Taw qhia:
Lithium roj teebtau dhau los ua ib feem tseem ceeb ntawm peb lub neej niaj hnub, txhawb txhua yam ntawm smartphones thiab laptops mus rau lub tsheb hluav taws xob thiab cov khoom siv hluav taws xob tauj dua tshiab. Nyob rau hauv lub tshav pob ntawm lithium roj teeb, muaj ob yam tseem ceeb: low voltage (LV) roj teeb thiab high voltage (HV) roj teeb. Nkag siab txog qhov sib txawv ntawm ob hom roj teeb lithium no yog qhov tseem ceeb rau kev xaiv lub hwj chim zoo rau ib daim ntawv thov tshwj xeeb.
Tsawg voltage (LV) lithium roj teeb:
Tsawg-voltage lithium roj teeb feem ntau ua haujlwm ntawm qhov hluav taws xob qis dua 60V. Cov roj teeb no feem ntau yog siv rau hauv cov khoom siv hluav taws xob portable, cov cuab yeej hluav taws xob, thiab cov tshuab hluav taws xob me me. Cov roj teeb uas tsis muaj hluav taws xob paub txog lawv qhov loj me, tsim qauv hnyav thiab lub zog siab, ua rau lawv zoo tagnrho rau kev siv qhov chaw thiab qhov hnyav yog qhov tseem ceeb.
Tsawg-voltagelithium roj teebtseem paub txog lawv cov nqi qis dua piv rau cov roj teeb hluav taws xob siab. Qhov no ua rau lawv muaj kev xaiv nrov rau cov neeg siv khoom siv hluav taws xob thiab lwm yam kev siv hluav taws xob tsawg. Tsis tas li ntawd, cov roj teeb uas muaj hluav taws xob tsawg yooj yim dua rau kev tswj hwm thiab tswj xyuas vim qhov qis qis qis, uas tuaj yeem ua kom yooj yim rau kev tsim thiab siv cov roj teeb tswj cov tshuab.
High voltage (HV) lithium roj teeb:
High-voltagelithium roj teebmuaj kev khiav hauj lwm voltage siab tshaj 60V. Cov roj teeb no feem ntau yog siv rau hauv tsheb fais fab, daim phiaj hluav taws xob txuag hluav taws xob, thiab cov ntawv thov kev lag luam uas xav tau cov khoom siv hluav taws xob siab thiab lub zog muaj peev xwm. High-voltage roj teeb yog tsim los xa cov kev ua tau zoo thiab kev ua haujlwm zoo, ua rau lawv tsim nyog rau kev thov rau kev siv hluav taws xob siab.
Ib qho ntawm qhov sib txawv tseem ceeb ntawm cov roj teeb uas tsis muaj hluav taws xob thiab cov roj teeb siab yog lawv lub zog ceev. Cov roj teeb hluav taws xob siab feem ntau muaj lub zog ntau dua li cov roj teeb uas tsis muaj hluav taws xob, tso cai rau lawv khaws ntau lub zog hauv ib lub ntim lossis qhov hnyav. Lub zog siab ceev no yog qhov tseem ceeb rau kev siv xws li tsheb hluav taws xob, qhov twg kev tsav tsheb ntau tshaj plaws thiab lub zog tso tawm yog qhov tseem ceeb.
Lwm qhov sib txawv tseem ceeb yog qhov nyuaj ntawm kev tswj hwm roj teeb uas xav tau rau cov roj teeb hluav taws xob siab. Vim tias cov roj teeb hluav taws xob muaj hluav taws xob ntau dua thiab cov khoom siv hluav taws xob ntau dua, cov roj teeb uas muaj zog dua thiab muaj zog yuav tsum tau ua kom muaj kev nyab xeeb thiab ua haujlwm tau zoo. Qhov kev nyuaj no ua rau tus nqi tag nrho thiab cov teeb meem kev sib tw uas cuam tshuam nrog cov roj teeb hluav taws xob siab.
