Description
電池ケースは、容器と、容器の開口を塞ぐ封口部材とで構成される。容器の形状は、特に限定されず、角形もしくは矩形でもよく、円筒形でもよい。容器としては、例えば有底の金属缶が好ましい。容器のサイズは、用途に応じて適宜選択できる。小型の円筒形電池の場合、容器の外径(すなわち電池の外径)は、例えば10mm以下であり、6mm以下もしくは5mm以下である。金属缶の材質は、特に限定されないが、ステンレス鋼、アルミニウム、鉄、ニッケルなどが用いられる。封口部材の形状も特に限定されず、容器の開口形状に応じた形状を有すればよい。円筒形電池の封口部材は、図示例のように単一の部品であってもよく、安全弁を具備する組み立て品(アセンブリ)であってもよい。また、角形電池の封口部材は、第1電極とだけ電気的に接続されるタイプであってもよく、第1電極と電気的に接続され、第1電極の外部端子として機能する第1部分と、第2電極と電気的に接続され、第2電極の外部端子として機能する第2部分とを具備する組み立て品であってもよい。
電極群は、正極と、負極と、正極および負極の間に介在するセパレータとを含む。電極群の形態は特に制限されず、巻回式でも積層式でもよい。正極は、正極活物質を含んでいればよく、通常、正極集電体と正極集電体の表面に付着した正極活物質層とを含む。負極は、負極活物質を含んでいればよく、通常、負極集電体と、負極集電体の表面に付着した負極活物質層とを含む。
電解質は、非水溶媒と、非水溶媒に溶解した溶質とを含む。
Cr含有量26質量%のステンレス鋼板を成形して、図1に示すような円筒形電池に用いる凸形状を有する封口部材(直径3mm、凸部の厚さ(Ts)1.0mm)を作製した。一方、アルミニウム箔(厚さ(T0)0.1mm)から、幅1mm、長さ10mmのリボン状の第1リードを切り出した。次に、出力面の形状が、第1リードの幅方向における長さ2mm×第1リード長手方向における長さ1mmの矩形で、中央に第1リードの長手方向に沿う0.2mm幅の溝を有する超音波ホーンを用いて、封口部材の内面側に、第1リードの一端を溶接した。その結果、第1リードの全幅にわたって溶着領域が形成され、溶着領域の中央には、超音波ホーンの出力面の溝に沿って、第1リードの長手方向に沿った第1***部(長さ1mm、厚さ(T1)0.15mm)が形成された。第1***部は、溶着領域と非溶着領域との境界にまで達していた。第1***部の両側には薄肉部(厚さ(T2)0.06mm)が形成された。
出力面の形状が、第1リードの幅方向における長さ2mm×第1リードの長手方向における長さ1mmの矩形であり、中央に溝を有さない超音波ホーンを用いたこと以外、実施例1と同様に、封口部材の内面側に、第1リードの一端を溶接した。その結果、第1リードの全幅にわたって溶着領域が形成された。このとき、溶着領域の全体が薄肉部(厚さ(T2)0.055mm)であった。
