"Puas yog lithium-ion roj teeb pob zoo dua lossis cov roj lead-acid zoo dua?" Qhov no yog ib lo lus nug uas ntau manufacturers engineers, buyers, thiab txawm tus thawj coj feem ntau tsom rau thaum tshawb fawb hom roj teeb siv nyob rau hauv lawv cov khoom. Tus editor yuav txheeb xyuas cov roj teeb lithium thiab cov roj teeb lead-acid los ntawm ntau qhov kev pom los pab koj txiav txim siab paub thaum xaiv hom roj teeb.
Ua ntej, cia peb txheeb xyuas lub zog ceev ntawm lub roj teeb ua ke. Lub zog ceev ceev txhais tau hais tias lub roj teeb tuaj yeem khaws hluav taws xob ntau dua hauv qhov hnyav tib yam. Lub zog ceev ntawm lithium roj teeb pob feem ntau yog nyob ib ncig ntawm 200-300Wh/kg. Thiab cov roj teeb lead-acid zoo tib yam tsuas muaj 40-70Wh/kg. Rau cov neeg tsim khoom uas xav tsim cov khoom siv hnyav thiab siv tau ntev, cov roj teeb lithium yuav yog qhov kev xaiv zoo dua.
Tom ntej no, cia peb txheeb xyuas lub neej kev pabcuam ua ke. Cov roj teeb txhuas txhuas feem ntau muaj lub sijhawm them thiab tawm lub voj voog lub neej ntawm tsuas yog 300-500 cycles, thaum cov roj teeb lithium feem ntau tuaj yeem ncav cuag 500-1000 cycles. Lub zog cia lithium hlau phosphate roj teeb pob tau ua tiav qhov kev xav tau ntawm lub neej tsawg kawg yog 2000 cycles. Rau cov tuam txhab uas xav tsim cov khoom lag luam nrog lub neej ntev thiab kev saib xyuas qis, nws raug nquahu kom xaiv cov roj teeb lithium.
Nyob rau hauv cov nqe lus ntawm kev ua raws li ib puag ncig thiab cov duab cov khoom, lithium roj teeb packs yog ib puag ncig tus phooj ywg ntau dua li cov roj teeb lead-acid, tsis zoo li cov uas muaj teeb meem hlau hnyav xws li txhuas (Pb) thiab cadmium (Cd) compounds. Rau cov tuam txhab lag luam uas tseem ceeb rau kev tiv thaiv ib puag ncig raws li lawv cov khoom muag muag thiab tsim lawv cov duab hom, xaiv cov lithium roj teeb pob yog qhov tsim nyog dua.
Nqe yog ib qho tseem ceeb uas txhua tus tsim khoom yuav tsum xav txog. Cov roj ntsha lead acid kuj tseem pheej yig dua, yog li cov roj teeb lithium-ion feem ntau maj mam siv los ntawm cov khoom lag luam siab mus rau nruab nrab mus rau cov khoom qis. Yog hais tias lub roj teeb nqi ntawm cov khoom yog heev txwv thiab positioned raws li tus nqi-zoo, lead-acid roj teeb tej zaum yuav yog ib qho kev xaiv ntau dua rau developers.
Thaum kawg, teeb meem kev ruaj ntseg kuj yog ib yam uas cov neeg tsim khoom yuav tsum tau saib xyuas. Lead acid roj teeb, tom qab ob peb xyoos ntawm txoj kev loj hlob, tam sim no kuj tseem ruaj khov thiab tsis tshua muaj tshwm sim los yog tawg. Txawm li cas los xij, vim nws lub zog siab ceev, cov lithium roj teeb yuav tsum muaj cov tuam txhab roj teeb lithium kom muaj lub zog ua haujlwm, sib xws kev nyab xeeb kev teeb tsa, thiab BMS cov tswv yim tswj kom tsis txhob overcharge, overheating, thiab lwm yam xwm txheej. Rau kev yuav khoom, engineers, lossis cov thawj coj, kom ntseeg tau tias kev nyab xeeb ntawm cov roj teeb pob yog qhov tseem ceeb, yog li thaum xaiv cov khoom siv roj teeb, lawv cov peev xwm yuav tsum tau ntsuas.
Hauv cov ntsiab lus, cov roj teeb lead-acid thiab lithium roj teeb pob txhua tus muaj lawv tus kheej qhov zoo thiab qhov tsis zoo. Yog li ntawd, cov lus nug ntawm seb cov roj teeb lithium puas zoo dua lossis tsis xav tau kev txiav txim siab los ntawm kev yuav khoom, engineers, lossis cov thawj coj los ntawm ntau qhov kev xav raws li qhov xav tau tiag tiag, suav nrog lub zog ntom ntom, kev pabcuam lub neej, kev tiv thaiv ib puag ncig, nqi, kev siv tau, thiab kev nyab xeeb. Nws raug nquahu kom ua qhov kev sib tham tob nrog cov kws tshaj lij thiab muaj zog lithium roj teeb manufacturers ntawm kev tsim khoom, nkag siab zoo txog cov xwm txheej no, thiab txiav txim siab kom raug los xyuas kom meej tias cov roj teeb uas tau xaiv tuaj yeem ua tau raws li cov khoom muag thiab ua tiav kev lag luam.
