Description
安全性を損なう原因には、まず一つ目はセパレーターの電解質の液漏れがある。液漏れがあると溶質の六フッ化リン酸リチウムは水で分解し、人体に毒であるフッ酸を放出し、かつ引火性もあり、非常に危険である。また、二つ目は過充電の恐れがある。過充電状態では正極物質から酸素(O)が放出され、発火の原因となる。さらに、三つ目は短絡の恐れがある。短絡が発生すると急速にセル内が高温になり、発火に至る恐れがある。この短絡には内部短絡と外部短絡があり、内部短絡は製造過程での金属性の混入物により、短絡が生じるが、現在では工場での管理が行き届き内部短絡の恐れはない。一方、外部短絡のおそれは依然としてある。
複数のリード線を介して正極及び/又は負極のターミナルに接続しているため、内部で発生する熱は正極又は負極のターミナル1、2に伝搬され、これらのターミナル1,2と一体なフランジ3、4、更にはラミネートフィルム9から成る電池セルAの表面全体で放熱され、温度上昇を抑えることができる。
