- 角形の外装缶の開口を封口体で封口した密閉型電池であって、
前記封口体に、開裂ベントと負極端子とを設けており、
前記開裂ベントは、前記封口体の長手方向における中心に対して、前記外装缶の両端のうちの一方の端部側に片寄って配置されており、
前記外装缶内に、負極集電リード及び正極集電リードが導出された電極体が内蔵されており、
前記負極集電リード及び前記正極集電リードは、前記中心に対し、前記一方の端部の反対側に配置されており、
前記封口体を平面視したときに、前記封口体の長手方向と直交する方向を縦方向とし、前記開裂ベントの前記縦方向の縦中心線と前記外装缶の前記一方の端部との間の距離をXとすると、
前記封口体の長手方向において、前記開裂ベントの前記縦中心線と、前記負極集電リードとの最短距離は、前記X以上であることを特徴とする密閉型電池。 - 前記負極端子は、前記封口体を介してリード体に接続されており、前記封口体の長手方向において、前記開裂ベントの前記縦中心線と、前記リード体との最短距離は、前記X以上である請求項1に記載の密閉型電池。
- 前記負極集電リードは、前記負極端子に対し前記開裂ベント側と反対側に配置されている請求項1又は2に記載の密閉型電池。
