一、紐扣電池和普通電池的區別

紐扣電池與普通電池之間，有外形大小(xiao)，化學成分，內部電壓產生(sheng)方式，材質等的區別。

紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)也(ye)稱扣(kou)式電(dian)(dian)池(chi)(chi)(chi)(chi)，是指外形(xing)尺(chi)寸象一顆小紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)的(de)(de)(de)電(dian)(dian)池(chi)(chi)(chi)(chi)，一般(ban)來(lai)說直(zhi)徑較(jiao)(jiao)(jiao)大，厚度較(jiao)(jiao)(jiao)薄(bo)。它的(de)(de)(de)外形(xing)猶如一顆紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)，所以(yi)也(ye)被稱為(wei)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)。常見的(de)(de)(de)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)按化(hua)學組成(cheng)有碳性(xing)，堿性(xing)，鋅一氧化(hua)銀，鋅一空氣，鋰一二氧化(hua)錳，鎳(nie)鎘(ge)充(chong)電(dian)(dian)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)，鎳(nie)氫充(chong)電(dian)(dian)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)等。紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)相(xiang)對其他普(pu)通電(dian)(dian)池(chi)(chi)(chi)(chi)，使用壽命較(jiao)(jiao)(jiao)長(chang)(chang)。紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)一般(ban)裝配(pei)在(zai)設備上面，規(gui)廠(chang)家(jia)生(sheng)產(chan)的(de)(de)(de)紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)一般(ban)較(jiao)(jiao)(jiao)長(chang)(chang)時間(jian)都不需要(yao)進(jin)行更換，這(zhe)類電(dian)(dian)池(chi)(chi)(chi)(chi)通常處于設備的(de)(de)(de)內部，很少與外界進(jin)行直(zhi)接的(de)(de)(de)接觸(chu)，因(yin)此它能(neng)得到很好的(de)(de)(de)防護，使用壽命也(ye)比(bi)較(jiao)(jiao)(jiao)長(chang)(chang)。紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)主(zhu)要(yao)的(de)(de)(de)用途是：計算器，助(zhu)聽器，相(xiang)機，手(shou)表等小型物件上。紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)電(dian)(dian)壓也(ye)比(bi)較(jiao)(jiao)(jiao)平(ping)穩，電(dian)(dian)壓平(ping)穩是指在(zai)持續輸(shu)出(chu)的(de)(de)(de)過程中呈現出(chu)平(ping)穩的(de)(de)(de)放電(dian)(dian)電(dian)(dian)壓狀態，電(dian)(dian)流穩定，因(yin)此紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)常常被用于精密儀器中。紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)的(de)(de)(de)觸(chu)電(dian)(dian)容(rong)量也(ye)比(bi)較(jiao)(jiao)(jiao)大，紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)看似體積(ji)較(jiao)(jiao)(jiao)小，實則它在(zai)有限的(de)(de)(de)空間(jian)儲(chu)存(cun)了大量的(de)(de)(de)電(dian)(dian)流，能(neng)維(wei)持電(dian)(dian)子設備長(chang)(chang)時間(jian)持續運轉，紐(niu)(niu)(niu)(niu)(niu)(niu)扣(kou)電(dian)(dian)池(chi)(chi)(chi)(chi)使用范圍(wei)也(ye)非常的(de)(de)(de)廣(guang)。

普(pu)通(tong)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)也就是(shi)(shi)(shi)(shi)常用的(de)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，比如7號(hao)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。7號(hao)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)也被(bei)稱作(zuo)AAA電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，是(shi)(shi)(shi)(shi)一種常見的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)呈圓(yuan)柱形，高43.6毫米，直(zhi)徑(jing)10.1毫米。常用于體積較小，耗電(dian)(dian)(dian)(dian)量不太(tai)高的(de)電(dian)(dian)(dian)(dian)子(zi)(zi)產(chan)(chan)品。既有(you)一次性(xing)(xing)的(de)堿性(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，也有(you)可充電(dian)(dian)(dian)(dian)的(de)鎳氫(qing)、鋰離子(zi)(zi)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。常見的(de)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)為(wei)鋅(xin)錳電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，也被(bei)稱為(wei)碳(tan)鋅(xin)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)、堿性(xing)(xing)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)、鎳鎘電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)與鋰電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)等。這種干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)是(shi)(shi)(shi)(shi)一種以糊狀電(dian)(dian)(dian)(dian)解(jie)(jie)液來(lai)產(chan)(chan)生直(zhi)流(liu)電(dian)(dian)(dian)(dian)的(de)化(hua)學.電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，屬(shu)于一次電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，是(shi)(shi)(shi)(shi)日常生活之中為(wei)普(pu)遍使(shi)用，以及輕便的(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。普(pu)通(tong)干(gan)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)大都是(shi)(shi)(shi)(shi)錳鋅(xin)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)是(shi)(shi)(shi)(shi)由碳(tan)棒和(he)(he)鋅(xin)桶做正(zheng)負極，中間是(shi)(shi)(shi)(shi)正(zheng)極碳(tan)棒，外包石(shi)墨(mo)和(he)(he)二(er)氧化(hua)錳的(de)混合物(wu)，再外一層(ceng)是(shi)(shi)(shi)(shi)一層(ceng)纖(xian)維網(wang)。網(wang)上涂(tu)有(you)很厚的(de)電(dian)(dian)(dian)(dian)解(jie)(jie)質糊，其構成(cheng)是(shi)(shi)(shi)(shi)氯(lv)化(hua)氨溶液和(he)(he)淀粉，還加(jia)有(you)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)是一次性(xing)的(de)，沒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)了就要更換新電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)。例如(ru)汽車遙控鑰匙上的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，以及(ji)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦主(zhu)板BIOS芯片的(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，總要定(ding)期更換，否則就會失(shi)靈(ling)、失(shi)常。不過(guo)技術(shu)總在進步，近(jin)些年來市(shi)場(chang)上出現了一大批可以充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)紐扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，有些廠商不僅(jin)能夠提供性(xing)能穩(wen)定(ding)的(de)可充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)紐扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)，甚至還提供了穩(wen)定(ding)、可靠的(de)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解決方案。據我了解，目(mu)前比較(jiao)多見(jian)的(de)可充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)紐扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)主(zhu)要有ML（鋰錳電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）、LIR（鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）、NI-MH（鎳(nie)氫(qing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）和NI-Cd（鎳(nie)鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)）四(si)種(zhong)類(lei)型，這四(si)種(zhong)紐扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)的(de)尺寸、放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)、充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓(ya)、容量、安(an)全特性(xing)以及(ji)市(shi)場(chang)價(jia)格的(de)信(xin)息(xi)如(ru)下。

3、NI-MH可充紐扣電池(chi)類型(xing)：鎳氫電池(chi)放電電壓(ya)：1.2V（單顆）充電電壓(ya)：1.2V左右容(rong)(rong)量(liang)：1220型(xing)電池(chi)的容(rong)(rong)量(liang)多(duo)在(zai)15mAh左右。安全特(te)性：比較(jiao)安全；無(wu)重金屬，比較(jiao)環(huan)保。市場價(jia)格及(ji)應用領域：主要被(bei)生(sheng)產廠家(jia)應用于電熱水器(qi)、電飯煲、定時器(qi)、電動玩具、汽車(che)音響、便攜式錄音筆、稅控加油機(ji)、收銀(yin)機(ji)等設(she)備，一組三粒串聯(lian)、容(rong)(rong)量(liang)40mAh的非(fei)標準尺寸(cun)NI-MH可充紐扣電池(chi)售價(jia)只有6元左右，價(jia)格非(fei)常便宜。
