1. Nyhav zog ceev:
Tam sim no, lub zog ceev ntawm lithium-ion roj teeb feem ntau nyob nruab nrab ntawm 200-260wh/g, thiab lead-acid feem ntau yog nyob nruab nrab ntawm 50-70wh/g. Yog li ntawd, lub zog hnyav ntawm lithium-ion roj teeb yog 3-5 npaug ntawm cov roj ntsha lead-acid. Qhov no txhais tau hais tias nyob rau hauv tib lub peev xwm, txhuas-acid roj teeb yog 3-5 npaug ntawm lithium-ion roj teeb. Yog li ntawd, nyob rau hauv cov nqe lus ntawm lub teeb yuag lub zog cia li, lithium-ion roj teeb muaj qhov zoo tshaj plaws.
2. Volume zog ceev:
Lub ntim muaj peev xwm ceev ntawm lithium-ion roj teeb feem ntau yog kwv yees li 1.5 npaug ntawm cov roj ntsha lead-acid, yog li nyob rau hauv tib lub peev xwm, lithium-ion roj teeb muaj li 30% me dua li cov roj teeb ntim.
3. Kev siv lub voj voog:
Cov khoom siv nrov tam sim no yog ternary thiab hlau lithium. Lub voj voog lub sij hawm ntawm ternary fais fab lithium-ion roj teeb feem ntau yog ntau tshaj 1000 zaug, thaum lub sij hawm lub voj voog ntawm hlau phosphate lithium-ion roj teeb muaj ntau tshaj 2000 zaug. Lub sij hawm lub voj voog ntawm cov roj teeb feem ntau tsuas yog kwv yees li 300-350 zaug, yog li lub neej kev pab cuam ntawm cov roj teeb lithium-ion yog li ntawm 3-6 npaug ntawm cov roj ntsha lead-acid.
4. Nqe:
Tam sim no, cov roj teeb lithium-ion yog kwv yees li peb zaug kim dua li cov roj ntsha lead-acid ntawm tus nqi. Txawm li cas los xij, raws li kev txheeb xyuas ntawm lawv lub neej kev pab cuam, yog tias tus nqi qub tau nqis peev, lub neej kev pab cuam ntawm lithium-ion roj teeb tseem ntev dua.
5. Kev siv tau:
Cov roj teeb lithium ion muaj kev nyab xeeb me ntsis piv rau cov roj ntsha lead-acid, yog li yuav tsum tau ua ntau yam kev tiv thaiv kev nyab xeeb thaum siv, xws li tiv thaiv sab nraud los yog kev sib tsoo los ntawm kev puas tsuaj rau lithium-ion roj teeb, vim qhov no yuav ua rau hluav taws kub lossis tawg; Tam sim no, qhov ntsuas kub ntawm cov roj teeb lithium-ion kuj zoo heev, yog li hauv lwm yam kev hloov pauv, cov roj teeb lithium-ion tsis tsawg dua li cov roj ntsha lead-acid.
6. Kev siv:
Cov roj teeb lead acid: siv rau lub tsheb pib, lub tsheb fais fab, roj teeb lithium-ion: siv rau cov xov tooj ntawm tes, khoos phis tawj, cov cuab yeej hluav taws xob, UPS cov khoom siv hluav taws xob, thiab lwm yam, thiab tam sim no kuj siv rau cov roj teeb tsheb hluav taws xob.
7. Cov khoom siv sab hauv:
Cov electrodes zoo thiab tsis zoo ntawm cov roj ntsha lead-acid yog cov hlau lead oxide, hlau lead, thiab cov electrolyte yog concentrated sulfuric acid. Qhov zoo thiab tsis zoo electrodes ntawm lithium-ion roj teeb yog lithium cobalt oxide / lithium hlau phosphate / lithium manganese oxide, graphite, thiab organic electrolytes.
8. Kev ruaj ntseg:
Kev nyab xeeb ntawm lithium-ion roj teeb los ntawm kev ruaj ntseg thiab txhim khu kev qha kev nyab xeeb tsim ntawm cov khoom siv electrode zoo. Lithium hlau phosphate kiag li daws cov teeb meem kev nyab xeeb ntawm lithium cobalt oxide thiab lithium manganese oxide. Cov roj ntsha lead acid tuaj yeem tawg nyob rau hauv kev sib tsoo muaj zog, thaum lithium hlau phosphate tau dhau los kuaj kev nyab xeeb thiab yuav tsis tawg txawm tias muaj kev sib tsoo hnyav.
9. Kev tiv thaiv ib puag ncig:
Cov roj teeb lithium hlau phosphate tsis muaj cov hlau hnyav lossis cov hlau tsis tshua muaj, tsis muaj tshuaj lom, thiab tsis muaj kuab paug hauv kev tsim khoom thiab siv. Lawv ua raws li European RoHS cov cai thiab yog cov roj teeb zoo ib puag ncig. Txawm li cas los xij, cov roj ntsha lead-acid muaj cov hmoov txhuas ntau, uas, yog tias tsis muab pov tseg kom zoo tom qab muab pov tseg, tseem tuaj yeem ua rau muaj kev puas tsuaj rau ib puag ncig.
10. Ua haujlwm kub ntau:
Qhov ntsuas kub ua haujlwm ntawm lithium-ion roj teeb yog -20-60 degree . Tsis txhob siv cov cua txias kom txo cov khoom siv, kev kho, thiab hluav taws xob. Qhov ntsuas kub ua haujlwm ntawm cov roj ntsha lead-acid yog 15-35 degree .
