Lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm Hnub Ci Zog Cia Roj Teeb: thaum them nyiaj, nws siv lub zog hluav taws xob sab nraud los tsim cov khoom siv sab hauv, khaws cov hluav taws xob ua hluav taws xob ua hluav taws xob, thiab hloov cov tshuaj siv hluav taws xob rau hauv hluav taws xob hluav taws xob rau cov zis thaum nws xav tau tawm, xws li lub xov tooj ntawm tes roj teeb uas nquag siv hauv lub neej.
Nws siv cov hlau lead substrate grid uas muaj spongy lead (tseem hu ua lub lattice) raws li ib tug tsis zoo electrode, ib tug lead substrate daim phiaj uas muaj lead dioxide raws li ib tug zoo electrode, thiab dilute sulfuric acid nrog ib tug ceev ntawm 1.26--1 .33g/mlg/ml yog siv los ua cov electrolyte. Thaum lub hnub ci zog cia roj teeb tawm, cov hlau lead yog qhov tsis zoo electrode, uas dhau los ua cov tshuaj tiv thaiv oxidation los tsim cov hlau lead sulfate; lead dioxide yog qhov zoo electrode, uas ua rau txo qis cov tshuaj tiv thaiv los tsim cov hlau lead sulfate. Thaum lub hnub ci zog cia roj teeb raug them nrog tam sim no ncaj qha, cov khoom siv lead ua thiab cov hmoov lead dioxide raug tsim ntawm ob tug ncej, feem. Thaum lub zog hluav taws xob raug tshem tawm, nws rov qab mus rau nws lub xeev ua ntej tso tawm, tsim cov tshuaj Solar Energy Storage Battery. Lub hnub ci zog cia roj teeb lead-acid tuaj yeem rov ua dua thiab tso tawm. Nws ib leeg-cell voltage yog 2v. Lub Hnub Ci Zog Cia Roj Teeb yog Lub Hnub Ci Lub Zog Cia Lub Roj Teeb muaj li ntawm ib lossis ntau lub hlwb, hu ua Solar Energy Storage Battery. Feem ntau yog cov roj teeb 6v thiab 12v. Lwm tus muaj xws li 2v, 4v, 8v, 24v Hnub Ci Zog Cia Roj Teeb. Piv txwv li, Hnub Ci Zog Cia Roj Teeb siv nyob rau hauv lub tsheb (feem ntau hu ua Solar Energy Storage Battery) yog lub hnub ci zog cia roj teeb ntawm 6 lub roj teeb txhuas-acid txuas nrog rau hauv series los tsim 12v Hnub Ci Zog Cia Roj Teeb.
Rau cov roj teeb uas siv roj ntsha qhuav (xws li lub tsheb qhuav-them roj teeb, lub roj teeb maus taus qhuav, thiab lwm yam), cov dej distilled yuav tsum tau ntxiv tom qab siv sij hawm kom cov dilute sulfuric acid electrolyte ntawm qhov ntom ntawm li 1.28g. /ml; nws yuav siv mus txog thaum kawg ntawm nws lub neej. Ntxiv cov dej distilled yog tsis tsim nyog.
Cov tshuaj tiv thaiv kab mob sib npaug yog raws li hauv qab no:
Zuag qhia tag nrho cov tshuaj tiv thaiv: pb(s) ntxiv rau pbo2(s) ntxiv rau 2 chi h2so4(aq) thim rov qab cim 2pbso4(s) ntxiv rau 2h2o(l)
Thaum tso tawm: tsis zoo pb(s)-2e- ntxiv rau42-(aq)=pbso4(s)
Positive pbo2(s) plus 2e- plus so42-(aq) plus 4h plus (aq)=pbso4(s) plus 2h2o(l)
Total pb(s) plus pbo2(s) plus 2h2so4(aq)=2pbso4(s) plus 2h2o(l)
Thaum them Electrolytic cell
Cathode pbso4(s) plus 2e-=pb(s) plus so42-(aq)
Anode pbso4(s) plus 2h2o(l)-2e-=pbo2(s) plus so42-(aq) plus 4h plus (a
