Qhov sib txawv tseem ceeb ntawm cov roj ntsha roj ntsha thiab cov roj alkaline yog cov roj teeb uas muaj kua qaub tuaj yeem rov qab tau thaum cov roj teeb alkaline feem ntau tsis rov them dua.
Ib lub roj teeb yog ib qho khoom siv uas muaj ib lossis ntau lub hlwb electrochemical. Nws muaj kev sib txuas sab nraud uas peb tuaj yeem txuas rau cov khoom siv hluav taws xob xws li smartphones, teeb nyem, thiab lwm yam. Ntxiv mus, nws muaj lub davhlau ya nyob twg zoo / cathode thiab lub davhlau ya nyob twg anode tsis zoo. Lead acid roj teeb thiab alkaline roj teeb yog ob lub roj teeb uas tuaj yeem muab cov khoom siv hluav taws xob xav tau.
Lead Acid Battery yog dab tsi?
Lub roj teeb ua kua qaub yog ib lub roj teeb uas siv tau thaum ntxov thiab tseem siv dav. Nws muaj zog tsawg heev rau qhov hnyav piv. Ntxiv mus, nws muaj tsawg zog rau ntim piv. Tsis tas li ntawd, lub roj teeb no muaj peev xwm muab cov khoom siv hluav taws xob siab; Yog li, nws muaj lub zog loj rau qhov hnyav piv. Cov roj teeb no yog cov khoom siv qis.
Nyob rau hauv lub xeev them tag nrho ntawm lub roj teeb, nws cov phaj tsis zoo yog txhuas, thiab cov phaj zoo yog txhuas oxide. Ntawm no, peb siv cov concentrated sulfuric acid ua cov electrolyte. Cov electrolyte khaws feem ntau ntawm cov tshuaj muaj zog. Txawm li cas los xij, thaum them nyiaj, overcharging yuav ua rau tsim cov pa oxygen thiab hydrogen gases vim electrolysis ntawm dej. Nws yog kev poob rau lub cell.
Thaum lub sijhawm tso tawm ntawm lub roj teeb, hydrogen ions tsim ntawm lub phaj tsis zoo, thiab cov ions no txav mus rau cov tshuaj electrolyte thiab tau noj ntawm lub phaj zoo. HSO4– ion noj tshwm sim ntawm ob daim hlau. Thaum lub sijhawm them nyiaj, qhov rov qab ntawm cov kev cuam tshuam no tshwm sim.
Nyob rau hauv lub xeev tawm ntawm lub roj teeb, ob qho tib si zoo thiab tsis zoo daim hlau ua lead (II) sulfate. Cov electrolyte poob feem ntau ntawm nws cov sulfuric acid yaj thiab ua dej. Daim duab qhia txog lub xeev tso tawm tag nrho ntawm cov roj teeb lead acid yog raws li hauv qab no:
Daim duab 02: Tawm Xeev
Alkaline roj teeb yog dab tsi?
Lub roj teeb alkaline yog hom roj teeb thawj, thiab nws lub zog yog tsim los ntawm cov tshuaj tiv thaiv ntawm zinc hlau thiab manganese oxide. Lub npe alkaline roj teeb pib los ntawm nws cov alkaline electrolyte: potassium hydroxide. Ib txhia ntawm cov roj teeb no yog rechargeable, tab sis qhov kev sim rau recharge lub roj teeb feem ntau rupture nws.
Daim duab 03: Rupted Alkaline Battery
Hauv lub roj teeb no, cov electrode tsis zoo yog zinc hlau, thiab cov electrode zoo yog manganese oxide (MnO 2). Txawm li cas los xij, alkaline electrolyte tsis koom nrog cov tshuaj tiv thaiv. Nws tseem tsis tau hloov pauv vim tias qhov sib npaug ntawm cov hydroxide ions tau noj thiab tsim thaum lub sijhawm tso tawm. Ntawm no, lub zog tshuaj yog khaws cia rau hauv cov hlau zinc.
Qhov txawv ntawm Lead Acid Battery thiab Alkaline Roj teeb yog dab tsi?
Lub roj teeb ua kua qaub yog ib qho ntawm cov roj teeb uas siv tau thaum ntxov tseem siv dav. Lub caij no, lub roj teeb alkaline yog hom roj teeb tseem ceeb, thiab nws lub zog yog tsim los ntawm cov tshuaj tiv thaiv ntawm zinc hlau thiab manganese oxide. Qhov sib txawv tseem ceeb ntawm cov roj teeb lead acid thiab alkaline roj teeb yog tias cov roj teeb lead acid yog rechargeable thaum cov roj teeb alkaline feem ntau tsis tuaj yeem them rov qab.
Ntxiv mus, feem ntau ntawm cov tshuaj zog ntawm lub roj teeb yog khaws cia rau hauv cov electrolyte nyob rau hauv cov hlau lead acid, tab sis nyob rau hauv alkaline roj teeb, lub zog yog khaws cia nyob rau hauv zinc hlau. Qhov sib txawv ntxiv ntawm cov roj teeb lead acid thiab alkaline roj teeb yog tias cov roj teeb lead acid siv cov electrolyte thaum tawm, tab sis lub roj teeb alkaline tsis.
Summary – Lead Acid Battery vs Alkaline Battery
Lub roj teeb ua kua qaub yog ib qho ntawm cov roj teeb uas siv tau thaum ntxov tseem siv dav. Tab sis, lub roj teeb alkaline yog hom roj teeb tseem ceeb, thiab nws lub zog tsim los ntawm cov tshuaj tiv thaiv ntawm zinc hlau thiab manganese oxide. Qhov sib txawv tseem ceeb ntawm cov roj teeb lead acid thiab alkaline roj teeb yog tias cov roj teeb lead acid yog rechargeable thaum cov roj teeb alkaline feem ntau tsis tuaj yeem them rov qab.
