LiFePO4 (Lithium Iron Phosphate) yog hais txog ib hom lithium-ion roj teeb chemistry, tab sis nws tsis zoo ib yam li "lithium roj teeb."
Cov roj teeb lithium-ion yog tsev neeg ntawm cov roj teeb uas siv tau uas siv lithium ua ib qho ntawm lawv cov khoom tseem ceeb. Lawv tuaj nyob rau hauv ntau yam chemistry, txhua tus muaj nws tus kheej cov yam ntxwv, qhov zoo, thiab qhov tsis zoo. LiFePO4 yog ib qho chemistry.
LiFePO4 roj teeb paub txog lawv txoj kev ruaj ntseg, kev nyab xeeb, thiab lub neej voj voog ntev. Lawv feem ntau siv rau hauv cov ntawv thov uas muaj kev nyab xeeb thiab ua haujlwm ntev yog qhov tseem ceeb, xws li lub tsheb fais fab, lub tshuab hluav taws xob tauj dua tshiab, thiab qee cov khoom siv hluav taws xob. LiFePO4 roj teeb tsis tshua muaj cua sov thiab thermal runaway piv rau lwm yam lithium-ion roj teeb chemistry, ua rau lawv nyiam xaiv hauv cov xwm txheej uas kev nyab xeeb yog qhov kev txhawj xeeb tshaj plaws.
Txawm li cas los xij, muaj lwm yam lithium-ion roj teeb chemistry, xws li lithium cobalt oxide (LiCoO2), lithium manganese oxide (LiMn2O4), thiab lithium nickel cobalt manganese oxide (LiNiCoMnO2 lossis NMC). Cov tshuaj sib txawv no muaj qhov sib txawv ntawm qhov sib txawv ntawm lub zog ceev, lub neej voj voog, kev nyab xeeb, thiab nqi.
Yog li, txhawm rau txheeb xyuas, thaum LiFePO4 yog hom roj teeb lithium-ion, nws tsis yog lub ntsiab lus nrog "lithium roj teeb," vim muaj ntau hom lithium-ion roj teeb chemistry nrog cov yam ntxwv sib txawv thiab kev siv.
