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)結束后不能再(zai)通(tong)過(guo)充電(dian)(dian)使其(qi)(qi)復原(yuan)，再(zai)度(du)使用(yong)的電(dian)(dian)池(chi)，這(zhe)種電(dian)(dian)池(chi)通(tong)常只(zhi)能一次性(xing)使用(yong)，無(wu)法(fa)通(tong)過(guo)充電(dian)(dian)或其(qi)(qi)它方(fang)式將(jiang)原(yuan)有(you)電(dian)(dian)能補充回來。

一次電(dian)池(chi)一般用完即廢，這一特性是(shi)它(ta)的(de)電(dian)池(chi)反(fan)應或(huo)電(dian)極反(fan)應的(de)不可(ke)逆性或(huo)條件，限(xian)制使電(dian)池(chi)反(fan)應很難可(ke)逆地進行所決定的(de)。

二、干電池是一次性電池嗎

是的。

干電(dian)(dian)(dian)池(chi)(chi)的(de)原(yuan)理是利(li)用氧化還原(yuan)反(fan)應將(jiang)化學(xue)能轉化為電(dian)(dian)(dian)能，這一化學(xue)反(fan)應是不(bu)可逆的(de)，不(bu)能進行充電(dian)(dian)(dian)和(he)放電(dian)(dian)(dian)循環使(shi)用，因此屬于(yu)一次(ci)性電(dian)(dian)(dian)池(chi)(chi)。除了干電(dian)(dian)(dian)池(chi)(chi)外(wai)，常見的(de)碳鋅電(dian)(dian)(dian)池(chi)(chi)、堿性電(dian)(dian)(dian)池(chi)(chi)、水銀電(dian)(dian)(dian)池(chi)(chi)、鋅空(kong)氣電(dian)(dian)(dian)池(chi)(chi)等都屬于(yu)一次(ci)電(dian)(dian)(dian)池(chi)(chi)。

三、一次電池和二次電池的區別

和一(yi)次(ci)電(dian)池(chi)(chi)相對的，二次(ci)電(dian)池(chi)(chi)就是指可以通過充電(dian)或其他方式補充電(dian)能的電(dian)池(chi)(chi)，這兩(liang)種電(dian)池(chi)(chi)的區別主(zhu)要有：

1、二次(ci)電池在放(fang)電時電極體(ti)積和結構(gou)之間發(fa)生可逆變(bian)化，而一次(ci)電池內部則簡單得多，因為它不需要調節這些可逆性變(bian)化。

2、一次電池(chi)的(de)質(zhi)量比容(rong)量和體(ti)積(ji)比容(rong)量均大于普通充電電池(chi)，但(dan)內阻遠(yuan)比二次電池(chi)大，因此負載能(neng)力(li)較低。

3、一次電池的(de)自(zi)放電(dian)遠小于二(er)次(ci)電(dian)池(chi)。一次(ci)電(dian)池(chi)只(zhi)能(neng)放電(dian)一次(ci)，如(ru)，堿性電(dian)池(chi)和碳性電(dian)池(chi)就屬于此(ci)類，二(er)次(ci)電(dian)池(chi)可反復(fu)循(xun)環使用。

4、一次電(dian)(dian)池(chi)內阻遠大二(er)次電(dian)(dian)池(chi)，其大電(dian)(dian)流放(fang)電(dian)(dian)性能亦不及二(er)次電(dian)(dian)池(chi)，在(zai)小電(dian)(dian)流、間歇性放(fang)電(dian)(dian)的(de)條件(jian)下，一次電(dian)(dian)池(chi)的(de)質量(liang)(liang)比容量(liang)(liang)大于普通二(er)次電(dian)(dian)池(chi)，但當放(fang)電(dian)(dian)電(dian)(dian)流大于800mAh，則一次電(dian)(dian)池(chi)的(de)容量(liang)(liang)優勢就會明顯減小。

5、二次(ci)(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)相(xiang)對一次(ci)(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)更環(huan)保。一次(ci)(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)使用(yong)后就(jiu)必須廢(fei)棄，而充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)可(ke)反復(fu)使用(yong)，符(fu)合國家標準(zhun)的(de)(de)次(ci)(ci)(ci)世(shi)代充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)通常可(ke)反復(fu)使用(yong)1000次(ci)(ci)(ci)以上(shang)，也就(jiu)是說充電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)(chi)產生的(de)(de)廢(fei)棄物(wu)不(bu)到一次(ci)(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)1000分之1，不(bu)論(lun)從(cong)減少(shao)廢(fei)棄物(wu)還是從(cong)資源利用(yong)及經(jing)濟的(de)(de)角(jiao)度來(lai)考慮，二次(ci)(ci)(ci)電(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)優越(yue)性都是十分明顯的(de)(de)。
