一、紐扣電池和普通電池的區別

紐扣電池與普通(tong)電(dian)池之(zhi)間，有外形大小，化(hua)學成分，內部電(dian)壓產生方式，材質(zhi)等的區別(bie)。

紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)也(ye)稱扣(kou)(kou)(kou)式(shi)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，是指(zhi)(zhi)外形尺寸(cun)象一(yi)(yi)顆小紐(niu)(niu)扣(kou)(kou)(kou)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，一(yi)(yi)般(ban)來說直徑(jing)較大(da)，厚度較薄(bo)。它(ta)的(de)(de)(de)(de)外形猶如一(yi)(yi)顆紐(niu)(niu)扣(kou)(kou)(kou)，所以也(ye)被稱為紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。常(chang)(chang)見的(de)(de)(de)(de)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)按化學組成有碳(tan)性，堿性，鋅一(yi)(yi)氧(yang)化銀，鋅一(yi)(yi)空氣，鋰一(yi)(yi)二氧(yang)化錳，鎳鎘充(chong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)(niu)扣(kou)(kou)(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)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)等(deng)。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)相(xiang)對其(qi)他(ta)普通(tong)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，使用(yong)壽命(ming)較長(chang)(chang)。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)一(yi)(yi)般(ban)裝配(pei)在(zai)設(she)備上面，規廠家生(sheng)產(chan)的(de)(de)(de)(de)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)一(yi)(yi)般(ban)較長(chang)(chang)時間都不需要進(jin)行更換，這類電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)通(tong)常(chang)(chang)處于(yu)設(she)備的(de)(de)(de)(de)內部，很(hen)少與外界(jie)進(jin)行直接的(de)(de)(de)(de)接觸，因(yin)此它(ta)能(neng)得(de)到很(hen)好的(de)(de)(de)(de)防護，使用(yong)壽命(ming)也(ye)比(bi)較長(chang)(chang)。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)主(zhu)要的(de)(de)(de)(de)用(yong)途是：計(ji)算器，助聽器，相(xiang)機，手表等(deng)小型物(wu)件上。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓也(ye)比(bi)較平(ping)穩(wen)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓平(ping)穩(wen)是指(zhi)(zhi)在(zai)持續(xu)輸出(chu)的(de)(de)(de)(de)過程中呈現出(chu)平(ping)穩(wen)的(de)(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓狀態，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流穩(wen)定，因(yin)此紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)常(chang)(chang)常(chang)(chang)被用(yong)于(yu)精密(mi)儀器中。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)(de)觸電(dian)(dian)(dian)(dian)(dian)(dian)(dian)容(rong)量也(ye)比(bi)較大(da)，紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)看(kan)似體積(ji)較小，實則它(ta)在(zai)有限的(de)(de)(de)(de)空間儲存了(le)大(da)量的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)流，能(neng)維持電(dian)(dian)(dian)(dian)(dian)(dian)(dian)子設(she)備長(chang)(chang)時間持續(xu)運(yun)轉，紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)使用(yong)范圍也(ye)非常(chang)(chang)的(de)(de)(de)(de)廣(guang)。

普通電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)也(ye)(ye)就(jiu)是(shi)(shi)常(chang)用的(de)(de)(de)(de)(de)干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，比如(ru)7號電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。7號電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)也(ye)(ye)被稱作(zuo)AAA電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，是(shi)(shi)一種(zhong)(zhong)常(chang)見的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)呈圓柱(zhu)形(xing)，高43.6毫(hao)米，直(zhi)(zhi)徑(jing)10.1毫(hao)米。常(chang)用于(yu)體積較小，耗電(dian)(dian)(dian)(dian)(dian)量不太(tai)高的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)子產品。既有一次(ci)性的(de)(de)(de)(de)(de)堿(jian)(jian)性電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，也(ye)(ye)有可(ke)充(chong)電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)鎳氫、鋰(li)離子電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。常(chang)見的(de)(de)(de)(de)(de)干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)為鋅錳(meng)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，也(ye)(ye)被稱為碳(tan)(tan)鋅電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、堿(jian)(jian)性電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)、鎳鎘電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)與鋰(li)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)等。這種(zhong)(zhong)干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)一種(zhong)(zhong)以糊狀電(dian)(dian)(dian)(dian)(dian)解液來產生(sheng)直(zhi)(zhi)流電(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)(de)化學(xue).電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，屬于(yu)一次(ci)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，是(shi)(shi)日(ri)常(chang)生(sheng)活之中為普遍(bian)使用，以及輕便的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。普通干(gan)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)大都是(shi)(shi)錳(meng)鋅電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是(shi)(shi)由碳(tan)(tan)棒(bang)和(he)鋅桶做正負極(ji)，中間(jian)是(shi)(shi)正極(ji)碳(tan)(tan)棒(bang)，外包(bao)石墨和(he)二氧化錳(meng)的(de)(de)(de)(de)(de)混合物，再外一層(ceng)是(shi)(shi)一層(ceng)纖維網。網上(shang)涂有很厚(hou)的(de)(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)解質(zhi)糊，其構成是(shi)(shi)氯化氨溶液和(he)淀粉，還加有少量防腐劑(ji)。

