Taw qhia:
Cov roj teeb yog qhov tseem ceeb ntawm ntau lub tshuab thiab cov tshuab, los ntawm smartphones thiab lub laptop rau cov tsheb thiab hnub ci cia. Paub txog hom roj teeb uas koj siv yog qhov tseem ceeb rau kev nyab xeeb, txij nkawm thiab muab pov tseg. Ob hom roj teeb uas muajlithium-ion (Li-ion)thiab coj-kua roj teeb. Txhua hom muaj nws tus yam ntxwv thiab xav tau kev sib tw sib txawv. Hauv tsab xov xwm no, peb yuav sib tham yuav qhia li cas yog tias lub roj teeb yog lithium lossis txhuas, thiab qhov sib txawv ntawm ob.
Kev tshwm sim
Ib txoj hauv kev yooj yim tshaj plaws los sib txawv ntawm cov roj teeb lithium thiab cov hmoov txhuas yog los ntawm lawv lub cev. Coj-kua roj teeb feem ntau loj dua thiab hnyav dualithium-ion roj teeb.Lawv feem ntau yog cov duab plaub lossis xwmfab ua cov duab thiab muaj qhov sib cav sib txawv ntawm lub hau ntawm sab saum toj rau cov dej ntxiv. Hauv kev sib piv, Lithium-ion roj teeb feem ntau me dua, sib dua, thiab tuaj nyob rau ntau yam duab, suav nrog cylindrical thiab prismatic. Lawv tsis muaj lub tshuab npog thiab feem ntau yog ntim rau hauv ib lub hnab yas.
Cim npe thiab cim npe
Lwm txoj hauv kev los txheeb xyuas lub roj teeb yog los xyuas cov ntawv cim thiab cov cim ntawm lub roj teeb nws tus kheej. Lead-acid roj teeb feem ntau muaj cov ntawv me xws li qhov no, thiab lawv kuj yuav muaj cov cim qhia txog qhov hluav taws xob voltage thiab muaj peev xwm. Tsis tas li ntawd, coj-kua roj teeb feem ntau tau ceeb toom cov ntawv qhia txog kev phom sij ntawm cov sulfuric acid thiab qhov xav tau kom yog qhov cua. Lithium-ion roj teeb, ntawm qhov tod tes, feem ntau yog sau npe nrog cov ntaub ntawv hais txog tshuaj lom neeg, voltage, muaj zog muaj zog. Lawv kuj tseem muaj cov cim qhia ua raws li cov qauv kev nyab xeeb, xws li UL (Underwriters Chaw soj ntsuam) lossis CE (Europe Kev Ntsuam Xyuas Kev Ntsuas Xyuas).
Voltage thiab muaj peev xwm
Lub roj teeb lub voltage thiab peev xwm tseem tuaj yeem muab cov lus qhia txog nws hom. Lead-acid roj teeb feem ntau muaj nyob rau hauv voltages ntawm 2, 6, lossis 12 lub volts thiab feem ntau siv nyob rau hauv cov zis tam sim no, xws li lub tsheb pib roj teeb. Cov roj teeb lithium-ion, ntawm qhov tod tes, muaj lub zog loj dua los ntawm 3.7 volts rau ib lub xovtooj loj siv hauv cov tsheb hluav taws xob loj siv hauv cov hluav taws xob lossis lub zog cia lub tshuab.
Kev saib xyuas
Nkag siab txog kev saib xyuas roj teeb kom tau los kuj tseem tuaj yeem txheeb xyuas nws hom. Lead-kua roj teeb yuav tsum tau tu cov dej tsis tu ncua, tu kom tsis txhob muaj qhov cua nyob tiv thaiv kev ua kom tiv thaiv kom tsis txhob muaj kev tsim cov roj carrogen. Hauv kev sib piv,lithium-ion roj teebyog tu-dawb thiab tsis tas yuav ywg dej ib txwm los yog kev tu lub davhlau ya nyob twg. Txawm li cas los xij, lawv yuav tsum tau tiv thaiv tawm tsam overcharging thiab sib sib zog nqus kom tiv thaiv kev puas tsuaj thiab xyuas kom meej.
