一、紐扣電池和普通電池的區別

紐扣電池與普通電(dian)池之間，有外(wai)形大(da)小，化學成分，內部(bu)電(dian)壓產生(sheng)方(fang)式，材質等的區別(bie)。

紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)也(ye)(ye)稱(cheng)扣(kou)(kou)(kou)式電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，是指(zhi)外形尺(chi)寸象一(yi)顆小紐(niu)(niu)扣(kou)(kou)(kou)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，一(yi)般(ban)來說直(zhi)徑較(jiao)(jiao)大，厚(hou)度較(jiao)(jiao)薄(bo)。它的(de)(de)(de)(de)外形猶如一(yi)顆紐(niu)(niu)扣(kou)(kou)(kou)，所(suo)以也(ye)(ye)被(bei)稱(cheng)為紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。常(chang)見(jian)的(de)(de)(de)(de)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)按化學組成有(you)碳性，堿性，鋅一(yi)氧(yang)化銀，鋅一(yi)空氣，鋰一(yi)二氧(yang)化錳，鎳鎘充電(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，鎳氫充電(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)等。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)相對(dui)其(qi)他普通電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，使(shi)用(yong)壽命較(jiao)(jiao)長。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)一(yi)般(ban)裝(zhuang)配在(zai)(zai)設(she)備(bei)上面，規廠(chang)家生產的(de)(de)(de)(de)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)一(yi)般(ban)較(jiao)(jiao)長時(shi)間(jian)都(dou)不需要進行更換，這(zhe)類電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)通常(chang)處(chu)于設(she)備(bei)的(de)(de)(de)(de)內部，很少與外界(jie)進行直(zhi)接的(de)(de)(de)(de)接觸，因此(ci)它能得到很好的(de)(de)(de)(de)防護(hu)，使(shi)用(yong)壽命也(ye)(ye)比較(jiao)(jiao)長。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)主要的(de)(de)(de)(de)用(yong)途是：計算器，助(zhu)聽(ting)器，相機，手表等小型(xing)物(wu)件(jian)上。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)也(ye)(ye)比較(jiao)(jiao)平(ping)穩(wen)，電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)平(ping)穩(wen)是指(zhi)在(zai)(zai)持(chi)續輸(shu)出(chu)的(de)(de)(de)(de)過程中(zhong)呈現出(chu)平(ping)穩(wen)的(de)(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)狀態，電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)穩(wen)定，因此(ci)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)常(chang)常(chang)被(bei)用(yong)于精密儀器中(zhong)。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)的(de)(de)(de)(de)觸電(dian)(dian)(dian)(dian)(dian)(dian)容(rong)量(liang)也(ye)(ye)比較(jiao)(jiao)大，紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)看似體積較(jiao)(jiao)小，實則(ze)它在(zai)(zai)有(you)限的(de)(de)(de)(de)空間(jian)儲存了(le)大量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流(liu)，能維持(chi)電(dian)(dian)(dian)(dian)(dian)(dian)子設(she)備(bei)長時(shi)間(jian)持(chi)續運(yun)轉，紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)使(shi)用(yong)范圍也(ye)(ye)非(fei)常(chang)的(de)(de)(de)(de)廣。

普通電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)也(ye)就(jiu)是(shi)常(chang)用的(de)(de)干電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，比如7號(hao)(hao)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。7號(hao)(hao)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)也(ye)被稱作AAA電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，是(shi)一(yi)種常(chang)見的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)呈圓(yuan)柱形，高43.6毫米(mi)，直徑10.1毫米(mi)。常(chang)用于(yu)(yu)體積較(jiao)小，耗電(dian)(dian)(dian)(dian)(dian)(dian)量(liang)不太高的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)子產(chan)品。既有(you)一(yi)次(ci)(ci)性(xing)的(de)(de)堿(jian)性(xing)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，也(ye)有(you)可充電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)鎳氫(qing)、鋰離(li)子電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。常(chang)見的(de)(de)干電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)為鋅(xin)錳(meng)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，也(ye)被稱為碳鋅(xin)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)、堿(jian)性(xing)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)、鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)與鋰電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)等。這(zhe)種干電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)一(yi)種以(yi)糊狀電(dian)(dian)(dian)(dian)(dian)(dian)解液來產(chan)生直流電(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)化學.電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，屬于(yu)(yu)一(yi)次(ci)(ci)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，是(shi)日常(chang)生活(huo)之中為普遍使用，以(yi)及(ji)輕(qing)便的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。普通干電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)大都是(shi)錳(meng)鋅(xin)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)是(shi)由(you)碳棒和(he)鋅(xin)桶做(zuo)正負極(ji)，中間是(shi)正極(ji)碳棒，外包石墨(mo)和(he)二氧(yang)化錳(meng)的(de)(de)混合物，再外一(yi)層是(shi)一(yi)層纖維網。網上涂有(you)很厚的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)解質糊，其構成(cheng)是(shi)氯化氨溶液和(he)淀(dian)粉，還加有(you)少量(liang)防(fang)腐劑。

二、紐扣電池可以充電嗎

固有印象中，紐扣電池都是(shi)一(yi)次性的(de)(de)，沒電(dian)(dian)(dian)(dian)(dian)了(le)(le)就(jiu)要更換(huan)新電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。例(li)如汽車遙(yao)控鑰匙上的(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，以(yi)及(ji)(ji)電(dian)(dian)(dian)(dian)(dian)腦主(zhu)板BIOS芯片的(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，總要定(ding)期更換(huan)，否(fou)則就(jiu)會失靈、失常。不過技術總在進步，近些年來(lai)市(shi)場上出現了(le)(le)一(yi)大批可以(yi)充電(dian)(dian)(dian)(dian)(dian)的(de)(de)紐扣電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，有些廠商(shang)不僅能夠提供性能穩定(ding)的(de)(de)可充電(dian)(dian)(dian)(dian)(dian)紐扣電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，甚至還提供了(le)(le)穩定(ding)、可靠的(de)(de)充電(dian)(dian)(dian)(dian)(dian)解決方(fang)案(an)。據我(wo)了(le)(le)解，目前比較多見的(de)(de)可充電(dian)(dian)(dian)(dian)(dian)紐扣電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)主(zhu)要有ML（鋰錳電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）、LIR（鋰電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）、NI-MH（鎳氫電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）和NI-Cd（鎳鎘電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）四種類型(xing)，這(zhe)四種紐扣電(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)尺寸、放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)、充電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓(ya)、容量、安(an)全特性以(yi)及(ji)(ji)市(shi)場價格的(de)(de)信息如下。
