電池為什么會鼓包?

2021-03-16 16:50:10 admin 3

電池(chi)鼓包(bao)原因一:長時(shi)間充電,正負極產生化學反應

當電(dian)(dian)池(chi)單格工作(zuo)電(dian)(dian)壓到達2.3V以上的(de)時候,電(dian)(dian)池(chi)便(bian)(bian)會(hui)進行析(xi)(xi)出氣(qi)體(ti)(ti)(鉛鈣極(ji)(ji)板的(de)析(xi)(xi)氣(qi)工作(zuo)電(dian)(dian)壓為(wei)2.3V,鉛銻極(ji)(ji)板的(de)析(xi)(xi)氣(qi)工作(zuo)電(dian)(dian)壓為(wei)2.35V)。大家(jia)都(dou)知道,當水(shui)燒(shao)開后的(de)水(shui)蒸(zheng)汽(qi)是十(shi)分熱的(de),另外(wai)力量也(ye)是十(shi)分大的(de),能夠(gou) 運行一(yi)輛(liang)火車(蒸(zheng)汽(qi)車)。這個理論用到我們(men)電(dian)(dian)池(chi)是上也(ye)是一(yi)樣的(de),當析(xi)(xi)氣(qi)時,電(dian)(dian)池(chi)溫度(du)便(bian)(bian)會(hui)增大,另外(wai)要是大量析(xi)(xi)氣(qi)便(bian)(bian)會(hui)造(zao)(zao)成 電(dian)(dian)池(chi)內部(bu)沒(mei)有足夠(gou)的(de)空(kong)間去儲放這些氣(qi)體(ti)(ti),便(bian)(bian)會(hui)造(zao)(zao)成 電(dian)(dian)池(chi)鼓(gu)脹。

電(dian)(dian)池鼓包原因二:電(dian)(dian)池內阻過高,產生(sheng)發(fa)熱現象

電(dian)(dian)池內阻過高(gao)。當一塊電(dian)(dian)池內阻過高(gao)的時(shi)候,當電(dian)(dian)流一定的情(qing)況(kuang)下,工(gong)(gong)作(zuo)電(dian)(dian)壓便(bian)會很高(gao)(工(gong)(gong)作(zuo)電(dian)(dian)壓=電(dian)(dian)流*電(dian)(dian)阻)。我們可以(yi)看到的是(shi)普通充電(dian)(dian)時(shi)紅燈還(huan)沒有跳轉(zhuan)電(dian)(dian)池就(jiu)(jiu)很熱(re)了(le),即電(dian)(dian)池還(huan)沒有到達(da)充電(dian)(dian)工(gong)(gong)作(zuo)電(dian)(dian)壓,就(jiu)(jiu)提前析氣了(le)!

電(dian)池鼓包原因二:電(dian)池內(nei)阻過(guo)高(gao),產生發熱(re)現象

電(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)器的電(dian)(dian)壓電(dian)(dian)流不(bu)滿足要求。當我們使用的電(dian)(dian)池(chi)(chi)充(chong)電(dian)(dian)器基(ji)本(ben)(ben)參(can)數高于我們電(dian)(dian)池(chi)(chi)額定的電(dian)(dian)壓電(dian)(dian)流等基(ji)本(ben)(ben)參(can)數的情況下,就會有(you)可能將電(dian)(dian)池(chi)(chi)充(chong)鼓!

鋰電池(chi)鼓包了怎么辦呢?

1,通(tong)常情(qing)況下,在充(chong)電(dian)(dian)時(shi),要(yao)(yao)特別注意充(chong)電(dian)(dian)器(qi)的選(xuan)取(qu),規格(ge),電(dian)(dian)池的額定(ding)值充(chong)電(dian)(dian)電(dian)(dian)壓(ya)是3.7v,終極電(dian)(dian)壓(ya)為4.2v,要(yao)(yao)盡(jin)可能的不可以選(xuan)取(qu)達到(dao)該電(dian)(dian)壓(ya)的充(chong)電(dian)(dian)器(qi),能夠 維(wei)持恒定(ding)電(dian)(dian)流為最合適(shi)。

2,鋰(li)電(dian)(dian)池(chi)包大部分須(xu)要技術(shu)專業的(de)回(hui)收利用處(chu)置才不容易對自(zi)然環(huan)境引起環(huan)境污(wu)染,故此(ci)最(zui)好(hao)的(de)選擇將其(qi)遺(yi)棄到(dao)技術(shu)專業處(chu)置鋰(li)電(dian)(dian)池(chi)包的(de)經營場所。假如本地都沒有這類地區的(de)情況(kuang)下,最(zui)佳(jia)的(de)方式(shi) 便是(shi)將其(qi)扔到(dao)廢(fei)舊電(dian)(dian)池(chi)的(de)分類回(hui)收利用垃圾箱(xiang)里。
