LiFePo4 roj teeb hais txog lithium ion roj teeb nrog lithium hlau phosphate ua cov khoom zoo electrode thiab carbon raws li cov khoom tsis zoo electrode.
Ternary lithium roj teeb hais txog lithium roj teeb uas siv nickel-cobalt-manganate lithium los yog npib tsib xee-cobalt-aluminate lithium raws li cov khoom zoo electrode thiab graphite ua cov khoom tsis zoo electrode.Hom roj teeb no hu ua "ternary" vim hais tias cov nickel ntsev, cobalt ntsev thiab manganese ntsev raug kho hauv peb qhov sib txawv.
Shenzhen Meind Technology Co., Ltd tsis ntev los no tso tawm lub zog portableruaj khov khoom sivnrog built-in ternary lithium roj teeb, kuj hu uasab nraum zoov fais fab movlos yogportable fais fab chaw nres tsheb.Tab sis muaj ntaulub zog sab nraum zoovnyob rau hauv kev ua lag luam uas siv LiFePo4 roj teeb.Vim li cas peb thiaj siv ternary lithium roj teeb?Vim tias ternary lithium roj teeb kuj muaj qhov zoo (raws li hauv qab no) dhau LiFePo4 roj teeb.
1. Zog ceev
Feem ntau, ternary lithium roj teeb tuaj yeem khaws ntau lub zog rau ib chav tsev ntim lossis qhov hnyav, qhov no yog vim qhov sib txawv ntawm cov khoom siv electrode ntawm lawv.Cov khoom siv cathode ntawm LiFePo4 roj teeb yog lithium hlau phosphate, thiab ternary lithium roj teeb yog npib tsib xee cobalt manganese lossis npib tsib xee cobalt txhuas.Qhov sib txawv ntawm cov khoom siv tshuaj ua rau lub zog ntom ntom ntawm ternary lithium roj teeb ntawm tib lub zog 1.7 npaug ntawm LiFePo4 roj teeb.
2.Kev ua haujlwm kub qis
Kev ua tau zoo ntawm LiFePo4 roj teeb ntawm qhov kub thiab txias yog qhov phem dua li ntawm ternary lithium roj teeb.Thaum LiFePo4 nyob ntawm -10 ℃, lub peev xwm ntawm lub roj teeb poob mus txog 50%, thiab lub roj teeb tsis tuaj yeem ua haujlwm tshaj -20 ℃ feem ntau.Qhov qis qis ntawm ternary lithium yog -30 ℃, thiab lub peev xwm attenuation degree ntawm ternary lithium tsawg dua li ntawm LiFePo4 ntawm qhov kub thiab txias.
3. Kev them nyiaj ua haujlwm
Nyob rau hauv cov nqe lus ntawm kev them nqi efficiency, ternary lithium roj teeb yog ntau npaum.Cov ntaub ntawv sim qhia tau hais tias muaj qhov sib txawv me ntsis ntawm ob lub roj teeb thaum them qis dua 10 ℃, tab sis qhov kev ncua deb yuav raug kos thaum them tshaj 10 ℃.Thaum them nyiaj ntawm 20 ℃, qhov sib piv tam sim no ntawm ternary lithium roj teeb yog 52.75%, thiab ntawm LiFePo4 roj teeb yog 10.08%.Tus qub yog tsib zaug ntawm lub tom kawg.
