Lead acid roj teeb

Lead-acid roj teeb

Covlead-acid roj teebyog ib hom roj teeb rechargeable thawj zaug tsim nyob rau hauv 1859 los ntawm Fabkis physicist Gaston Planté.Nws yog thawjzoontawm rechargeable roj teebtsim.Piv rau cov roj teeb uas siv tau niaj hnub no, cov roj ntsha lead-acid muaj lub zog tsis tshua muaj zog.Txawm li cas los xij, lawv lub peev xwm los muab cov hluav taws xob nce siab txhais tau hais tias cov hlwb muaj lub zog loj-rau-qhov hnyav.Cov yam ntxwv no, nrog rau lawv cov nqi qis, ua rau lawv txaus siab rau kev siv hauv tsheb tsav los muab cov kev xav tau siab tam sim no los ntawm cov pib motors.Cov roj teeb txhuas-acid raug kev txom nyem los ntawm lub voj voog luv luv (feem ntau tsawg dua 500 lub voj voog sib sib zog nqus) thiab tag nrho lub neej (vim "ob npaug ntawm sulfation" hauv lub xeev tawm).

Gel-hlwbthiababsorbed iav-matCov roj teeb muaj ntau hauv cov luag haujlwm no, suav nrog VRLA (valve-regulated lead-acid) roj teeb.

Nyob rau hauv lub xeev them, cov tshuaj lub zog ntawm lub roj teeb yog khaws cia nyob rau hauv lub peev xwm sib txawv ntawm cov hlau lead ntawm lub sab tsis zoo thiab PbO.₂ntawm qhov zoo.Nws muaj qhov zoo ntawm PbO2 thiab cov hlau tsis zoo hlau lead, rwb thaiv tsev board, rooj plaub yas, sulfuric acid thiab dej.

Thaum tso tawm, qhov zoo electrode cov tshuaj tiv thaiv:bO2 + 4H + SO42- + 2e- = PbSO4 + 2H2O

Cov tshuaj tiv thaiv tsis zoo: Pb + SO42- - 2e- = PbSO4

Zuag qhia tag nrho cov tshuaj tiv thaiv: PbO2 + Pb + 2H2SO4 === 2PbSO4 + 2H2O (Cov tshuaj tiv thaiv sab xis yog tawm, cov tshuaj tiv thaiv leaftward yog them).

Cov roj teeb uas siv lead ua kua qaub (WLABs) yog siv cov roj ntsha lead-acid uas yuav tsum tau muab pov tseg. 

Ntawm cov kev siv sib txawv ntawm WLABs, daim ntawv thov tseem ceeb tseem nyob hauv tsheb, thaum daim ntawv thov hauv UPS tsis cuam tshuam lub zog hluav taws xob yog ib qho kev tshwm sim vim kev loj hlob hauv kev sib txuas lus thiab cov ntaub ntawv Technology (tshwj xeeb yog cov chaw zov me nyuam).Nrog rau cov chaw khaws ntaub ntawv ntau ntxiv, nws cia siab tias WLABs tshwm sim los ntawm cov haujlwm no yuav nce ntxiv rau xyoo tom ntej.

Peb tuaj yeem muab ib qhoua kom tiav cov kua qaub roj teeb rov ua dua kab, nrog rau kev sib cais thiab kev sib cais, lub tshuab hluav taws xob, lub tshuab ua kom zoo, thiab cov roj lim dej, thiab lwm yam.

Xav paub ntau ntxiv, thov koj xav tiv tauj peb.
