Lithium-Ion roj teeb, raws li cov cuab yeej tseem ceeb rau kev khaws cia lub zog niaj hnub no, tuaj nyob rau hauv ntau hom, txhua tus muaj nws tus yam ntxwv hauv kev ua tau zoo, nqi, thiab kev siv cov xwm txheej.
Tam sim no, cov roj teeb tseem ceeb lithium-ion roj teeb hauv khw feem ntau suav nrog lithium- roj teeb ion (Li-}ion), lithium polymer roj teeb (Li-}Po), lithium hlau phosphate roj teeb (LiFePO4), thiab lithium titanate roj teeb (Lithium Oo 15Ti). Cov hauv qab no yog cov ncauj lus kom ntxaws txog cov lithium -Ion roj teeb hom.
Lithium-Ion roj teeb (Li-Ion) tam sim no yog hom lithium{2}}ion roj teeb uas siv dav tshaj plaws. Lawv cov ntaub ntawv zoo electrode feem ntau yog lithium cobalt oxide, lithium manganese oxide, los yog ternary cov ntaub ntawv (nickel-cobalt-manganese lithium oxide), thaum cov khoom tsis zoo electrode yog graphite. Lithium-ion roj teeb muaj qhov zoo xws li lub zog loj, lub neej ntev, thiab tus kheej qis- paug tus nqi, thiab tau dav siv hauv xov tooj ntawm tes, laptops, tsheb fais fab, thiab lwm yam. Tus nqi ntawm lithium{10}}ion roj teeb txawv nyob ntawm seb cov khoom siv electrode zoo.
Lithium polymer roj teeb (Li-Po) yog ib hom kev txhim kho ntawm lithium-ion roj teeb. Lawv cov electrolyte siv cov ntaub ntawv polymer, tso cai rau cov roj teeb tsim nyob rau hauv ntau yam duab thiab ntau thiab tsawg, muab kev tsim kom yooj yim dua. Cov roj teeb lithium polymer zoo ib yam li lithium- ion roj teeb nyob rau hauv cov nqe lus ntawm lub zog ceev, kev nyab xeeb, thiab lub voj voog lub neej, tab sis kim dua me ntsis. Vim lawv qhov nyias nyias thiab yoog raws, cov roj teeb lithium polymer feem ntau yog siv rau hauv cov khoom siv hnav, drones, thiab lwm yam kev siv uas lub roj teeb zoo yog qhov tseem ceeb.
Lithium hlau phosphate (LiFePO4) roj teeb paub txog lawv txoj kev nyab xeeb siab, lub neej ntev, thiab tus nqi qis. Lawv cov khoom zoo electrode yog lithium hlau phosphate, thiab lawv cov khoom tsis zoo electrode yog graphite. Cov roj teeb lithium hlau phosphate muaj qhov ruaj khov ntawm qhov kub thiab txias thiab tsis tshua muaj thermal runaway, ua rau lawv siv dav hauv tsheb fais fab, lub zog cia, thiab lwm yam.
Lithium titanate (Li4Ti5O12) roj teeb yog hom tshiab ntawm lithium roj teeb. Lawv cov khoom zoo electrode yog lithium titanate, thiab lawv cov khoom tsis zoo electrode yog graphite. Cov roj teeb lithium titanate muaj qhov zoo xws li lub neej voj voog ntev heev (txog kaum tawm txhiab lub voj voog), muaj peev xwm them tau sai, thiab kev nyab xeeb siab.
Dhau li ntawm cov lus hais saum toj no cov roj teeb lithium tseem ceeb, muaj lwm hom roj teeb lithium, xws li lithium{0}} roj teeb sulfur thiab lithium - roj teeb cua. Cov roj teeb no muaj peev xwm ua tau zoo hauv lub zog ceev thiab tus nqi, tab sis tam sim no tseem nyob rau hauv kev tshawb fawb thiab kev loj hlob theem thiab tseem tsis tau ua tiav loj - daim ntawv thov kev lag luam.
