Abstract:
(EN) Provided is a secondary cell having a configuration and a structure capable of reliably preventing moisture penetration into the secondary cell. A secondary cell 10A according to the present disclosure is provided with at least one laminated structure which comprises a first electrode member 30, a solid electrolyte layer 50, and a second electrode member 40 and in which at least four side surfaces are covered with a protective layer 60. In the secondary cell 10A, extending portions 30', 40' extending from one end of the electrode members 30, 40 are exposed from the side surface of the protective layer 60. Electrodes 71, 72 connected to the extending portions 30', 40' are formed on the side surface of the protective layer 60. The protective layer 60 and some portions 71', 72' of the electrodes 71, 72 are covered with a packaging member 80. The remaining portions 71", 72" of the electrodes 71, 72 are exposed from the packaging member 80. Connecting portions 91, 92 which cover the electrodes 71, 72 and which are connected to the electrodes 71, 72 are provided on the outer surface of the packaging member 80.
(FR) L'invention concerne une cellule secondaire ayant une configuration et une structure capables d'empêcher de manière fiable la pénétration d'humidité dans la cellule secondaire. Une cellule secondaire 10A selon la présente invention est pourvue d'au moins une structure stratifiée qui comprend un premier élément d'électrode 30, une couche d'électrolyte solide 50, et un second élément d'électrode 40 et dans lequel au moins quatre surfaces latérales sont recouvertes d'une couche de protection 60. Dans la cellule secondaire 10A, des parties d'extension 30 ', 40' s'étendant à partir d'une extrémité des éléments d'électrode 30, 40 sont exposées à partir de la surface latérale de la couche de protection 60. Des électrodes 71, 72 connectées aux parties d'extension 30 ', 40' sont formées sur la surface latérale de la couche de protection 60. La couche de protection 60 et certaines parties 71 ', 72' des électrodes 71, 72 sont recouvertes d'un élément d'emballage 80. Les parties restantes 71 ", 72 " des électrodes 71, 72 sont exposées depuis l'élément d'emballage 80. Des parties de liaison 91, 92 qui recouvrent les électrodes 71, 72 et qui sont connectées aux électrodes 71, 72 sont disposées sur la surface externe de l'élément d'emballage 80.
(JA) 二次電池内部への水分侵入を確実に防止することを可能とする構成、構造を有する二次電池が提供される。本開示の二次電池10Aは、第1電極部材30、固体電解質層50及び第2電極部材40から成り、少なくとも4つの側面が保護層60で被覆された積層構造体を、少なくとも1つ、備えている。二次電池10Aでは、電極部材30,40の一端から延在する延在部30',40'は保護層60の側面から露出しており、保護層60の側面には、延在部30',40'に接続された電極71,72が形成されており、保護層60、電極71,72の一部71',72'は外装部材80で被覆されており、且つ、電極71,72の残部71",72"は外装部材80から露出しており、外装部材80の外面には、電極71,72を覆い、電極71,72に接続された接続部91,92が設けられている。
