Description
さらに、この電池において、前記突起部の平均高さが、84~1000nmであると良い。
図1は、電池1の斜視図である。図2は、図1におけるA-A断面図である。図1および図2に示すように、電池1は、内部を密閉するケース10、ケース10内に収容されている電極体40、電解液3および絶縁ホルダ5ならびに電極体40に接続されている正極端子部材50および負極端子部材60を有する。
[数式1]
(1)突起部全体には、金属アルミニウムと、酸化アルミニウム(非晶質アルミナおよびα―アルミナ)とが混在する。
(2)突起部の基端部には、非晶質アルミナとα―アルミナとが混在する。言い換えると、α―アルミナの面積/非晶質アルミナの面積>0.01である。
(3)突起部の基端部(根元から20nmの範囲)では、非晶質アルミナの面積よりもα―アルミナの面積の方が広く、言い換えると、非晶質アルミナよりもα―アルミナの方が多く含まれている。
(4)非晶質アルミナおよびα―アルミナに比して少量であるが、突起部の基端部の部分に、金属アルミニウムが含まれている。酸化アルミニウム(非晶質アルミナ+α―アルミナ)の面積/金属アルミニウムの面積+酸化アルミニウムの面積>90%である。
次に、電池1の製造方法について、図11のフローチャートを参照しつつ説明する。電池1の製造方法は、部材準備工程S1、突起部形成工程S2、インサート成形工程S3、蓋アセンブリ完成工程S4、閉塞工程S5、溶接工程S6、注液・封止工程S7および初充電・エージング工程S8を含む。
