1. 紐(niu)扣電(dian)(dian)池和(he)電(dian)(dian)池殼體

一般的(de)(de)干電(dian)(dian)(dian)池(chi)(chi)為錳(meng)電(dian)(dian)(dian)池(chi)(chi)或堿電(dian)(dian)(dian)池(chi)(chi)，其(qi)殼體使用(yong)表面處理(li)鋼材(cai)再(zai)經過涂裝即(ji)可，而電(dian)(dian)(dian)子精密儀(yi)器(qi)所使用(yong)的(de)(de)紐扣(kou)電(dian)(dian)(dian)池(chi)(chi)用(yong)材(cai)，處于(yu)表面處理(li)鋼板(ban)和不銹鋼鋼板(ban)的(de)(de)競爭的(de)(de)狀態。在紐扣(kou)電(dian)(dian)(dian)池(chi)(chi)中，有堿電(dian)(dian)(dian)池(chi)(chi)、氧化(hua)銀電(dian)(dian)(dian)池(chi)(chi)、二氧化(hua)錳(meng)鋰電(dian)(dian)(dian)池(chi)(chi)和空氣鋅電(dian)(dian)(dian)池(chi)(chi)等(deng)各種類型電(dian)(dian)(dian)池(chi)(chi)。

不銹(xiu)鋼具有耐腐(fu)蝕性(xing)，適合制作電(dian)池殼體(ti)。但由于耐腐(fu)蝕的(de)(de)氧化(hua)(hua)膜而(er)使(shi)導電(dian)性(xing)惡(e)化(hua)(hua)，因此多(duo)使(shi)用(yong)鍍鎳(nie)的(de)(de)表面處(chu)理(li)鋼(gang)板。不銹(xiu)鋼(gang)亦可以用(yong)于廉價的(de)(de)玩(wan)具類產品(pin)，但在高性(xing)能(neng)產品(pin)中(zhong)，則使(shi)用(yong)鍍鎳(nie)的(de)(de)不銹(xiu)鋼(gang)。在電(dian)池種(zhong)類當中(zhong)，氧化(hua)(hua)銀電(dian)池，二氧化(hua)(hua)錳鋰電(dian)池應用(yong)較廣(guang)。鍍鎳(nie)不銹(xiu)鋼(gang)的(de)(de)代(dai)表型鋼(gang)種(zhong)SUS304鍍鎳(nie)后，使(shi)用(yong)者(zhe)較多(duo)。最(zui)近為(wei)了降(jiang)低生產成本，轉為(wei)使(shi)用(yong)鐵(tie)素體(ti)系列的(de)(de)SUS430不銹(xiu)鋼(gang)鍍鎳(nie)。

