Secondary battery apparatus and method of manufacturing secondary battery apparatus

摘要

A secondary battery apparatus (10) comprising a plurality of battery cells wherein an upper case (18) holds the terminal surfaces (320) of said cells, a lower case (16) supports the lower end portions (330) of said cells and wherein the plurality of battery cells are bonded to the lower case (16) and the upper case (18) by an adhesive agent characterized in that said adhesive agent is applied to the terminal surface (320) of the battery cells to form two lines thereof mainly in the longitudinal direction, and to the lower end surface (330) to form two lines thereof mainly in the width direction. Such a configuration of adhesive agent allows to obtain a sufficient adhesive force respectively between the cell (12) and the upper case (18) and between the cell (12) and the lower case (16) while keeping a small adhesion area.
