一、一次電池是什么意思

一次電池，也叫一次性電池，是指放電(dian)(dian)(dian)結束(shu)后(hou)不能再(zai)通(tong)過充電(dian)(dian)(dian)使(shi)其(qi)復原(yuan)，再(zai)度使(shi)用的電(dian)(dian)(dian)池，這種電(dian)(dian)(dian)池通(tong)常只能一次性使(shi)用，無(wu)法通(tong)過充電(dian)(dian)(dian)或其(qi)它方式將(jiang)原(yuan)有(you)電(dian)(dian)(dian)能補充回來。

一次電(dian)池(chi)一般用完即廢(fei)，這一特性是(shi)它的(de)電(dian)池(chi)反應或(huo)電(dian)極反應的(de)不可逆性或(huo)條件(jian)，限(xian)制使電(dian)池(chi)反應很(hen)難可逆地進行所決定(ding)的(de)。

二、干電池是一次性電池嗎

是的。

干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)原理是(shi)利用氧化(hua)還原反(fan)應將化(hua)學能(neng)(neng)轉化(hua)為電(dian)(dian)(dian)(dian)能(neng)(neng)，這一(yi)化(hua)學反(fan)應是(shi)不可逆的(de)(de)，不能(neng)(neng)進(jin)行充電(dian)(dian)(dian)(dian)和(he)放電(dian)(dian)(dian)(dian)循環使用，因此屬于(yu)一(yi)次(ci)性電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。除了干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)外，常(chang)見的(de)(de)碳鋅電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、堿(jian)性電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、水銀(yin)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、鋅空氣電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)等都屬于(yu)一(yi)次(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。

三、一次電池和二次電池的區別

和(he)一次電(dian)(dian)池(chi)相對的，二次電(dian)(dian)池(chi)就是指可(ke)以通(tong)過充(chong)電(dian)(dian)或(huo)其(qi)他方式補(bu)充(chong)電(dian)(dian)能的電(dian)(dian)池(chi)，這兩種(zhong)電(dian)(dian)池(chi)的區別主要有：

1、二(er)次電池在放電時電極體積(ji)和結(jie)構之間發生可(ke)逆變(bian)化，而一次電池內部則簡單得多，因為它不需要調節(jie)這些可(ke)逆性變(bian)化。

2、一次(ci)電(dian)池的(de)質量(liang)比(bi)容(rong)量(liang)和體積比(bi)容(rong)量(liang)均大于普通充電(dian)電(dian)池，但(dan)內(nei)阻遠比(bi)二次(ci)電(dian)池大，因此負(fu)載能力較低。

3、一次電池的自放電(dian)(dian)遠小于(yu)二(er)次(ci)(ci)電(dian)(dian)池(chi)(chi)。一次(ci)(ci)電(dian)(dian)池(chi)(chi)只(zhi)能放電(dian)(dian)一次(ci)(ci)，如，堿性電(dian)(dian)池(chi)(chi)和碳性電(dian)(dian)池(chi)(chi)就屬于(yu)此類，二(er)次(ci)(ci)電(dian)(dian)池(chi)(chi)可反復循(xun)環(huan)使用。

4、一次(ci)電(dian)池(chi)內阻遠大(da)二次(ci)電(dian)池(chi)，其大(da)電(dian)流放(fang)(fang)電(dian)性(xing)能(neng)亦(yi)不及二次(ci)電(dian)池(chi)，在小電(dian)流、間(jian)歇性(xing)放(fang)(fang)電(dian)的條件下，一次(ci)電(dian)池(chi)的質量比容(rong)量大(da)于普通二次(ci)電(dian)池(chi)，但當(dang)放(fang)(fang)電(dian)電(dian)流大(da)于800mAh，則一次(ci)電(dian)池(chi)的容(rong)量優(you)勢(shi)就會明(ming)顯(xian)減小。

5、二次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)相(xiang)對(dui)一(yi)次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)更環保。一(yi)次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)使(shi)用后就(jiu)(jiu)必須廢棄，而充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)可(ke)反復使(shi)用，符合國家標準的次(ci)(ci)世代充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)通常可(ke)反復使(shi)用1000次(ci)(ci)以(yi)上，也就(jiu)(jiu)是(shi)說(shuo)充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)產(chan)生的廢棄物不(bu)到一(yi)次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)的1000分之1，不(bu)論(lun)從減少廢棄物還(huan)是(shi)從資源利(li)用及經濟(ji)的角度來考慮，二次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)的優(you)越(yue)性都是(shi)十(shi)分明(ming)顯的。
