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，有外形大小，化學成分，內部電(dian)壓產生方(fang)式，材質等的區別(bie)。

紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)也(ye)稱(cheng)扣(kou)(kou)式電(dian)(dian)(dian)(dian)(dian)池(chi)，是指(zhi)(zhi)外(wai)形尺寸象(xiang)一(yi)(yi)顆小紐扣(kou)(kou)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)池(chi)，一(yi)(yi)般來說直徑(jing)較(jiao)大，厚度較(jiao)薄。它的(de)(de)(de)外(wai)形猶如一(yi)(yi)顆紐扣(kou)(kou)，所以也(ye)被稱(cheng)為紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)。常見的(de)(de)(de)紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)按化學組成有(you)碳(tan)性，堿性，鋅(xin)一(yi)(yi)氧化銀，鋅(xin)一(yi)(yi)空(kong)氣，鋰(li)一(yi)(yi)二氧化錳，鎳(nie)鎘(ge)充電(dian)(dian)(dian)(dian)(dian)紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)，鎳(nie)氫充電(dian)(dian)(dian)(dian)(dian)紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)等。紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)相(xiang)對其他普通(tong)電(dian)(dian)(dian)(dian)(dian)池(chi)，使用(yong)(yong)壽命(ming)較(jiao)長。紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)一(yi)(yi)般裝配在設備上面，規廠家生產的(de)(de)(de)紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)一(yi)(yi)般較(jiao)長時間都不(bu)需(xu)要進(jin)行更換，這類電(dian)(dian)(dian)(dian)(dian)池(chi)通(tong)常處于(yu)(yu)設備的(de)(de)(de)內部(bu)，很少與外(wai)界進(jin)行直接的(de)(de)(de)接觸(chu)，因此它能(neng)得到(dao)很好的(de)(de)(de)防護，使用(yong)(yong)壽命(ming)也(ye)比較(jiao)長。紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)主要的(de)(de)(de)用(yong)(yong)途是：計算(suan)器(qi)(qi)，助(zhu)聽器(qi)(qi)，相(xiang)機，手表等小型物(wu)件上。紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)壓也(ye)比較(jiao)平(ping)穩(wen)，電(dian)(dian)(dian)(dian)(dian)壓平(ping)穩(wen)是指(zhi)(zhi)在持續(xu)輸出(chu)的(de)(de)(de)過(guo)程(cheng)中呈現出(chu)平(ping)穩(wen)的(de)(de)(de)放電(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)壓狀態，電(dian)(dian)(dian)(dian)(dian)流穩(wen)定，因此紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)常常被用(yong)(yong)于(yu)(yu)精(jing)密(mi)儀器(qi)(qi)中。紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)(de)觸(chu)電(dian)(dian)(dian)(dian)(dian)容量(liang)也(ye)比較(jiao)大，紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)看(kan)似體積較(jiao)小，實則它在有(you)限(xian)的(de)(de)(de)空(kong)間儲存了大量(liang)的(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)流，能(neng)維(wei)持電(dian)(dian)(dian)(dian)(dian)子設備長時間持續(xu)運轉，紐扣(kou)(kou)電(dian)(dian)(dian)(dian)(dian)池(chi)使用(yong)(yong)范(fan)圍(wei)也(ye)非常的(de)(de)(de)廣。

普通電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)也(ye)(ye)就是常用的(de)(de)(de)(de)干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，比如7號電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。7號電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)也(ye)(ye)被稱(cheng)作AAA電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，是一(yi)種(zhong)常見的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)呈(cheng)圓柱形，高43.6毫(hao)米，直徑10.1毫(hao)米。常用于(yu)體積較(jiao)小，耗電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)量(liang)不太高的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)子產品(pin)。既有一(yi)次性(xing)(xing)(xing)的(de)(de)(de)(de)堿性(xing)(xing)(xing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，也(ye)(ye)有可充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)鎳(nie)(nie)氫、鋰離子電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。常見的(de)(de)(de)(de)干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)為鋅(xin)錳電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，也(ye)(ye)被稱(cheng)為碳(tan)鋅(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)、堿性(xing)(xing)(xing)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)、鎳(nie)(nie)鎘(ge)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)與鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)等。這種(zhong)干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是一(yi)種(zhong)以(yi)糊(hu)狀電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解液來產生(sheng)直流(liu)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)(de)(de)化學.電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，屬(shu)于(yu)一(yi)次電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，是日常生(sheng)活之中為普遍(bian)使用，以(yi)及輕便的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)。普通干(gan)(gan)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)大都是錳鋅(xin)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)，電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)(chi)是由(you)碳(tan)棒和鋅(xin)桶做正負極(ji)，中間是正極(ji)碳(tan)棒，外(wai)包石(shi)墨和二氧(yang)化錳的(de)(de)(de)(de)混合物，再外(wai)一(yi)層是一(yi)層纖(xian)維網。網上涂有很厚(hou)的(de)(de)(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)(dian)解質糊(hu)，其構(gou)成(cheng)是氯化氨溶液和淀粉，還(huan)加有少量(liang)防腐(fu)劑。

