YUAV UA LI CAS LEAD-ACID Batteries tseem nyob hauv kev siv hnub ci
Oct 24, 2022
Kev sib tw thoob ntiaj teb los tsim cov roj teeb txaus rau lub zog cia tsuas yog pib tuaj tos. Txawm hais tias ntau lub tuam txhab roj teeb tau nqis peev hauv kev tshawb fawb, kev tsim kho thiab tsim cov lithium chemistry, ob qho tib si tshiab thiab ntau cov tuam txhab tsim nrog keeb kwm ntev ntawm cov roj teeb kua qaub kuj tseem ua rau kev lag luam nce qib ntawm cov khoom siv thiab tsim kom tau raws li qhov xav tau.
Qhov txiaj ntsig loj tshaj plaws ntawm cov kua qaub cia yog tias nws tuaj yeem ntsia tau ntawm tus nqi qis dua - qee tus hais tias 40 mus rau 50 feem pua - dua li lithium-based system. Tus nqi qis dua txhais tau hais tias ntau lub tsev nyob thiab kev lag luam lub zog cia yuav tawm, uas ua rau cov nqi saws me nyuam sai.
Txawm li cas los xij, tus nqi qis no feem ntau yog offset los ntawm kev xav tau kev saib xyuas ntau dua thiab lub neej voj voog luv. Ob lossis ntau dua cov roj ntsha lead-acid yuav tsum tau nyob rau hauv qhov chaw ntawm txhua lub roj teeb lithium hauv cov tsev khaws khoom lossis kev lag luam. Tsuas yog lub sijhawm, nrog rau ob peb xyoos ntawm cov ntaub ntawv ua tau zoo lithium, yuav qhia peb tias lub neej tiag tiag ntawm cov hlau lead rau lithium yuav yog li cas.
Cov xov xwm zoo rau cov kua qaub chemistry yog qhov kev nce qib tshiab hauv kev tsim lub npe hu ua carbon- lead acid roj teeb, uas txo cov kua qaub uas xav tau thiab qhov zaus ntawm kev saib xyuas, nrog rau lub neej ntawm lub voj voog.
Nyob rau hauv tib txoj hlab ntsha, Firstek Battery's premium Series 5000 cov roj teeb uas muaj cov hmoov lead-acid, uas yog tsim los siv hauv tsev los khaws cov hwj chim loj, muaj lub zog, hnyav phaj qauv, ib qho tshwj xeeb dual-tank vaj tse tsim , thiab muaj peev xwm ntau dua 7, 000 cycles ntawm 20 feem pua tawm qhov tob thiab 5,000 lub voj voog ze li 50 feem pua tawm.
"Qhov sib ntxiv ntawm firstek' tshwj xeeb Advanced NAM nano carbon additive rau cov phaj tsis zoo ntawm cov qauv dej nyab lead-acid txhim kho tag nrho cov nqi txais thiab txo tus nqi kub, muab kev nce nqi ntawm cov nqi ntawm 10-15 feem pua, yuav tsum tau luv dua. tsub nqi sijhawm, thiab kev txhim kho hauv Ib Feem Ntawm Lub Xeev Ntawm Tus Nqi (PSOC) kev ua haujlwm, "
Cov txiaj ntsig ntawm kev nyab xeeb thiab qhov hnyav
Tsis tas li ntawd, kev nyab xeeb tau raug txhim kho nrog cov qauv siv lead ua kua qaub tshiab, uas zam kev pheej hmoo ntawm hluav taws kub lithium roj teeb. "Silicon bi-pole roj teeb xav tau tsawg dua roj teeb tswj hluav taws xob hluav taws xob thiab hluav taws xob tiv thaiv tawb. Nws txuag tus nqi thiab qhov nyuaj thaum koj xav tau cov khoom siv hluav taws xob tsawg dua los taug qab thiab qhia txog qhov kub thiab txias ntawm lub roj teeb,
Qhov hnyav ntawm cov roj teeb kua qaub tshiab kuj tseem poob qis, uas yog pab rau cov neeg ua haujlwm txhim kho, uas tej zaum yuav nyiam lub roj teeb me me rau ib qho me me.
"Peb cov roj teeb Silicon Joule yog 40 feem pua sib dua vim tias lawv hloov cov kab hluav taws xob hnyav nrog cov tshuaj silicon wafers tshwj xeeb."
Recycling txo tus nqi ntawm kev hloov pauv
Nrog rau qhov kev nce qib no, cov roj carbon txhuas tuaj yeem siv tau ntau dua 99 feem pua ntawm kev lag luam, tsis zoo li cov roj teeb lithium, uas tseem nyob rau theem pib (thiab cov neeg txiav txim siab tseem tsis tau paub meej tias lawv yuav ua li cas). Feem ntau, lub zog cia yog cov tshuaj ntsuab piv rau cov fossil fuels, tab sis kev tswj cov ntaub ntawv yog ib feem tseem ceeb ntawm tag nrho cov duab.
"Nyob rau hauv 2018, ntiaj teb no Pb thiab Li-ion muag tau sib npaug ntawm $ 35 nphom txhua xyoo, tab sis Pb muag tau 4x ntau dua ntawm GWh, yog li xyoo 2018 Pb yog 4x tsawg dua ntawm $ / KWh. Tam sim no hauv 2020 lub ntiaj teb Pb. Lub lag luam roj teeb muaj nqis txog $ 37.5 nphom, nrog 410 GWh tsim. Lub ntiaj teb Li-ion kev ua lag luam muaj nqis txog $ 47.5 nphom nrog 230 GWh. Qhov ntawd txhais ua tus nqi nruab nrab ntawm $ 91 ib kWh rau Pb thiab $ 206 ib kWh rau Li-ion, yog li ntawd qhov txawv yog tam sim no tsuas yog 2.3 npaug. "
Tshwj xeeb tshaj yog, txoj kev tshawb fawb qhia tias "cov roj teeb uas siv lead ua yuav txuas ntxiv ua tus thawj coj hauv 2030" rau lub zog tsis cuam tshuam (UPS) thiab kev siv xov tooj. Txawm li cas los xij, "rau lub zog khaws cia, los ntawm 2030, cov tshuab nyiam yuav luag tag nrho lithium-based." Kev sib tw yog nyob rau.
