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(hou)不能再通過充(chong)電(dian)(dian)使其(qi)復原，再度(du)使用的(de)電(dian)(dian)池(chi)，這種電(dian)(dian)池(chi)通常(chang)只能一次性使用，無法通過充(chong)電(dian)(dian)或其(qi)它方式將原有(you)電(dian)(dian)能補充(chong)回來(lai)。

一(yi)次(ci)電池一(yi)般用完即廢，這一(yi)特性(xing)是(shi)它的(de)電池反(fan)應或電極反(fan)應的(de)不(bu)可(ke)逆性(xing)或條(tiao)件，限制(zhi)使電池反(fan)應很難可(ke)逆地進(jin)行(xing)所決定的(de)。

二、干電池是一次性電池嗎

是的。

干電(dian)(dian)池(chi)(chi)(chi)的原理是(shi)利(li)用氧化還原反應將化學能(neng)轉化為電(dian)(dian)能(neng)，這一(yi)化學反應是(shi)不可逆的，不能(neng)進行充電(dian)(dian)和放電(dian)(dian)循環使用，因此屬于一(yi)次性電(dian)(dian)池(chi)(chi)(chi)。除了干電(dian)(dian)池(chi)(chi)(chi)外，常見的碳鋅電(dian)(dian)池(chi)(chi)(chi)、堿性電(dian)(dian)池(chi)(chi)(chi)、水銀電(dian)(dian)池(chi)(chi)(chi)、鋅空(kong)氣(qi)電(dian)(dian)池(chi)(chi)(chi)等都屬于一(yi)次電(dian)(dian)池(chi)(chi)(chi)。

三、一次電池和二次電池的區別

和一次電(dian)(dian)池相對的(de)，二次電(dian)(dian)池就是(shi)指可以通過充電(dian)(dian)或其他方式補充電(dian)(dian)能的(de)電(dian)(dian)池，這兩(liang)種電(dian)(dian)池的(de)區別主要有：

1、二次(ci)(ci)電池在放電時電極(ji)體積和(he)結構之(zhi)間(jian)發(fa)生(sheng)可逆變(bian)化，而一次(ci)(ci)電池內部則簡(jian)單得(de)多，因為它不需要調節這些可逆性(xing)變(bian)化。

2、一次電池的質(zhi)量(liang)比(bi)容量(liang)和體(ti)積比(bi)容量(liang)均大于普(pu)通充(chong)電電池，但內阻遠比(bi)二次電池大，因此(ci)負載能力較低。

3、一次電池的(de)自(zi)放電(dian)(dian)遠小于(yu)二次電(dian)(dian)池。一(yi)次電(dian)(dian)池只能放電(dian)(dian)一(yi)次，如，堿(jian)性電(dian)(dian)池和碳性電(dian)(dian)池就屬于(yu)此類，二次電(dian)(dian)池可(ke)反復循(xun)環(huan)使(shi)用。

4、一(yi)次(ci)電(dian)(dian)(dian)(dian)(dian)池(chi)內阻遠(yuan)大二次(ci)電(dian)(dian)(dian)(dian)(dian)池(chi)，其大電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)放電(dian)(dian)(dian)(dian)(dian)性能亦(yi)不及二次(ci)電(dian)(dian)(dian)(dian)(dian)池(chi)，在(zai)小(xiao)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)、間(jian)歇性放電(dian)(dian)(dian)(dian)(dian)的條(tiao)件下，一(yi)次(ci)電(dian)(dian)(dian)(dian)(dian)池(chi)的質量比(bi)容(rong)(rong)量大于(yu)普通二次(ci)電(dian)(dian)(dian)(dian)(dian)池(chi)，但當放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)大于(yu)800mAh，則一(yi)次(ci)電(dian)(dian)(dian)(dian)(dian)池(chi)的容(rong)(rong)量優勢就(jiu)會(hui)明顯減小(xiao)。

5、二次(ci)電池(chi)相對一次(ci)電池(chi)更環保(bao)。一次(ci)電池(chi)使(shi)用(yong)(yong)后(hou)就(jiu)必須(xu)廢棄(qi)，而充電電池(chi)可(ke)反(fan)復使(shi)用(yong)(yong)，符合國家標準的次(ci)世代充電電池(chi)通常可(ke)反(fan)復使(shi)用(yong)(yong)1000次(ci)以上，也就(jiu)是(shi)說(shuo)充電電池(chi)產生的廢棄(qi)物不到一次(ci)電池(chi)的1000分之1，不論從減少廢棄(qi)物還是(shi)從資源利用(yong)(yong)及經濟的角度(du)來考慮，二次(ci)電池(chi)的優越性都(dou)是(shi)十分明(ming)顯(xian)的。
