Description
図1は、実施例1における角形二次電池の外観斜視図、図2は、実施例1における角形二次電池の分解斜視図である。
角形二次電池100は、扁平状の捲回群3を不図示の電解液と共に電池容器に封入した構造を有している。電池容器は、電池缶1および電池蓋6を備えている。電池缶1は、相対的に面積の大きい一対の対向する幅広側面1bと相対的に面積の小さい一対の対向する幅狭側面1cと底面1dを有しており、上部は開口部1aによって開放されている。
捲回群3は、負極電極32と正極電極34を間にセパレータ33、35を挟み込んで扁平状に捲回することによって構成されている。捲回群3は、最外周の電極が負極電極32であり、さらにその外側にセパレータ33、35が捲回される。セパレータ33、35は、正極電極34と負極電極32との間を絶縁する役割を有している。
次に、本発明の実施例2について図7及び図8を用いて説明する。なお、実施例1と同様の構成要素には同一の符号を付することでその詳細な説明を省略する。
次に、本発明の実施例3について図9及び図10を用いて説明する。なお、上述の各実施例と同様の構成要素には同一の符号を付することでその詳細な説明を省略する。
次に、本発明の実施例4について図11及び図12を用いて説明する。なお、上述の各実施例と同様の構成要素には同一の符号を付することでその詳細な説明を省略する。

Claims (2)
- 正極電極と負極電極との間にセパレータを介して捲回した扁平状の捲回群と、該捲回群を収容する電池缶と、該電池缶を封止する電池蓋と、該電池蓋に設けられた正極集電板及び負極集電板と、を有する角形二次電池であって、
前記捲回群は、捲回軸方向一方側の端面の扁平状の長円を長辺方向の中心線と、短辺方向の中心線とで4つの領域に分割したとき、前記捲回群の捲回中心に対して対称な一対の対称領域に、複数の正極集電タブと複数の負極集電タブとが分かれて配置され、
前記複数の正極集電タブで構成される正極タブ群及び複数の負極集電タブで構成される負極タブ群は、それぞれ厚さ方向中心に向かって束ねられ、前記正極集電板及び前記負極集電板にそれぞれ接合されることによって前記電池蓋に支持されていることを特徴とする角形二次電池。 - 前記正極集電板の接合端部と前記複数の正極集電タブとの接続位置と、前記負極集電板の接合端部と前記複数の負極集電タブとの接続位置とが、前記捲回群の捲回中心に対して点対称の位置に設けられていることを特徴とする請求項1に記載の角形二次電池。
