Abstract
【解決手段】内部に捲回電極体を収容する電池ケースと、電池ケースの開口部に接合される蓋体16と、蓋体16に挿通され、蓋体16に設けられる正極端子と捲回電極体とを電気的に接続するリベット53と、蓋体16とリベット53との間に介装され、蓋体16とリベット53とを絶縁する絶縁板90とを備えるリチウムイオン二次電池であって、絶縁板90における蓋体16との当接面及びリベット53との当接面には、絶縁板90が蓋体16とリベット53との間に密着して固定された状態で、外部より視認できる位置に第一突起部93・93が形成される。
【選択図】図2
Description
なお、図1では、リチウムイオン二次電池10を断面視にて模式的に表している。
なお、図2では、電流遮断装置50を断面視にて模式的に表している。また、図2では、後述する第一突起部93・93及び第二突起部94・94が塑性変形した状態を表している。
なお、図3では、電流遮断装置50に組み立てられる前の絶縁板90を断面視にて模式的に表している。
リチウムイオン二次電池10の製造工程では、リベット53の上端縁部53Aと大径縁部53Bとの間にZ端子71と、上ガスケット60と、下ガスケット80と、蓋体16と、絶縁板90とを、挟んで工具によって密着して固定している(かしめている)。
リチウムイオン二次電池10によれば、蓋体16と絶縁板90との密着、並びに、絶縁板90とリベット93との密着を良好にし、絶縁板90が蓋体16とリベット93との間に密着して固定されているかどうかの確認ができる。
