一、紐扣電池和普通電池的區別

紐扣電池與普通(tong)電池之(zhi)間，有外形大小(xiao)，化學(xue)成分，內部電壓產(chan)生方(fang)式(shi)，材質等的(de)區別。

紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)也(ye)稱扣(kou)(kou)式電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，是指(zhi)外(wai)形(xing)尺寸象一顆小(xiao)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，一般來(lai)說直(zhi)徑較(jiao)大(da)，厚(hou)度較(jiao)薄。它(ta)(ta)的(de)(de)(de)外(wai)形(xing)猶如一顆紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)，所以也(ye)被稱為紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)。常(chang)見的(de)(de)(de)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)按化學組(zu)成有(you)碳性，堿性，鋅一氧(yang)化銀，鋅一空氣，鋰(li)一二氧(yang)化錳，鎳(nie)鎘(ge)充(chong)電(dian)(dian)(dian)(dian)(dian)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，鎳(nie)氫充(chong)電(dian)(dian)(dian)(dian)(dian)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)等(deng)。紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)相對(dui)其他普通電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，使用(yong)壽命較(jiao)長(chang)。紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)一般裝配在(zai)設(she)備上面，規(gui)廠家生產的(de)(de)(de)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)一般較(jiao)長(chang)時間都不需(xu)要進(jin)(jin)行更(geng)換，這類電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)通常(chang)處于設(she)備的(de)(de)(de)內部，很少與(yu)外(wai)界進(jin)(jin)行直(zhi)接的(de)(de)(de)接觸，因此(ci)它(ta)(ta)能(neng)得(de)到很好的(de)(de)(de)防護，使用(yong)壽命也(ye)比(bi)(bi)較(jiao)長(chang)。紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)主(zhu)要的(de)(de)(de)用(yong)途(tu)是：計算器，助聽器，相機，手表等(deng)小(xiao)型物件上。紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓(ya)也(ye)比(bi)(bi)較(jiao)平(ping)穩，電(dian)(dian)(dian)(dian)(dian)壓(ya)平(ping)穩是指(zhi)在(zai)持(chi)續(xu)輸(shu)出的(de)(de)(de)過程(cheng)中(zhong)呈現出平(ping)穩的(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)狀態，電(dian)(dian)(dian)(dian)(dian)流穩定，因此(ci)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)常(chang)常(chang)被用(yong)于精密儀器中(zhong)。紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)的(de)(de)(de)觸電(dian)(dian)(dian)(dian)(dian)容量也(ye)比(bi)(bi)較(jiao)大(da)，紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)看似(si)體積較(jiao)小(xiao)，實(shi)則它(ta)(ta)在(zai)有(you)限(xian)的(de)(de)(de)空間儲(chu)存(cun)了大(da)量的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流，能(neng)維持(chi)電(dian)(dian)(dian)(dian)(dian)子設(she)備長(chang)時間持(chi)續(xu)運轉，紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)使用(yong)范圍(wei)也(ye)非常(chang)的(de)(de)(de)廣。

普通電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)也(ye)就(jiu)是(shi)常(chang)用的(de)(de)(de)干(gan)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，比如(ru)7號電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。7號電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)也(ye)被(bei)(bei)稱作AAA電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，是(shi)一(yi)(yi)種常(chang)見的(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)呈圓(yuan)柱形，高(gao)43.6毫米，直(zhi)徑10.1毫米。常(chang)用于體積較小，耗電(dian)(dian)(dian)量不太高(gao)的(de)(de)(de)電(dian)(dian)(dian)子產品。既有一(yi)(yi)次性(xing)(xing)的(de)(de)(de)堿(jian)性(xing)(xing)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，也(ye)有可(ke)充電(dian)(dian)(dian)的(de)(de)(de)鎳氫、鋰離(li)子電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。常(chang)見的(de)(de)(de)干(gan)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)為鋅錳(meng)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，也(ye)被(bei)(bei)稱為碳鋅電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)、堿(jian)性(xing)(xing)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)、鎳鎘電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)與鋰電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)等。這種干(gan)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)一(yi)(yi)種以(yi)糊狀(zhuang)電(dian)(dian)(dian)解液來產生直(zhi)流電(dian)(dian)(dian)的(de)(de)(de)化(hua)學.電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，屬于一(yi)(yi)次電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，是(shi)日常(chang)生活(huo)之中為普遍使(shi)用，以(yi)及輕便的(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。普通干(gan)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)大(da)都是(shi)錳(meng)鋅電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)由碳棒和鋅桶做正負極(ji)，中間是(shi)正極(ji)碳棒，外(wai)包石(shi)墨和二氧化(hua)錳(meng)的(de)(de)(de)混合物(wu)，再外(wai)一(yi)(yi)層是(shi)一(yi)(yi)層纖維網。網上(shang)涂有很厚的(de)(de)(de)電(dian)(dian)(dian)解質糊，其構成(cheng)是(shi)氯化(hua)氨溶液和淀粉，還加有少(shao)量防腐(fu)劑。

