Abstract
(EN)
Disclosed is a nonaqueous electrolyte secondary battery that is provided with: an electrode body; a nonaqueous electrolyte solution; a metal outer package storing therein the electrode body and the nonaqueous electrolyte solution; and a pressing member that is provided between the electrode body and the outer package. The outer peripheral surface of the electrode body is provided with an exposing section, from which the surface of a negative electrode collector constituting the negative electrode is exposed. The pressing member expands by absorbing the nonaqueous electrolyte solution, and presses the exposing section of the electrode body to the inner surface of the outer package.

L'invention concerne une batterie secondaire à électrolyte non aqueux qui comporte : un corps d'électrode; une solution électrolytique non aqueuse; un boîtier externe métallique stockant dans celui-ci le corps d'électrode et la solution électrolytique non aqueuse; et un élément de pression qui est disposé entre le corps d'électrode et le boîtier externe. La surface périphérique externe du corps d'électrode comprend une section d'exposition, à partir de laquelle la surface d'un collecteur d'électrode négative constituant l'électrode négative est exposée. L'élément de pression se dilate par absorption de la solution électrolytique non aqueuse, et presse la section d'exposition du corps d'électrode à la surface interne du boîtier externe.
