Description
〔実施例1〕
図1は、角形二次電池の外観斜視図である。図2は、角形二次電池の分解斜視図である。
図7(a)は実施例2に係る負極集電板の上面図であり、(b)は実施例2に係る絶縁板の上面図である。実施例2が実施例1と相違する点は、正極および負極の集電板の係合部(切欠き)と、絶縁板の位置決め凸部であるので、実施例1の部位と関連する部位には、200番代の符号を付し、相違する機能のみを詳述する。さらにこれ以外の部材は実施例1と同様であるので詳細な説明は省略する。
図8(a)は実施例3に係る負極集電板の上面図であり、(b)は実施例3に係る絶縁板の上面図である。実施例3が実施例1と相違する点は、正極および負極の集電板の係合部と、絶縁板の位置決め凸部とを複数設けた点であるので、実施例1の部位と関連する部位には、300番代の符号を付し、相違する機能のみを詳述する。さらにこれ以外の部材は実施例1と同様であるので詳細な説明は省略する。
図9(a)は実施例4に係る負極集電板の上面図であり、(b)は実施例4に係る絶縁板の上面図である。実施例4が実施例1と相違する点は、正極および負極の集電板の係合部(切欠き)と、絶縁板の位置決め凸部とを複数設けた点であるので、実施例4の部位と関連する部位には、400番代の符号を付し相違する機能のみを詳述する。さらにこれ以外の部材は実施例1と同様であるので詳細な説明は省略する。
図10(a)は実施例5に係る負極集電板の上面図であり、(b)は実施例5に係る絶縁板の上面図である。実施例5が実施例1と相違する点は、負極側接続部、位置決め凸部、および係合部の配置関係である。すなわち、本実施形態では、負極集電板524の負極側接続部522が、実施例1に比べて電池缶の内側に配置され、絶縁板507の位置決め部517とこれに係合する係合部527が電池缶の外側に配置される。このような構造であっても、実施例1と同様の効果を期待することができる。