人們可(ke)以在(zai)生活(huo)中根據自(zi)己的需要選(xuan)擇電(dian)池，如(ru)(ru)手表(biao)，計算(suan)器(qi)等就可(ke)以選(xuan)擇紐(niu)扣電(dian)池。如(ru)(ru)果是遙控器(qi)，鬧(nao)鐘(zhong)，大鐘(zhong)表(biao)就可(ke)以去選(xuan)擇普通電(dian)池。

二、紐扣電池可以充電嗎

固有印象中，紐扣電池都是一(yi)次(ci)性的(de)，沒電(dian)(dian)(dian)了就(jiu)要更(geng)換(huan)新(xin)電(dian)(dian)(dian)池(chi)(chi)。例如汽車遙控鑰匙上的(de)電(dian)(dian)(dian)池(chi)(chi)，以(yi)及(ji)電(dian)(dian)(dian)腦主板(ban)BIOS芯片的(de)電(dian)(dian)(dian)池(chi)(chi)，總要定(ding)(ding)期更(geng)換(huan)，否則就(jiu)會失靈、失常。不(bu)過技術總在進步，近些年來市場(chang)上出現了一(yi)大批可(ke)以(yi)充(chong)(chong)電(dian)(dian)(dian)的(de)紐(niu)扣(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)，有些廠商不(bu)僅能(neng)(neng)夠提(ti)(ti)供性能(neng)(neng)穩定(ding)(ding)的(de)可(ke)充(chong)(chong)電(dian)(dian)(dian)紐(niu)扣(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)，甚至還提(ti)(ti)供了穩定(ding)(ding)、可(ke)靠的(de)充(chong)(chong)電(dian)(dian)(dian)解(jie)決方案。據(ju)我(wo)了解(jie)，目前比較(jiao)多見(jian)的(de)可(ke)充(chong)(chong)電(dian)(dian)(dian)紐(niu)扣(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)主要有ML（鋰(li)錳電(dian)(dian)(dian)池(chi)(chi)）、LIR（鋰(li)電(dian)(dian)(dian)池(chi)(chi)）、NI-MH（鎳氫電(dian)(dian)(dian)池(chi)(chi)）和NI-Cd（鎳鎘電(dian)(dian)(dian)池(chi)(chi)）四種類型(xing)，這(zhe)四種紐(niu)扣(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)的(de)尺寸、放電(dian)(dian)(dian)電(dian)(dian)(dian)壓、充(chong)(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓、容量、安全特性以(yi)及(ji)市場(chang)價格的(de)信息如下(xia)。

1、ML可充紐扣電(dian)池類(lei)型：鋰錳電(dian)池放電(dian)電(dian)壓：3V充電(dian)電(dian)壓：3V左右容量：1220型電(dian)池的(de)容量多(duo)在10mAh左右。安全特性：安全性和(he)環保性等同于鋰電(dian)池市場價格及應用領域：廣泛應用于攝像頭、筆記本(ben)電(dian)腦(nao)、計算機、傳感器和(he)小型醫(yi)療(liao)設(she)備(bei)中(zhong)；1220型單(dan)顆售價多(duo)在10元左右。

2、LIR可充紐扣電(dian)池類型：鋰電(dian)池放電(dian)電(dian)壓：3.7V充電(dian)電(dian)壓：5V容量：1220型電(dian)池的容量多在(zai)8mAh左右。安(an)全特性：比較(jiao)安(an)全；無(wu)重金屬，比較(jiao)環保。市(shi)場價(jia)格(ge)及應用(yong)(yong)(yong)領域：廣泛(fan)應用(yong)(yong)(yong)于使(shi)用(yong)(yong)(yong)3.7V鋰電(dian)池供電(dian)的小型設備和智(zhi)能設備，1220型單顆售(shou)價(jia)只有3元左右（價(jia)格(ge)便宜）。

3、NI-MH可充紐扣電池(chi)(chi)類型：鎳氫電池(chi)(chi)放電電壓：1.2V（單顆）充電電壓：1.2V左右容(rong)量：1220型電池(chi)(chi)的容(rong)量多在15mAh左右。安(an)全特性：比(bi)(bi)較(jiao)安(an)全；無重(zhong)金(jin)屬，比(bi)(bi)較(jiao)環保。市場(chang)價(jia)格(ge)及(ji)應用(yong)領(ling)域：主要(yao)被生產廠(chang)家應用(yong)于電熱水(shui)器、電飯煲、定時器、電動玩具、汽車音響、便攜式錄音筆(bi)、稅控加油機(ji)、收銀(yin)機(ji)等設(she)備，一組三粒(li)串(chuan)聯(lian)、容(rong)量40mAh的非標準尺寸NI-MH可充紐扣電池(chi)(chi)售價(jia)只有6元左右，價(jia)格(ge)非常便宜。

4、NI-Cd可充(chong)紐扣(kou)電(dian)池類(lei)型：鎳鎘電(dian)池放(fang)電(dian)電(dian)壓(ya)、充(chong)電(dian)電(dian)壓(ya)、容量等方面均與NI-MH（鎳氫）電(dian)池相近(jin)，但由于鎘是(shi)一種重金屬(shu)，如果(guo)回收不(bu)當可能會對環(huan)境(jing)造(zao)成污(wu)染。正是(shi)由于其不(bu)環(huan)保的特(te)性，目前(qian)的應用越來越少（價格倒是(shi)非常便(bian)宜）。