人們可(ke)以在生活中根據自己的需要選擇電池，如手表，計算器等就(jiu)可(ke)以選擇紐扣電池。如果是遙控器，鬧鐘，大鐘表就(jiu)可(ke)以去選擇普通電池。

二、紐扣電池可以充電嗎

固有印象中，紐扣電池都是一次性(xing)(xing)的，沒電(dian)(dian)(dian)(dian)了就要(yao)更換新(xin)電(dian)(dian)(dian)(dian)池(chi)(chi)。例如(ru)汽車遙控鑰匙上的電(dian)(dian)(dian)(dian)池(chi)(chi)，以(yi)及電(dian)(dian)(dian)(dian)腦(nao)主(zhu)板BIOS芯片的電(dian)(dian)(dian)(dian)池(chi)(chi)，總(zong)要(yao)定(ding)期(qi)更換，否則就會失靈、失常。不過技(ji)術總(zong)在(zai)進步(bu)，近些(xie)年來市(shi)場上出現了一大批可(ke)(ke)以(yi)充(chong)電(dian)(dian)(dian)(dian)的紐(niu)(niu)扣(kou)電(dian)(dian)(dian)(dian)池(chi)(chi)，有些(xie)廠商不僅能夠提供性(xing)(xing)能穩(wen)定(ding)的可(ke)(ke)充(chong)電(dian)(dian)(dian)(dian)紐(niu)(niu)扣(kou)電(dian)(dian)(dian)(dian)池(chi)(chi)，甚至還提供了穩(wen)定(ding)、可(ke)(ke)靠的充(chong)電(dian)(dian)(dian)(dian)解決方案。據(ju)我了解，目前(qian)比較多見的可(ke)(ke)充(chong)電(dian)(dian)(dian)(dian)紐(niu)(niu)扣(kou)電(dian)(dian)(dian)(dian)池(chi)(chi)主(zhu)要(yao)有ML（鋰(li)錳電(dian)(dian)(dian)(dian)池(chi)(chi)）、LIR（鋰(li)電(dian)(dian)(dian)(dian)池(chi)(chi)）、NI-MH（鎳氫電(dian)(dian)(dian)(dian)池(chi)(chi)）和(he)NI-Cd（鎳鎘(ge)電(dian)(dian)(dian)(dian)池(chi)(chi)）四種類型，這四種紐(niu)(niu)扣(kou)電(dian)(dian)(dian)(dian)池(chi)(chi)的尺(chi)寸、放電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓、充(chong)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓、容量、安全特性(xing)(xing)以(yi)及市(shi)場價格的信(xin)息如(ru)下(xia)。

2、LIR可(ke)充紐(niu)扣(kou)電(dian)(dian)池(chi)(chi)類型(xing)(xing)：鋰(li)電(dian)(dian)池(chi)(chi)放電(dian)(dian)電(dian)(dian)壓(ya)：3.7V充電(dian)(dian)電(dian)(dian)壓(ya)：5V容量：1220型(xing)(xing)電(dian)(dian)池(chi)(chi)的(de)容量多(duo)在8mAh左右。安(an)全特性：比(bi)較安(an)全；無重(zhong)金(jin)屬(shu)，比(bi)較環保。市(shi)場(chang)價格及(ji)應(ying)用(yong)領域：廣泛應(ying)用(yong)于使用(yong)3.7V鋰(li)電(dian)(dian)池(chi)(chi)供電(dian)(dian)的(de)小型(xing)(xing)設備和(he)智能設備，1220型(xing)(xing)單顆售價只有3元左右（價格便宜）。

3、NI-MH可充(chong)紐扣電(dian)(dian)(dian)池類型：鎳氫電(dian)(dian)(dian)池放電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)：1.2V（單顆）充(chong)電(dian)(dian)(dian)電(dian)(dian)(dian)壓(ya)：1.2V左右容量：1220型電(dian)(dian)(dian)池的容量多(duo)在15mAh左右。安全特性：比(bi)較安全；無重金屬，比(bi)較環保。市場價格及應(ying)用(yong)領域：主要被生產廠家應(ying)用(yong)于電(dian)(dian)(dian)熱水器、電(dian)(dian)(dian)飯煲、定時器、電(dian)(dian)(dian)動玩具、汽(qi)車音響、便攜式(shi)錄(lu)音筆(bi)、稅控加油機(ji)、收銀機(ji)等設(she)備，一(yi)組三粒串聯、容量40mAh的非標準尺寸NI-MH可充(chong)紐扣電(dian)(dian)(dian)池售價只有6元左右，價格非常便宜。

4、NI-Cd可充紐扣電(dian)(dian)(dian)(dian)池類型：鎳(nie)鎘電(dian)(dian)(dian)(dian)池放(fang)電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓、充電(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)壓、容量(liang)等方面均與NI-MH（鎳(nie)氫）電(dian)(dian)(dian)(dian)池相近，但由于(yu)鎘是一種重(zhong)金屬(shu)，如果回收不(bu)當可能會對環境造成(cheng)污染。正是由于(yu)其不(bu)環保的特(te)性，目前的應用越(yue)(yue)來越(yue)(yue)少（價格倒是非常(chang)便宜）。
