Description
封止部材の用途は、特に限定されないが、例えば、ガスケット、パッキン等が挙げられる。
封止部材の形状は、環状であって、内側の貫通している部分における貫通方向の一方側と他方側から押圧された状態で用いられ、押圧された状態において、押圧されている方向における圧縮割合が内側よりも外側の方が大きい部分を有しているものであれば特に限定されない。
封止部材の素材としては、特に限定されず、封止部材による封止効果をより長時間得るためには、封止部材の引張弾性率の上限が好ましくは0.8GPaであり、より好ましくは0.7GPaである。また、封止部材の引張弾性率の下限は、好ましくは0.3GPaである。当該引張弾性率の望ましい範囲の根拠は、後述する。
本発明の封止部材は、押圧された状態において、押圧されている方向における圧縮割合が内側よりも外側の方が大きい部分を有していることにより、封止部材が使用された状態で長時間(例えば、20万時間)経過した後であっても、封止部材の反発力が残りやすく、封止効果を良好に維持することができる。
ガスケット51が電池の電極周辺の封止部材として用いられる場合について、押圧される前の状態の例を図23に、押圧された使用状態の例を図24に、それぞれ示す。
