[Means for solving problems]
In order to achieve the above object, the battery of the present invention
A power generation element having an isolate that prevents a short circuit between the positive and negative electrodes and the positive and negative electrodes.
In a battery equipped with a metal resin laminated film case for storing power generation elements,
It characterized by having a cover on an end portion of the power generating element.
この特徴を備える電池によれば、電池に外部応力が加わっても、発電要素の端部にカバーが被せられているので、それによって端部の応力変形が防止され、短絡しにくい。カバーは、例えばポリプロピレン（ＰＰ）、ポリエチレン（ＰＥ）などの成形しやすく、電解液など電池構成体に対して安定な絶縁材料からなる。大きさや形状は限定されないが、それ自体が発電要素よりも変形し難く、且つ頭に帽子を被せる如く発電要素の端部に被せやすいものが好ましい。 According to the battery having this feature, even if an external stress is applied to the battery, the end portion of the power generation element is covered with a cover, which prevents stress deformation at the end portion and makes it difficult to short-circuit. The cover is made of an insulating material such as polypropylene (PP) or polyethylene (PE) that is easy to mold and is stable against the battery component such as an electrolytic solution. Although the size and shape are not limited, it is preferable that the power generation element itself is less deformable than the power generation element and is easily put on the end of the power generation element so as to put a hat on the head.
