一、紐扣電池和普通電池的區別

紐扣電池與普通電池之(zhi)間，有(you)外形大小，化(hua)學成(cheng)分，內部電壓產生方式，材質(zhi)等(deng)的區別(bie)。

紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)也(ye)(ye)稱扣(kou)式電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，是指外形尺寸(cun)象一(yi)(yi)顆(ke)小紐(niu)扣(kou)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，一(yi)(yi)般(ban)(ban)來說(shuo)直徑(jing)較(jiao)(jiao)(jiao)(jiao)大(da)，厚度較(jiao)(jiao)(jiao)(jiao)薄。它的(de)(de)(de)外形猶如(ru)一(yi)(yi)顆(ke)紐(niu)扣(kou)，所以也(ye)(ye)被稱為紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。常(chang)見的(de)(de)(de)紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)按化(hua)學組(zu)成有(you)(you)碳性，堿性，鋅(xin)一(yi)(yi)氧化(hua)銀，鋅(xin)一(yi)(yi)空(kong)氣，鋰一(yi)(yi)二氧化(hua)錳，鎳鎘充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，鎳氫(qing)充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)等。紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)相(xiang)對其他普(pu)通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，使用(yong)(yong)壽(shou)命較(jiao)(jiao)(jiao)(jiao)長(chang)。紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)一(yi)(yi)般(ban)(ban)裝配在設(she)備上面，規廠家生產(chan)的(de)(de)(de)紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)一(yi)(yi)般(ban)(ban)較(jiao)(jiao)(jiao)(jiao)長(chang)時間都不需要進行更換，這(zhe)類電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)通常(chang)處于設(she)備的(de)(de)(de)內(nei)部，很(hen)少與(yu)外界進行直接的(de)(de)(de)接觸，因此(ci)它能得到(dao)很(hen)好的(de)(de)(de)防護，使用(yong)(yong)壽(shou)命也(ye)(ye)比較(jiao)(jiao)(jiao)(jiao)長(chang)。紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)主要的(de)(de)(de)用(yong)(yong)途(tu)是：計算器(qi)，助聽器(qi)，相(xiang)機，手表等小型物件上。紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)也(ye)(ye)比較(jiao)(jiao)(jiao)(jiao)平穩(wen)(wen)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)平穩(wen)(wen)是指在持(chi)續(xu)輸出(chu)的(de)(de)(de)過程中(zhong)呈現出(chu)平穩(wen)(wen)的(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)狀(zhuang)態，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流穩(wen)(wen)定，因此(ci)紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)常(chang)常(chang)被用(yong)(yong)于精密(mi)儀器(qi)中(zhong)。紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)觸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容量也(ye)(ye)比較(jiao)(jiao)(jiao)(jiao)大(da)，紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)看似體(ti)積較(jiao)(jiao)(jiao)(jiao)小，實則它在有(you)(you)限的(de)(de)(de)空(kong)間儲(chu)存了大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，能維(wei)持(chi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設(she)備長(chang)時間持(chi)續(xu)運轉，紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)使用(yong)(yong)范(fan)圍也(ye)(ye)非(fei)常(chang)的(de)(de)(de)廣。

二、紐扣電池可以充電嗎

固有印象中，紐扣電池都是一次性(xing)(xing)的，沒電(dian)(dian)(dian)(dian)(dian)(dian)了(le)(le)就要更換新電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。例如汽車遙控鑰匙上(shang)的電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，以(yi)及電(dian)(dian)(dian)(dian)(dian)(dian)腦(nao)主板(ban)BIOS芯(xin)片的電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，總(zong)要定(ding)期更換，否則就會(hui)失(shi)靈、失(shi)常(chang)。不過(guo)技術總(zong)在進步，近些年來市場上(shang)出現(xian)了(le)(le)一大(da)批可(ke)以(yi)充電(dian)(dian)(dian)(dian)(dian)(dian)的紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，有些廠商不僅能(neng)夠提供性(xing)(xing)能(neng)穩(wen)定(ding)的可(ke)充電(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，甚至(zhi)還提供了(le)(le)穩(wen)定(ding)、可(ke)靠的充電(dian)(dian)(dian)(dian)(dian)(dian)解決方案(an)。據我了(le)(le)解，目前比較多見(jian)的可(ke)充電(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)主要有ML（鋰(li)錳電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）、LIR（鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）、NI-MH（鎳(nie)氫電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）和NI-Cd（鎳(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）四(si)種(zhong)類(lei)型，這(zhe)四(si)種(zhong)紐(niu)扣(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的尺寸、放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓、充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓、容(rong)量、安全(quan)特(te)性(xing)(xing)以(yi)及市場價格(ge)的信息(xi)如下。