Cuam tshuam rau ib puag ncig
Qhov cuam tshuam ib puag ncig ntawm lub roj teeb tuaj yeem yog qhov kev txiav txim siab tseem ceeb thaum txiav txim siab hom roj teeb. Lead-acid roj teeb muaj cov hmoov txhuas thiab sulfuric acid, ob ntawm uas tuaj yeem tsim kev phom sij rau ib puag ncig yog tias tsis tswj kom zoo. Hmoov txhuas yog tshuaj lom neeg hnyav thiab sulfuric acid yog corrosive thiab tuaj yeem ua rau cov av thiab dej paug tsis tau thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo thiab pov tseg kom zoo thiab pov tseg thiab pov tseg kom zoo. Cov roj teeb lithium-ion kuj tseem muaj cov kev sib tw ib puag ncig vim muaj cov roj ntsha, uas tseem tuaj yeem ua rau thermal khiav tawm kom yog. Nkag siab txog cov kev cuam tshuam ib puag ncig ntawm cov roj teeb tuaj yeem pab koj ua kev txiav txim siab txog kev txiav txim siab txog roj teeb thiab pov tseg.
Pov tseg thiab rov ua dua tshiab
Cov khoom pov tseg kom raug thiab rov qab siv roj teeb yog qhov tseem ceeb rau kev cuam tshuam ib puag ncig thiab kho cov khoom muaj txiaj ntsig ib puag ncig. Lead-kua roj teeb feem ntau siv tau rov qab coj mus rov qab cov hmoov txhuas thiab yas, uas tuaj yeem siv los ua cov roj teeb thiab lwm cov khoom lag luam tshiab. Siv cov roj teeb-acid-acidies pab tiv thaiv cov tshuaj txhuas thiab tshuaj xyuas cov khoom ntuj.Lithium-ion roj teebKuj tseem muaj cov khoom muaj txiaj ntsig xws li Lithium, cobalt thiab npib tsib xee, uas tuaj yeem rov ua dua tshiab thiab siv roj teeb tshiab. Txawm li cas los xij, cov roj teeb rov ua dua rau cov roj teeb lithium-ion tseem tab tom tsim kho, thiab cov txheej txheem ua kom zoo dua yog qhov tseem ceeb rau kev ua kom muaj kev phom sij ib puag ncig.
Xav Txog Kev Ruaj Ntseg
Kev nyab xeeb yog qhov tseem ceeb ntawm kev tuav roj teeb, tshwj xeeb yog cov roj teeb lithium-huav, uas yog cov roj teeb uas tsis raug mob. Nkag siab txog kev nyab xeeb ceev faj rau txhua hom roj teeb yog qhov tseem ceeb rau kev tiv thaiv kev sib raug zoo thiab ua kom muaj kev tuav kom zoo. Lead-kua roj teeb tuaj yeem tso tawm hydrogen gas yog tias overcharged lossis luv-ciroge, thiab tuaj yeem ua rau muaj tshuaj hlawv yog tias cov electrolyte nkag mus rau daim tawv nqaij lossis lub qhov muag. Kev ceev faj kev nyab xeeb kev nyab xeeb, xws li siv cov khoom tiv thaiv tus kheej thiab cov qauv tsim qauv hauv qab no, yog qhov tseem ceeb thaum ua haujlwm nrog ib hom roj teeb.
Tag
Hauv cov ntsiab lus, txheeb xyuas seb lub roj teeb yog lithaium lossis cov khoom siv sia, suav nrog cov khoom siv ntawm lub cev, cov khoom siv hluav taws xob, cov kev xaiv pov tseg thiab cov kev txiav txim siab ntawm kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb, thiab kev saib xyuas kev nyab xeeb. Los ntawm kev nkag siab txog qhov sib txawv ntawm cov roj teeb lithium-ion thiab cov koomhaum thiab cov khoom siv acid tuaj yeem hais txog kev txiav txim siab txog lawv siv, txij nkawm, thiab pov tseg. Kev qhia kom paub tseeb thiab tuav cov roj teeb yog qhov tseem ceeb rau kev nyab xeeb, kev tiv thaiv ib puag ncig thiab kev txuag. Yog tias tsis paub txog cov hom roj teeb, nws raug pom zoo los sab laj rau cov chaw tsim tshuaj paus lossis tus kws tshaj lij kev coj ua.
