一、紐扣電池和普通電池的區別

紐扣電池與(yu)普(pu)通(tong)電池之間，有外形大小，化學成(cheng)分，內部電壓產生方(fang)式，材質等(deng)的區(qu)別。

紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)也稱扣(kou)(kou)(kou)(kou)(kou)式電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)，是指外(wai)形尺寸象一(yi)(yi)顆小(xiao)紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)的(de)(de)(de)(de)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)，一(yi)(yi)般(ban)來說(shuo)直(zhi)徑較大(da)，厚度較薄。它(ta)的(de)(de)(de)(de)外(wai)形猶如一(yi)(yi)顆紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)，所以也被稱為紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)。常(chang)(chang)(chang)見的(de)(de)(de)(de)紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)按化學組(zu)成有(you)碳性，堿性，鋅(xin)一(yi)(yi)氧化銀(yin)，鋅(xin)一(yi)(yi)空氣，鋰(li)一(yi)(yi)二氧化錳，鎳鎘充電(dian)(dian)(dian)紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)，鎳氫充電(dian)(dian)(dian)紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)等。紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)相對(dui)其他普通電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)，使(shi)用(yong)壽(shou)命(ming)較長(chang)(chang)。紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)一(yi)(yi)般(ban)裝配在設(she)(she)備(bei)上(shang)面，規廠(chang)家生產的(de)(de)(de)(de)紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)一(yi)(yi)般(ban)較長(chang)(chang)時(shi)(shi)間都不需要進行(xing)更換，這類(lei)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)通常(chang)(chang)(chang)處于設(she)(she)備(bei)的(de)(de)(de)(de)內部，很(hen)少與外(wai)界(jie)進行(xing)直(zhi)接的(de)(de)(de)(de)接觸，因此它(ta)能得到很(hen)好(hao)的(de)(de)(de)(de)防護，使(shi)用(yong)壽(shou)命(ming)也比較長(chang)(chang)。紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)主要的(de)(de)(de)(de)用(yong)途是：計(ji)算器，助聽器，相機，手表等小(xiao)型物件上(shang)。紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)電(dian)(dian)(dian)壓(ya)也比較平穩(wen)(wen)(wen)，電(dian)(dian)(dian)壓(ya)平穩(wen)(wen)(wen)是指在持續輸出(chu)的(de)(de)(de)(de)過程中(zhong)呈現出(chu)平穩(wen)(wen)(wen)的(de)(de)(de)(de)放電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)狀(zhuang)態，電(dian)(dian)(dian)流穩(wen)(wen)(wen)定(ding)，因此紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)常(chang)(chang)(chang)常(chang)(chang)(chang)被用(yong)于精密儀器中(zhong)。紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)的(de)(de)(de)(de)觸電(dian)(dian)(dian)容量(liang)也比較大(da)，紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)看似體積(ji)較小(xiao)，實則它(ta)在有(you)限的(de)(de)(de)(de)空間儲存(cun)了大(da)量(liang)的(de)(de)(de)(de)電(dian)(dian)(dian)流，能維持電(dian)(dian)(dian)子(zi)設(she)(she)備(bei)長(chang)(chang)時(shi)(shi)間持續運轉，紐(niu)(niu)(niu)(niu)扣(kou)(kou)(kou)(kou)(kou)電(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)(chi)(chi)使(shi)用(yong)范圍也非常(chang)(chang)(chang)的(de)(de)(de)(de)廣。

普(pu)通(tong)電(dian)(dian)(dian)(dian)池(chi)(chi)也(ye)就是(shi)(shi)(shi)(shi)常(chang)(chang)用的(de)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)，比(bi)如7號(hao)電(dian)(dian)(dian)(dian)池(chi)(chi)。7號(hao)電(dian)(dian)(dian)(dian)池(chi)(chi)也(ye)被稱作AAA電(dian)(dian)(dian)(dian)池(chi)(chi)，是(shi)(shi)(shi)(shi)一(yi)種常(chang)(chang)見的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)，電(dian)(dian)(dian)(dian)池(chi)(chi)呈圓柱形，高(gao)43.6毫米(mi)，直徑10.1毫米(mi)。常(chang)(chang)用于體積較小，耗電(dian)(dian)(dian)(dian)量不太高(gao)的(de)電(dian)(dian)(dian)(dian)子產品。既有(you)一(yi)次性的(de)堿(jian)性電(dian)(dian)(dian)(dian)池(chi)(chi)，也(ye)有(you)可充電(dian)(dian)(dian)(dian)的(de)鎳氫(qing)、鋰離子電(dian)(dian)(dian)(dian)池(chi)(chi)。常(chang)(chang)見的(de)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)為(wei)鋅錳(meng)(meng)電(dian)(dian)(dian)(dian)池(chi)(chi)，也(ye)被稱為(wei)碳鋅電(dian)(dian)(dian)(dian)池(chi)(chi)、堿(jian)性電(dian)(dian)(dian)(dian)池(chi)(chi)、鎳鎘電(dian)(dian)(dian)(dian)池(chi)(chi)與(yu)鋰電(dian)(dian)(dian)(dian)池(chi)(chi)等。這種干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)(shi)(shi)(shi)一(yi)種以(yi)糊(hu)狀(zhuang)電(dian)(dian)(dian)(dian)解液(ye)來(lai)產生(sheng)直流電(dian)(dian)(dian)(dian)的(de)化學(xue).電(dian)(dian)(dian)(dian)池(chi)(chi)，屬于一(yi)次電(dian)(dian)(dian)(dian)池(chi)(chi)，是(shi)(shi)(shi)(shi)日(ri)常(chang)(chang)生(sheng)活之中(zhong)為(wei)普(pu)遍使用，以(yi)及輕便的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)。普(pu)通(tong)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)大都是(shi)(shi)(shi)(shi)錳(meng)(meng)鋅電(dian)(dian)(dian)(dian)池(chi)(chi)，電(dian)(dian)(dian)(dian)池(chi)(chi)是(shi)(shi)(shi)(shi)由碳棒(bang)和鋅桶做正負極，中(zhong)間是(shi)(shi)(shi)(shi)正極碳棒(bang)，外(wai)包(bao)石(shi)墨和二氧化錳(meng)(meng)的(de)混合物(wu)，再(zai)外(wai)一(yi)層(ceng)是(shi)(shi)(shi)(shi)一(yi)層(ceng)纖維(wei)網(wang)(wang)。網(wang)(wang)上(shang)涂(tu)有(you)很厚的(de)電(dian)(dian)(dian)(dian)解質(zhi)糊(hu)，其構(gou)成是(shi)(shi)(shi)(shi)氯化氨溶液(ye)和淀(dian)粉，還加有(you)少量防腐劑。

