Abstract
(EN) Provided is a secondary battery that can ensure safety of the secondary battery even when the thickness of a battery can is thin. The secondary battery of the present invention is a secondary battery that uses a square battery can for the exterior case. The square battery can has a pair of facing main surfaces, and a peripheral surface positioned between the pair of main surfaces, and at least one main surface of the pair of main surfaces has a groove positioned on at least one diagonal line of at least one main surface.
(FR) L'invention concerne une batterie secondaire qui peut assurer la sécurité de la batterie secondaire même lorsque l'épaisseur d'un boîtier de batterie est mince. La batterie secondaire de la présente invention est une batterie secondaire qui utilise une batterie carrée pour le boîtier extérieur. La batterie carrée peut comporter une paire de surfaces principales opposées, et une surface périphérique positionnée entre la paire de surfaces principales, et au moins une surface principale de la paire de surfaces principales comporte une rainure positionnée sur au moins une ligne diagonale d'au moins une surface principale.
(JA) 電池缶の厚さを薄くしても、二次電池の安全性を確保することが可能な二次電池を提供する。本発明の二次電池は、外装ケースに角形電池缶を用いてなる二次電池である。角形電池缶は、対向する一対の主面と、一対の主面の間に位置する周面とを有し、一対の主面の少なくとも一方の主面に、少なくとも一方の主面の少なくとも1本の対角線上に位置する溝を有している。
