Lifepo4 muaj kev ua haujlwm zoo electrochemical nrog kev ua haujlwm qis.Qhov no yog ua tau nrog nano-scale phosphate cathode khoom.Cov txiaj ntsig tseem ceeb yog qhov ntsuas siab tam sim no thiab lub neej voj voog ntev, ntxiv rau qhov zoo thermal stability, txhim khu kev ruaj ntseg thiab ua siab ntev yog tias tsim txom.
Li-phosphate muaj kev tiv thaiv ntau dua rau cov nqi them tag nrho thiab tsis tshua muaj kev ntxhov siab dua li lwm lub tshuab lithium-ion yog tias khaws cia ntawm qhov hluav taws xob siab rau lub sijhawm ntev.Raws li kev lag luam tawm, nws qhov qis nominal voltage ntawm 3.2V / cell txo cov zog tshwj xeeb hauv qab ntawm cobalt-blended lithium-ion.Nrog rau feem ntau ntawm cov roj teeb, qhov kub thiab txias txo qhov kev ua tau zoo thiab qhov ntsuas kub siab ua kom lub neej ua haujlwm, thiab Li-phosphate tsis muaj qhov tshwj xeeb.Li-phosphate muaj qhov tso tawm tus kheej ntau dua li lwm cov roj teeb Li-ion, uas tuaj yeem ua rau muaj teeb meem nrog kev laus.Qhov no tuaj yeem txo tau los ntawm kev yuav cov hlwb zoo thiab/lossis siv cov khoom siv hluav taws xob zoo tswj, ob qho tib si ua rau tus nqi ntawm cov pob.
Li-phosphate feem ntau yog siv los hloov cov roj ntsha lead acid oob khab.Nrog plaub li-phosphate hlwb nyob rau hauv series, txhua lub xov tooj saum toj kawg nkaus ntawm 3.60V, uas yog qhov tseeb tag nrho cov nqi hluav taws xob.Nyob rau lub sijhawm no, tus nqi yuav tsum raug txiav tawm tab sis tus nqi topping tseem txuas ntxiv thaum tsav tsheb.Li-phosphate yog kam rau ib co overcharge;Txawm li cas los xij, ua kom qhov hluav taws xob ntawm 14.40V rau lub sijhawm ntev, raws li cov tsheb feem ntau ua rau kev tsav tsheb ntev, tuaj yeem ntxhov siab Li-phosphate.Kev ua haujlwm txias txias pib tuaj yeem yog qhov teeb meem nrog Li-phosphate ua lub roj teeb pib.
