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)結束(shu)后不能(neng)再通過(guo)充(chong)(chong)電(dian)使其(qi)復(fu)原，再度使用的電(dian)池(chi)，這種電(dian)池(chi)通常(chang)只能(neng)一次性使用，無法(fa)通過(guo)充(chong)(chong)電(dian)或(huo)其(qi)它(ta)方式將原有電(dian)能(neng)補充(chong)(chong)回來。

一(yi)次電池(chi)一(yi)般用完即廢，這(zhe)一(yi)特(te)性(xing)是它的(de)電池(chi)反(fan)(fan)應(ying)或(huo)電極反(fan)(fan)應(ying)的(de)不可逆性(xing)或(huo)條件，限制使電池(chi)反(fan)(fan)應(ying)很難可逆地進行(xing)所決定的(de)。

二、干電池是一次性電池嗎

是的。

干(gan)電(dian)(dian)(dian)(dian)(dian)池的(de)(de)原(yuan)理是利(li)用氧化(hua)還原(yuan)反應(ying)(ying)將化(hua)學(xue)能(neng)轉(zhuan)化(hua)為電(dian)(dian)(dian)(dian)(dian)能(neng)，這一化(hua)學(xue)反應(ying)(ying)是不可逆(ni)的(de)(de)，不能(neng)進行(xing)充電(dian)(dian)(dian)(dian)(dian)和放電(dian)(dian)(dian)(dian)(dian)循(xun)環使用，因此屬(shu)于一次性電(dian)(dian)(dian)(dian)(dian)池。除了干(gan)電(dian)(dian)(dian)(dian)(dian)池外，常(chang)見(jian)的(de)(de)碳鋅(xin)電(dian)(dian)(dian)(dian)(dian)池、堿性電(dian)(dian)(dian)(dian)(dian)池、水銀電(dian)(dian)(dian)(dian)(dian)池、鋅(xin)空氣電(dian)(dian)(dian)(dian)(dian)池等都(dou)屬(shu)于一次電(dian)(dian)(dian)(dian)(dian)池。

三、一次電池和二次電池的區別

和一(yi)次電(dian)(dian)池(chi)(chi)相對(dui)的(de)，二(er)次電(dian)(dian)池(chi)(chi)就是指可以通(tong)過充(chong)電(dian)(dian)或其他方式補充(chong)電(dian)(dian)能的(de)電(dian)(dian)池(chi)(chi)，這(zhe)兩種電(dian)(dian)池(chi)(chi)的(de)區別(bie)主要有：

1、二次(ci)電池在放電時電極體積和結構之間發生可(ke)逆變化(hua)，而一次(ci)電池內部則(ze)簡(jian)單得多，因為它不需要調節這些可(ke)逆性變化(hua)。

2、一次(ci)(ci)電池(chi)的質(zhi)量(liang)(liang)比(bi)容(rong)量(liang)(liang)和體積(ji)比(bi)容(rong)量(liang)(liang)均大(da)于普通(tong)充電電池(chi)，但內阻(zu)遠比(bi)二次(ci)(ci)電池(chi)大(da)，因(yin)此(ci)負載能力較低。

3、一次電池的自(zi)放電(dian)遠小于(yu)二次電(dian)池(chi)(chi)(chi)。一(yi)(yi)次電(dian)池(chi)(chi)(chi)只(zhi)能(neng)放電(dian)一(yi)(yi)次，如，堿性電(dian)池(chi)(chi)(chi)和(he)碳性電(dian)池(chi)(chi)(chi)就(jiu)屬于(yu)此類，二次電(dian)池(chi)(chi)(chi)可反復循環使用。

4、一次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)內阻遠大(da)二次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)，其(qi)大(da)電(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)性能亦不(bu)及二次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)，在(zai)小電(dian)(dian)(dian)(dian)流、間歇性放(fang)電(dian)(dian)(dian)(dian)的(de)(de)(de)條件下，一次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)質(zhi)量比(bi)容量大(da)于普通二次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)，但當放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流大(da)于800mAh，則一次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)容量優勢就會明顯(xian)減小。

5、二次電(dian)(dian)池(chi)(chi)(chi)(chi)相對一次電(dian)(dian)池(chi)(chi)(chi)(chi)更環(huan)保。一次電(dian)(dian)池(chi)(chi)(chi)(chi)使用(yong)后就必須廢(fei)(fei)棄，而充(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)(chi)可(ke)反復使用(yong)，符合國家標(biao)準(zhun)的(de)(de)次世(shi)代充(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)(chi)通常可(ke)反復使用(yong)1000次以上，也就是說充(chong)電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)(chi)產生的(de)(de)廢(fei)(fei)棄物不到一次電(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)1000分之1，不論從減(jian)少廢(fei)(fei)棄物還是從資源利用(yong)及經(jing)濟(ji)的(de)(de)角(jiao)度來(lai)考慮(lv)，二次電(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)優越性都是十分明顯的(de)(de)。
