Claims (4)
- 正極板と負極板をセパレータを介して積層してなる発電要素がフィルムからなる外装体の内部に電解液とともに収容された偏平なフィルム外装電池を、2つの可動プレートの間に挟み、上記2つの可動プレートを互いに近づく方向に加圧することで、上記発電要素の絶縁状態の検査のために上記フィルム外装電池を加圧するフィルム外装電池の加圧方法において、
上記可動プレートと上記フィルム外装電池が交互に積層された状態で、積層された複数の上記可動プレートおよび複数の上記フィルム外装電池からなる積層体の全体を駆動装置によって積層方向の両側から加圧し、上記駆動装置による上記積層体全体の加圧の際に、所定の時間間隔をあけて複数回に分けて段階的に加圧を行うとともに、
上記複数回の加圧では、加圧力を段階的に大きくすることを特徴とするフィルム外装電池の加圧方法。 - 上記複数回の加圧における各回の加圧の加圧力は、予め設定された所定の下限値以上であることを特徴とする請求項1に記載のフィルム外装電池の加圧方法。
- 上記複数回の加圧における各回の加圧の加圧力は、正極板と負極板をセパレータを介して積層した積層方向に加えられることを特徴とする請求項1に記載のフィルム外装電池の加圧方法。
- 上記可動プレートは、矩形板状を呈し、上記可動プレートの4隅を貫通するガイドロッドによって支持され、締付用ロッドの回転に伴いフィルム外装電池に加圧力が加わるように上記ガイドロッドに沿って平行移動可能なものであって、
上記ガイドロッドは、上記積層体を収容するハウジングの前壁に固定され、
上記締付用ロッドは、上記ハウジングの上記前壁に形成されたネジ孔に螺合するネジ部が形成されたものであり、
上記駆動装置は、上記締付用ロッドを回転させて上記締付用ロッドの上記ネジ部を上記前壁のネジ孔に対して相対的に回転させることにより、上記締付用ロッドによって上記積層体全体を加圧するナットランナであることを特徴とする請求項1〜3のいずれかに記載のフィルム外装電池の加圧方法。