二、紐扣電池可以充電嗎

固有印象中，紐扣電池都(dou)是(shi)一(yi)次(ci)性(xing)的(de)(de)(de)(de)，沒電(dian)了就要更換(huan)(huan)新電(dian)池(chi)(chi)(chi)。例(li)如汽車遙(yao)控鑰匙上的(de)(de)(de)(de)電(dian)池(chi)(chi)(chi)，以(yi)及電(dian)腦主板(ban)BIOS芯片的(de)(de)(de)(de)電(dian)池(chi)(chi)(chi)，總要定(ding)期更換(huan)(huan)，否則就會失靈、失常(chang)。不(bu)過技術總在(zai)進(jin)步(bu)，近些年(nian)來市場(chang)上出(chu)現了一(yi)大批(pi)可以(yi)充(chong)電(dian)的(de)(de)(de)(de)紐扣(kou)電(dian)池(chi)(chi)(chi)，有(you)些廠商不(bu)僅能(neng)夠(gou)提(ti)供性(xing)能(neng)穩定(ding)的(de)(de)(de)(de)可充(chong)電(dian)紐扣(kou)電(dian)池(chi)(chi)(chi)，甚至(zhi)還提(ti)供了穩定(ding)、可靠的(de)(de)(de)(de)充(chong)電(dian)解決方案(an)。據我了解，目前比較多見的(de)(de)(de)(de)可充(chong)電(dian)紐扣(kou)電(dian)池(chi)(chi)(chi)主要有(you)ML（鋰錳電(dian)池(chi)(chi)(chi)）、LIR（鋰電(dian)池(chi)(chi)(chi)）、NI-MH（鎳(nie)氫電(dian)池(chi)(chi)(chi)）和NI-Cd（鎳(nie)鎘電(dian)池(chi)(chi)(chi)）四(si)種類型(xing)，這四(si)種紐扣(kou)電(dian)池(chi)(chi)(chi)的(de)(de)(de)(de)尺寸、放電(dian)電(dian)壓(ya)、充(chong)電(dian)電(dian)壓(ya)、容量(liang)、安全特性(xing)以(yi)及市場(chang)價格(ge)的(de)(de)(de)(de)信息如下。

1、ML可充(chong)(chong)紐扣電(dian)(dian)(dian)池(chi)(chi)類型：鋰錳電(dian)(dian)(dian)池(chi)(chi)放電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)：3V充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)：3V左(zuo)右(you)容量(liang)：1220型電(dian)(dian)(dian)池(chi)(chi)的容量(liang)多(duo)在10mAh左(zuo)右(you)。安全(quan)特(te)性：安全(quan)性和(he)環保性等同于(yu)鋰電(dian)(dian)(dian)池(chi)(chi)市場價(jia)格及應(ying)用(yong)(yong)領(ling)域：廣泛應(ying)用(yong)(yong)于(yu)攝像頭、筆記本電(dian)(dian)(dian)腦、計(ji)算(suan)機、傳感器和(he)小型醫療設備中(zhong)；1220型單顆售(shou)價(jia)多(duo)在10元左(zuo)右(you)。

2、LIR可充紐扣電(dian)(dian)池類型(xing)：鋰電(dian)(dian)池放電(dian)(dian)電(dian)(dian)壓(ya)：3.7V充電(dian)(dian)電(dian)(dian)壓(ya)：5V容量(liang)：1220型(xing)電(dian)(dian)池的容量(liang)多(duo)在8mAh左右(you)。安全(quan)特性(xing)：比較安全(quan)；無重(zhong)金屬，比較環保(bao)。市場價(jia)格(ge)(ge)及應用領域：廣泛(fan)應用于(yu)使用3.7V鋰電(dian)(dian)池供電(dian)(dian)的小型(xing)設備(bei)和智能設備(bei)，1220型(xing)單顆售價(jia)只有3元左右(you)（價(jia)格(ge)(ge)便(bian)宜）。

3、NI-MH可充(chong)紐扣電池類型(xing)：鎳氫電池放電電壓(ya)：1.2V（單顆）充(chong)電電壓(ya)：1.2V左右容(rong)量(liang)(liang)(liang)：1220型(xing)電池的(de)容(rong)量(liang)(liang)(liang)多在15mAh左右。安(an)全特性(xing)：比較(jiao)安(an)全；無(wu)重(zhong)金屬，比較(jiao)環保。市(shi)場價格及應用領域(yu)：主要(yao)被生產廠家(jia)應用于電熱水(shui)器、電飯煲、定時器、電動玩具(ju)、汽(qi)車音(yin)響、便攜式錄音(yin)筆、稅控加油機(ji)、收銀(yin)機(ji)等設備，一組(zu)三粒串聯、容(rong)量(liang)(liang)(liang)40mAh的(de)非(fei)(fei)標準尺寸NI-MH可充(chong)紐扣電池售價只(zhi)有6元左右，價格非(fei)(fei)常便宜。

4、NI-Cd可充紐扣(kou)電(dian)池類型：鎳鎘電(dian)池放電(dian)電(dian)壓(ya)、充電(dian)電(dian)壓(ya)、容(rong)量等方面均(jun)與NI-MH（鎳氫）電(dian)池相(xiang)近，但由于鎘是(shi)(shi)一種(zhong)重(zhong)金屬(shu)，如果回收不(bu)當可能會對(dui)環(huan)境(jing)造成污(wu)染(ran)。正是(shi)(shi)由于其不(bu)環(huan)保的特性，目前的應用(yong)越來越少（價(jia)格倒是(shi)(shi)非常便宜）。
