Cov roj teeb lithium ion thiab cov roj ntsha lead-acid yog ob hom roj teeb uas muaj qhov sib txawv ntawm cov qauv, kev ua haujlwm, thiab kev siv. Cov hauv qab no yog ib qho kev ntsuam xyuas ntawm lawv qhov sib txawv thiab qhov zoo sib xws:
1. Cov qauv thiab txoj haujlwm ua haujlwm:
Cov roj teeb lithium ion: Cov roj teeb lithium ion siv cov reciprocating migration ntawm lithium ions ntawm qhov zoo thiab tsis zoo electrodes kom ua tiav cov txheej txheem them thiab tawm. Nws cov electrode zoo feem ntau yog tsim los ntawm oxides (xws li lithium cobalt oxide, lithium manganese oxide, lithium hlau phosphate, thiab lwm yam), thiab nws cov electrode tsis zoo yog ua los ntawm cov ntaub ntawv carbon (xws li graphite). Electrolytes feem ntau yog kua electrolytes uas muaj cov organic solvents thiab lithium ntsev.
Lead acid roj teeb: Lead acid roj teeb yog cov cuab yeej paub tab, qhov zoo electrode yog lead dioxide (PbO2) thiab cov electrode tsis zoo yog cov hmoov lead dawb (Pb). Cov electrolyte yog dilute sulfuric acid tov. Thaum them nyiaj, cov tshuaj sulfuric acid hauv cov electrolyte yog electrolyzed rau hauv oxygen thiab dej, thaum tsim cov hlau lead dioxide ntawm qhov zoo electrode thiab cov hmoov lead ntshiab ntawm cov electrode tsis zoo.
2. Zog ceev:
Cov roj ntsha lithium ion feem ntau muaj lub zog hluav taws xob ntau dua, lub ntsiab lus lawv khaws ntau lub zog rau ib chav phaus lossis ntim. Qhov no tso cai rau cov roj teeb lithium-ion khaws ntau lub zog hauv tib lub ntim lossis qhov hnyav, ua rau lawv tsim nyog rau cov ntawv thov uas xav tau lub zog loj, xws li xov tooj ntawm tes, laptops, thiab tsheb fais fab.
Lead acid roj teeb muaj lub zog qis dua, yog li lawv khaws cia tsawg zog hauv tib lub ntim lossis qhov hnyav. Lawv feem ntau siv rau hauv cov ntawv siv hluav taws xob tsawg thiab lub neej ntev, xws li tsheb pib roj teeb, UPS systems, thiab hnub ci zog cia.
3. Kev them nyiaj yug thiab tso tawm kev ua haujlwm:
Cov roj teeb lithium ion muaj kev them nqi zoo dua thiab kev ua haujlwm tawm, uas tuaj yeem ua tiav kev them nqi nrawm dua thiab ntau dua tus nqi tawm. Qhov no muab cov roj teeb lithium-ion kom zoo dua hauv cov ntawv thov uas yuav tsum tau them sai sai thiab cov khoom siv hluav taws xob siab, xws li tsheb hluav taws xob thiab cov khoom siv hluav taws xob portable.
Kev them nyiaj thiab tso tawm kev ua haujlwm ntawm cov roj ntsha lead-acid yog qhov tsawg, nrog kev them nqi qeeb thiab qis qis. Lawv tsim nyog rau cov ntawv thov uas xav tau cov khoom siv ruaj khov thiab siv tau ntev, xws li cov khoom siv hluav taws xob thaub qab thiab lub zog cia ntev.
4. Lub neej thiab ib puag ncig cuam tshuam:
Cov roj teeb lithium ion feem ntau muaj lub neej voj voog ntev dua thiab qis dua tus kheej tawm tus nqi, thiab tsis muaj cov khoom tsis zoo xws li cov hlau hnyav hnyav, yog li lawv qhov cuam tshuam rau ib puag ncig me me.
Lead acid roj teeb muaj lub neej luv luv thiab muaj cov hlau lead hnyav, uas ua rau muaj kuab paug ib puag ncig. Yog li ntawd, yuav tsum tau saib xyuas ntau dua rau kev rov ua dua thiab ua tiav.
Hauv cov ntsiab lus, cov roj ntsha lithium-ion muaj qhov tseem ceeb hauv lub zog ntom, ua kom haum rau kev siv uas xav tau lub zog ua kom zoo thiab ua haujlwm; Cov roj teeb uas siv lead ua kua qaub yog tsim rau cov ntawv thov nrog cov nqi qis dua, cov zis ruaj khov rau lub sijhawm ntev, thiab qis zog yuav tsum tau ua.
