主要常見紐扣電池按化(hua)學組(zu)成大(da)類(lei)來分的話有鋅(xin)-氧化(hua)銀紐(niu)(niu)扣(kou)電(dian)池(chi)，鎳(nie)氫（Ni-MH）二(er)次充電(dian)紐(niu)(niu)扣(kou)電(dian)池(chi)，紐(niu)(niu)扣(kou)鋰電(dian)池(chi)，鋅(xin)-空(kong)氣(qi)紐(niu)(niu)扣(kou)電(dian)池(chi)等(deng)這(zhe)幾種(zhong)，詳(xiang)細的來說(shuo)碳性紐(niu)(niu)扣(kou)電(dian)池(chi)最常見，也(ye)最便宜，堿(jian)性的貴一點，但是放電(dian)效(xiao)果好。這(zhe)兩種(zhong)電(dian)壓都(dou)是1.5V從堿(jian)性AG1到AG13，標稱容(rong)量大(da)約(yue)從15mAh到140mAh不等(deng)。

1、鋅-氧化銀(yin)紐(niu)(niu)扣(kou)電池(chi)，算是(shi)紐(niu)(niu)扣(kou)電池(chi)中的佼(jiao)(jiao)佼(jiao)(jiao)者了(le)。電壓(ya)1.55V，容量高于碳性，堿性紐(niu)(niu)扣(kou)電池(chi)，高階放(fang)電曲(qu)線(xian)平穩(wen)，大(da)約(yue)有90%的部分(fen)始終穩(wen)定(ding)在1.45V以上，放(fang)電曲(qu)線(xian)幾(ji)乎成一條(tiao)直線(xian)，然(ran)后迅速掉電，電壓(ya)豎直掉下去。主要的用途是(shi)：計算器(qi)，助聽器(qi)，相機，手表等(deng)。特別(bie)指出一點，這種電池(chi)的防漏液效(xiao)果特別(bie)好(hao)，而且長效(xiao)使用效(xiao)果也(ye)不錯。

2、鎳氫（Ni-MH）二次充(chong)電(dian)紐扣電(dian)池通常(chang)(chang)都是(shi)組(zu)合成電(dian)池組(zu)使用(yong)(yong)，單(dan)體電(dian)池供電(dian)使用(yong)(yong)的(de)情況比較少(shao)。一般常(chang)(chang)見的(de)鎳氫鎳鎘(ge)紐扣電(dian)池型(xing)號差不多都是(shi)那幾種（軍工產品除外）。

3、紐扣鋰電池

這個(ge)會有一次性使(shi)用(yong)不可充電(dian)(dian)電(dian)(dian)池和可充電(dian)(dian)重復使(shi)用(yong)電(dian)(dian)池兩大(da)類。

（1）鋰(li)-二(er)(er)氧化錳(meng)一(yi)(yi)次性紐(niu)(niu)扣電池（CR紐(niu)(niu)扣電池系列）。鋰(li)錳(meng)一(yi)(yi)次性紐(niu)(niu)扣電池標稱電壓是3V，終(zhong)止(zhi)電壓2V，典型工(gong)(gong)作電流(liu)在0.1-0.2mA。它采用化學(xue)性質非常穩定的二(er)(er)氧化錳(meng)為正極材(cai)(cai)料，以比能量非常高(gao)的鋰(li)金(jin)屬為負極材(cai)(cai)料。年平均容量降(jiang)低不大于(yu)2%，儲存壽命長(chang)。電池采用半密封結(jie)構(gou)，使用安全。鋰(li)錳(meng)一(yi)(yi)次性紐(niu)(niu)扣電池的溫度(du)適應范(fan)圍較大在-20到+60攝氏度(du)的條件下都(dou)可(ke)正常工(gong)(gong)作。用處多在電子詞(ci)典，主板CMOS電池，手表等等。簡要說說鋰(li)錳(meng)紐(niu)(niu)扣電池型號(hao)表示(shi)什么，CR表示(shi)鋰(li)-二(er)(er)氧化錳(meng)，CR后(hou)面(mian)的4位(wei)數字，前兩位(wei)是直徑，后(hou)兩位(wei)是高(gao)，例如(ru)：CR2032是指一(yi)(yi)種20mm直徑，3.2mm高(gao)的鋰(li)-二(er)(er)氧化錳(meng)一(yi)(yi)次性紐(niu)(niu)扣電池。

