一、一次電池是什么意思

一次電池，也叫一次性電池，是指(zhi)放電(dian)結束后(hou)不能再通(tong)過(guo)充(chong)電(dian)使(shi)(shi)(shi)其(qi)復原(yuan)，再度(du)使(shi)(shi)(shi)用(yong)的電(dian)池(chi)，這種電(dian)池(chi)通(tong)常只能一(yi)次性使(shi)(shi)(shi)用(yong)，無法通(tong)過(guo)充(chong)電(dian)或(huo)其(qi)它方式將原(yuan)有電(dian)能補(bu)充(chong)回來。

一次(ci)電(dian)池一般用完即(ji)廢(fei)，這一特性是它的(de)電(dian)池反應或電(dian)極反應的(de)不可逆性或條件，限(xian)制使(shi)電(dian)池反應很(hen)難(nan)可逆地進行所決(jue)定的(de)。

二、干電池是一次性電池嗎

是的。

干(gan)電(dian)(dian)池(chi)(chi)的(de)原理是利用(yong)氧化(hua)還原反(fan)應將化(hua)學能轉化(hua)為電(dian)(dian)能，這一化(hua)學反(fan)應是不可逆的(de)，不能進(jin)行充電(dian)(dian)和放電(dian)(dian)循環使用(yong)，因(yin)此(ci)屬于(yu)一次(ci)性電(dian)(dian)池(chi)(chi)。除了干(gan)電(dian)(dian)池(chi)(chi)外(wai)，常見的(de)碳鋅電(dian)(dian)池(chi)(chi)、堿性電(dian)(dian)池(chi)(chi)、水銀電(dian)(dian)池(chi)(chi)、鋅空(kong)氣電(dian)(dian)池(chi)(chi)等都(dou)屬于(yu)一次(ci)電(dian)(dian)池(chi)(chi)。

三、一次電池和二次電池的區別

和一次(ci)電(dian)池(chi)相對的，二次(ci)電(dian)池(chi)就是指可以通過充電(dian)或其他方式(shi)補充電(dian)能的電(dian)池(chi)，這兩種電(dian)池(chi)的區別主要(yao)有：

1、二次電(dian)池在放電(dian)時(shi)電(dian)極體積(ji)和結構之間發(fa)生可逆變(bian)化，而一次電(dian)池內(nei)部則(ze)簡單得多，因為它不需要調節這些可逆性變(bian)化。

2、一(yi)次(ci)(ci)電(dian)池(chi)的質量比容(rong)量和體積(ji)比容(rong)量均大(da)于普(pu)通(tong)充(chong)電(dian)電(dian)池(chi)，但內阻遠比二(er)次(ci)(ci)電(dian)池(chi)大(da)，因(yin)此負載能力較低。

3、一次電池的自放(fang)(fang)電(dian)遠小于(yu)二(er)次電(dian)池(chi)。一(yi)次電(dian)池(chi)只(zhi)能放(fang)(fang)電(dian)一(yi)次，如，堿(jian)性電(dian)池(chi)和碳性電(dian)池(chi)就屬于(yu)此類，二(er)次電(dian)池(chi)可反復循環使用。

4、一(yi)次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)內(nei)阻(zu)遠大(da)(da)(da)二(er)(er)次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)，其大(da)(da)(da)電(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)性能(neng)亦不(bu)及二(er)(er)次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)，在小電(dian)(dian)(dian)流(liu)、間(jian)歇(xie)性放電(dian)(dian)(dian)的條(tiao)件下，一(yi)次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)的質量(liang)比容量(liang)大(da)(da)(da)于(yu)普通二(er)(er)次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)，但當放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)大(da)(da)(da)于(yu)800mAh，則一(yi)次(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)的容量(liang)優(you)勢就會明顯減(jian)小。

5、二(er)(er)次(ci)電(dian)(dian)池(chi)相對一(yi)次(ci)電(dian)(dian)池(chi)更環保(bao)。一(yi)次(ci)電(dian)(dian)池(chi)使(shi)用后就(jiu)必須廢(fei)棄，而充電(dian)(dian)電(dian)(dian)池(chi)可(ke)反復使(shi)用，符合國(guo)家標準的(de)(de)(de)次(ci)世(shi)代充電(dian)(dian)電(dian)(dian)池(chi)通常可(ke)反復使(shi)用1000次(ci)以上，也就(jiu)是說充電(dian)(dian)電(dian)(dian)池(chi)產生(sheng)的(de)(de)(de)廢(fei)棄物不到一(yi)次(ci)電(dian)(dian)池(chi)的(de)(de)(de)1000分之1，不論從減少廢(fei)棄物還是從資源利用及(ji)經濟(ji)的(de)(de)(de)角度來考慮，二(er)(er)次(ci)電(dian)(dian)池(chi)的(de)(de)(de)優越性都是十分明(ming)顯的(de)(de)(de)。
