很多對電(dian)(dian)池不了(le)解的朋友可能不知道的是鎳氫電(dian)(dian)池在耐過(guo)充和(he)耐過(guo)放(fang)電(dian)(dian)性能方面要比(bi)鋰電(dian)(dian)池好，下面給大家簡單介紹一下為什么鎳氫電(dian)(dian)池耐過(guo)充和(he)耐過(guo)放(fang)電(dian)(dian)。

NiMH(NiCd)是由(you)鎳(nie)(nie)鎘電(dian)(dian)(dian)池(NiCd)改(gai)進而(er)成(cheng)(cheng)。其電(dian)(dian)(dian)容(rong)比鎳(nie)(nie)鎘電(dian)(dian)(dian)池更(geng)大(da)，記憶(yi)效果(guo)不(bu)明顯，而(er)且成(cheng)(cheng)本也不(bu)高(不(bu)含鎘Cd)，而(er)且還能降低環(huan)境污染。人們稱之(zhi)為最環(huan)保的電(dian)(dian)(dian)池。但與鋰離子電(dian)(dian)(dian)池相比，記憶(yi)效應更(geng)強(qiang)，自放電(dian)(dian)(dian)反應也更(geng)強(qiang)。鎳(nie)(nie)氫化(hua)物電(dian)(dian)(dian)池適(shi)用于高能耗產(chan)品，如數碼(ma)相機(ji)，而(er)鎳(nie)(nie)鎘電(dian)(dian)(dian)池則(ze)適(shi)用于需(xu)要高放電(dian)(dian)(dian)率的設備(bei)。

鎳氫充電電池耐過充原因

日常使用的1.2V鎳氫電池，其(qi)充滿電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)通(tong)常為1.4V，放電(dian)(dian)(dian)(dian)終止電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)是(shi)0.9V。這(zhe)就(jiu)意味著，鎳氫(qing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)在放電(dian)(dian)(dian)(dian)到0.9V時已經不便使用(yong)，應(ying)該充電(dian)(dian)(dian)(dian)了。因(yin)此(ci)，0.9V既是(shi)放電(dian)(dian)(dian)(dian)時的(de)(de)終止電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，也可以看作是(shi)鎳氫(qing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充電(dian)(dian)(dian)(dian)的(de)(de)起始電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)。實用(yong)中(zhong)，因(yin)為0.9V之后的(de)(de)鎳氫(qing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)還有一些小電(dian)(dian)(dian)(dian)流(liu)存在，所以，有的(de)(de)鎳氫(qing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)將起始電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)設(she)置為0.8V也是(shi)可行的(de)(de)。鎳氫(qing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)充滿后的(de)(de)電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)在1.4V左右(you)，這(zhe)可以視(shi)(shi)為其(qi)最高電(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)(ya)，但個(ge)體電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)也要視(shi)(shi)具體充電(dian)(dian)(dian)(dian)方(fang)式而定。

一(yi)種情況是以恒壓(ya)充電(dian)，比較老(lao)式的充電(dian)方式仍然這樣(yang)設置，一(yi)般(ban)都(dou)是設置為1.4V，但這樣(yang)的后(hou)果有可(ke)(ke)能是電(dian)池到達1.4V可(ke)(ke)能還沒有充飽，在這種情況下，鎳氫電(dian)池充電(dian)終(zhong)止電(dian)壓(ya)就不是鎳氫電(dian)池飽和電(dian)壓(ya)。

在(zai)快(kuai)速充(chong)電(dian)時，可透過充(chong)電(dian)器內部的微電(dian)腦來避免電(dian)池過充(chong)。現在(zai)的鎳氫電(dian)池包含一個(ge)催化劑(ji)，它可以及時解除由(you)于(yu)過充(chong)而產生(sheng)的危險。

剛買回(hui)來的(de)或(huo)者是沒用過很久的(de)鎳氫(qing)電池，需要一個(ge)“激活”的(de)時間才能恢復電量(liang)。所以，有(you)些(xie)新的(de)鎳氫(qing)電池需要經過幾個(ge)充放電循環，才能達到其規定的(de)電量(liang)。

在過(guo)(guo)(guo)充(chong)和過(guo)(guo)(guo)放電(dian)(dian)(dian)過(guo)(guo)(guo)程中，由于儲氫(qing)合(he)(he)金粉的(de)(de)催化(hua)作(zuo)用，可(ke)(ke)以(yi)(yi)消耗正(zheng)極(ji)產生的(de)(de)氧(yang)氣和氫(qing)氣，從(cong)而(er)(er)使鎳氫(qing)電(dian)(dian)(dian)池(chi)(chi)具有耐過(guo)(guo)(guo)充(chong)過(guo)(guo)(guo)放電(dian)(dian)(dian)的(de)(de)能力。在充(chong)電(dian)(dian)(dian)末(mo)期和過(guo)(guo)(guo)充(chong)電(dian)(dian)(dian)時，正(zheng)極(ji)上析(xi)出(chu)(chu)的(de)(de)O2可(ke)(ke)以(yi)(yi)通過(guo)(guo)(guo)隔膜擴(kuo)散到負極(ji)表(biao)面與氫(qing)復合(he)(he)，還(huan)原為H2O和OH-進入電(dian)(dian)(dian)解液，從(cong)而(er)(er)避免或減輕了(le)電(dian)(dian)(dian)池(chi)(chi)內部壓力積累升高的(de)(de)現象。否則(ze)，在電(dian)(dian)(dian)池(chi)(chi)過(guo)(guo)(guo)充(chong)時，MH電(dian)(dian)(dian)極(ji)又會產生大量(liang)氫(qing)氣，造成電(dian)(dian)(dian)池(chi)(chi)內壓上升;而(er)(er)在過(guo)(guo)(guo)放電(dian)(dian)(dian)時，正(zheng)極(ji)上析(xi)出(chu)(chu)的(de)(de)H2通過(guo)(guo)(guo)隔膜擴(kuo)散到負極(ji)表(biao)面可(ke)(ke)以(yi)(yi)被MH迅速吸收(shou)，否則(ze)，在電(dian)(dian)(dian)池(chi)(chi)過(guo)(guo)(guo)放電(dian)(dian)(dian)時，MH電(dian)(dian)(dian)極(ji)上會析(xi)出(chu)(chu)O2,從(cong)而(er)(er)使MH合(he)(he)金被氧(yang)化(hua)。
