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(bu)能(neng)再(zai)通(tong)(tong)過充(chong)電(dian)使其復原，再(zai)度(du)使用的(de)電(dian)池，這種(zhong)電(dian)池通(tong)(tong)常只能(neng)一(yi)次性使用，無法通(tong)(tong)過充(chong)電(dian)或其它方式(shi)將原有電(dian)能(neng)補(bu)充(chong)回來。

一次(ci)電(dian)(dian)池一般用完即廢，這一特(te)性(xing)是它的電(dian)(dian)池反(fan)應(ying)或電(dian)(dian)極反(fan)應(ying)的不(bu)可逆性(xing)或條件，限制使電(dian)(dian)池反(fan)應(ying)很難可逆地進行所(suo)決定的。

二、干電池是一次性電池嗎

是的。

干(gan)電(dian)(dian)(dian)池(chi)的原理是利用氧化還(huan)原反應(ying)將化學能(neng)轉化為(wei)電(dian)(dian)(dian)能(neng)，這(zhe)一(yi)化學反應(ying)是不(bu)可逆的，不(bu)能(neng)進行充電(dian)(dian)(dian)和放(fang)電(dian)(dian)(dian)循環使用，因此(ci)屬(shu)于一(yi)次性電(dian)(dian)(dian)池(chi)。除了干(gan)電(dian)(dian)(dian)池(chi)外(wai)，常見的碳鋅電(dian)(dian)(dian)池(chi)、堿性電(dian)(dian)(dian)池(chi)、水銀電(dian)(dian)(dian)池(chi)、鋅空氣電(dian)(dian)(dian)池(chi)等都(dou)屬(shu)于一(yi)次電(dian)(dian)(dian)池(chi)。

三、一次電池和二次電池的區別

和一次電(dian)池(chi)相對的，二(er)次電(dian)池(chi)就(jiu)是指可(ke)以通過充(chong)電(dian)或其(qi)他方式補充(chong)電(dian)能的電(dian)池(chi)，這兩種電(dian)池(chi)的區別(bie)主(zhu)要有：

1、二(er)次電池在放電時(shi)電極體積和結構之間發生可逆變化，而一次電池內部(bu)則簡單(dan)得多，因為它不需要(yao)調(diao)節這些可逆性變化。

2、一次電池(chi)的質量比(bi)容量和體積比(bi)容量均大于(yu)普通充電電池(chi)，但內阻(zu)遠比(bi)二次電池(chi)大，因此(ci)負載(zai)能力較低。

3、一次電池的自放電遠(yuan)小于二(er)次電池。一(yi)(yi)次電池只能放電一(yi)(yi)次，如，堿性(xing)電池和碳(tan)性(xing)電池就屬于此類，二(er)次電池可(ke)反復循(xun)環使(shi)用。

4、一次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內阻遠大二(er)次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，其大電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)放電(dian)(dian)(dian)(dian)性能(neng)亦不及二(er)次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，在小(xiao)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)、間歇性放電(dian)(dian)(dian)(dian)的條件下(xia)，一次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的質量比(bi)容量大于(yu)普通二(er)次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，但(dan)當放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流(liu)(liu)(liu)大于(yu)800mAh，則(ze)一次(ci)(ci)(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的容量優勢就會(hui)明顯減(jian)小(xiao)。

5、二次(ci)(ci)電(dian)(dian)池(chi)(chi)(chi)相對一次(ci)(ci)電(dian)(dian)池(chi)(chi)(chi)更環保。一次(ci)(ci)電(dian)(dian)池(chi)(chi)(chi)使用(yong)(yong)(yong)后(hou)就(jiu)必須廢棄，而(er)充電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)可反復使用(yong)(yong)(yong)，符合國家標準的次(ci)(ci)世代充電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)通常可反復使用(yong)(yong)(yong)1000次(ci)(ci)以上，也就(jiu)是說充電(dian)(dian)電(dian)(dian)池(chi)(chi)(chi)產生(sheng)的廢棄物(wu)(wu)不(bu)到(dao)一次(ci)(ci)電(dian)(dian)池(chi)(chi)(chi)的1000分(fen)之(zhi)1，不(bu)論(lun)從減少廢棄物(wu)(wu)還(huan)是從資源利(li)用(yong)(yong)(yong)及(ji)經(jing)濟的角度來考慮，二次(ci)(ci)電(dian)(dian)池(chi)(chi)(chi)的優越性都是十分(fen)明(ming)顯的。
