一、紐扣電池和普通電池的區別

紐扣電池與(yu)普通電(dian)池之間，有外(wai)形大小(xiao)，化學成分，內(nei)部電(dian)壓產生(sheng)方式(shi)，材質等的區(qu)別。

紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)也(ye)稱(cheng)扣(kou)(kou)(kou)式電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，是指(zhi)外(wai)形(xing)(xing)尺寸(cun)象一(yi)顆(ke)小紐(niu)(niu)(niu)扣(kou)(kou)(kou)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，一(yi)般(ban)來說直徑(jing)較(jiao)大(da)，厚度較(jiao)薄。它(ta)(ta)的(de)(de)外(wai)形(xing)(xing)猶如一(yi)顆(ke)紐(niu)(niu)(niu)扣(kou)(kou)(kou)，所以也(ye)被(bei)(bei)稱(cheng)為紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。常(chang)見的(de)(de)紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)按(an)化學組成有(you)碳性，堿性，鋅一(yi)氧化銀，鋅一(yi)空(kong)(kong)氣，鋰一(yi)二(er)氧化錳(meng)，鎳(nie)(nie)鎘充電(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，鎳(nie)(nie)氫充電(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)等(deng)。紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)相對(dui)其(qi)他普通電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，使(shi)用(yong)壽(shou)命較(jiao)長。紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)一(yi)般(ban)裝配在設備上面(mian)，規(gui)廠家生產的(de)(de)紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)一(yi)般(ban)較(jiao)長時(shi)間都(dou)不需要進行(xing)更換，這類電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)通常(chang)處(chu)于設備的(de)(de)內部，很(hen)少與外(wai)界進行(xing)直接的(de)(de)接觸，因(yin)此它(ta)(ta)能得到很(hen)好的(de)(de)防(fang)護，使(shi)用(yong)壽(shou)命也(ye)比較(jiao)長。紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)主要的(de)(de)用(yong)途是：計(ji)算器，助聽器，相機，手(shou)表等(deng)小型(xing)物件(jian)上。紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)壓也(ye)比較(jiao)平(ping)(ping)穩(wen)(wen)，電(dian)(dian)(dian)(dian)(dian)(dian)壓平(ping)(ping)穩(wen)(wen)是指(zhi)在持續輸出的(de)(de)過程中(zhong)呈現出平(ping)(ping)穩(wen)(wen)的(de)(de)放電(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)壓狀態(tai)，電(dian)(dian)(dian)(dian)(dian)(dian)流穩(wen)(wen)定(ding)，因(yin)此紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)常(chang)常(chang)被(bei)(bei)用(yong)于精(jing)密儀器中(zhong)。紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)的(de)(de)觸電(dian)(dian)(dian)(dian)(dian)(dian)容量(liang)也(ye)比較(jiao)大(da)，紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)看似體積較(jiao)小，實(shi)則它(ta)(ta)在有(you)限的(de)(de)空(kong)(kong)間儲存了大(da)量(liang)的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)流，能維(wei)持電(dian)(dian)(dian)(dian)(dian)(dian)子設備長時(shi)間持續運轉，紐(niu)(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)使(shi)用(yong)范圍也(ye)非常(chang)的(de)(de)廣(guang)。

二、紐扣電池可以充電嗎

固有印象中，紐扣電池都是(shi)一次性的(de)，沒電(dian)了(le)就(jiu)(jiu)要(yao)更換(huan)新(xin)電(dian)池(chi)(chi)。例如汽(qi)車遙控鑰匙(chi)上的(de)電(dian)池(chi)(chi)，以及電(dian)腦(nao)主板BIOS芯片的(de)電(dian)池(chi)(chi)，總要(yao)定期更換(huan)，否則就(jiu)(jiu)會失靈(ling)、失常。不過技術總在進步，近些年(nian)來市場上出現了(le)一大批可以充電(dian)的(de)紐扣電(dian)池(chi)(chi)，有些廠商不僅能(neng)(neng)夠提供性能(neng)(neng)穩定的(de)可充電(dian)紐扣電(dian)池(chi)(chi)，甚至還(huan)提供了(le)穩定、可靠的(de)充電(dian)解決方案。據我了(le)解，目前(qian)比較多(duo)見(jian)的(de)可充電(dian)紐扣電(dian)池(chi)(chi)主要(yao)有ML（鋰(li)(li)錳(meng)電(dian)池(chi)(chi)）、LIR（鋰(li)(li)電(dian)池(chi)(chi)）、NI-MH（鎳氫電(dian)池(chi)(chi)）和NI-Cd（鎳鎘電(dian)池(chi)(chi)）四種(zhong)類型，這四種(zhong)紐扣電(dian)池(chi)(chi)的(de)尺(chi)寸、放(fang)電(dian)電(dian)壓、充電(dian)電(dian)壓、容量、安全特性以及市場價格的(de)信息如下。

3、NI-MH可充(chong)紐扣電(dian)池類型：鎳(nie)氫(qing)電(dian)池放電(dian)電(dian)壓：1.2V（單顆）充(chong)電(dian)電(dian)壓：1.2V左右容(rong)量(liang)：1220型電(dian)池的容(rong)量(liang)多在15mAh左右。安全特性：比較安全；無(wu)重金屬(shu)，比較環保。市場價(jia)格(ge)及應用(yong)領域：主要(yao)被生產廠(chang)家(jia)應用(yong)于電(dian)熱水器(qi)、電(dian)飯煲、定時器(qi)、電(dian)動玩具、汽車音響、便攜式錄(lu)音筆、稅控加油(you)機、收銀機等設備，一(yi)組三粒串聯、容(rong)量(liang)40mAh的非標準(zhun)尺寸NI-MH可充(chong)紐扣電(dian)池售價(jia)只有6元左右，價(jia)格(ge)非常便宜。
