1. 紐扣電池(chi)和電池(chi)殼體

一般的干(gan)電(dian)(dian)(dian)(dian)池為錳(meng)(meng)電(dian)(dian)(dian)(dian)池或(huo)堿電(dian)(dian)(dian)(dian)池，其殼體使用表面處(chu)理鋼(gang)材再經過涂裝即可，而電(dian)(dian)(dian)(dian)子精密(mi)儀器所使用的紐(niu)扣電(dian)(dian)(dian)(dian)池用材，處(chu)于表面處(chu)理鋼(gang)板和不銹鋼(gang)鋼(gang)板的競爭的狀態。在(zai)紐(niu)扣電(dian)(dian)(dian)(dian)池中，有堿電(dian)(dian)(dian)(dian)池、氧化銀電(dian)(dian)(dian)(dian)池、二(er)氧化錳(meng)(meng)鋰(li)電(dian)(dian)(dian)(dian)池和空氣(qi)鋅(xin)電(dian)(dian)(dian)(dian)池等各種類(lei)型電(dian)(dian)(dian)(dian)池。

不銹鋼具有耐腐(fu)蝕性，適合制作電(dian)(dian)池殼體(ti)。但(dan)由于耐腐(fu)蝕的(de)氧化(hua)(hua)膜而(er)使導電(dian)(dian)性惡化(hua)(hua)，因此多使用(yong)(yong)鍍(du)鎳(nie)的(de)表面處理鋼板。不(bu)銹鋼亦可以用(yong)(yong)于廉價(jia)的(de)玩具類(lei)產品，但(dan)在高性能產品中，則使用(yong)(yong)鍍(du)鎳(nie)的(de)不(bu)銹鋼。在電(dian)(dian)池種(zhong)類(lei)當中，氧化(hua)(hua)銀電(dian)(dian)池，二(er)氧化(hua)(hua)錳鋰電(dian)(dian)池應用(yong)(yong)較(jiao)廣。鍍(du)鎳(nie)不(bu)銹鋼的(de)代表型鋼種(zhong)SUS304鍍(du)鎳(nie)后(hou)，使用(yong)(yong)者較(jiao)多。最近(jin)為了降(jiang)低生產成(cheng)本，轉為使用(yong)(yong)鐵素體(ti)系列的(de)SUS430不(bu)銹鋼鍍(du)鎳(nie)。