 2. 鋰離子電池殼(ke)體

 用(yong)(yong)在(zai)(zai)小(xiao)型鋰(li)離(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)殼(ke)體(ti)材(cai)料中(zhong)，有表(biao)面(mian)(mian)處理(li)鋼(gang)板、不(bu)銹(xiu)(xiu)鋼(gang)和鋁三方(fang)(fang)面(mian)(mian)的(de)(de)(de)競爭，在(zai)(zai)開(kai)發初期(qi)，因為(wei)鋰(li)離(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)存在(zai)(zai)爆(bao)炸危險性(xing)，所以，對表(biao)面(mian)(mian)處理(li)鋼(gang)板和不(bu)銹(xiu)(xiu)鋼(gang)作(zuo)為(wei)殼(ke)體(ti)材(cai)料而(er)展開(kai)研討論(lun)證。因為(wei)小(xiao)型的(de)(de)(de)鋰(li)離(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)是長方(fang)(fang)體(ti)，像使(shi)用(yong)(yong)完畢而(er)扔(reng)掉的(de)(de)(de)打火機那樣形狀，雖然使(shi)用(yong)(yong)表(biao)面(mian)(mian)處理(li)鋼(gang)板并具備(bei)沖(chong)(chong)壓成型性(xing)優(you)勢，但在(zai)(zai)常溫下，靈活充分地使(shi)用(yong)(yong)沖(chong)(chong)壓機床(chuang)，開(kai)發多(duo)種工藝方(fang)(fang)式的(de)(de)(de)沖(chong)(chong)壓技術(shu)，可(ke)以使(shi)用(yong)(yong)不(bu)銹(xiu)(xiu)鋼(gang)進(jin)行超深(shen)度拉深(shen)工藝，制(zhi)造(zao)出不(bu)銹(xiu)(xiu)鋼(gang)產(chan)品化的(de)(de)(de)電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)殼(ke)體(ti)。近來，在(zai)(zai)數碼照相機和手機使(shi)用(yong)(yong)的(de)(de)(de)鋰(li)離(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)，考慮到輕(qing)量化，則(ze)鋁殼(ke)體(ti)鋰(li)離(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)亦產(chan)品化了，在(zai)(zai)使(shi)用(yong)(yong)不(bu)銹(xiu)(xiu)鋼(gang)材(cai)料制(zhi)造(zao)技術(shu)中(zhong)，東京(jing)都大田區的(de)(de)(de)技術(shu)實力(li)很強。沖(chong)(chong)壓行業人員采(cai)用(yong)(yong)超深(shen)拉深(shen)進(jin)行生產(chan)制(zhi)造(zao)。可(ke)以說鋁和不(bu)銹(xiu)(xiu)鋼(gang)在(zai)(zai)鋰(li)離(li)子電(dian)(dian)(dian)(dian)池(chi)(chi)(chi)殼(ke)體(ti)行業存在(zai)(zai)著激烈的(de)(de)(de)材(cai)料競爭。

 大型(xing)鋰離子(zi)電(dian)池，曾以NEDO為(wei)中心(xin)，聯合電(dian)池生產廠家參與(yu)，分別開(kai)發了(le)移動型(xing)和定置型(xing)。圓柱(zhu)形(xing)和長方(fang)體形(xing)的(de)電(dian)池殼(ke)體，使用(yong)(yong)(yong)不(bu)銹(xiu)鋼(gang)(gang)材料(liao)。圓柱(zhu)形(xing)使用(yong)(yong)(yong)激光焊接(jie)制(zhi)造殼(ke)體，長方(fang)體形(xing)則采用(yong)(yong)(yong)超深拉深工(gong)藝(yi)進(jin)行(xing)加(jia)工(gong)，而(er)盒蓋(gai)使用(yong)(yong)(yong)激光焊接(jie)進(jin)行(xing)接(jie)合。雖然正處于開(kai)發階(jie)段，但已經決(jue)定在(zai)(zai)2010年在(zai)(zai)主力客機波音789上(shang)，裝設這種鋰離子(zi)電(dian)池。所(suo)用(yong)(yong)(yong)鋼(gang)(gang)種為(wei)SUS304、SUS304L不(bu)銹(xiu)鋼(gang)(gang)，板厚為(wei)0.6-0.8mm,在(zai)(zai)常溫下利(li)用(yong)(yong)(yong)多道工(gong)序(xu)沖(chong)壓成形(xing)。期望在(zai)(zai)市區內行(xing)駛的(de)電(dian)力驅動而(er)在(zai)(zai)郊區是使用(yong)(yong)(yong)汽油作為(wei)燃料(liao)進(jin)行(xing)驅動的(de)兩種動力汽車，或電(dian)動汽車上(shang)，作為(wei)二次電(dian)池，在(zai)(zai)實用(yong)(yong)(yong)化方(fang)面取得了(le)顯(xian)著進(jin)展。從鍍層(ceng)鋼(gang)(gang)板到不(bu)銹(xiu)鋼(gang)(gang)的(de)不(bu)銹(xiu)鋼(gang)(gang)化的(de)重點(dian)是加(jia)工(gong)性和耐腐蝕性。
