Abstract
Description
また、本願の実施例に係る電池10において、電池ユニット100のケース110は、導電部材200を介して電極接続部120と互いに接続されるので、電池ユニット100の電極接続部120がケース110に直接接続されることに対して、電極接続部120とケース110との間の絶縁不良による安全性の問題を改善し、電池10の安全性能を向上させることができる。
他の実施例では、第1の接続部111は、ケース110の外面から突出して設けられ、第2の接続部240は、第1の接続部111の周側に取り囲まれて設けられ、このようにして、第1の接続部111と第2の接続部240との相互接続の安定性を向上させることができる。
さらに他の実施例において、第2の接続部240は、電極接続部120のケース110の外面から突出する高さの差を補うことができるように、導電部材200によりケース110の表面に近づく方向に沿って折り曲げて形成される。
