一、一次電池是什么意思
一次電池,也叫一次性電池,是指放電結束后不能再通過充電使其復原(yuan),再度使用的電池,這種(zhong)電池通常只能一次性使用,無法通過充電或其它方(fang)式將原(yuan)有(you)電能補充回來。
一(yi)(yi)次電池一(yi)(yi)般用完(wan)即廢,這一(yi)(yi)特性是(shi)它的(de)(de)電池反應或(huo)電極反應的(de)(de)不可(ke)逆性或(huo)條件,限制使電池反應很難可(ke)逆地進行(xing)所決定的(de)(de)。
二、干電池是一次性電池嗎
是的。
干(gan)電(dian)(dian)池(chi)(chi)(chi)的原理是利(li)用氧化(hua)還原反應將化(hua)學能(neng)轉化(hua)為(wei)電(dian)(dian)能(neng),這一化(hua)學反應是不可逆的,不能(neng)進行(xing)充電(dian)(dian)和放電(dian)(dian)循環使用,因此屬(shu)于一次(ci)性電(dian)(dian)池(chi)(chi)(chi)。除(chu)了干(gan)電(dian)(dian)池(chi)(chi)(chi)外,常(chang)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)、鋅空氣電(dian)(dian)池(chi)(chi)(chi)等都屬(shu)于一次(ci)電(dian)(dian)池(chi)(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)就是指可(ke)以通過充(chong)電(dian)或其(qi)他方(fang)式補(bu)充(chong)電(dian)能的電(dian)池(chi),這兩(liang)種(zhong)電(dian)池(chi)的區別主要(yao)有:
1、二次電(dian)池在放電(dian)時電(dian)極(ji)體積(ji)和(he)結構(gou)之間發(fa)生(sheng)可(ke)逆變(bian)化,而一次電(dian)池內部則簡單得多,因為它不需(xu)要(yao)調節這些可(ke)逆性變(bian)化。
2、一次(ci)(ci)電池的質量比容(rong)(rong)量和體(ti)積比容(rong)(rong)量均大(da)于普通充電電池,但內阻(zu)遠(yuan)比二次(ci)(ci)電池大(da),因此(ci)負(fu)載能力較低。
3、一次電池的自放電遠小于二次(ci)電池。一次(ci)電池只(zhi)能放電一次(ci),如,堿性(xing)電池和碳性(xing)電池就屬于此類,二次(ci)電池可反復循環(huan)使用(yong)。
4、一次(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)內阻遠大(da)二次(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi),其大(da)電(dian)(dian)(dian)(dian)流放(fang)電(dian)(dian)(dian)(dian)性能亦(yi)不及二次(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi),在(zai)小電(dian)(dian)(dian)(dian)流、間歇(xie)性放(fang)電(dian)(dian)(dian)(dian)的(de)(de)條件下,一次(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)質(zhi)量(liang)比容(rong)量(liang)大(da)于(yu)普通(tong)二次(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi),但當放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)流大(da)于(yu)800mAh,則一次(ci)(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)容(rong)量(liang)優勢(shi)就會明顯減小。
5、二次(ci)電(dian)(dian)(dian)池(chi)相對一(yi)次(ci)電(dian)(dian)(dian)池(chi)更(geng)環保。一(yi)次(ci)電(dian)(dian)(dian)池(chi)使用(yong)(yong)后就(jiu)必須廢(fei)棄,而(er)充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)可反復使用(yong)(yong),符合國家標(biao)準的(de)(de)(de)次(ci)世(shi)代充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)通常可反復使用(yong)(yong)1000次(ci)以上,也就(jiu)是說充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)池(chi)產生(sheng)的(de)(de)(de)廢(fei)棄物不(bu)到一(yi)次(ci)電(dian)(dian)(dian)池(chi)的(de)(de)(de)1000分(fen)(fen)之(zhi)1,不(bu)論從(cong)減少廢(fei)棄物還(huan)是從(cong)資源利用(yong)(yong)及經濟(ji)的(de)(de)(de)角度來考慮,二次(ci)電(dian)(dian)(dian)池(chi)的(de)(de)(de)優(you)越性都是十(shi)分(fen)(fen)明(ming)顯的(de)(de)(de)。
