一、紐扣電池和普通電池的區別

紐扣電池與普通(tong)電池(chi)之間(jian)，有外形大小，化學成分，內部電壓產生方式，材質(zhi)等的區別。

二、紐扣電池可以充電嗎

固有印象中，紐扣電池都是(shi)一次性(xing)(xing)的(de)，沒電(dian)(dian)(dian)(dian)(dian)(dian)了就要(yao)(yao)更換(huan)新電(dian)(dian)(dian)(dian)(dian)(dian)池。例如汽車遙控鑰(yao)匙上的(de)電(dian)(dian)(dian)(dian)(dian)(dian)池，以(yi)及(ji)電(dian)(dian)(dian)(dian)(dian)(dian)腦主板BIOS芯片的(de)電(dian)(dian)(dian)(dian)(dian)(dian)池，總要(yao)(yao)定期更換(huan)，否則(ze)就會失靈、失常。不過技術(shu)總在進(jin)步(bu)，近些年(nian)來市場上出(chu)現了一大(da)批可以(yi)充電(dian)(dian)(dian)(dian)(dian)(dian)的(de)紐扣電(dian)(dian)(dian)(dian)(dian)(dian)池，有(you)些廠商不僅能夠提(ti)供(gong)性(xing)(xing)能穩定的(de)可充電(dian)(dian)(dian)(dian)(dian)(dian)紐扣電(dian)(dian)(dian)(dian)(dian)(dian)池，甚至還提(ti)供(gong)了穩定、可靠的(de)充電(dian)(dian)(dian)(dian)(dian)(dian)解(jie)(jie)決(jue)方(fang)案。據我了解(jie)(jie)，目前(qian)比(bi)較多見的(de)可充電(dian)(dian)(dian)(dian)(dian)(dian)紐扣電(dian)(dian)(dian)(dian)(dian)(dian)池主要(yao)(yao)有(you)ML（鋰(li)錳電(dian)(dian)(dian)(dian)(dian)(dian)池）、LIR（鋰(li)電(dian)(dian)(dian)(dian)(dian)(dian)池）、NI-MH（鎳氫電(dian)(dian)(dian)(dian)(dian)(dian)池）和(he)NI-Cd（鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)池）四種類型，這四種紐扣電(dian)(dian)(dian)(dian)(dian)(dian)池的(de)尺(chi)寸、放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓、充電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓、容量、安全(quan)特性(xing)(xing)以(yi)及(ji)市場價格的(de)信息如下(xia)。

1、ML可充(chong)紐扣電(dian)池類型：鋰錳電(dian)池放電(dian)電(dian)壓(ya)(ya)：3V充(chong)電(dian)電(dian)壓(ya)(ya)：3V左右容量(liang)：1220型電(dian)池的容量(liang)多在(zai)10mAh左右。安全特性(xing)：安全性(xing)和環(huan)保(bao)性(xing)等同于鋰電(dian)池市場價格及應用領(ling)域(yu)：廣泛應用于攝像頭、筆(bi)記本(ben)電(dian)腦(nao)、計算(suan)機、傳感器和小(xiao)型醫療(liao)設備中；1220型單(dan)顆售價多在(zai)10元左右。

2、LIR可充紐扣電(dian)池(chi)(chi)類型：鋰(li)電(dian)池(chi)(chi)放(fang)電(dian)電(dian)壓(ya)：3.7V充電(dian)電(dian)壓(ya)：5V容量：1220型電(dian)池(chi)(chi)的容量多(duo)在8mAh左右。安全特性(xing)：比較安全；無(wu)重金屬，比較環保。市場(chang)價格(ge)(ge)及應用領域：廣(guang)泛應用于使用3.7V鋰(li)電(dian)池(chi)(chi)供電(dian)的小(xiao)型設備和智能設備，1220型單顆售(shou)價只有3元左右（價格(ge)(ge)便(bian)宜(yi)）。

3、NI-MH可充紐扣電(dian)(dian)(dian)池(chi)類型(xing)：鎳氫電(dian)(dian)(dian)池(chi)放電(dian)(dian)(dian)電(dian)(dian)(dian)壓：1.2V（單顆）充電(dian)(dian)(dian)電(dian)(dian)(dian)壓：1.2V左(zuo)(zuo)右(you)容(rong)量：1220型(xing)電(dian)(dian)(dian)池(chi)的容(rong)量多在15mAh左(zuo)(zuo)右(you)。安(an)全(quan)特性：比(bi)(bi)較(jiao)安(an)全(quan)；無重金屬，比(bi)(bi)較(jiao)環保。市場價(jia)(jia)格(ge)及應(ying)用領域(yu)：主要被生(sheng)產廠(chang)家應(ying)用于(yu)電(dian)(dian)(dian)熱(re)水器、電(dian)(dian)(dian)飯煲、定時器、電(dian)(dian)(dian)動(dong)玩具、汽車(che)音響、便攜式(shi)錄音筆、稅控加油機、收銀(yin)機等設(she)備，一組三粒串聯(lian)、容(rong)量40mAh的非標準尺(chi)寸NI-MH可充紐扣電(dian)(dian)(dian)池(chi)售(shou)價(jia)(jia)只有6元左(zuo)(zuo)右(you)，價(jia)(jia)格(ge)非常便宜。

4、NI-Cd可充(chong)紐扣(kou)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(deng)方(fang)面均與NI-MH（鎳氫）電(dian)(dian)池(chi)相近，但由于鎘是一(yi)種重(zhong)金屬，如果回收不(bu)當可能(neng)會對環境(jing)造(zao)成污(wu)染。正(zheng)是由于其不(bu)環保的特性，目前的應用越來越少（價格倒(dao)是非(fei)常便宜(yi)）。