Kev xav txog kev nyab xeeb:
Rau lithium roj teeb, txawm tias tsawg lossis siab voltage, kev nyab xeeb yog qhov tseem ceeb. Txawm li cas los xij, cov roj teeb uas muaj hluav taws xob ntau ua rau muaj teeb meem kev nyab xeeb ntxiv vim lawv qhov hluav taws xob ntau dua thiab lub zog. Kev tuav kom zoo, cia, thiab kev saib xyuas cov roj teeb hluav taws xob siab yog qhov tseem ceeb rau kev tiv thaiv kev nyab xeeb kev nyab xeeb xws li thermal runaway, overcharging, thiab luv circuits.
Cov roj teeb uas tsis tshua muaj hluav taws xob, thaum feem ntau suav tias muaj kev nyab xeeb dua vim lawv qhov qis qis, tseem xav tau kev tuav thiab kev saib xyuas kom zoo kom txo tau qhov kev pheej hmoo ntawm thermal txheej xwm thiab lwm yam teeb meem kev nyab xeeb. Txawm hais tias qib voltage, nws yog ib qho tseem ceeb uas yuav tsum ua raws li cov chaw tsim khoom cov lus qhia thiab kev lag luam zoo tshaj plaws rau kev siv cov roj teeb lithium kom nyab xeeb.
Kev cuam tshuam rau ib puag ncig:
Ob leeg low-voltage thiab high-voltagelithium roj teebmuaj kev cuam tshuam rau ib puag ncig, tshwj xeeb tshaj yog nyob rau hauv lawv cov txheej txheem tsim khoom thiab qhov kawg ntawm lub neej pov tseg. Kev rho tawm thiab ua cov lithium thiab lwm yam khoom siv hauv kev tsim cov roj teeb tuaj yeem muaj kev cuam tshuam rau ib puag ncig, suav nrog cov peev txheej depletion thiab muaj kuab paug. Tsis tas li ntawd, kev rov ua dua tshiab thiab pov tseg cov roj teeb lithium yog qhov tseem ceeb kom txo qis lawv qhov chaw ib puag ncig.
Thaum muab piv rau cov roj teeb uas tsis muaj hluav taws xob thiab cov hluav taws xob siab, nws yog ib qho tseem ceeb uas yuav tau xav txog qhov cuam tshuam ib puag ncig ntawm lawv cov khoom, siv thiab pov tseg. Cov roj teeb uas muaj hluav taws xob siab tuaj yeem muaj kev cuam tshuam ntau dua rau ib puag ncig vim lawv qhov loj dua thiab muaj peev xwm muaj zog ntau dua li cov roj teeb hluav taws xob tsawg. Txawm li cas los xij, kev nce qib hauv kev siv roj teeb rov ua dua tshiab thiab kev tsim khoom lag luam txuas ntxiv los txhim kho ib puag ncig kev ua haujlwm ntawm lithium roj teeb.
Xaus:
Qhov sib txawv ntawm qhov tsawg-voltage thiab high-voltagelithium roj teebyog qhov tseem ceeb thiab yuav tsum tau ua tib zoo txiav txim siab thaum xaiv lub roj teeb rau ib daim ntawv thov tshwj xeeb. Cov roj teeb uas tsis muaj hluav taws xob yog qhov zoo tagnrho rau cov khoom siv hluav taws xob portable, cov cuab yeej hluav taws xob thiab cov khoom siv hluav taws xob me me, nrog rau lawv cov compact loj, lub teeb yuag thiab tus nqi qis. High-voltage batteries, ntawm qhov tod tes, yog tsim los rau kev siv hluav taws xob siab xws li tsheb fais fab thiab daim phiaj hluav taws xob cia, muab lub zog ntau dua thiab ua haujlwm tau zoo.
Txawm li cas los xij ntawm lithium roj teeb, kev nyab xeeb thiab ib puag ncig yuav tsum yog qhov tseem ceeb. Kev tuav, tu thiab pov tseg ntawm cov roj teeb lithium yog qhov tseem ceeb kom ntseeg tau tias lawv muaj kev nyab xeeb thiab siv tau. Raws li kev siv thev naus laus zis txuas ntxiv mus, tsim cov roj teeb lithium nrog kev txhim kho kev nyab xeeb, kev ua tau zoo thiab kev ruaj ntseg ib puag ncig yuav ua lub luag haujlwm tseem ceeb hauv kev tsim lub neej yav tom ntej ntawm kev khaws cia thiab hluav taws xob.
