Abstract
【解決手段】複数の電池セル1を接続してなる電池パック10において、電池セル1ごとに電解液を吸収する液吸収材18を設ける。また、液吸収材18は電池セル1のガス封止開放部7の近傍に配設する。さらに液吸収材18は難燃性材料からなる。このような構成からなる電池パック10により上記の課題を解決する。
【選択図】図4
Description
そこで、かかる事態を回避するため、リチウムセル1には正負両電極2a,3aが設けられた反対側の端部に安全弁7が設けられている。具体的にはリチウムセル1の内圧が所定圧力以上になると、アルミラミネート6,6の熱溶着部に設けられた弁孔7aへの最短パス7bが開放され、内部ガスを弁孔7aからリチウムセル1外へ放出するようにされている。
7 ガス封止開放部(安全弁)
10 電池パック
18 液吸収材
Claims (3)
- 複数の電池セルを接続してなる電池パックであって、前記電池セルごとに液吸収材を設けたことを特徴とする電池パック。
- 前記液吸収材は電池セルのガス封止開放部の近傍に配設されることを特徴とする請求項1記載の電池パック。
- 前記液吸収材は難燃性材料からなることを特徴とする請求項1または2記載の電池パック。
