Abstract
(EN) The present invention provides: a secondary battery which is prevented from penetration of water vapor from the outside; and a method for producing a secondary battery. A secondary battery 100 which comprises an electrode assembly 10 and an outer package 50 that contains the electrode assembly 10, said secondary battery 100 comprising a terminal member 60 that is electrically connected to the electrode assembly 10, and being provided with an inorganic film 80 that covers at least the region between the terminal member 60 and the outer package 50.
(FR) La présente invention concerne : une batterie secondaire dans laquelle on empêche la vapeur d'eau de pénétrer depuis l'extérieur ; et un procédé de production d'une batterie secondaire. Une batterie secondaire (100) comprend un ensemble électrode (10) et un boîtier externe (50) contient l'ensemble électrode (10), ladite batterie secondaire (100) comprenant un élément formant borne (60) qui est relié électriquement à l'ensemble électrode (10), et pourvu d'un film inorganique (80) qui recouvre au moins la région entre l'élément formant borne (60) et le boîtier externe (50).
(JA) 外部からの水蒸気の侵入を防止する二次電池及び二次電池の製造方法を提供する。電極組立体10および電極組立体10を収納する外装体50を有して成る二次電池100であって、電極組立体10と電気的に接続された端子部材60を有して成り、端子部材60と外装体50との間の領域を少なくとも被覆する無機膜80が設けられている。
