一、一次電池是什么意思

一次電池，也叫一次性電池，是指放(fang)電結束后不(bu)能再通過充(chong)電使(shi)其(qi)復原(yuan)(yuan)，再度使(shi)用(yong)(yong)的電池(chi)，這種電池(chi)通常只能一次性使(shi)用(yong)(yong)，無(wu)法通過充(chong)電或其(qi)它(ta)方式將原(yuan)(yuan)有電能補充(chong)回來。

一次電(dian)(dian)池一般用(yong)完即廢，這一特性是(shi)它的電(dian)(dian)池反應或電(dian)(dian)極反應的不可逆性或條(tiao)件，限制使(shi)電(dian)(dian)池反應很難(nan)可逆地(di)進行所決定的。

二、干電池是一次性電池嗎

是的。

干(gan)電(dian)(dian)(dian)(dian)池的原(yuan)(yuan)理(li)是利(li)用(yong)氧化(hua)(hua)(hua)還(huan)原(yuan)(yuan)反應(ying)將化(hua)(hua)(hua)學能(neng)轉化(hua)(hua)(hua)為電(dian)(dian)(dian)(dian)能(neng)，這一(yi)化(hua)(hua)(hua)學反應(ying)是不可逆的，不能(neng)進行充(chong)電(dian)(dian)(dian)(dian)和放(fang)電(dian)(dian)(dian)(dian)循環(huan)使(shi)用(yong)，因此屬于一(yi)次(ci)(ci)性(xing)電(dian)(dian)(dian)(dian)池。除了干(gan)電(dian)(dian)(dian)(dian)池外，常(chang)見(jian)的碳鋅電(dian)(dian)(dian)(dian)池、堿性(xing)電(dian)(dian)(dian)(dian)池、水銀電(dian)(dian)(dian)(dian)池、鋅空氣電(dian)(dian)(dian)(dian)池等都屬于一(yi)次(ci)(ci)電(dian)(dian)(dian)(dian)池。

三、一次電池和二次電池的區別

和一次電(dian)(dian)池相對(dui)的，二次電(dian)(dian)池就是指可以通過充電(dian)(dian)或其他方式補(bu)充電(dian)(dian)能(neng)的電(dian)(dian)池，這(zhe)兩(liang)種電(dian)(dian)池的區別主(zhu)要有：

1、二次電(dian)池(chi)在放電(dian)時電(dian)極體(ti)積和(he)結構之間發生可逆變化，而一次電(dian)池(chi)內部(bu)則簡(jian)單得多，因為它不需要調節這些可逆性變化。

2、一次(ci)電池(chi)的質量(liang)(liang)比(bi)容(rong)量(liang)(liang)和體積比(bi)容(rong)量(liang)(liang)均(jun)大于(yu)普通充(chong)電電池(chi)，但內阻(zu)遠比(bi)二次(ci)電池(chi)大，因此負載能(neng)力較(jiao)低。

3、一次電池的自放電(dian)遠小于二次(ci)電(dian)池。一次(ci)電(dian)池只(zhi)能放電(dian)一次(ci)，如，堿性電(dian)池和(he)碳性電(dian)池就屬于此類，二次(ci)電(dian)池可反復循(xun)環使用。

4、一次(ci)電(dian)(dian)(dian)池(chi)(chi)內阻遠大(da)二(er)次(ci)電(dian)(dian)(dian)池(chi)(chi)，其大(da)電(dian)(dian)(dian)流(liu)放電(dian)(dian)(dian)性(xing)能(neng)亦不及二(er)次(ci)電(dian)(dian)(dian)池(chi)(chi)，在小電(dian)(dian)(dian)流(liu)、間歇性(xing)放電(dian)(dian)(dian)的條件下，一次(ci)電(dian)(dian)(dian)池(chi)(chi)的質量比容(rong)量大(da)于普通二(er)次(ci)電(dian)(dian)(dian)池(chi)(chi)，但當放電(dian)(dian)(dian)電(dian)(dian)(dian)流(liu)大(da)于800mAh，則一次(ci)電(dian)(dian)(dian)池(chi)(chi)的容(rong)量優勢就會明顯減小。

5、二次(ci)電(dian)(dian)池(chi)(chi)相對一(yi)次(ci)電(dian)(dian)池(chi)(chi)更(geng)環(huan)保。一(yi)次(ci)電(dian)(dian)池(chi)(chi)使用(yong)后就必須廢棄，而充電(dian)(dian)電(dian)(dian)池(chi)(chi)可反復使用(yong)，符合國家標準的(de)(de)次(ci)世代充電(dian)(dian)電(dian)(dian)池(chi)(chi)通常可反復使用(yong)1000次(ci)以上，也就是(shi)說(shuo)充電(dian)(dian)電(dian)(dian)池(chi)(chi)產(chan)生的(de)(de)廢棄物(wu)不到一(yi)次(ci)電(dian)(dian)池(chi)(chi)的(de)(de)1000分之1，不論從減少廢棄物(wu)還(huan)是(shi)從資源利用(yong)及經濟的(de)(de)角度來考慮，二次(ci)電(dian)(dian)池(chi)(chi)的(de)(de)優越性都是(shi)十(shi)分明顯(xian)的(de)(de)。
