Amabhethri e-lead acid

Ibhethri le-lead-acid

Iibhethri le-lead-acidiwuhlobo lwebhethri elishajekayo elasungulwa okokuqala ngo-1859 ngusosayensi waseFrance u-Gaston Planté.Ngesokuqalaumusayebhethri elishajekayokudaliwe.Uma kuqhathaniswa namabhethri esimanjemanje ashajwa kabusha, amabhethri omthofu-asidi anomthamo wamandla aphansi uma kuqhathaniswa.Naphezu kwalokhu, ikhono lawo lokuhlinzeka ngemisinga ephezulu yokukhuphuka lisho ukuthi amaseli anesilinganiso esikhulu samandla nesisindo.Lezi zici, kanye nezindleko zazo eziphansi, zizenza zikhange ukusetshenziswa ezimotweni ukuze zinikeze amandla amanje aphezulu adingwa ama-starter motor.Amabhethri e-lead-acid ahlushwa ubude besikhathi sokuphila komjikelezo omfushane uma kuqhathaniswa (imvamisa engaphansi kwemijikelezo ejulile engu-500) kanye nesikhathi sonke sokuphila (ngenxa “yokucwecwa okuphindwe kabili” esimweni sokushajwa).

Gel-amaselifuthiamuncwa ingilazi-matamabhethri avamile kulezi zindima, ngokuhlanganyela ezaziwa ngokuthi amabhethri e-VRLA (i-valve-regulated lead–acid).

Esimeni sokushajwa, amandla ekhemikhali ebhethri agcinwa kumehluko ongaba khona phakathi komthofu wensimbi ohlangothini olunegethivu kanye ne-PbO.₂ohlangothini oluhle.Iqukethe uhlangothi oluhle lwe-PbO2 kanye ne-negtive metallic lead, ibhodi lokufakwa ngaphakathi, ikesi lepulasitiki, i-sulfuric acid namanzi.

Lapho ukhipha, ukusabela okuhle kwe-electrode:bO2 + 4H+ + SO42- + 2e- = PbSO4 + 2H2O

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

Ukusabela sekukonke: PbO2 + Pb + 2H2SO4 === 2PbSO4 + 2H2O (Ukusabela kwesokudla kuwukukhipha, ukusabela kwesokunxele kuyashaja).

Amabhethri e-waste lead-acid (WLABs) asetshenziswa amabhethri e-lead-acid adinga ukulahlwa. 

Phakathi kokusetshenziswa okuhlukene kwama-WLAB, isicelo esikhulu kusasele esokuba ezimotweni, kanti ukusetshenziswa kukagesi ongaphazamiseki e-UPS kuwumkhuba osavelayo ngenxa yokukhula emikhakheni yezokuxhumana nobuchwepheshe bolwazi (ikakhulukazi izikhungo zedatha).Ngokukhula kwesibalo sezikhungo zedatha, kulindeleke ukuthi ama-WLAB avela kulo mkhakha aqhubeke nokukhula eminyakeni ezayo.

Singanikela aqedela ulayini wokugaya kabusha amabhethri e-lead acid, okuhlanganisa uhlelo lokuphuka nokuhlukanisa, isistimu yesithando somlilo, isistimu yokucwenga, nesistimu yokuhlunga igesi yomsila, njll.

Ulwazi olwengeziwe, sicela ukhululeke ukuxhumana nathi.

Ngiyanibingelela,
