2032/2025/2016紐扣(kou)電池(chi)殼
一(yi)、概述:
紐(niu)扣(kou)電(dian)池(chi)(chi)(chi)(chi)(button cell )也稱扣(kou)式電(dian)池(chi)(chi)(chi)(chi),是指外(wai)形(xing)尺寸象一(yi)顆小紐(niu)扣(kou)的(de)電(dian)池(chi)(chi)(chi)(chi),一(yi)般來(lai)說直徑較(jiao)大,厚度較(jiao)薄(相對(dui)于柱狀電(dian)池(chi)(chi)(chi)(chi)如市場上的(de)5號AA等(deng)電(dian)池(chi)(chi)(chi)(chi)).紐(niu)扣(kou)電(dian)池(chi)(chi)(chi)(chi)是從外(wai)形(xing)上來(lai)對(dui)電(dian)池(chi)(chi)(chi)(chi)來(lai)分,同等(deng)對(dui)應(ying)的(de)電(dian)池(chi)(chi)(chi)(chi)分類有柱狀電(dian)池(chi)(chi)(chi)(chi),方形(xing)電(dian)池(chi)(chi)(chi)(chi),異(yi)形(xing)電(dian)池(chi)(chi)(chi)(chi)。
二、基本介紹(shao):
紐扣電(dian)(dian)池(chi)(chi)(chi)也分為(wei)化學(xue)電(dian)(dian)池(chi)(chi)(chi)和物理電(dian)(dian)池(chi)(chi)(chi)兩大類(lei),其化學(xue)電(dian)(dian)池(chi)(chi)(chi)應(ying)用*為(wei)普遍。它們由陽極(ji)(ji) (正(zheng)極(ji)(ji))、陰極(ji)(ji) (負極(ji)(ji))及其電(dian)(dian)解液(ye)等(deng)組(zu)成(cheng)。如右圖所示。它的(de)外表為(wei)不銹鋼材料,并(bing)作為(wei)正(zheng)極(ji)(ji),其負極(ji)(ji)為(wei)不銹鋼的(de)圓形蓋,正(zheng)極(ji)(ji)與(yu)負極(ji)(ji)間有密封環絕(jue)緣,密封環用尼龍(long)制成(cheng),密封環除起絕(jue)緣作用外,還能(neng)阻止電(dian)(dian)解液(ye)泄漏(lou)。紐扣電(dian)(dian)池(chi)(chi)(chi)的(de)種類(lei)很多(duo),多(duo)數以所用材料命名,如氧(yang)化銀電(dian)(dian)池(chi)(chi)(chi)、鋰電(dian)(dian)池(chi)(chi)(chi)、堿(jian)性錳電(dian)(dian)池(chi)(chi)(chi)等(deng)。
三(san)、類(lei)(lei)型型號分(fen)類(lei)(lei)
紐扣電池的(de)(de)(de)型號名稱前(qian)面的(de)(de)(de)英文字(zi)(zi)母表(biao)示(shi)電池的(de)(de)(de)種類,數(shu)字(zi)(zi)表(biao)示(shi)尺寸,前(qian)兩位數(shu)字(zi)(zi)表(biao)示(shi)直徑,后兩位表(biao)示(shi)厚度(du);
四、應用

2、組裝方法/工(gong)藝流程
3、極片制備
4、扣式電(dian)池封裝(zhuang)
5、性能測(ce)試