以(yi)此類推CR1220是指(zhi)一(yi)(yi)種12mm直徑，2.0mm高的鋰-二(er)氧化錳一(yi)(yi)次性紐(niu)扣電(dian)(dian)池。鋰錳一(yi)(yi)次性紐(niu)扣電(dian)(dian)池不(bu)可以(yi)充電(dian)(dian)，也不(bu)能短路，不(bu)可加熱，在庫存(cun)和遺(yi)棄(qi)時要注意電(dian)(dian)池應(ying)該(gai)絕緣，如(ru)果(guo)電(dian)(dian)池與其他物體接觸，搞不(bu)好(hao)會(hui)爆(bao)炸(zha)，或(huo)者(zhe)失效。

（2）二次可充鋰紐扣電池，由于用處少，不常見。但是由于現在電子產品技術應用的不斷提高和鋰電池生產制造水平的不斷提升，現在可充電紐扣鋰電池開始更多的(de)應用(yong)(yong)(yong)在(zai)一些使用(yong)(yong)(yong)頻繁，使用(yong)(yong)(yong)壽命長的(de)電子(zi)產品(pin)中(zhong)，比如現在(zai)很多無線耳(er)機電池使用(yong)(yong)(yong)的(de)就是紐扣鋰電池。

現在使用的藍牙耳機電池主要規格是LIR1254紐扣電池和LIR1054紐扣電(dian)池(chi)(chi)這(zhe)兩個，其(qi)標(biao)稱電(dian)壓(ya)可以達到(dao)3.85V，容量63mAh至76mAh，而(er)且支持(chi)3到(dao)5C倍率快充性能，可以很(hen)好的(de)(de)符合當(dang)前耳機電(dian)池(chi)(chi)的(de)(de)需求，這(zhe)是其(qi)它(ta)類型紐扣電(dian)池(chi)(chi)比不了的(de)(de)優勢，而(er)且其(qi)可以實現高達20C倍率的(de)(de)大電(dian)流放(fang)電(dian)，可以滿足(zu)一些(xie)特殊電(dian)子產(chan)品設(she)備的(de)(de)應用需求。

4、鋅-空氣(qi)紐扣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)比較特殊，在(zai)(zai)我看來他唯(wei)一的(de)(de)民用(yong)(yong)(yong)市場，就(jiu)是高(gao)(gao)檔的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子耳蝸，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子助(zhu)聽器。這(zhe)種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是以金屬鋅為(wei)負(fu)極(ji)(ji)，空氣(qi)中(zhong)氧為(wei)正(zheng)極(ji)(ji)去極(ji)(ji)劑的(de)(de)一次電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，由于(yu)其正(zheng)極(ji)(ji)活(huo)性材(cai)料(liao)儲存于(yu)大氣(qi)中(zhong)，取之(zhi)不盡，用(yong)(yong)(yong)之(zhi)不竭，故該種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)突出特點(dian)是比能量高(gao)(gao)，為(wei)化學電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源中(zhong)各(ge)系(xi)列之(zhi)首。此(ci)外，還(huan)有(you)節能、節材(cai)、對環(huan)境(jing)和生態無(wu)公(gong)害等(deng)優(you)點(dian)，鋅空氣(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓為(wei)1.4V，而(er)且在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)底(di)部(bu)有(you)進氣(qi)孔，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)底(di)部(bu)進氣(qi)孔出廠時(shi)已用(yong)(yong)(yong)膠(jiao)紙粘上，此(ci)時(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)內無(wu)氧氣(qi)，處(chu)于(yu)休眠狀(zhuang)態，撕去膠(jiao)紙后5-30分鐘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)被空氣(qi)逐漸激活(huo)。鋅空氣(qi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)以空氣(qi)中(zhong)氧氣(qi)為(wei)正(zheng)極(ji)(ji)材(cai)料(liao),所以就(jiu)不必再在(zai)(zai)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)內放(fang)入，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)內就(jiu)有(you)空間裝更多的(de)(de)負(fu)極(ji)(ji)材(cai)料(liao)。因(yin)此(ci)，它的(de)(de)容量比其它電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)高(gao)(gao)3-10倍，是所有(you)實用(yong)(yong)(yong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)體系(xi)中(zhong)最高(gao)(gao)的(de)(de)。這(zhe)種電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)還(huan)具有(you)工(gong)作電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓很(hen)平穩，雜音很(hen)小等(deng)優(you)點(dian)，是耳背式，耳內式和耳道式高(gao)(gao)級助(zhu)聽器的(de)(de)最佳電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)源。