1、ML可充紐(niu)扣電(dian)(dian)(dian)(dian)(dian)池類型：鋰(li)錳電(dian)(dian)(dian)(dian)(dian)池放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)：3V充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)：3V左(zuo)右(you)(you)(you)容量(liang)：1220型電(dian)(dian)(dian)(dian)(dian)池的容量(liang)多在(zai)10mAh左(zuo)右(you)(you)(you)。安全(quan)特性(xing)：安全(quan)性(xing)和(he)環保性(xing)等(deng)同于(yu)鋰(li)電(dian)(dian)(dian)(dian)(dian)池市場價(jia)格及應用(yong)領(ling)域：廣泛應用(yong)于(yu)攝(she)像(xiang)頭、筆(bi)記本電(dian)(dian)(dian)(dian)(dian)腦、計(ji)算機、傳感器和(he)小型醫(yi)療設備中(zhong)；1220型單顆售價(jia)多在(zai)10元左(zuo)右(you)(you)(you)。

2、LIR可充(chong)紐(niu)扣電(dian)(dian)池類型：鋰電(dian)(dian)池放電(dian)(dian)電(dian)(dian)壓：3.7V充(chong)電(dian)(dian)電(dian)(dian)壓：5V容量：1220型電(dian)(dian)池的(de)容量多在8mAh左(zuo)右。安(an)全(quan)特性：比較(jiao)安(an)全(quan)；無重金(jin)屬，比較(jiao)環保(bao)。市場價格及應(ying)(ying)用領域(yu)：廣泛(fan)應(ying)(ying)用于使用3.7V鋰電(dian)(dian)池供(gong)電(dian)(dian)的(de)小(xiao)型設(she)備(bei)(bei)和智能設(she)備(bei)(bei)，1220型單(dan)顆售價只有3元左(zuo)右（價格便宜）。

3、NI-MH可(ke)(ke)充(chong)紐扣(kou)電(dian)(dian)池類型：鎳氫電(dian)(dian)池放電(dian)(dian)電(dian)(dian)壓(ya)：1.2V（單顆）充(chong)電(dian)(dian)電(dian)(dian)壓(ya)：1.2V左右(you)(you)容(rong)量：1220型電(dian)(dian)池的容(rong)量多在15mAh左右(you)(you)。安全特(te)性：比較安全；無重金屬(shu)，比較環保。市場價格(ge)(ge)及應(ying)用領域：主要被(bei)生產廠(chang)家應(ying)用于電(dian)(dian)熱水器(qi)、電(dian)(dian)飯煲(bao)、定時器(qi)、電(dian)(dian)動(dong)玩具(ju)、汽(qi)車音響(xiang)、便攜式錄音筆(bi)、稅控(kong)加油機(ji)、收銀機(ji)等設備，一組三粒串聯、容(rong)量40mAh的非標準尺(chi)寸NI-MH可(ke)(ke)充(chong)紐扣(kou)電(dian)(dian)池售價只有(you)6元左右(you)(you)，價格(ge)(ge)非常便宜。

4、NI-Cd可充紐扣(kou)電(dian)(dian)池(chi)類型：鎳(nie)(nie)鎘電(dian)(dian)池(chi)放電(dian)(dian)電(dian)(dian)壓(ya)、充電(dian)(dian)電(dian)(dian)壓(ya)、容(rong)量(liang)等(deng)方面均與NI-MH（鎳(nie)(nie)氫）電(dian)(dian)池(chi)相近，但由于鎘是一(yi)種重(zhong)金(jin)屬，如果回收不當可能會對(dui)環境造成污染。正是由于其不環保的(de)特性，目前的(de)應用越(yue)來越(yue)少（價格倒是非常便宜）。
