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)結束后不能再通過充(chong)電(dian)(dian)(dian)使(shi)其復原，再度使(shi)用的電(dian)(dian)(dian)池，這(zhe)種電(dian)(dian)(dian)池通常(chang)只能一次性使(shi)用，無法(fa)通過充(chong)電(dian)(dian)(dian)或其它方式(shi)將原有電(dian)(dian)(dian)能補充(chong)回來。

一次電(dian)池一般用完(wan)即廢，這一特(te)性(xing)是(shi)它(ta)的電(dian)池反應或(huo)電(dian)極反應的不(bu)可逆性(xing)或(huo)條件，限制(zhi)使電(dian)池反應很難(nan)可逆地進行(xing)所決定的。

二、干電池是一次性電池嗎

是的。

干電(dian)池(chi)(chi)的(de)原理是(shi)利用氧化還原反(fan)應(ying)將(jiang)化學能轉化為(wei)電(dian)能，這(zhe)一化學反(fan)應(ying)是(shi)不(bu)可逆(ni)的(de)，不(bu)能進行充電(dian)和放電(dian)循(xun)環使用，因此屬(shu)于(yu)一次性(xing)電(dian)池(chi)(chi)。除了干電(dian)池(chi)(chi)外，常(chang)見的(de)碳鋅(xin)電(dian)池(chi)(chi)、堿性(xing)電(dian)池(chi)(chi)、水銀電(dian)池(chi)(chi)、鋅(xin)空氣電(dian)池(chi)(chi)等都屬(shu)于(yu)一次電(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(jiu)是指可以通過充電(dian)或其(qi)他方式補充電(dian)能的電(dian)池(chi)，這(zhe)兩種電(dian)池(chi)的區別主要有：

1、二次(ci)電(dian)池(chi)在放電(dian)時電(dian)極體(ti)積和結構之間發生(sheng)可(ke)逆(ni)變(bian)(bian)化，而一次(ci)電(dian)池(chi)內(nei)部(bu)則簡單得多，因(yin)為它不(bu)需要調節這些(xie)可(ke)逆(ni)性變(bian)(bian)化。

2、一次電池的(de)質量(liang)(liang)比(bi)容量(liang)(liang)和體積(ji)比(bi)容量(liang)(liang)均大(da)(da)于普通充電電池，但內阻遠比(bi)二次電池大(da)(da)，因此(ci)負載能力(li)較低(di)。

3、一次電池的自放(fang)電(dian)(dian)(dian)遠(yuan)小(xiao)于二(er)次(ci)(ci)電(dian)(dian)(dian)池。一次(ci)(ci)電(dian)(dian)(dian)池只能放(fang)電(dian)(dian)(dian)一次(ci)(ci)，如，堿性電(dian)(dian)(dian)池和碳(tan)性電(dian)(dian)(dian)池就屬(shu)于此類，二(er)次(ci)(ci)電(dian)(dian)(dian)池可(ke)反復循環使用。

4、一次(ci)電(dian)(dian)池(chi)內阻遠(yuan)大(da)二(er)次(ci)電(dian)(dian)池(chi)，其大(da)電(dian)(dian)流(liu)放電(dian)(dian)性能亦不及二(er)次(ci)電(dian)(dian)池(chi)，在小(xiao)電(dian)(dian)流(liu)、間歇性放電(dian)(dian)的條件下，一次(ci)電(dian)(dian)池(chi)的質量(liang)比容量(liang)大(da)于(yu)普通二(er)次(ci)電(dian)(dian)池(chi)，但當放電(dian)(dian)電(dian)(dian)流(liu)大(da)于(yu)800mAh，則一次(ci)電(dian)(dian)池(chi)的容量(liang)優勢就(jiu)會明顯減小(xiao)。

5、二次電(dian)(dian)(dian)池(chi)(chi)相對(dui)一(yi)次電(dian)(dian)(dian)池(chi)(chi)更環保。一(yi)次電(dian)(dian)(dian)池(chi)(chi)使(shi)用(yong)(yong)后就(jiu)(jiu)必(bi)須廢(fei)棄，而充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)可反復(fu)(fu)使(shi)用(yong)(yong)，符合(he)國(guo)家標準(zhun)的(de)(de)次世代充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)通常(chang)可反復(fu)(fu)使(shi)用(yong)(yong)1000次以上，也就(jiu)(jiu)是(shi)說(shuo)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)(chi)產生的(de)(de)廢(fei)棄物不到(dao)一(yi)次電(dian)(dian)(dian)池(chi)(chi)的(de)(de)1000分之1，不論從減少廢(fei)棄物還是(shi)從資源利(li)用(yong)(yong)及經濟的(de)(de)角(jiao)度來(lai)考慮，二次電(dian)(dian)(dian)池(chi)(chi)的(de)(de)優越性(xing)都是(shi)十(shi)分明(ming)顯的(de)(de)。
