Nyob rau hauv lub ntiaj teb hloov zuj zus sai ntawm lub zog cia, ob hom roj teeb tau ua cov ncauj lus tseem ceeb:Sodium-ion roj teeb (SIBs)thiabLithium-iron-phosphate roj teeb (LFP roj teeb). Ob qho tib si sodium roj teeb thev naus laus zis thiab lithium roj teeb thev naus laus zis tau cog lus thev naus laus zis, tab sis lawv muaj cov yam ntxwv sib txawv uas ua rau lawv tsim nyog rau kev siv sib txawv. Hauv tsab xov xwm no, peb yuav tshawb xyuas seb cov roj teeb sodium-ion thiab lithium-iron-phosphate yog dab tsi, thiab tom qab ntawd sib piv lawv qhov sib txawv raws li kev tshawb fawb tsis ntev los no.
Sodium-ion Batteries (SIBs) yog dab tsi?
Sodium-ion roj teeb (SIBs)yog ib hom roj teeb rechargeable uas siv sodium ions (Na+) raws li tus nqi thauj khoom. Sodium muaj ntau thiab pheej yig, ua rau SIBs lub roj teeb tshiab los hloov lithium.
SIBs feem ntau siv cov roj carbon nyuaj 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 ntawm sodium ions piv rau lithium ions.
LFP Roj teeb (Lithium-iron-phosphate Battery) yog dab tsi?
Lithium-iron-phosphate roj teeb (LFP roj teeb)yog ib qho subtype ntawm lithium-ion roj teeb cia uas siv lithium hlau phosphate (LiFePO4) ua cov khoom siv cathode.
Lithium LiFePO4 roj teeb paub txog lawv cov thermal stability, lub neej voj voog ntev, thiab kev nyab xeeb.
Lawv tau siv dav hauv tsheb hluav taws xob (EVs), lub zog txuas ntxiv mus, thiab lwm yam kev siv uas muaj kev nyab xeeb thiab kev ua neej ntev yog qhov tseem ceeb.
