Iibhetri ze-asidi yelothe

Ibhetri ye-lead-asidi

Iibhetri ye-lead-asidiluhlobo lwebhetri egcwalisekayo eyaqalwa ngo-1859 yingcali yefiziksi yaseFransi uGaston Planté.Yeyokuqalaububeleyebhetri egcwalisekayoyenziwe.Xa zithelekiswa neebhetri zale mihla eziphinda zitshajwe, iibhetri ze-lead-asidi zinokuxinwa kwamandla aphantsi.Ngaphandle koku, ukukwazi kwabo ukubonelela ngemisinga ephezulu kuthetha ukuba iiseli zinomlinganiselo omkhulu wobunzima bobunzima.Ezi mpawu, kunye neendleko zazo eziphantsi, zizenza zibe nomtsalane ukuba zisetyenziswe kwiimoto ukuze zibonelele ngokuphezulu kwangoku okufunwa ziinjini zokuqalisa.Iibhetri ze-lead-asidi zihlupheka kubomi bomjikelo omfutshane ngokwentelekiso (ngokuqhelekileyo ngaphantsi kwe-500 imijikelo enzulu) kunye nobude bobomi bubonke (ngenxa “yokusulfa kabini” kwimeko ekhutshiweyo).

Iiseli zeGelkwayeiglasi-mat efunxekileyoiibhetri ziqhelekile kwezi ndima, ngokudibeneyo zaziwa njengeebhetri ze-VRLA (i-valve-regulated lead-acid).

Kwimeko ehlawulweyo, amandla ekhemikhali ebhetri agcinwe kumahluko onokubakho phakathi kwentsimbi yentsimbi kwicala elibi kunye nePbO.₂kwicala elihle.Iqulethe icala elihle PbO2 kunye negtive metallic lead, ibhodi yokugquma, iplastiki yeplastiki, i-asidi yesulfuric kunye namanzi.

Xa ukhutshelwa, impendulo ye-electrode enhle:bO2 + 4H+ + SO42- + 2e- = PbSO4 + 2H2O

Ukusabela kakubi: Pb + SO42- - 2e- = PbSO4

Ukusabela xa iyonke: PbO2 + Pb + 2H2SO4 === 2PbSO4 + 2H2O (Impendulo yasekunene kukukhupha, ukusabela ngasekhohlo kuyatshaja).

Iibhetri ze-lead-asidi (i-WLABs) zisetyenziselwa iibhetri ze-asidi ezifuna ukulahlwa. 

Phakathi kweendlela ezahlukeneyo zokusetyenziswa kwee-WLABs, esona sicelo singundoqo sihlala sisezimotweni, ngelixa ukusetyenziswa kombane ongaphazamisekiyo kwi-UPS yinto evelayo ngenxa yokukhula kumacandelo onxibelelwano kunye neTekhnoloji yoLwazi (ingakumbi amaziko edatha).Ngokunyuka kwenani lamaziko edatha, kulindeleke ukuba ii-WLABs ezivela kweli candelo ziya kuqhubeka ukwanda kwiminyaka ezayo.

Singanikezela ngegqibezela umgca wokurisayikilisha iibhetri zeasidi, kubandakanywa inkqubo yokuqhawula kunye nokwahlula, inkqubo yesithando somlilo, inkqubo yokucoca, kunye nenkqubo yokucoca igesi yomsila, njl.

Ulwazi oluthe vetshe, nceda uzive ukhululekile ukuqhagamshelana nathi.
