 1000m Ah), thaum lub roj teeb lead-acid 2V monomer feem ntau yog 100Ah ~ 150 Ah, qhov hloov pauv me me. 2. Lub teeb yuag.Tib lub peev xwm ntawm hnub ci LiFePo4 roj teeb ntim yog 2/3 ntawm qhov ntim ntawm cov roj ntsha lead-acid, qhov hnyav yog 1/3 ntawm tom kawg. 3. Muaj peev xwm them sai sai.Hnub ci LiFePo4 roj teeb them tam sim no mus txog 1C, kom ua tiav tus nqi loj ntawm kev them nyiaj; txhuas-acid roj teeb tam sim no feem ntau xav tau ntawm 0.1C ~ 0.2C, tsis tuaj yeem ncav cuag kev them nyiaj ceev. 4. Kev tiv thaiv ib puag ncig. Cov roj teeb txhuas-acid muaj nyob hauv ntau cov hlau hnyav - txhuas, ua kua dej pov tseg, thaum lub hnub ci LiFePo4 roj teeb tsis muaj cov hlau hnyav, tsis muaj kuab paug hauv kev tsim khoom thiab siv. 5. Tus nqi siab ua haujlwm.Txawm hais tias cov roj teeb lead-acid vim nws cov khoom pheej yig, tus nqi tau los yog qis dua li lub hnub ci LiFePo4 roj teeb, tab sis nyob rau hauv kev pab cuam lub neej thiab niaj hnub saib xyuas kev lag luam yog qis dua lub hnub ci LiFePo4 roj teeb. Cov txiaj ntsig ntawm daim ntawv thov tau qhia tias: hnub ci lithium hlau phosphate roj teeb yog ntau tshaj plaub npaug ntawm cov nqi ntawm cov roj ntsha lead-acid. Hnub ci LiFePo4battery daim ntaub ntawv yog yeej nyob rau hauv cov kev taw qhia ntawmlub zog cia, uas tau txiav txim siab los ntawm ntau yam zoo qhia nyob rau hauv cov kev sib piv saum toj no, yog tias lub zog sib npaug thiab tom qab ntawd ua qee yam los txhim kho, lithium yeeb koob hluav taws xob phosphate yuav dhau los ua tustsev neeg lub zog cia xaiv!
