Abstract

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.
