Hauv lub ntiaj teb uas hloov pauv sai sai ntawm kev khaws cia hluav taws xob, ob hom roj teeb tau ua xov xwm tseem ceeb:Cov roj teeb Sodium-ion (SIBs)thiabCov roj teeb Lithium-iron-phosphate (LFP roj teeb)Ob qho tib si thev naus laus zis roj teeb sodium thiab thev naus laus zis roj teeb lithium yog cov thev naus laus zis zoo, tab sis lawv muaj cov yam ntxwv sib txawv uas ua rau lawv haum rau ntau yam kev siv. Hauv tsab xov xwm no, peb yuav tshawb nrhiav seb cov roj teeb sodium-ion thiab lithium-iron-phosphate yog dab tsi, thiab tom qab ntawd piv lawv qhov sib txawv raws li cov kev tshawb pom tsis ntev los no.
Cov roj teeb Sodium-ion (SIBs) yog dab tsi?
Cov roj teeb Sodium-ion (SIBs)yog ib hom roj teeb uas siv tau dua uas siv sodium ions (Na+) ua cov khoom nqa. Sodium muaj ntau thiab pheej yig, ua rau SIBs yog ib lub roj teeb tshiab los hloov lithium.
Feem ntau SIBs siv cov pa roj carbon tawv ua cov khoom siv anode, uas txawv ntawm cov graphite feem ntau siv hauv LIBs. Cov ntaub ntawv cathode tuaj yeem sib txawv, tab sis lawv feem ntau tsim los kom haum rau qhov loj dua ntawm cov sodium ions piv rau lithium ions.
Cov roj teeb LFP (Lithium-iron-phosphate Battery) yog dab tsi?
Cov roj teeb Lithium-iron-phosphate (LFP roj teeb)yog ib hom roj teeb lithium-ion uas siv lithium hlau phosphate (LiFePO4) ua cov khoom siv cathode.
Cov roj teeb Lithium LiFePO4 paub txog lawv qhov kev ruaj khov thermal, lub neej ntev, thiab kev nyab xeeb.
Lawv siv dav hauv cov tsheb fais fab (EVs), kev khaws cia lub zog rov ua dua tshiab, thiab lwm yam kev siv uas kev nyab xeeb thiab lub neej ntev yog qhov tseem ceeb.