二、紐扣電池可以充電嗎

固有印象中，紐扣電池都是一(yi)(yi)次(ci)性的(de)，沒電(dian)(dian)(dian)了就要更(geng)換新電(dian)(dian)(dian)池。例如汽車遙控鑰匙上的(de)電(dian)(dian)(dian)池，以(yi)及電(dian)(dian)(dian)腦(nao)主(zhu)板BIOS芯片的(de)電(dian)(dian)(dian)池，總要定期更(geng)換，否則就會失靈、失常。不(bu)過技術總在進步，近些(xie)年來市場(chang)上出(chu)現了一(yi)(yi)大批可以(yi)充(chong)電(dian)(dian)(dian)的(de)紐(niu)扣電(dian)(dian)(dian)池，有(you)些(xie)廠(chang)商不(bu)僅能夠提(ti)供(gong)性能穩(wen)定的(de)可充(chong)電(dian)(dian)(dian)紐(niu)扣電(dian)(dian)(dian)池，甚至還(huan)提(ti)供(gong)了穩(wen)定、可靠的(de)充(chong)電(dian)(dian)(dian)解決方(fang)案(an)。據我了解，目(mu)前比較多見(jian)的(de)可充(chong)電(dian)(dian)(dian)紐(niu)扣電(dian)(dian)(dian)池主(zhu)要有(you)ML（鋰錳電(dian)(dian)(dian)池）、LIR（鋰電(dian)(dian)(dian)池）、NI-MH（鎳氫電(dian)(dian)(dian)池）和NI-Cd（鎳鎘電(dian)(dian)(dian)池）四種類型，這四種紐(niu)扣電(dian)(dian)(dian)池的(de)尺寸、放(fang)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)、充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)、容量、安全特性以(yi)及市場(chang)價格的(de)信息如下。

3、NI-MH可(ke)充紐扣(kou)電(dian)池(chi)(chi)類型(xing)(xing)：鎳氫電(dian)池(chi)(chi)放電(dian)電(dian)壓(ya)(ya)：1.2V（單顆）充電(dian)電(dian)壓(ya)(ya)：1.2V左(zuo)(zuo)右(you)容(rong)(rong)量(liang)：1220型(xing)(xing)電(dian)池(chi)(chi)的容(rong)(rong)量(liang)多在15mAh左(zuo)(zuo)右(you)。安(an)全特性：比較(jiao)安(an)全；無重金屬，比較(jiao)環保。市場(chang)價格(ge)及(ji)應用領(ling)域：主要(yao)被(bei)生產廠家應用于電(dian)熱(re)水器(qi)、電(dian)飯(fan)煲、定時器(qi)、電(dian)動(dong)玩(wan)具、汽車音響(xiang)、便攜式錄音筆、稅控加油機、收銀機等設備，一組三粒(li)串(chuan)聯(lian)、容(rong)(rong)量(liang)40mAh的非(fei)標準(zhun)尺寸NI-MH可(ke)充紐扣(kou)電(dian)池(chi)(chi)售價只(zhi)有6元左(zuo)(zuo)右(you)，價格(ge)非(fei)常便宜。

4、NI-Cd可充(chong)紐扣電(dian)(dian)池(chi)類型：鎳鎘電(dian)(dian)池(chi)放電(dian)(dian)電(dian)(dian)壓、充(chong)電(dian)(dian)電(dian)(dian)壓、容(rong)量等方面均與NI-MH（鎳氫）電(dian)(dian)池(chi)相近，但(dan)由(you)于鎘是一種重(zhong)金屬，如果回收不當可能會對環境造成(cheng)污染。正是由(you)于其不環保的特性(xing)，目前的應(ying)用越來越少（價格倒(dao)是非常便宜）。
