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(shi)，材質等(deng)的區別(bie)。

紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池也(ye)(ye)稱扣(kou)(kou)(kou)式(shi)電(dian)(dian)(dian)池，是指外(wai)形尺寸象一(yi)(yi)顆小紐(niu)(niu)扣(kou)(kou)(kou)的(de)(de)電(dian)(dian)(dian)池，一(yi)(yi)般(ban)來說直徑(jing)較(jiao)大(da)，厚度(du)較(jiao)薄。它的(de)(de)外(wai)形猶如一(yi)(yi)顆紐(niu)(niu)扣(kou)(kou)(kou)，所以也(ye)(ye)被(bei)(bei)稱為紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池。常見的(de)(de)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池按化(hua)(hua)(hua)學(xue)組成有(you)(you)碳性，堿性，鋅(xin)一(yi)(yi)氧化(hua)(hua)(hua)銀，鋅(xin)一(yi)(yi)空氣(qi)，鋰(li)一(yi)(yi)二氧化(hua)(hua)(hua)錳(meng)，鎳(nie)鎘充(chong)電(dian)(dian)(dian)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池，鎳(nie)氫充(chong)電(dian)(dian)(dian)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池等。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池相對其他普通(tong)電(dian)(dian)(dian)池，使(shi)(shi)用(yong)壽命較(jiao)長(chang)(chang)(chang)。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池一(yi)(yi)般(ban)裝配(pei)在設(she)備上面，規廠家(jia)生產的(de)(de)紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池一(yi)(yi)般(ban)較(jiao)長(chang)(chang)(chang)時(shi)間都不需要進行(xing)更換(huan)，這(zhe)類電(dian)(dian)(dian)池通(tong)常處于(yu)設(she)備的(de)(de)內(nei)部，很少與外(wai)界進行(xing)直接的(de)(de)接觸，因此它能得到(dao)很好(hao)的(de)(de)防護，使(shi)(shi)用(yong)壽命也(ye)(ye)比較(jiao)長(chang)(chang)(chang)。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池主要的(de)(de)用(yong)途(tu)是：計算器，助(zhu)聽器，相機，手表(biao)等小型物(wu)件上。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池的(de)(de)電(dian)(dian)(dian)壓也(ye)(ye)比較(jiao)平(ping)(ping)穩(wen)(wen)，電(dian)(dian)(dian)壓平(ping)(ping)穩(wen)(wen)是指在持續輸(shu)出(chu)的(de)(de)過程中呈(cheng)現出(chu)平(ping)(ping)穩(wen)(wen)的(de)(de)放電(dian)(dian)(dian)電(dian)(dian)(dian)壓狀態，電(dian)(dian)(dian)流穩(wen)(wen)定，因此紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池常常被(bei)(bei)用(yong)于(yu)精(jing)密儀器中。紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池的(de)(de)觸電(dian)(dian)(dian)容量也(ye)(ye)比較(jiao)大(da)，紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池看似體積較(jiao)小，實則它在有(you)(you)限(xian)的(de)(de)空間儲存了大(da)量的(de)(de)電(dian)(dian)(dian)流，能維(wei)持電(dian)(dian)(dian)子(zi)設(she)備長(chang)(chang)(chang)時(shi)間持續運(yun)轉，紐(niu)(niu)扣(kou)(kou)(kou)電(dian)(dian)(dian)池使(shi)(shi)用(yong)范圍也(ye)(ye)非常的(de)(de)廣。

普通(tong)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)也(ye)就是(shi)常(chang)用的干電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，比(bi)如7號電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。7號電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)也(ye)被稱(cheng)作(zuo)AAA電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，是(shi)一(yi)(yi)種常(chang)見的電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)呈(cheng)圓柱形，高43.6毫米，直徑10.1毫米。常(chang)用于體積較小，耗電(dian)(dian)(dian)(dian)量(liang)不太高的電(dian)(dian)(dian)(dian)子產品。既有一(yi)(yi)次(ci)性的堿性電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，也(ye)有可充(chong)電(dian)(dian)(dian)(dian)的鎳氫、鋰離子電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。常(chang)見的干電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)為鋅錳電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，也(ye)被稱(cheng)為碳鋅電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)、堿性電(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。這種干電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)是(shi)一(yi)(yi)種以(yi)糊狀電(dian)(dian)(dian)(dian)解(jie)(jie)液(ye)來產生(sheng)(sheng)直流(liu)電(dian)(dian)(dian)(dian)的化學.電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，屬于一(yi)(yi)次(ci)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，是(shi)日常(chang)生(sheng)(sheng)活(huo)之中為普遍使用，以(yi)及輕便的電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)。普通(tong)干電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)大都是(shi)錳鋅電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)，電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)(chi)(chi)是(shi)由碳棒和(he)鋅桶(tong)做正(zheng)負極(ji)，中間是(shi)正(zheng)極(ji)碳棒，外包石墨和(he)二(er)氧(yang)化錳的混合物，再外一(yi)(yi)層(ceng)是(shi)一(yi)(yi)層(ceng)纖維網。網上涂有很厚的電(dian)(dian)(dian)(dian)解(jie)(jie)質糊，其(qi)構成(cheng)是(shi)氯化氨溶液(ye)和(he)淀粉，還加(jia)有少量(liang)防腐劑。

人們可(ke)(ke)以在生活中根據自己的需要選擇(ze)電(dian)池(chi)，如(ru)手表，計算器(qi)等就可(ke)(ke)以選擇(ze)紐扣電(dian)池(chi)。如(ru)果是遙(yao)控器(qi)，鬧(nao)鐘，大鐘表就可(ke)(ke)以去選擇(ze)普(pu)通電(dian)池(chi)。

二、紐扣電池可以充電嗎

固有印象中，紐扣電池都是一次性的(de)(de)，沒電(dian)(dian)(dian)(dian)(dian)(dian)(dian)了就(jiu)要(yao)更(geng)換新電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)。例(li)如汽車遙(yao)控鑰匙(chi)上的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，以及電(dian)(dian)(dian)(dian)(dian)(dian)(dian)腦主板BIOS芯片的(de)(de)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，總要(yao)定(ding)期(qi)更(geng)換，否則就(jiu)會失靈、失常。不(bu)過技(ji)術總在進(jin)步，近些(xie)年(nian)來市場上出(chu)現了一大批可以充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)的(de)(de)紐(niu)扣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，有些(xie)廠商(shang)不(bu)僅能夠提供性能穩(wen)定(ding)的(de)(de)可充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)扣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)，甚至還提供了穩(wen)定(ding)、可靠的(de)(de)充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)解決方(fang)案。據我了解，目(mu)前比較多見的(de)(de)可充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)紐(niu)扣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)主要(yao)有ML（鋰錳電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)）、LIR（鋰電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)）、NI-MH（鎳氫電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)）和NI-Cd（鎳鎘電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)）四種類型，這(zhe)四種紐(niu)扣電(dian)(dian)(dian)(dian)(dian)(dian)(dian)池(chi)的(de)(de)尺寸、放電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓、充電(dian)(dian)(dian)(dian)(dian)(dian)(dian)電(dian)(dian)(dian)(dian)(dian)(dian)(dian)壓、容量、安全特性以及市場價格的(de)(de)信息如下。
