Secondary (Rechargeable) Cov Khoom Siv Roj Teeb
Piv nrog rau lwm cov khoom siv roj teeb uas siv tau, cov roj teeb lithium-ion muaj qhov zoo ntawm cov hluav taws xob ntau dua, kev sib txuas yooj yim, thiab kev nyab xeeb dua thiab tawm nrog cov ntawv tiv thaiv.
Lawv tuaj yeem ua cov pob roj teeb uas muaj peev xwm sib txawv thiab qhov voltages. Lithium-ion roj teeb ntawm cov ntaub ntawv tshwj xeeb tuaj yeem ua tau raws li cov ntawv thov hauv ntau qhov chaw.
Piv txwv li, lithium ion roj teeb uas tsis kub thiab siab npaum li-ion roj teeb.
Kev ua haujlwm hluav taws xob ntawm polymer lithium roj teeb zoo ib yam li lithium ion roj teeb.
Nws yog lwm cov duab ntawm lithium ion roj teeb. Nws tuaj yeem ua rau cov duab sib txawv thiab ntau thiab tsawg ntawm cov txheej txheem tshwj xeeb thiab pwm kom tau raws li cov neeg siv khoom sib txawv.
Lithium cobalt oxide, ternary lithium, lithium manganate, lithium hlau phosphate, thiab lithium titanate tuaj yeem ua rau hauv cov roj teeb polymer lithium.
Lub nominal voltage ntawm lithium hlau phosphate roj teeb yog 3.2V, uas yog qis dua lithium ion roj teeb ntawm 3.7V, tab sis nws muaj lub neej voj voog ntev dua thiab muaj kev nyab xeeb dua.
Feem ntau siv nws txoj kev nyab xeeb thiab lub neej ntev, siv nyob rau hauv lub tshav pob ntawm lub zog cia thiab hluav taws xob tsheb.
Raws li cov khoom siv tshiab, LTO (lithium titanate roj teeb) muaj lub neej ntev dua thiab kev ua haujlwm kub ntau dua, tab sis lub platform voltage qis dua lwm cov roj teeb lithium rechargeable.
Cov roj teeb nickel hlau muaj qhov voltage ntawm 1.2V, suav nrog nim (nickel-hlau hydride), nicd (nickel-cadmium), thiab nizn (nickel-zinc) roj teeb.
Nws yog cov roj teeb rechargeable ua ntej pom cov roj teeb lithium.
Nws tuaj yeem siv ntau qhov sib txawv rau cov khoom siv kho mob, xov tooj ntawm tes, RC qauv thiab lwm yam kev lag luam feem ntau.
Vim yog lub koob npe nrov ntawm cov roj teeb lithium, cov chaw siv cov roj teeb nickel-hlau tau poob qis.
VRLA (Valve Regulated lead-acid) roj teeb (AGM / GEL) kev saib xyuas dawb tau ntsib lub sijhawm ntev heev hauv keeb kwm ntawm cov roj teeb rov qab.
Txawm hais tias lawv loj, hnyav, nrog cov hmoov txhuas, lawv muaj nqi tsawg. Nyob rau hauv ntau qhov chaw, kev txiav txim siab nqi tseem yuav xaiv cov roj teeb uas tsis muaj nqi txhuas-acid.
