Hauv ib feeb, peb yuav paub tias txhua yam hauv ib txoj kev hnub ci teeb pom kev zoo lithium iron phosphate battery yog dab tsi
Lub roj teeb lithium iron phosphate rau txhua tus nyob hauv ib txoj kev hnub ci teeb yog lub roj teeb lithium ion siv lithium iron phosphate ua cov khoom siv cathode. Txhua qhov nyob hauv ib txoj kev hnub ci teeb yog ib hom kev ua haujlwm tau zoo hauv lub xeev lub teeb tsim los ntawm semiconductor PN kev sib tshuam uas tuaj yeem tso lub teeb nrog lub zog hluav taws xob tsis muaj zog. Nyob rau qee qhov kev cia siab rau yav tom ntej thiab qhov kev txhaj tshuaj tam sim no, nws txhaj qhov nyob hauv thaj tsam P thiab txhaj N Tom qab cov hluav taws xob hauv cheeb tsam kis mus rau thaj chaw nquag, lawv tau sib sau ua ke los ntawm hluav taws xob kom tso tawm photons, uas ncaj qha hloov hluav taws xob rau hauv lub zog hluav taws xob. Txhua qhov nyob hauv ib lub hnub ci txoj kev tsim teeb pom kev zoo yog lub xeev txias txias qhov chaw, uas muaj cov yam ntxwv ntawm kev tiv thaiv ib puag ncig, tsis muaj kuab paug, siv hluav taws xob tsawg, ua haujlwm siab lub teeb thiab lub neej ntev. Yog li ntawd, txhua qhov nyob hauv ib lub hnub ci txoj kev teeb pom kev yuav dhau los ua kev txuag hluav taws xob zoo tshaj plaws ntawm txoj kev teeb pom kev zoo. xaiv Lithium-ion roj teeb cathode cov khoom siv yog lithium cobalt, lithium manganate, lithium nickel, cov ntaub ntawv ternary, lithium iron phosphate, thiab lwm yam. Txhua qhov hauv ib lub hnub ci txoj kev teeb pom kev lag luam yog lub xeev txias txias qhov chaw, uas muaj cov yam ntxwv ntawm kev tiv thaiv ib puag ncig, muaj kuab paug -free, kev siv hluav taws xob tsawg, lub teeb pom kev zoo thiab lub neej ntev. Yog li ntawd, txhua qhov nyob hauv ib lub hnub ci txoj kev teeb pom kev yuav dhau los ua kev txuag hluav taws xob zoo tshaj plaws ntawm txoj kev teeb pom kev zoo. xaiv Ntawm lawv, lithium iron phosphate tam sim no yog cov khoom siv anode siv hauv feem ntau cov roj teeb lithium-ion. Hauv cov ntsiab lus ntawm cov khoom siv, lithium iron phosphate kuj tseem yog txheej txheem sib xyaw/deintercalation, uas yog tib yam li lithium cobalt thiab lithium manganate.
Cov roj teeb lithium iron phosphate yog cov roj teeb lithium thib ob. Ib lub hom phiaj tseem ceeb yog siv nws ua lub roj teeb muaj zog. Nws muaj qhov zoo tshaj li NI-MH thiab Ni-Cd roj teeb, thiab muaj kev them nqi siab thiab ua haujlwm tau zoo. Kev them nqi thiab tshem tawm qhov ua tau zoo tuaj yeem ncav cuag 90 nyob rau hauv kev tso tawm. Ntau tshaj li %, thaum cov roj teeb ua kua qaub ua rau txog 80 %.
Yim qhov zoo
1. Txhim kho kev nyab xeeb kev ua haujlwm
Cov po sib cog hauv lithium hlau phosphate crystal yog ruaj khov thiab nyuaj rau decompose. Txawm hais tias muaj qhov kub siab lossis ua kom sov dhau, nws yuav tsis tawg thiab ua kom sov zoo li cobalt lithium, lossis tsim cov tshuaj muaj zog oxidizing, yog li nws muaj kev nyab xeeb zoo. Daim ntawv tshaj tawm tau taw qhia tias hauv kev ua haujlwm tiag, tau kuaj pom me me kom hlawv hauv kev siv tshuaj kho mob lossis kev sim luv luv, tab sis tsis muaj kev tawg tshwm sim. Hauv qhov kev sim ntau dhau, Gaodianya muaj qhov tso tawm hluav taws xob ntau zaus ntau dua nws tus kheej thiab tau siv los them. Tseem muaj kev tawg. Txawm li cas los xij, nws qhov kev nyab xeeb them nyiaj tau dhau los tau zoo dua piv nrog cov kua hluav taws xob zoo tib yam lithium cobalt acid roj teeb.
2, kev txhim kho lub neej ncua
Lub voj voog lub neej ntawm cov roj teeb ua kua qaub yog li 300 zaug, siab tshaj plaws yog 500 zaug, lub neej voj voog ntawm lithium hlau phosphate fais fab roj teeb ntau dua 2000 zaug, thiab tus nqi them (5h tus nqi) tuaj yeem ncav cuag 2000 zaug. Cov roj teeb ua kua qaub uas zoo ib yam" tshiab ib nrab xyoo, qub ib xyoos ib xyoos, thiab kho ib nrab xyoo&";, lub sijhawm ntau tshaj yog 1 x 1.5 xyoo, thiab lub tswv yim theoretical lub neej ntawm lithium hlau roj teeb phosphate tuaj yeem ncav cuag 7 txog 8 xyoo nyob rau tib qhov xwm txheej. Siv rau hauv kev saib xyuas lub neej ua haujlwm ntawm cov roj teeb ua kua qaub, kev pabcuam lub neej ntawm cov roj teeb kua qaub-ntau dua 4 zaug ntawm cov roj teeb ua kua qaub. Kev tso tawm tam sim no tuaj yeem them sai thiab tso tawm tam sim no siab 2C. Nrog rau kev them nyiaj 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 mus txog 2C, tab sis cov roj teeb kua qaub tsis muaj qhov ua tau zoo.
3, ua haujlwm kub zoo
Qhov kub tshaj ntawm lithium iron phosphate tuaj yeem ncav cuag 350 ° C -500 ° C, thaum lithium manganate thiab lithium cobaltate tsuas yog nyob ib puag ncig 200 ° C. Kev ua haujlwm dav dav ntau yam kub (-20C-+75C), tiv taus kub, lithium iron phosphate cua sov siab tshaj li 350 ° C-500 ° C, thiab lithium manganate thiab lithium cobaltate tsuas yog nyob ib puag ncig 200 ° C.
4, muaj peev xwm loj
Nws lub peev xwm loj dua cov roj teeb zoo ib yam (lead-acid, thiab lwm yam). 5AH-1000AH (ib leeg)
5. Tsis muaj kev cuam tshuam kev nco
Cov roj teeb uas them rov qab tau ua haujlwm ntau zaus thiab tsis muaj roj teeb. Lub peev xwm yuav poob qis dua cov peev txheej ntsuas. Qhov tshwm sim no hu ua lub cim xeeb ua haujlwm. Piv txwv li, npib tsib xee-hlau hydride thiab roj teeb npib tsib xee-cadmium muaj cov cim xeeb, thaum cov roj teeb lithium hlau phosphate tsis ua. Txawm hais tias lub roj teeb lub xeev zoo li cas, lawv tuaj yeem siv ua ke nrog them nqi, thiab tsis tas yuav tso tawm ua ntej them nyiaj.
